Description

technical field [0001] The invention relates to the technical field of heat stabilizer production, in particular to a production system and processing technology of a composite heat stabilizer for plastic steel. Background technique [0002] PVC and PE are general-purpose plastics with the largest output and consumption. The output of PVC in the world has exceeded 100 million tons, and that of my country is 17.8 million tons. Due to the poor thermal stability of PVC and the difficulty in processing, about 4% of heat stabilizers must be added during molding and processing. Our country consumes about 700,000 tons of heat stabilizers every year. [0003] Traditionally, the heat stabilizers are mainly lead salt heat stabilizers. Because lead salt stabilizers are highly toxic, bioaccumulative, and easy to generate dust, it will cause chronic problems for operators during production and use. Lead poisoning, and will cause serious environmental pollution after being discarded. W...
