Abstract

The invention discloses a high-gloss spraying-free polymethyl methacrylate (PMMA) composition. The composition comprises, by weight, 35 to 60 parts of PMMA resin, 30 to 60 parts of ASA resin, 20 to 40 parts of polyaryl phosphate, 5 to 20 parts of a toughening agent, 0.3 to 1.0 part of a lubricating agent, 0.2 to 1.5 parts of PEEK resin and 1 to 5 parts of an ABS-g-MAH compatilizer. The invention belongs to the technical field of high polymer materials, and particularly relates to the high-gloss spraying-free PMMA composition which is excellent in weather resistance, mechanical strength and flame retardance, good in heat insulation property, high in gloss and scratch-resistant.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and specifically refers to a high-gloss spray-free polymethyl methacrylate PMMA composition. Background technique [0002] Today's automobile industry is developing rapidly, and automobiles are the most common and important type of modern transportation. The use of plastic materials to replace various non-ferrous metals and alloy steels in the automotive field is becoming more and more extensive. The average plastic used in each car in developed countries such as Japan, the United States and Germany has exceeded 100 kilograms, accounting for 8% of the total weight of the car on average. , The average amount of plastic used in each car in China is 70 kg, accounting for an average of 6% of the total weight of the car. The application of plastic materials in the automotive field makes the design of auto parts more flexible, and at the same time reduces the cost of parts processing, assemb...
