Problems solved by technology

[0002] PMMA resin has good transparency, strength, and chemical resistance. It is widely used in home appliances and food fields, but its notched impact strength is low and toughness is poor.
Compared with some plastic products, ordinary ABS products have a lower surface hardness, which limits their application in some fields. Although there are other types of resins on the market with ideal surface hardness, these resins have improved surface hardness and mechanical strength at the same time. Decreased performance, on the other hand, the price is expensive, resulting in an increase in product cost
And it does not have the ability to resist ultraviolet rays and is easy to age

Abstract

The invention discloses a high-hardness and anti-impact PMMA/ABS (Polymethyl Methacrylate/Acrylonitrile Butadiene Styrene) composite sheet material. The high-hardness and anti-impact PMMA/ABS composite sheet material is prepared from the following components in parts by weight: 10 to 50 parts of PMMA resin, 20 to 70 parts of ABS resin, 1 to 15 parts of MBS (Methacrylate-Butadiene-Styrene) resin, 0.5 to 3 parts of polyester grafted modified silicone auxiliary agent, 0.2 to 0.8 part of compatilizer, 0 to 0.5 part of dispersant, 0 to 1 part of antioxidant and 0 to 0.3 part of ultraviolet absorbent UV-531. The high-hardness and anti-impact PMMA/ABS composite sheet material disclosed by the invention combines advantages of two types of plastic and makes up the respective disadvantages; the PMMA and the ABS are commixed and other additives are added; compared with common PMMA resin, the surface hardness of the obtained PMMA/ABS material is improved by 20 percent to 30 percent; meanwhile, the PMMA has a more excellent anti-impact performance; the polyester grafted modified silicone auxiliary agent is added into to the PMMA raw material so that the surface scraping resistance, abrasion resistance, smoothness and hydrophobic property of the PMMA are improved and surface friction coefficients are reduced; an anti-scratching protection layer does not need to be arranged on the surface of a PMMA plate, so that the process can be effectively simplified, the production efficiency is improved and the production cost of enterprises is reduced; meanwhile, the high-hardness and anti-impact PMMA/ABS composite sheet material has a good ultraviolet-proof performance and the service life of the sheet material is prolonged.
