Metallic super-toughened PMMA (polymethyl methacrylate) composite material and preparation method thereof

Abstract

The invention discloses a metallic super-toughened PMMA (polymethyl methacrylate) composite material which consists of PMMA, AS (acrylonitrile) resin, a compatilizer, a flexibilizer, an antioxidant, a lubricant, a reinforcing agent and metal powder. The invention also discloses a preparation method of the metallic super-toughened PMMA composite material. The metallic composite material disclosed by the invention has excellent chemical stability and weather resistance, has a strong mechanical performance and has the advantages of high gloss, high surface hardness, resistance to alcohol corrosion, good scraping resistance and the like; and the appearance of the metallic super-toughened PMMA composite material has the same aesthetic effect with that formed by metal spraying.

Description

[0001] Technical field

[0002] The present invention is a high -molecular composite material technology field, which involves a metal texture super tough PMMA composite material and its preparation methods.

[0003] technical background

[0004] At present, the scientific and industrial communities around the world have realized the importance of the coordinated development of engineering plastics and the environment. They are committed to research and development of high cost -effective engineering plastic materials, improve their service life, make full use of their processing advantages, and improve their materialsEnvironmental, such as recycling materials, biomass.From the perspective of market demand, plastic materials will have various colors after processing into various finished products. Most of their colors are made of later spraying, but people's increasingly strong health consciousness requirements are increasingly required to require increasingly COs. 2 Emissions, ...

Examples

Embodiment 1

[0057] Weigh 55 parts of PMMA, 55 parts of AS resin, 5 parts of compatibilizer, 8 parts of toughening agent, 1 part of reinforcing agent, 0.4 parts of antioxidant, and 1 part of lubricant according to the weight ratio, and add them to the low-speed mixer Mixing, put the uniformly mixed material into the hopper of the twin-screw extruder, and then add 1.5 parts of metal toner with an organic coating on the surface into the hopper of the twin-screw extruder by side feeding, and melt Blending, extruding and granulating into metal texture super tough PMMA composite material.
