Background

An optical fiber, i.e. an optical fiber, is a transmission medium for transmitting information from one end to the other end based on the principle of total reflection of light, and is generally made of glass or plastic. In the process of installing the optical fiber, the two ends of the optical fiber are not exposed to the external environment, so that the optical fiber is difficult to identify, and the optical fiber is mainly made of glass or plastic, so that the optical fiber cannot be judged by electrical equipment. Therefore, in order to facilitate identification of the optical fiber and splicing of the optical fiber during the cable laying process, identification of the optical fiber is required. At present, the optical fiber is usually coated with a layer of optical fiber ink on the outer surface of the optical fiber to color the optical fiber for identification.

The existing ink has single color, the common colors are 12, if 24 cores and more than 24 optical fibers are prepared, the outer surfaces of at least two optical fibers are coated with the same ink, and the ink needs to be processed.

In the prior art, the same color is identified by a method of adding a color ring in multiple ways, namely, the color ring is arranged on one of two optical fibers with the same color, so that a process is added, the regularity of a coating is influenced due to the introduction of the color ring, the abrasion of the optical fibers is increased, and the attenuation of optical signals is possibly increased. On the other hand, the ink can also have a fluorescent effect by adding a fluorescent dye into the ink, but the fluorescent dye is ground before the fluorescent dye is added into the ink so that the particle size of the fluorescent dye reaches the particle size required by international standards, and then the fluorescent dye is added into the ink, but the elasticity of the coating of the optical fiber prepared by the method is poor, the strength of the coating is weakened, and the signal attenuation of the prepared optical fiber is large.

Detailed Description

Unless defined otherwise, all technical terms used in the examples of the present invention have the same meaning as commonly understood by one of ordinary skill in the art.

Before explaining the embodiments of the present invention in detail, an application scenario of the embodiments of the present invention will be described.

The optical fiber is widely used in the fields of communication, medicine, decoration, automobiles, ships and the like, and has the advantages of wide frequency band, small loss, light weight, high speed, strong anti-interference capability and the like. The optical fiber comprises a bare fiber and a resin coating, wherein the bare fiber comprises a fiber core and a cladding, and the resin coating comprises an inner layer, an outer layer, an ink layer and a ribbon layer. Because the bare fiber is brittle and easy to break and is easy to scratch by moist gas and external force, at least one layer of resin coating is often coated on the surface of the bare fiber, and the coating is helpful for preventing the loss of optical fiber signals, prolonging the service life of the optical fiber and improving the performance of the optical fiber.

As optical fibers enter subscriber loop systems, the demand for fiber core count is increasing due to the increasing demand for fiber speed from the systems, particularly for high core count cable systems and ribbon cable systems, and the demand for 24-core, 36-core, or more ribbon fibers is increasing. Most of the commonly used ribbon optical fibers at present are composed of 12 cores, each of the 12 colors accounts for 1, and if 24 cores or more ribbon optical fibers are prepared, the optical fibers with the same color need to be processed and identified. The processing identification method adopted at present is to add a color ring, i.e. to punch a color ring on one of two optical fibers with the same color, if 36 cores are adopted, 2 color rings are needed to be punched, thus increasing the process flow. In view of this, embodiments of the present invention provide an ink, which can solve the above technical problems.

In a first aspect, embodiments of the present invention provide an ink, including: at least one optical brightener, at least one acrylate oligomer, and at least one acrylic monomer.

According to the ink provided by the embodiment of the invention, the fluorescent whitening agent has a vinyl bond or an oxazole group, a fluorescent effect can be generated after light irradiates on the fluorescent whitening agent, and the fluorescent whitening agent cannot influence the performances such as elasticity and strength of an ink layer in the mass percentage range; based on CH in acrylate oligomers2The CHCOOR structure enables the cured ink to have high wear resistance, flexibility and adhesion; based on CH in acrylic monomers2Since the acrylic monomer has a low molecular weight, when it is mixed with a high molecular weight acrylate oligomer, the viscosity of the acrylate oligomer can be effectively reduced, and the viscosity of the ink system can be reduced to adjust the crosslinking density of the ink system. Through the synergistic compounding of the components, the invention can provideThe ink not only has a fluorescent effect, but also has good compatibility with other components in the ink, and can keep the original properties of elasticity, strength and the like of an ink layer prepared from the ink unchanged.

It is noted that the at least one fluorescent whitening agent indicates one or at least two kinds of fluorescent whitening agents, the at least one acrylate oligomer indicates one or at least two kinds of acrylate oligomers, and the at least one acrylic monomer indicates one or at least two kinds of acrylic monomers.

When the components are in the proportion range, the components can cooperate with each other, so that the ink has good curing degree, mechanical strength, low attenuation and other properties, and also has a fluorescent effect under ultraviolet irradiation, and is easy to distinguish.

In the examples of the present invention, the degree of cure is the percentage of the acrylate unsaturated groups in the acrylate oligomer reacted to the total acrylate unsaturated groups in the acrylate oligomer. The degree of cure is directly related to the properties of the optical fiber prepared using the ink, such as mechanical properties, in-situ modulus, fatigue strength, and the like. Generally, the higher the degree of cure of the optical fiber, the better the overall performance.

Optionally, the ink further comprises an auxiliary agent, wherein the auxiliary agent can be selected from one or more of a photoinitiator, an active amine co-initiator, a leveling agent, a defoaming agent and a dispersing agent.

The photoinitiator is also called a photosensitizer or a photocuring agent, and is a compound capable of absorbing energy with a certain wavelength in an ultraviolet region (250-420 nm) or a visible light region (400-800 nm) to generate free radicals, cations and the like so as to initiate polymerization, crosslinking and curing of monomers. By adding the photoinitiator in the ink layer, the crosslinking degree of the ink system can be increased, and the curing degree of the ink system is further improved.

It is noted that the active amine co-initiator can effectively inhibit the ink system from generating oxygen inhibition effect, so that the ink system can achieve better curing effect. The leveling agent is a common paint auxiliary agent and can promote the paint to form a flat, smooth and uniform coating film in the drying film-forming process. The defoaming agent is a substance that suppresses the generation of foam or eliminates foam that has been generated. The dispersant can reduce the time and energy required for the dispersion process, stabilize the dispersed pigment dispersion, modify the surface properties of the pigment particles, and adjust the mobility of the pigment particles, thereby shortening the dispersion time of the pigment molecules, and further improving the glossiness, the tinting strength and the hiding power, and improving the color development and the color tone, preventing floating and floating, preventing flocculation, and preventing sedimentation.

Notably, the auxiliary agent may be one of photoinitiators; the auxiliary agent can also be a mixture of a photoinitiator and a reactive amine co-initiator, and the mixing proportion can be 1: 1; the auxiliary agent can also be a mixture of three of a photoinitiator, an active amine co-initiator and a defoaming agent, and the mixing proportion can be 2: 1: 1.

It should be noted that the photoinitiator is also called a photosensitizer or a photocuring agent, and is a compound capable of absorbing energy with a certain wavelength in an ultraviolet light region or a visible light region to generate free radicals, cations and the like, so as to initiate polymerization, crosslinking and curing of monomers. By adding the photoinitiator in the ink layer, the crosslinking degree of the ink system can be increased, and the curing degree of the ink system is further improved. For example, the photoinitiator in the ink provided by the embodiment of the present invention may be one of radical initiators; the photoinitiator may also be a mixture of both a radical initiator and a cationic initiator, and, for example, the mixing ratio may be 2: 1.

The free radical initiator has a faster curing rate than the cationic initiator and the anionic initiator, and is more suitable for use in ink systems requiring high-speed curing. For example, the radical initiator in the ink provided by the embodiment of the present invention may be one of 2,4, 6-trimethylbenzoyldiphenylphosphine oxide; the free radical initiator can also be a mixture of three components of 2,4, 6-trimethylbenzoyl diphenyl phosphine oxide, 1-hydroxycyclohexyl phenyl ketone and benzophenone, and the mixing ratio is 2: 3: 2; the free radical initiator can also be a mixture of three of 2,4, 6-trimethylbenzoyl diphenyl phosphine oxide, 2-methyl-1- [4- (methylthio) phenyl ] -2- (4-morpholinyl) -1-acetone and benzophenone in a mixing ratio of 2: 2: 3 or 2: 2: 2.5; the free radical initiator can also be a mixture of three of 2,4, 6-trimethylbenzoyl diphenyl phosphine oxide, 2-hydroxy-2-methyl-1-phenyl-1-acetone and benzophenone in a mixing ratio of 2: 2: 3; the free radical initiator can also be a mixture of three of 2-methyl-1- [4- (methylthio) phenyl ] -2- (4-morpholinyl) -1-acetone, 2-hydroxy-2-methyl-1-phenyl-1-acetone and benzophenone in a mixing ratio of 3: 2: 3.

The titanium dioxide provided in the embodiment of the invention is inorganic toner, and the carbon black, the phthalocyanine blue, the phthalocyanine green, the benzidine yellow, the precious red 4B, the permanent violet or the permanent red are organic toner. For example, the toner in the ink provided by the embodiment of the present invention may be one of phthalocyanine blue; the toner may also be one of phthalocyanine green; the toner can also be one of permanent red; the toner may also be one of carbon black; the toner can also be one of benzidine yellow; the toner can also be one of titanium dioxide; the toner can also be a mixture of titanium dioxide, benzidine yellow and permanent red, and the mixing proportion can be 5: 4: 1; the toner can also be a mixture of titanium dioxide, phthalocyanine blue and green, and the mixing proportion can be 5: 2: 3.

The organic silicon leveling agent or the acrylic leveling agent provided by the embodiment of the invention migrates to the surface of the ink layer through compatibility, so that the surface properties such as the interfacial tension of the ink layer are influenced, and the ink layer obtains good leveling property. For example, the leveling agent in the ink provided by the embodiment of the present invention may be one of organic silicon leveling agents; the leveling agent can be a mixture of an organic silicon leveling agent and an acrylic leveling agent, and the mixing ratio can be 1: 1. the embodiment of the present invention is not limited to the combination of the leveling agents, and the ratio of the combination of the components of the leveling agent is not limited to the combination.

Optionally, the active amine co-initiator can effectively inhibit the ink system from generating an oxygen inhibition effect, so that the ink system achieves a better curing effect. Illustratively, the reactive amine co-initiator in the ink provided by the embodiment of the present invention may be an acrylated reactive amine co-initiator.

The properties of the inks and colored optical fibers measured during the test are shown in table 9 below:

TABLE 9

By comparing examples 1, 2, 3 and 4 with comparative example 1, it can be seen that in comparative example 1 where the acrylate oligomer content is 30%, the elongation at break V of the colored optical fiber is lower, the degrees of curing G1200 and G1500 are lower, and the signal attenuation a is higher, and thus it can be seen that when the acrylate oligomer content should be lower than 30% by mass of the formulation, the ink system has no advantage in performance, and when the acrylate oligomer content in the ink system described in the present invention is in the range of 35% to 80%, the elongation at break V of the colored optical fiber is faster, the degrees of curing G1200 and G1500 are higher, and the signal attenuation a is lower.

By comparing examples 1, 2, 3 and 4 with comparative example 2, it can be seen that the fluorescent green powder added in comparative example 2 has a particle diameter d increased by more than 5 times compared with examples 1 to 4, an elongation at break V decreased by more than 40%, and the degrees of curing G1200 and G1500 were also significantly smaller, and the signal attenuation a was significantly increased.

Therefore, the ink provided by the embodiment of the invention has a lower particle size and a higher elongation at break V, and the colored optical fiber prepared by the ink provided by the embodiment of the invention also has better curing degree and attenuation performance.

As can be seen from Table 9, in comparative example 3 in which the amount of the fluorescent whitening agent added was 3%, the degrees of cure G1200 and G1500 and the signal attenuation a of the colored optical fiber were also slightly affected.

Therefore, the fluorescent whitening agent in the colored optical fiber provided by the embodiment of the invention can be well compatible with the ink system, and the addition amount of the fluorescent whitening agent is less than 3%, and the colored optical fiber still has lower signal attenuation a, and is preferably not more than 2.5%.

The fluorescent whitening agent with the mass percentage is added for more clear expression, so that the colored optical fiber can obviously generate a fluorescent effect, and the colored optical fiber is further identified and distinguished. Further description is made by applying examples 2-17.

The optical fiber A is a self-made optical fiber, the fiber core and the cladding of the optical fiber A are made of silicon dioxide, and the inner layer coating of the optical fiber A is an optical fiber inner layer coated with resin series products KG 100-1D; the outer coating is an optical fiber outer coating resin series product KG 200-2. The diameter of the fiber was about 245 μm. The optical fiber B is a self-made optical fiber, the material of the fiber core and the material of the cladding are both silicon dioxide, and the inner layer coating of the optical fiber is the optical fiber inner layer coated with the resin series product KG 100-1Y-1; the outer coating is an optical fiber outer coating resin series product KG 200-2Y. The diameter of the fiber was about 245 μm.

And taking out the half bottle of blue ink, adding 0.5 mass percent of fluorescent brightener PEB into the taken-out half bottle of blue ink, uniformly stirring to obtain mixed ink, and finishing coloring and curing the mixed ink on the surface of a part of the optical fiber A by using a UV lamp tube with 7500W power through an optical fiber coloring machine at the speed of 1200m/min and the diameter of 0.260mm to form the fluorescent recognizable blue colored optical fiber containing the fluorescent brightener PEB, wherein the part of the optical fiber A is replaced by a No. 1 optical fiber. And (3) carrying out coloring and curing on the surface of a part of the B optical fiber by using a UV lamp tube with the power of 7500W through an optical fiber coloring machine by using the half bottle blue ink without adding the fluorescent whitening agent PEB at the speed of 1200m/min and the diameter of 0.260mm to obtain a common blue optical fiber, and replacing the part of the B optical fiber by a No. 2 optical fiber.

Therefore, the colored optical fiber provided by the embodiment of the invention can perform fluorescence identification.

Watch 13

As can be seen from table 13, when the ink layer of the colored optical fiber contains the fluorescent whitening agent, no matter whether the type and content of the fluorescent whitening agent are the same or not, the colored optical fiber has a fluorescent effect when irradiated by the fluorescent detection pen, which is convenient for identification.

Application example 17

This application example 17 provides a method for preparing a 24-core ribbon optical fiber including a conventional 12-color ink and 12 colors of inks added with a fluorescent brightener, which comprises the following steps:

Wherein, the mass percentage of the fluorescent whitening agent added to each optical fiber ink layer is 0.5%. The 24-core ribbon fiber prepared in example 17 of this application was irradiated using a fluorescence detection pen with a wavelength of 330-410 nm. The detection results are as follows: in the 24-core ribbon optical fiber, the 12-color A colored optical fiber added with the fluorescent whitening agent shows blue fluorescence under a fluorescence detection pen, and the 12-color B colored optical fiber not added with the fluorescent whitening agent has no obvious change under the fluorescence detection pen. It can be seen that the ink provided by the embodiment of the invention can simply distinguish the 24-core optical fiber.

The above description is only illustrative of the present invention and should not be taken as limiting the invention, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention should be included in the scope of the present invention.
