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

Embodiment Construction

[0016] The celluloid is dissolved in an ester solvent in advance for later use, and when necessary, pigments are added to the solution to obtain a coating. The pigment used in the invention is composed of mica titanium pearlescent pigment and bismuth oxychloride which can best realize pearl luster, and the components of the pigment include 60-90% of mica titanium pearlescent pigment and 10-40% of bismuth oxychloride according to the weight ratio.

[0017] The weight ratio of acetone and ethyl acetate is preferably 3:7. If too much acetone is added, the peculiar smell of acetone will be increased. Due to the rapid drying of the composition after coating, it cannot be synchronized with other work. On the contrary, If too much ethyl acetate is used, it will take a long time to completely dissolve the celluloid and the gloss will not be good.

[0018] Utilize the resin celluloid that contains camphor in the present invention to replace conventional nitrocellulose as plasticizer; S...

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 coating for shaped products of polymer substances, 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 worn by people are also constantly changing. Among them, artificial pearls that can reflect the quality of natural pearls and can be mass-produced are used in jewelry, rings, collar pins, toys and other fields. more and more widely. 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 the pearl have a good texture and luster, but after people wear it, it...
