Abstract

The invention discloses a PVC / ABS alloy material and a preparation method thereof. The PVC / ABS alloy material contains the following components by weight percent: 20-80 of PVC resin, 10-70 of ABS resin, 1-6 of heat stabilizer, 2-10 of processing aid, 1-15 of compatible and impact-resistant modifier, 1-30 of heat-resistant agent, 1-3 of fire retardant and 0-8 of other aids. The invention fundamentally solves the difficulty that high using performance and high processing performance of the PVC / ABS alloy material cannot be obtained simultaneously, and improves the product fluidity, the heat resistance, the fire resistance and the like on the premise that the physical and mechanical properties are excellent. The invention creatively realizes the optimum comprehensive balance between the using performance and the processing performance of PVC resin and ABS resin, breaks through the barriers set by foreign countries in PVC alloy material production technology, firstly reaches the international advanced level in the PVC alloy material field and further comprehensively promotes the technological level of China in alloy materials.

Description

technical field [0001] The invention relates to the field of polymer alloy materials, in particular to a high-strength, high-fluidity, high-heat-resistant PVC / ABS alloy material and a preparation method thereof. Background technique [0002] At present, there are many enterprises engaged in modified PVC in China, but there are common problems such as single product, low product grade and technical content, and poor economic benefits. The backwardness of technical level seriously restricts the development of modified PVC and related industries in China. [0003] Realizing the high performance of general-purpose plastic PVC is an effective means to improve the viability and competitiveness of PVC modification industry, and PVC alloying is an effective way to high performance, among which the alloy of PVC and ABS is the most important. PVC / ABS alloy combines the advantages of both PVC and ABS. It not only maintains the inherent flame retardancy, high rigidity, and chemical resi...
