Abstract

The invention relates to vinyl stabilizer system and the application that includes the following steps: mixing stearic acid and lime, heating to 150-180 degree centigrade to take reaction to form calcium stearate, mixing stearic acid with zinc oxide, heating to 130-150 degree centigrade to take reaction to form zinc stearate, mixing calcium stearate with benzoyl stearyl methane, organiotin, polhydric alcohol, white wa, SG-16 inside and outside lubricant to take compounding to form several types high efficient calcium zinc composite stabilizer. It could be used in producing PVC-U feed pipe and drain pipe, soft PVC wire, cable, etc. It lowers process temperature, improves thermal stability and ageing resistance, improves the performace of engineering plastics.

Description

technical field [0001] The invention belongs to the technical field of manufacturing methods of plastic products. Background technique [0002] Polyvinyl chloride has important uses in industry, agriculture, transportation and every aspect of people's daily life. In recent years, the development of polyvinyl chloride in my country has advanced by leaps and bounds. In 2005, the production capacity increased by more than 40%, reaching more than 9 million tons; in 2006, the production capacity will exceed 10 million tons, which can keep pace with the United States. [0003] Polyvinyl chloride is a heat-sensitive material. Under the conditions of molding processing temperature (about 130-200°C), it will degrade, change color and decompose hydrogen chloride. Therefore, during the molding process, a heat stabilizer must be added to ensure smooth production. At present, the hard polyvinyl chloride (PVC-U) water supply and drainage pipes, PVC plastic door and window profiles and P...
