Problems solved by technology

PVC / ABS alloys learn from each other in terms of performance. At present, there are more flame-retardant modifications to PVC / ABS alloys in China, such as CN101899192A, a low-smoke, fire-resistant PVC / ABS alloy and its preparation method, and CN101857707A, an environmentally friendly PVC / ABS plastic alloy. Materials and preparation methods thereof, but the cold resistance of PVC, especially the low-temperature impact resistance, is poor, which limits the scope of use of PVC / ABS, and there are also researches on the patent of cold resistance of PVC alone, such as CN101967250A cold resistance, temperature resistance, flame retardant Surface migration of PVC insulation materials introduces the use of cold-resistant plasticizers to increase the cold resistance of PVC

Description

technical field [0001] The invention belongs to the technical field of polymer alloys, and relates to a polyvinyl chloride (PVC) / acrylonitrile-styrene-butadiene copolymer (ABS) alloy and a preparation method thereof. Background technique [0002] PVC is a heat-sensitive resin with high melt viscosity, narrow molding process range, unsatisfactory processing performance, and poor impact resistance, especially low-temperature impact resistance. This limits the scope of application of PVC materials. ABS resin is the abbreviation of acrylonitrile-butadiene-styrene copolymer, which has good comprehensive properties, high impact strength and surface migration in a wide temperature range. PVC / ABS alloys learn from each other in terms of performance. At present, there are more flame-retardant modifications to PVC / ABS alloys in China, such as CN101899192A, a low-smoke, fire-resistant PVC / ABS alloy and its preparation method, and CN101857707A, an environmentally friendly PVC / ABS plast...
