Low-odor spray-coating-free PC/ABS (polycarbonate/acrylonitrile butadiene styrene) material and preparation method thereof

Abstract

The invention discloses a low-odor spray-coating-free PC / ABS (polycarbonate / acrylonitrile butadiene styrene) material and a preparation method thereof. The material is prepared from the following ingredients including 40 to 80phr of PC, 20 to 60phr of ABS, 5 to 10phr of AS, 0 to 1phr of lubricating agents, 1 to 1.5phr of deodorants, 0.5 to 1phr of heat stabilizers, 0.5 to 1phr of color masterbatch, 0 to 10phr of compatibilizers, 0 to 5phr of processing auxiliary agents, 0.1 to 0.5phr of antioxidants and 0 to 5phr of ultraviolet light absorbers. The material has the low odor and spray-coating-free appearance requirements; the odor grade is lower than or equal to 3.0; the appearance luster is good; the blackness is high; the thermal stability is high; the defects of flowing marks, melting and connecting wires, silver silks and the like cannot be easily generated; the spraying work procedure is omitted; the good spray-coating-free effect is achieved; through the creative selection on raw materials and auxiliary agents and the process innovation, a low-odor spray-coating-free PC / ABS material is produced, and is obviously superior to similar products in the market.

Description

technical field [0001] The invention belongs to the field of plastic blending modification, and belongs to blending modified engineering plastic PC, in particular to a low-odor spray-free PC / ABS material and a preparation method thereof. Background technique [0002] PC / ABS, as the commercialized polymer alloy with the largest sales volume in the world, has been growing at a demand rate of about 10% in recent years. Compared with PC, PC / ABS has improved fluidity, improved processing performance, and reduced product sensitivity to stress, so it is widely used in high-strength, high-heat-resistant parts such as automotive interiors, exteriors, and lights. With the improvement of people's awareness of environmental protection, environmental protection and recycling regulations such as ELV in the automotive industry have been introduced one after another, and raw material manufacturers are also constantly providing new solutions. As a leader in the engineering plastics industry...
