The invention belongs to the technical field of alloy materials, and discloses a high-flow flame-retardant PVC / ABS alloy material and a preparation method thereof. The material in the present invention is made by mixing ABS resin, PVC resin, flame retardant, antioxidant, lubricant, stabilizer and processing aid. After the materials are blended, they are melted, extruded and granulated to obtain a finished product. The high-flow flame-retardant PVC / ABS alloy material prepared by the invention has good flame-retardant performance, strong fluidity, good surface appearance, easy processing and molding, simple product process operation, low cost and stable quality, and can be widely used in machinery and electronics. Instruments, household appliances and construction and other fields.
Description
technical field [0001] The invention belongs to the field of materials, and in particular relates to a high-flow flame-retardant PVC / ABS alloy material and a preparation method thereof. Background technique [0002] ABS resin is copolymerized from three monomers of acrylonitrile-butadiene-styrene, which not only maintains the gloss and processing fluidity of polystyrene, but also has the impact resistance of rubber and the rigidity of acrylonitrile, which has heat resistance. It is an engineering plastic with excellent performance and wide application due to its advantages of good resistance, good dimensional stability, and easy molding and processing. The disadvantage is poor weather resistance, flammability, and higher price. PVC is based on PVC resin, mixed with various additives such as stabilizers, plasticizers, fillers, colorants and modifiers, and processed through plasticization and molding. PVC plastic has excellent properties such as good rigidity, high strength,...
