Problems solved by technology

However, since the polyvinyl chloride used in the wire and cable industry is soft polyvinyl chloride, the degree of polymerization cannot be too high, and because it is relatively hard, it needs to be softened in order to meet the needs of wire and cable, and in order to meet the requirements of heat resistance, low temperature resistance, Migration resistance and other properties and to meet the processing requirements, a certain amount of plasticizer must also be added, which makes it unable to meet the requirements of wear resistance and oil resistance. Therefore, the use in industries such as automobile machinery and minerals that require wear resistance and oil resistance has been greatly restricted.

Description

technical field [0001] The invention relates to the field of polyvinyl chloride materials used for making wires and cables, in particular to a wear-resistant, oil-resistant and flame-retardant polyvinyl chloride wire and cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride is an excellent wire and cable insulation sheath material, light weight, translucent, shiny, not easily corroded by acid and alkali, good mechanical properties, excellent dielectric properties, and low price, so in The wire and cable industry has always occupied an important share. However, since the polyvinyl chloride used in the wire and cable industry is soft polyvinyl chloride, the degree of polymerization cannot be too high, and because it is relatively hard, it needs to be softened in order to meet the needs of wire and cable, and in order to meet the requirements of heat resistance, low temperature resistance, For properties such as migration resistance ...
