Problems solved by technology

The processing process is easy to decompose and release hydrogen chloride, resulting in discoloration and performance degradation of plastic products; the Vicat softening point of general-purpose PVC resin is only about 80°C, and the heat distortion temperature is about 70°C
At the same time, this shortcoming seriously damages the commodity image of PVC and li

Abstract

The invention discloses a novel heat-resistant PVC plastic. The novel heat-resistant PVC plastic comprises the following components in parts by weight: 50-60 parts of a PVC matrix, 40-45 parts of ternary polymerized resin, 15-20 parts of MMA modified ABS resin, 5-10 parts of EnBACO grafted maleic anhydride, 1-5 parts of 9nm calcium carbonate, 5 parts of styrene and 10 parts of acrylate. The ternary polymerized resin is MMA-St-ChMI, and the ratio of the MMA-St-ChMI is 25: 35: 40. After being treated via a titanate coupling agent, nano calcium carbonate is added in the PVC matrix for blending and filling. The EnBACO grafted maleic anhydride is a compatibilizer. The novel heat-resistant PVC plastic has the advantages of good heat resistance and long service life.

Description

technical field [0001] The invention relates to a novel heat-resistant PVC plastic. Background technique [0002] The heat resistance research of PVC is mainly affected by the structural defects of PVC itself. In terms of output, the annual output of PVC is second only to polyethylene among the four general-purpose synthetic resins: polyethylene, polyvinyl chloride, polypropylene, and polystyrene. And it has more excellent performance characteristics than other plastics, such as flame retardancy, wear resistance, chemical corrosion resistance, and low permeability of gas and water vapor. It also has comprehensive mechanical properties, product transparency, electrical insulation, heat insulation, noise reduction, and shock absorption. It is a general-purpose material with the most superior performance-price ratio. Among the many advantages, PVC has structural defects and deficiencies. PVC has poor thermal stability. Generally, PVC materials have poor heat resistance. Produ...
