Problems solved by technology

At this stage, PMMA / ASA alloy materials with metallic texture, high gloss and high weather resistance at home and abroad are mainly sprayed (primer spray + baking, color paint + baking, top paint + baking), and in order to make The product has a metallic texture on the surface, spraying a large amount of pearl powder or metal powder, it is difficult to meet the requirements of environmental protection and product qualification rate, and the existing methods to overcome flow marks are not good for spray-free metal texture high-gloss alloys, so solve this problem Class problems are the problem points that technology needs to break through

Abstract

The invention discloses a spraying-free metal-texture high-gloss high-weather-resistance PMMA / ASA alloy material and a preparation method thereof. AS resin, PMMA resin, ASA rubber powder, glass powder, a pigment and auxiliary agents are mixed and then added into a screw extruder, and the spraying-free metal-texture high-gloss high-weather-resistance PMMA / ASA alloy material is obtained through extrusion. The metal-texture high-gloss high-weather-resistance PMMA / ASA alloy material provided by the invention is a material which can realize a colorful appearance effect without paint spraying treatment, with direct injection molding and without spraying, so that the cost is reduced, the environment is protected, the production process is simple, the product yield is improved, the application prospect is wide, and the PMMA / ASA alloy material has a good use value.

Description

technical field [0001] The invention belongs to the technology of automobile materials, and in particular relates to a PMMA / ASA alloy material with high gloss and high weather resistance of spray-free metallic texture. Background technique [0002] ASA resin is made of acrylonitrile (A), styrene (S), acrylate (A) ternary graft copolymer (also known as AAS), widely used in electronic appliances, automotive industry, outdoor products and other fields. With the improvement of people's aesthetics, the pursuit of different colors is different. In addition to the good weather resistance and colorability of ASA itself, it can be dyed into colorful without fading, and directly processed and injected into colorful products without painting. Painting and electroplating, so ASA materials can be used as outdoor products. PMMA material is one of the directions of high-gloss extrusion products, so an appropriate proportion of PMMA can be added to prepare high-gloss and high surface hardn...
