Embodiment 1

[0014] It is made of the following ingredients by weight: First, dissolve 5 parts of ABS resin in 85 parts of dichloromethane to make ABS polymer solution, add 5 parts of pearlescent pigment powder, 0.5 part of dicumyl peroxide under constant stirring , 2.5 parts of maleic anhydride, 1 part of antioxidant 1010, 1 part of antioxidant 168, after fully stirring evenly, a composite component paste with 5% relatively low viscosity of pearlescent pigment is obtained.

[0015] Mix the above-mentioned compound component paste with the ABS resin to be colored in a high-mixer at a weight ratio of 3 to 5 per thousand, and then dry it at 80 degrees Celsius for 4 hours, and then make injection molding samples preparation.

Embodiment 2

[0017] First, dissolve 10 parts of ABS resin in 75 parts of acetone solution to make ABS polymer solution, add 10 parts of pearlescent pigment powder, 0.5 parts of dicumyl peroxide, 2.5 parts of maleic anhydride, 1 part of anti Oxygen 330, 1 part of antioxidant 1084, after fully stirring evenly, a composite component paste of 10% pearlescent pigment with medium viscosity is obtained.

[0018] The added pearlescent pigment is that the surface of the flake substrate is coated with pigment, the substrate is mica sheet or glass sheet, the particle size of the substrate is 10um-80um, and the pigment is iron oxide or aluminum oxide. The ABS in the paste composite component body is selected from conventional pure resin, Chimei PA-707 or PA-747

[0019] Mix the above-mentioned compound component paste with the ABS resin to be colored in a high-mixer at a weight ratio of 3 to 5 per thousand, and then dry it at 80 degrees Celsius for 4 hours, and then make injection molding samples pre...

Embodiment 3

[0021] First, dissolve 10 parts of ABS resin in 70 parts of dimethylformamide to form an ABS polymer solution, add 15 parts of pearlescent pigment powder, 0.5 parts of dicumyl peroxide, 2.5 parts of maleic anhydride, 1 1 part of antioxidant 264, 1 part of antioxidant 1084, after fully stirring evenly, a composite component paste with 15% of pearlescent pigments and relatively high viscosity is obtained.

[0022] Mix the above-mentioned composite component paste with the ABS resin to be colored at a ratio of 3 to 5 per thousand in a high-mixer, and then dry it at 80 degrees Celsius for 4 hours before preparing injection molding samples.

[0023] The present invention is not limited to the combination of the above three embodiments, and the actual implementation can properly adjust the content of the pigment in the composite component according to the type and amount of the pigment added in order to achieve the best effect.

Abstract

The invention relates to a method for solving dust pollution caused by pearlescent pigment applied to ABS coloring. The method comprises the following steps: preparing ABS into an organic solution form, adding the pearlescent pigment, a chemical modifier and a stabilizer in the ABS organic solution, stirring and mixing uniformly to prepare a pasty composite component body, mixing the pasty composite component body and the solid ABS particles needing to be colored according to a ratio, and heating and mixing, wherein the liquid solvent in the pasty composite component body is gradually volatilized, the ABS in the pasty composite component body enables the surfaces of the solid ABS particles to be coated with the pearlescent pigment, the chemical modifier and the stabilizer, the coloring process of the solid ABS particles is completed, and the method can be directly applied to production of ABS injection-molded products.

Description

technical field [0001] The invention relates to a method for solving dust pollution when pearlescent pigments are used for ABS coloring, and belongs to the technical field of plastic coloring. Background technique [0002] At present, spray-free technology has been rapidly promoted in the plastics industry, and this technology can prepare plastic products with metallic luster. Compared with the traditional electroplating technology, the spray-free technology does not need to invest in special equipment for electroplating, does not require solvents, and will not cause environmental pollution. The spray-free technology is mainly to add some pearlescent pigments made of mica coated with metal oxides into the plastic matrix, so that the plastic can obtain metallic luster and pearlescent effect after molding. ABS resin is widely used in the electrical industry due to its good molding dimensional stability and relatively balanced mechanical properties. The one-time injection mol...
