[0028] According to the formula shown in Table 1 below, the ingredients are mixed together, stirred and mixed evenly in a high-speed mixer, and then added to the granulator together, keeping the temperature at 180°C-220°C for granulation to obtain PVC- MMA composites. The prepared PVC-MMA composite material is co-extruded with other polymers such as PC 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.

The invention relates to a PVC-MMA composite material which comprises, by mass, 26%-91% of PVC, 5%-70% of acrylic acid resin, 3%-10% of stabilizers and 0.5%-3% of auxiliaries. According to the PVC-MMA composite material, the PVC is modified through the acrylic acid resin, and the stabilizers are added; as a result, the stability, weather fastness and impact resistance of the material can be obviously improved, the PVC is easier to process, and the material can be widely applied to various PVC plates, pipes, doors, windows and the like.
Description
technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a PVC-MMA composite material 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 that have been exposed to the outside for a long time, such as door and window profile products, on the one hand, they require a smooth appearance, and on the other hand, they require high mechanical strength, impact resistance and weather resistance. [0003] PVC material is one of the most widely used plastics at present, and is usually used in products such as sheets, pipes, shoe soles, toys, doors and windows, wire sheaths, stationery, and packaging boxes. Although PVC material has g...
