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 requirements of processing, 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, high and low temperature resistance, and oil resistance has been greatly restricted.

Abstract

The invention belongs to the field of wire and cable manufacturing, and discloses a temperature-resistant oil-resistant polyvinyl chloride elastomer cable material and a preparing method thereof. According to a formula, the temperature-resistant oil-resistant polyvinyl chloride elastomer cable material is prepared from, by weight, 100 parts of polyvinyl chloride, 60-90 parts of plasticizer, 5-10 parts of a stabilizer, 20-60 parts of stabilizer, 10-35 parts of a reinforcing auxiliary material and 0.4-0.8 part of a lubricating agent. The preparing method of the temperature-resistant oil-resistant polyvinyl chloride elastomer cable material includes the steps that all the raw materials are added into a high-speed mixer in order and mixed to obtain a mixed material, and the mixed material is prepared into a cured material to obtain the temperature-resistant oil-resistant polyvinyl chloride elastomer cable material. The temperature-resistant oil-resistant polyvinyl chloride elastomer cable material has high and low temperature resistance, oil resistance, abrasion resistance and flame retardance.

Description

technical field [0001] The invention belongs to the field of wire and cable preparation, and in particular relates to a temperature-resistant and oil-resistant polyvinyl chloride elastomer 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, Migration resistance and other properties and to meet the requirements of pr...
