Abstract

The invention discloses a flame-retardant heat-resistant polyvinyl chloride material and a preparation method thereof. The flame-retardant and heat-resistant polyvinyl chloride material is prepared from the following raw materials in parts by weight: 100 parts of polyvinyl chloride resin powder, 10 to 18 parts of butadiene rubber, 5 to 10 parts of maltodextrin, 0.3 to 0.9 part of sodium diisobutylnaphthalene sulfonate, 0.1 to 0.16 part of sodium bis-2-ethylhexylthiosuccinate, 0.15 to 0.35 part of zinc borate, 0.1 to 0.2 part of an antioxidant, 0.2 to 0.5 part of methyl silicone oil and 0.4 to0.8 part of a vulcanizing agent. The preparation method of the flame-retardant heat-resistant polyvinyl chloride material comprises the following steps: S1, preparing raw materials; s2, mixing the raw materials; and S3, plasticizing and granulating the mixed raw materials. The polyvinyl chloride material provided by the invention has good mechanical properties, heat resistance, flame retardancy and processing formability, and the preparation method is simple, easy for industrial production and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant heat-resistant polyvinyl chloride material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is a polymer formed by polymerization of vinyl chloride monomer in peroxide, azo compound and other initiators, or under the action of light and heat according to the mechanism of free radical polymerization. Its biggest advantage is its superior flame retardancy, so it is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers and other fields. . However, the temperature resistance of ordinary polyvinyl chloride materials is only 60°C. Working at higher temperatures for a long time will release toxic gas hydrogen chloride, and the overall performance of the mat...
