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. However, due to the large amount of celluloid and unreasonable formula, the viscosity of the paint is relatively high Large, long time for pearl dyeing, thick surface coating, long drying time, high cost, low work efficiency, and low product yield

Embodiment 1

[0028] Put 0.8 kg of celluloid fragments and 0.08 kg of camphor into a 20-liter container, add 3 kg of acetone, 7 kg of ethyl acetate, and stir. In the process of continuing to stir, add 7 kg of butyl acetate and amyl acetate. 3 kilograms of esters, stirring in a viscous state, then adding 1.2 kilograms of bismuth oxychloride liquid pigments as the main component and stirring until the pigment particles are completely dissolved in the container, and finally a viscous liquid can be obtained, that is, the first time Coating paint.

[0029] Mix celluloid, camphor, ethyl acetate, acetone, butyl acetate and amyl acetate the same as above-mentioned steps, react, but the content of acetone and ethyl acetate that puts in is respectively 2.4 kilograms and 5.6 kilograms, butyl acetate and The content of amyl acetate is 8.4 kilograms and 3.6 kilograms respectively, then add 1.2 kilograms of liquid pigments with bismuth oxychloride as the main component to obtain the second coating.

Embodiment 2

[0034]The difference between this embodiment and embodiment 1 is that the content of celluloid in the first coating paint is 0.8 kg, the content of camphor is 0.1 kg, acetone is 3.2 kg, ethyl acetate is 7.36 kg, and butyl acetate is 8.5 kg , the content of amyl acetate is 3.66 kg, the content of pigment is 1.28 kg; the content of celluloid in the second coating paint is 0.8 kg, the content of camphor is 0.11 kg, the content of acetone is 2.25 kg, and the content of ethyl acetate The content of butyl acetate is 5.25 kg, the content of butyl acetate is 9.45 kg, the content of amyl acetate is 3.05 kg, and the content of pigment is 3 kg; the content of celluloid in the third coating paint is 0.8 kg, the content of camphor is 0.12 kg, acetic acid The content of ethyl ester is 5.46 kg, the content of butyl acetate is 12.55 kg, and the content of the pigment mainly composed of bismuth oxychloride is 0.27 kg. All the other steps are the same as in Example 1.

Embodiment 3

[0036] The difference between this embodiment and Example 1 is that the content of celluloid in the first coating paint is 0.9 kg, the content of camphor is 0.07 kg, acetone is 3.15 kg, ethyl acetate is 7.35 kg, and butyl acetate is 6.93 kg , 2.97 kg of amyl acetate, 0.6 kg of pigment with bismuth oxychloride as the main component; 0.8 kg of celluloid in the second coating paint, 0.1 kg of camphor, and 0.1 kg of acetone and ethyl acetate The content is 2.4 kg and 5.6 kg respectively, the content of butyl acetate and amyl acetate is 8.4 kg and 3.6 kg respectively, then add 1.2 kg of liquid pigment mainly composed of bismuth oxychloride, no third coating is needed, just The artificial pearl with the same effect as in Example 1 can be obtained by repeatedly coating the ball with the first coating material and the second coating material.

Abstract

The invention relates to a surface coating for artificial pearls and a production method. The paint used for artificial pearls of the present invention has no pollution to the environment, and has better effects in terms of color and luster. The composition of the paint of the present invention comprises: 1.5-6% of celluloid, 0.1-0.6% of camphor, and 86% of esterified solvent -95%, pigment 1-8%, wherein the esterification solvent is composed of acetone or a mixture of ethyl acetate and butyl acetate or / and a mixture of amyl acetate, or is composed of ethyl acetate and butyl acetate. The invention provides a non-toxic and harmless artificial pearl coating formula and non-toxic and harmless pearls to the human body, and the pearl dyeing time is short, the drying time is short, the cost is low, the yield is high, and it is suitable for large-scale industrial production 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...
