Abstract

The invention relates to a highlight piano black PC / PMMA alloy resin composition and a preparation method thereof. The PC / PMMA alloy resin composition is composed of the following components in partsby weight: 60 to 80 parts of polycarbonate PC resin, 20 to 40 parts of polymethyl methacrylate PMMA resin, 0.1 to 1.0 part of an ester exchange agent, 0.3 to 2.0 parts of black toner and 0.1 to 1.5 parts of an antioxidant. The preparation method comprises the following steps: weighing the components in parts by weight, uniformly mixing to obtain a premix, adding the premix into a double-screw extruder, carrying out melt extrusion, and cooling and granulating to obtain the target product. The obtained PC / PMMA alloy resin has the appearance of highlight piano black, also has excellent toughnessand heat resistance of PC and excellent scratch resistance and weather resistance of PMMA, and can be applied to automotive trim highlight parts.

Description

technical field [0001] The invention relates to an alloy resin composition and a preparation method thereof, in particular to a high-gloss piano black PC / PMMA alloy resin composition and a preparation method thereof. Background technique [0002] Piano black interiors and exteriors of automobiles are increasingly favored by OEMs and consumers, and more and more interiors and exteriors of automobiles adopt piano black design. The cost of spraying piano black paint is high, the yield rate is low, and the spray paint is serious to the environment. However, the use of piano black spray-free materials can obtain the same effect as piano black paint through one-time molding, which greatly reduces production costs and improves production efficiency. Therefore, Piano black paint-free materials are getting more and more attention from the industry. The materials used for piano black spray-free coating of automotive interior mainly include PC, PC / ABS, PA, PMMA / ABS, etc. The poor scra...
