Problems solved by technology

For example, currently widely used plastic products use ABS as the main component, compounded with polymers such as PMMA, PVC or PC, and have the characteristics of impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. However, , ABS plastic has poor weather resistance and is not suitable for outdoor products, which is a big limitation for it

[0031] After blending the ingredients according to the formula shown in Table 1 below, stir and mix them evenly in a high-speed mixer, then add them to the granulator together, and keep the temperature at 180°C-200°C for granulation to obtain weather resistance ASA-based composites. The obtained weather-resistant ASA-based composite material and PVC are co-extruded in a screw extruder, and the processing temperature ranges from 160 to 220 ° C to form co-extruded plastic products, such as doors and windows.

Abstract

The invention relates to a weather-resistance ASA-based composite material, a co-extruded plastic product and a plastic product. The composite material comprises the following components in percentage by mass: 20%-84% of an acrylonitrile-styrene copolymer, 10%-70% of an acrylonitrile-acrylic-styrene copolymer, 5%-30% of acrylic resin, and 1%-10% of an aid. The composite material comprises the acrylonitrile-styrene copolymer, the core-shell-structured acrylonitrile-acrylic-styrene copolymer, and acrylic resin; by virtue of the core-shell-structured acrylonitrile-acrylic-styrene copolymer, the composite material is endowed with excellent weather resistance; the acrylonitrile-styrene copolymer has high temperature resistance, excellent glossiness and chemical medium resistance and excellent hardness, rigidity and dimensional stability; by virtue of acrylic resin, good intermiscibility between the core-shell-structured acrylonitrile-acrylic-styrene copolymer and the acrylonitrile-styrene copolymer is achieved, thereby being beneficial to the machining, manufacturing and forming of the composite material.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a weather-resistant ASA-based composite material, co-extruded plastic products and plastic products. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, polymer materials are more and more used in daily life, for example, various plastic products for life, auto parts, electrical casings and other fields. Especially for some plastic products exposed to the outside for a long time, on the one hand, it requires a smooth appearance, and on the other hand, it requires high mechanical strength, impact resistance and weather resistance. [0003] At present, in order to improve the mechanical strength of plastic products, the co-extrusion molding process is used to form plastics and other hard materials together. Alloy-like polymer composites are formed. For example, currently wide...
