Abstract

The invention discloses a preparation method of a tough scratch-resistant PMMA / ABS suitcase material. PMMA is used to modify ABS to obtain a composite material. A suitcase made of the composite material has the advantages of high surface hardness, high glossiness, scratch resistant property, and low cost, does not need any protective film, and does not need any spraying or electroplating. The material can be applied to one-time injection molding or blister forming, and the steps such as mulching, polishing, grinding, spraying, and the like are not needed. The material has metal luster. Furthermore, the preparation technology is simple, the cost is low, and the ABS surface hardness of obtained PMMA / ABS alloy is improved. The suitcase material has excellent mechanical properties, can be widely applied to electronic products and automobile parts, does not need a conventional plastic surface spraying technology, has a wide application prospect, and generates high social and economical benefits. The provided tough scratch-resistant PMMA / ABS suitcase material promotes the technological development of the suitcase industry.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a preparation method of a strong and tough anti-scratch PMMA / ABS box material. Background technique [0002] ABS is an engineering plastic with excellent comprehensive performance. It can still maintain high impact strength at low temperature. At the same time, it has good dimensional stability, good insulation, wear resistance and oil resistance. It is widely used in daily necessities, household appliances, mechanical parts, Office supplies and communication equipment and other fields. However, pure ABS has some defects, such as: low surface hardness, easy to scratch, high melt viscosity, poor fluidity, poor thermal stability and weather resistance, which limit its further application. Traditional ABS hard-shell boxes are popular among consumers because of their moderate price and light weight. In order to improve the scratch resistance of ABS box shells, luggage manufacturers ...
