Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

As shown in figure 1, the surface treatment method of the jewelry provided by the invention comprises the following steps:

(1) mixing the transparent low-temperature enamel glaze with a curing agent, and then carrying out first heating and drying treatment to obtain an initial glaze. Wherein the curing agent functions to promote the solidification and hardening of the target glaze in the subsequent steps. If the curing agent is lacked, the target glaze cannot be solidified and hardened after being coated on the surface of the jewelry. The first heating and drying process functions to increase the fluidity of the target glaze, thereby facilitating glazing in a subsequent step.

(2) And carrying out vacuum treatment on the initial glaze to obtain the target glaze. Wherein, through carrying out vacuum treatment to the initial glaze, can discharge the bubble in the glaze to obtain the required target glaze of coating.

(3) And coating the target glaze on the surface of the jewelry. The target glaze is coated on the surface of the jewelry in a specific mode by adopting a special tool, so that the surface of the jewelry is full and smooth and is free of bubbles.

(4) And carrying out second heating and drying treatment or air drying treatment on the coated jewelry. And the second heating and drying are carried out on the coated jewelry, so that the solidification and hardening speed of the target glaze can be increased.

When in use, the surface treatment method of the jewelry can simply, rapidly and efficiently carry out glazing treatment on the surface of the jewelry, and the treated jewelry can clearly show the surface effect or texture (such as metal surface effect or texture) of the jewelry under the enamel, thereby not only keeping the unique effect of the surface of the jewelry, but also adding clear and colorful colors, being simple, rapidly and efficiently and having good safety.

In a particular embodiment, the low-temperature enamel glaze comprises polyepichlorohydrin, which is preferably used for the surface treatment of jewelry and is safe since polyepichlorohydrin does not contain harmful elements which have an effect on the human body.

In a particular embodiment, the curing agent comprises: the mixture of dimethyl, nonyl phenol, aminomethyl, methylene-bis-group and benzyl alcohol, the curing agent and the low-temperature enamel glaze have good uniform mixing effect, and can prevent the target glaze from accelerating solidification and drying or from being incapable of solidifying and hardening. The mixture of dimethyl, nonyl phenol, aminomethyl, methylene biradical and benzyl alcohol does not contain harmful elements which have influence on human body, so that the safety is good.

In one particular embodiment, the low temperature enamel frit is mixed with a curing agent according to a ratio of 5: 2-4: 1.5 weight ratio for uniform mixing. For example, by stirring to mix the two uniformly. If the mixing of the low-temperature enamel glaze and the curing agent is not uniform, the target glaze is agglomerated and heated unevenly. The proportion of the low-temperature enamel glaze and the curing agent can be set according to actual needs. If the content of the low-temperature enamel glaze is too large, the target glaze obtained by mixing is too viscous, and the distribution of the low-temperature enamel glaze in the target glaze is not uniform. If the content of the curing agent is too large, the target glaze material is accelerated to solidify and dry, and the target glaze material cannot be used. Preferably, the low-temperature enamel glaze and the curing agent are mixed according to a ratio of 5: 2, the low-temperature enamel glaze has good distribution uniformity in the target glaze and good solidification effect of the target glaze.

In a particular embodiment, the step of mixing the low-temperature enamel glaze with the curing agent followed by a first heating and drying treatment to obtain an initial glaze comprises: and uniformly mixing the low-temperature enamel glaze with a curing agent, and putting the mixture into an oven for baking for a certain time to obtain the initial glaze.

In a specific embodiment, the baking temperature of the oven is 70-100 ℃. The baking time of the oven is 3-5 minutes. Specifically, if the process temperature is too low, the initial glaze surface is not glossy and does not flow. If the temperature is too high in the process, the initial glaze is directly solidified and cannot be used. If the process time is too short, the initial glaze surface is not glossy and the fluidity is poor. If the process is too long, the initial glaze is solidified and hardened, and cannot be used. Preferably, the baking temperature of the oven is 85 ℃, the baking time of the oven is 4 minutes, and the surface gloss of the initial glaze is good and the fluidity is good.

In a particular embodiment, the step of subjecting the initial glaze to vacuum treatment to obtain the target glaze comprises: and discharging bubbles in the initial glaze material in a negative pressure vacuumizing mode to obtain the target glaze material. Through the evacuation, can effectively eliminate the bubble that produces in low temperature enamel frit and the curing agent stirring process, improve the quality of target glaze to can reduce the bubble on the surface of ornament when using, easily glazing.

In a specific embodiment, the vacuum pumping time is 5 to 10 minutes, and the vacuum degree is minus 0.1 mpa, so that bubbles generated during the stirring process of the low-temperature enamel glaze and the curing agent can be effectively eliminated. Specifically, at normal temperature (20-25 ℃), the low-temperature enamel glaze and the curing agent are uniformly mixed and then are placed into a vacuum extractor for vacuum-pumping for 5-10 minutes, the vacuum degree is minus 0.1 MPa, bubbles in the initial glaze can be effectively discharged, and the target glaze after the bubbles are discharged can be simply and efficiently obtained. Preferably, the vacuumizing time is 7.5 minutes, the vacuum degree is minus 0.1 MPa, bubbles generated in the stirring process of the low-temperature enamel glaze and the curing agent can be effectively eliminated, and the stability is good.

In one particular embodiment, the step of applying the target glaze to the surface of the jewelry comprises: glazing is carried out by adopting a special tool according to a mode of a small number of times and the same direction. Specifically, the toothpick or the embroidery needle is adopted for glazing in a mode of a small amount of times and the same direction, so that the surface of the jewelry can be full and smooth and is free of bubbles. For example, the target glaze is uniformly coated on the surface of the jewelry in the same direction (for example, all directions of upward, downward, leftward or rightward) by using toothpicks or embroidery needles for more than three times, and the workpiece is ensured not to have large vibration during operation. Wherein the glazing amount is 0.005-0.01 g each time.

In a preferred embodiment, the jewelry is made of a metal material. When in use, the target glaze is uniformly coated along the metal surface of the jewelry, so that the metal surface effect or texture under the enamel can be clearly shown, the unique effect of the jewelry surface can be kept, and the clear and colorful colors are added.

In one embodiment, the step of subjecting the coated jewelry piece to the second heating and drying process comprises: and placing the coated jewelry into a first drying oven to be baked for a certain time.

In a specific embodiment, the jewelry with the target glaze is fixed on a clamp and placed into a first drying oven at the temperature of 70-100 ℃ for baking for 40-60 minutes. Specifically, if the temperature in the process is too low, the surface of the treated target glaze is not smooth enough and is not flat. If the temperature in the process is too high, the color of the treated target glaze is changed and is not bright enough. If the process time is too short, the treated target glaze surface is not glossy. If the process time is too long, the color of the treated target glaze material has color difference and is easy to crack. Preferably, the baking temperature of the first drying oven is 85 ℃, the baking time of the first drying oven is 50 minutes, so that the surface of the treated target glaze is smoother, smoother and glossy, and the stability is good.
