Problems solved by technology

[0003] To improve the wear resistance of PVC, resins or fillers with good wear resistance are generally added. Adding polyurethane to PVC can enhance wear resistance. Adding common fillers such as calcium carbonate and talcum powder to PVC can also improve wear resistance. However, due to the soft nature of fillers such as talcum powder, their wear-resistant modification effects are general, and cannot meet the requirements of special cables and other products.

Abstract

The invention relates to a wear-resistant flame-retardant PVC gasket comprising the components of: 85 parts of polyvinyl chloride, 3 parts of magnesium chloride, 2 parts of calcium hydroxide, 9 parts of phthalate, 2 parts of molybdenum disulfide, and 2 parts of antimony trioxide. The sealing strip further comprises 7 parts of n-decyl alcohol and 1 part of paraben. The material has good wear resistance. With a coupling treatment method with a high-hardness wear-resistance modifier, the compatibility of the material with PVC is enhanced.

Description

[0001] technical field [0002] The invention relates to a chemical product, in particular to a wear-resistant and flame-retardant PVC washer. Background technique [0003] To improve the wear resistance of PVC, resins or fillers with good wear resistance are generally added. Adding polyurethane to PVC can enhance wear resistance. Adding common fillers such as calcium carbonate and talcum powder to PVC can also improve wear resistance. However, due to the soft nature of fillers such as talcum powder, their wear-resisting modification effect is average, which cannot meet the requirements of special cables and other products. Contents of the invention [0004] The technical problem to be solved by the invention is to provide a wear-resistant and flame-retardant PVC gasket. [0005] In order to solve the above-mentioned technical problems, the wear-resistant and flame-retardant PVC gasket of the present invention comprises the following components, 85 parts of polyvinyl chlo...
