Abstract

The invention discloses high-heat-resistant high-weatherability ASA / PMMA (acrylonitrile-styrene-acrylonitrile and polymethyl methacrylate) composite and a preparation method thereof, belongs to the field of material modification, and is intended to solve the problem that existing PMMA / ASA alloy resin has Vicat softening point of <100 DEG C and is unable to meet the demand for heat resistance in products and unable to be applied to an environment having high requirement on heat resistance. The composite comprises, by weight, 30-60% of ASA, 30-60% of PMMA, 1-10% of a heat-resistant modifier, 1-5% of a compatibilizer, 1-3% of a black pigment, 0.1-1.5% of a photostabilizer, 0.1-1.5% of an ultraviolet absorbent, 0.1-1.5% of an antioxidant, and 0.1-2% of a lubricant. Actual application shows that the ASA / PMMA composite has excellent heat resistance and weatherability, high surface gloss and good comprehensive properties, has Vicat softening point of 100 DEG C and above, man have effectively extended applicable range, and has a promising application prospect.

Description

technical field [0001] The invention relates to the field of materials, especially the field of material modification, in particular to a high heat-resistant and high-weather-resistant ASA / PMMA composite material and a preparation method thereof.
