Problems solved by technology

At present, there are a variety of spray-free pearlescent effect materials on the market, but because the pearlescent toner often contains metal oxides, its heat dissipation is fast, and the fluidity of the resin material is different due to the fast heat dissipation during the injection molding process, resulting in Parts often have problems such as flow marks

Abstract

The invention provides a spraying-free pearlescent ABS material and a preparation method thereof. The material is prepared form the following components by weight: 40-60 parts of ABS resin, 20-30 parts of PMMA resin, 10-20 parts of AS resin, 1-10 parts of a plasticizer, 0.1-1 part of a heat stabilizer, 0.1-1 part of a lubricant and 1-5 parts of pearlescent toner. The spraying-free pearlescent ABSmaterial prepared according to the invention has good mechanical properties, greatly saves the cost compared with the previous spraying materials, also is environment-friendly and reliable, and has the characteristics of high mechanical properties, easy machining shaping, etc., especially has good appearance, and can achieve the spraying-free effect.

Description

technical field [0001] The invention belongs to the technical field of polymer alloy materials, and in particular relates to a spray-free pearlescent ABS material and a preparation method thereof. Background technique [0002] At present, the application of acrylonitrile-butadiene-styrene graft copolymer (ABS) is more and more widely. It has a series of advantages such as high toughness, good molding processability, and beautiful appearance. However, in some cases, the material It is necessary to achieve the mirror effect without spraying, and ABS resin cannot meet this requirement at this time. Pearlescent color has a beautiful appearance, and spraying is usually used to achieve this appearance before, but the cost of spraying is high on the one hand, and on the other hand, its environmental protection is not enough. Therefore, if there is a kind of spray-free pearlescent effect that can be directly passed through the resin, its application will be greatly improved. At pr...
