Problems solved by technology

Due to the side reactions (dehydrochlorination, oxidation reaction) in the polymerization process, there are head-to-head unsaturated bonds, tertiary carbon atoms with chlorine, branched chains, and oxygen-containing groups, resulting in poor stability of PVC. The PVC must be heated with stabilizers, etc. additives to reduce degradation

Description

[0001] technical field [0002] The invention provides a polymer composite material, in particular relates to a polyvinyl chloride-polycarbonate composite material and a preparation method thereof, belonging to the technical field of polymer materials. [0003] Background technique [0004] At present, the annual production capacity of PVC pipes in my country is more than 2 million tons. Despite fierce competition with other polymers, PVC still dominates the global plastic pipe market. The advantage is obtained through continuous improvement and development of the processing process of PVC pipes, including the production of PVC resin and the application of innovative technologies for PVC pipes, especially the innovation of PVC pipe processing technology and technology, which has obviously improved the economy of PVC pipes and opened up new fields of application. [0005] The chemical structure of polyvinyl chloride is [CH 2 -CHCl 〕n, its main chain is connected by C-C, l...
