Description

technical field

[0001] The invention relates to the field of PVC materials, in particular to a preparation method of a heat-resistant high-strength PVC cable material. Background technique

[0002] In the prior art, the cable industry usually uses PVC as the insulating pipe material on the outside of the cable, but due to its own shortcomings, the heat resistance of PVC resin is very limited, and it is very easy to age and decompose in a high temperature environment, making the halogen in the matrix PVC material Hydrogen bonds between elements and adjacent carbon atoms produce hydrogen chloride gas to detach and form carbon-carbon double bonds on the matrix polyvinyl chloride, thus greatly reducing the mechanical properties of the material, especially prone to embrittlement, cracking and thermal deformation.

[0003] On March 16, 2018, the Chinese Patent Office disclosed a patent application for a preparation method of a heat-resistant PVC pipe. The application announcement ...
