New high-impact PVC composite resin debut

Recently, high-impact PVC composite resin independently researched and produced by a chemical company in Hebei has obtained national invention patents. At present, the chemical industrialized production line with an annual output of 10,000 tons of high-impact PVC composite resin has been put into production, and the production equipment of the polymerization kettle has reached 30 cubic meters. By the end of 2012, the company will also build an industrialized production line of high-impact PVC composite resin with an annual output of 50,000 tons, and the polymerization reactor will expand to 70 cubic meters.

According to Ren Yuming, Rubber And Plastic deputy general manager of the company, high-impact PVC composite resin was independently developed by Shenghua Chemical and Hebei University of Technology. They took polyacrylate latex as the base and grafted vinyl chloride monomer to form a copolymer with polyacrylate as the main chain and PVC as the branch chain. The laboratory tests, 1.5 cubic meter polymerizer production plant pilot test, 13.5 Cubic polymerization reactor industrial trial production, the performance indicators have reached the technical standards.

High-impact PVC composite resin is a new type of composite material, Titanium Dioxide which combines impact resistance, wear resistance, aging resistance, corrosion resistance, flame retardance and other Pvc Resin excellent properties. It is mainly developed for the poor impact resistance of domestic general PVC resin. For a long time, domestic PVC products have been mainly used Pvc Powder for blending methods for toughening, and there are limitations such as less variety and poor quality.

At the same time, the impact resistance and rigidity of Boric Acid Flakes PVC products can not be taken into account at the same time, and there is a strong dependence on the blending processing conditions. Some domestic large-scale PVC production enterprises have begun to increase R&D investment in the field of special and special PVC resins, and initiated high-impact high-impact PVC composite resin products, but they have not been successful.
