Coating for imitation pearl

Abstract

The invention relates to a surface coating for imitation pearls, comprising a plurality of components in weight percentage: celluloid 1 to 6 percents, esterified compound solvent 86 to 96 percents, pigments 1 to 8 percents, and camphor 0.1 to 0.6 percents; wherein, the esterified compound solvent is composed of acetone, ethyl acetate, butyl acetate, and amyl acetate, or formed by ethyl acetate and butyl acetate. The surface coating for imitation pearls is characterized in that mica coated by titanium dioxide is arranged in the pigments. The surface coating for imitation pearls provides a nonpoisonous preparation method for the coating of the imitation pearls as well as a nonpoisonous pearl, and has the advantages of no pollution to the environment, better color and luster, short dyeing and drying time, low cost, high yield, and suitability to industrial large-scale production.

Description

Technical field [0001] The invention belongs to the technical field of coatings for polymer shaped products, and in particular relates to a surface coating for artificial pearls. Background technique [0002] With the development of modern technology and the improvement of people’s living standards, the decorations people wear are constantly changing. Among them, artificial pearls that can reflect the quality of natural pearls can be mass-produced in jewelry, rings, pins, toys and other fields. More and more widespread. In the prior art, the manufacture of artificial pearls is generally to dissolve nitrocellulose in various solvents, and then add pigments in the solution to coat the resin beads. Most of the pigments in the above ingredients are in the hydroxide containing lead. The compound of sexual salt and alkaline lead carbonate, the use of this compound can make the pearl have a good texture and luster, but after people wear it, it will cause harm to the human body and cause...

AI Technical Summary

Problems solved by technology

In the prior art, artificial pearls are generally made by dissolving nitrocellulose with various solvents, and then adding pigments in the solution to coat the resin beads. Most of the pigments in the above ingredients are hydroxides containing lead components. The compound of alkaline salt and alkaline lead carbonate, the use of this compound can make pearls have a good texture and luster, but after people wear it, it will cause harm to the human body and cause pollution to the environment has become a problem that is difficult to solve

[0003] Chinese patent ZL200410024173.3, titled "Paint for artificial pearls and its production method", discloses a paint and production method that does not contain lead, but because the pigment uses bismuth oxychloride, bismuth oxychloride is used for pearl For pigments, it is generally high-purity bismuth oxychloride, which has high cost, low work efficiency, and low yield of products
