Light-homogenization modified macromolecular injection molding material and preparation method thereof

Abstract

The invention discloses a light-homogenization modified macromolecular injection molding material which is prepared from the following raw materials by weight: 1.4 to 2 parts of an oxidant 168, 1 to 1.2 parts of a light stabilizer 770, 100 to 130 parts of ABS PA757, 2 to 4 parts of light calcium carbonate, 5 to 7 parts of caprolactam, 2 to 3 parts of oxalic acid, 0.1 to 0.3 part of gamma-aminopropyl-triethoxysilane, 1.7 to 2 parts of polyvinylpyrrolidone, 0.1 to 0.3 part of acetylacetone hexafluoride, 1 to 2 parts of acetylated lanolin, 2 to 4 parts of sodium dodecyl sulfate, 0.5 to 1 part of fatty acid macrogol ester, 0.2 to 0.5 part of alkylated diphenylamine, 5 to 6 parts of dioctyl azelate, 0.3 to 1 part of zinc naphthenate and 4 to 5 parts of micro silica aerogel. The finished product of the light-homogenization modified macromolecular injection molding material is extremely high in transparency, surface hardness and impact strength, high in resistance to yellowing and oxidization, and excellent in comprehensive performance.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to a uniform light modified polymer injection molding material and a preparation method thereof. Background technique [0002] ABS resin is a thermoplastic polymer material with high strength, good flexibility, and easy processing and molding. It has high transparency and excellent gloss. The disadvantage of ABS resin is its low light transmittance. [0003] At present, there are many kinds of ABS on the market, with different appearances, including transparent white background, transparent blue background, transparent yellow background and other colors. The abundant supply provides more choices for people to choose materials. But the making method of the transparent ABS of various colors on the market, or adopt synthetic method or post-dyeing gain, and synthetic method needs particularly large capital investment and abundant technology to make and just can guarantee quality, is dif...

AI Technical Summary

Problems solved by technology

The disadvantage of ABS resin is that its light transmittance is low

But the making method of the transparent ABS of various colors on the market, or adopt synthetic method or post-dyeing gain, and synthetic method needs particularly large capital investment and abundant technology to make and just can guarantee quality, is difficult for popularizing; Although dyeing method It has lower requirements on capital and technology, but it has a greater impact on the transparency of the material and lowers its performance, so it is not the best processing method

[0004] Transparent ABS material has good light transmittance, but it is easily aged by light, heat and oxygen.
