Abstract

The invention discloses a formula of modified polymethyl methacrylate. The formula of the modified polymethyl methacrylate comprises polymethyl methacrylate and additives, wherein the additives include a shock resistance modifying agent, a plasticizer, a filling agent, a wear-resistant agent and a lubricant, the shock resistance modifying agent is a methacrylic acid-butadiene-styrol copolymer, the plasticizer is diisononyl phthalate, the filling agent is talcum powder, the wear-resistant agent is silicon dioxide, and the lubricant is fatty acid amide. According to the formula of the modified polymethyl methacrylate, multiple additives are added in the polymethyl methacrylate, the hardness of the modified polymethyl methacrylate is increased, the surface snags are avoided, the shock strength is improved, and the forming flowing property is good.

Description

technical field [0001] The invention relates to plastic formulations, in particular to a formulation of modified polymethyl methacrylate. Background technique [0002] Polymethyl methacrylate is collectively referred to as acrylic resin, and the corresponding plastics are collectively referred to as polyacrylic plastic, among which polymethyl methacrylate is the most widely used. The abbreviated code name of polymethyl methacrylate is PMMA, commonly known as plexiglass, which is by far the most excellent and relatively affordable variety of synthetic transparent materials. However, polymethyl methacrylate also has great shortcomings, such as low surface hardness, easy to rub hair, low impact resistance, and poor molding fluidity. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a kind of formula of modified polymethyl methacrylate, the formula of this modified polymethyl methacrylate has improved hardness, avoid...
