Problems solved by technology

However, the solubility and dispersibility of the nitrocellulose, titanium dioxide and bismuth oxychloride used in the above-mentioned technology are not good. Ideal luster and texture can be obtained with specific pigments, but the manufacturing process is complicated, and the composition and content of these substances do not meet the conditions, and the lack of exquisite texture like natural pearls reduces the overall product value.
In addition, as conventional bead materials, thermoplastic resins such as acrylic, ABS, PS, and High Impact are widely used on beads, and most of the surfaces are not coated. Very sensitive to chemicals when coating and therefore does not reflect its commercial value
[0003] Chinese patent ZL200410024243.5, titled "Coating Method and Paint for Resin Balls for Artificial Pearls", discloses a method for surface treatment and coating of resin balls with a paint that does not contain lead, but due to its celluloid Large dosage and unreasonable formula lead to high viscosity of paint, long pearl dyeing time, thick surface coating, long drying time, high cost, low work efficiency, and low yield of products

Embodiment 1

[0031] Put 0.8 kg of celluloid fragments in a 20-liter container, add 7 kg of acetone, 7.5 kg of ethyl acetate, 1.2 kg of benzene, 3.5 kg of butyl acetate, and 0.1 kg of camphor. The pellets are put into the surface treatment paint to surface treat the pellets.

[0032] Put 0.8 kg of celluloid fragments and 0.07-0.08 kg of camphor in a 20-liter container, then add 10 kg of ethyl acetate, stir, then add 10 kg of amyl acetate, continue stirring, and then add bismuth oxychloride as the main component Stir 1-1.5 kg of liquid pearl pigment to dissolve the pigment particles in the container to obtain a viscous liquid that is the first coating, and put the surface-treated thermoplastic balls into the first coating for coating , and then take out the ball and let it dry for 20-30 minutes at 45 degrees Celsius.

[0033] Put 0.8 kg of celluloid fragments and 0.08-0.09 kg of camphor in a 20-liter container, then add 8 kg of ethyl acetate, stir, then add 12 kg of amyl acetate, continue s...

Embodiment 2

[0037] The difference between this embodiment and Example 1 is that the content of celluloid in the surface treatment coating is 0.8 kg, the content of acetone is 4.8 kg, the content of ethyl acetate is 12.6 kg, the content of butyl acetate is 6.08 kg, and the content of camphor The content of benzene is 0.07-0.12 kg, and the content of benzene is 0.96 kg.

[0038] The content of celluloid in the first coating paint is 0.9 kg, the content of camphor is 0.07-0.09 kg, the content of ethyl acetate is 10.5 kg, the content of amyl acetate is 10.2 kg, and the content of pigment is 3 kg.

[0039] The content of celluloid in the second coating paint is 0.9 kg, the content of camphor is 0.09-0.12 kg, the content of ethyl acetate is 7.5 kg, and the content of amyl acetate is 12 kg. The pigment mainly composed of bismuth oxychloride The content is 1.5 kg.

[0040] In this embodiment, the third coating process is omitted, and the pearl coating is completed after the artificial pellets ar...

Embodiment 3

[0042] The difference between this embodiment and Embodiment 1 is that this embodiment omits the steps of the first coating and the second coating, and the third coating is used repeatedly for 3 times to complete the production of artificial pearls.

[0043] The content of celluloid in the third coating paint is 0.8 kg, the content of camphor is 0.08-0.1 kg, the content of ethyl acetate is 8 kg, the content of amyl acetate is 15.68 kg, and the content of pigment is 0.32 kg.

Abstract

Paint for resin micro-ball of artificial pearl and its coating method are disclosed. The paint consists of celluloid, acetic ether, banana oil, camphor and pigment. The procedure is carried out by surface treating for resin micro-ball by surface curing agent and coating for at least twice. It has short dyeing and drying time, clean surface and good luster,

Description

technical field [0001] The invention relates to a process for producing decorative effects, in particular to a process for a coating method of artificial pearls. Background technique [0002] The prior art is to dissolve nitrocellulose in solvents such as acetone or butyl acetate, and then use bismuth oxychloride which is harmless to the human body to replace the original pigment to dye the pearl balls. However, the solubility and dispersibility of the nitrocellulose, titanium dioxide and bismuth oxychloride used in the above-mentioned technology are not good. Ideal luster and texture can be obtained with specific pigments, but the manufacturing process is complicated, and the content conditions of each component and these substances do not meet the conditions, lacking the exquisite texture like natural pearls, and reducing the overall product value. In addition, as conventional bead materials, thermoplastic resins such as acrylic, ABS, PS, and High Impact are widely used o...
