Abstract

The invention discloses an anti-aging PC-PMMA plastic alloy composed of the components of, by weight: 100 parts of PC, 16-24 parts of PMMA, 2-4 parts of a compatibilizer, and 0.5-1.5 parts of an anti-aging agent. The anti-aging PC-PMMA plastic alloy provided by the invention has good filling mobility, excellent processing performance, high impact resistance, chemical resistance, high hardness, and scratch resistance. The anti-aging PC-PMMA plastic alloy provided by the invention can be used in communication device housing with high surface hardness and foodstuff packages with high requirement on surface gloss.

Description

technical field [0001] The invention relates to a plastic alloy, in particular to an anti-aging PC-PMMA plastic alloy. Background technique [0002] PMMA is a thermoplastic with excellent weather resistance, high surface hardness, good processing performance, high transparency, light transmittance as high as 91-93%, and 99% of visible light and ultraviolet light. 72%, light weight, with outstanding weather resistance. PC has poor fluidity, is prone to internal stress, is sensitive to notch impact, has poor wear resistance, and has a visible light transmittance of 88%, which can meet the transparency requirements. The heat distortion temperature is as high as 120-143°C, and it has good heat resistance. ; The molding shrinkage rate is only 0.5-0.7%, and the dimensional stability is good; and the impact strength of PC is high. The above two materials are favored by people because of their good light transmittance, flat and clean surface, and the blend has beautiful pearl lust...
