Problems solved by technology

The existing moisture is not scraped off when the alloy-like ASA plastic is segmented, which affects the quality of the alloy-like ASA plastic. At the same time, the segment cutting efficiency of the existing segment cutting device is low, thereby reducing the The preparation efficiency of alloy ASA plastics is improved, and at the same time, the bagging operation is carried out directly without screening after slitting, thereby reducing the quality of alloy-like ASA plastics. Reduce the efficiency of bagging, but also increase the work intensity of the operator

Abstract

The invention discloses a preparation method of alloy-like ASA plastic. The method comprises the following steps: step 1, mixing 74% by mass of polycarbonate, 20% by mass of ASA, 3% by mass of a compatilizer, 3% by mass of a flexibilizer, 0.1% by mass of a main antioxidant, 0.2% by mass of an auxiliary antioxidant and 0.4% by mass of a lubricant through a high-speed mixer; step 2, melting and extruding the mixture in the step 1 into a columnar structure through a double-screw-rod extrusion device; step 3, cooling the columnar material obtained in the step 2 in a water cooling mode; and step 4, cooling the columnar material obtained in the step 3 again in an air cooling mode. According to the method, the impact resistance and the elastic deformation capacity of the plastic are obviously improved.

Description

technical field [0001] The invention relates to the technical field related to the preparation of alloy-like ASA plastics, in particular to a preparation method of alloy-like ASA plastics. Background technique [0002] Acrylonitrile-styrene-acrylic acid copolymer (ASA) belongs to the polycarbonate alloy class, which has excellent impact resistance, heat resistance and excellent weather resistance, and is widely used in automobiles, electronic products and so on. However, its strength and impact resistance are poor, so it needs to be improved. At the same time, in the existing preparation of alloy-like ASA plastics, in order to facilitate transportation and reprocessing after extrusion molding, it is often extruded into a continuous columnar structure by extrusion molding equipment, and then air-cooled and The cooling method is combined with water cooling. When the cooling is completed, the segments are cut into short rod-shaped structures, and they are filled in the packagi...
