Technical Field

The invention relates to a cold end spraying liquid for a glass bottle and a preparation method thereof, belonging to the technical field of glass coating.

Background

Low-dimensional materials, especially two-dimensional materials, gradually exhibit their own unique advantages, and become popular materials in the fields of electro-optics, chemistry, magnetism, etc. due to their advantages in the aspects of spatial structure, interface properties, etc. Talc, as a silicate mineral, has received great attention because it can be widely used in the fields of paper making, rubber fillers, insulating materials, cosmetics, optoelectronics, and nanocomposite materials. The chemical composition of talc is Mg₃[Si₄O₁₀](OH)₂It has typical layered structure, belongs to an intercalation compound, and the ions in the layers are in a neutralized valence state, and the layers are weak by virtue of weak van der Waals force, so that the layers are not firm, thereby providing possibility for realizing the stripping of the layered talc. At present, many researches related to the peeling of the talc material are carried out, because exchangeable anions and cations exist between layers of the talc material, inorganic ions, organic molecules, ionic surfactants and the like can be subjected to ion exchange with the anions and cations, so that the interlayer structure of raw materials is separated, the peeling purpose is achieved, and the material performance is favorably improved. Early MankoAdachi-Pagaon et al successfully stripped zinc aluminum hydrotalcite with butanol as the specific solvent and dodecyl sulfate as the surfactant. The two-dimensional material obtained by stripping has a thinner layered structure, a larger specific surface area, enhanced surface energy and surface effect, and colloid properties, greatly improves the performances of optics, thermology, electrochemistry and the like, and has wide application prospects in the aspects of preparation of films and functional molecules, catalysis, adsorption and other fields. The invention aims to prepare a stripping material into a dispersion liquid, apply the dispersion liquid to the cold spraying in the glass industry, reduce the collision damage of glass bottles under the condition of low cost and enhance the strength of the glass bottles.

Disclosure of Invention

The invention provides a cold end spraying liquid for glass bottles and a preparation method thereof. In the glass bottle product, the number of glass bottles with scratches was reduced by 56.1% -63% compared to the glass bottles without spraying. The technical scheme of the invention is as follows:

a cold end spraying liquid for a glass bottle is prepared by the following steps:

(1) mixing the laminar talc powder with a strong acid solution, assisting with ultrasonic treatment, wherein the talc layer structure is neutral, and the layers are easy to peel into a thin layer structure due to weak van der Waals force action;

(2) after the mixture after ultrasonic treatment is taken out, washing the mixture to be neutral by ultrapure water;

(3) and (3) carrying out suction filtration and drying on the neutral mixture, adding ultrapure water into the dried sample, wherein the mass ratio of the talc sample to the ultrapure water is 1: 500-5000, and finally adding hexadecyl trimethyl ammonium bromide serving as a coupling agent in a proportion of 0.012-0.12mg/mL to obtain the cold end spraying liquid of the glass bottle.

Further, in the step (1), the lamellar talc is Mg²⁺An intercalated hydrous magnesium silicate mineral; the strong acid solution is hydrochloric acid solution, preferably, the concentration of the hydrochloric acid solution is 0.2-1.0 mol/L; the ultrasonic duration is 1-8 hours.

Further, in the step (3), the neutral mixture after suction filtration is dried for 8 hours in an oven at 80 ℃.

In the invention, the peeling condition of the talc is characterized by XRD, SEM and TEM tests; the invention also comprises the cold end spraying liquid of the glass bottle obtained by the preparation method.

Compared with the prior art, the invention has the following advantages:

(1) the chemical composition of talc is Mg₃[Si₄O₁₀](OH)₂The Mg-Mg alloy has a typical hexagonal reticular layer structure and belongs to Mg²⁺The intercalation compound is weak in the interlayer due to weak van der Waals' force, and thus is weak and easily delaminates into a thin layer structure.

(2) The hydrochloric acid solution is used as the stripping solution of the lamellar talc, and ultrasonic treatment is used for completing stripping, and compared with a single mechanical stripping method, the mechanical force and chemical method has the advantages of simplicity, convenience, easiness, low cost and high stripping efficiency.

(3) In hydrochloric acid solutions with different concentrations, hydrochloric acid enters between the silicon oxide layers of the talc and reacts with magnesium, aluminum and the like, and on the basis of weakening van der Waals force between the silicon oxide layers, the interlayer spacing is increased by means of ultrasound, and finally peeling is achieved.

(4) Compared with the original talc block, the two-dimensional talc material obtained by the stripping method has thinner lamella and has better application prospect when being used as a material for cold spraying of glass.
