Wear-resisting flame-retardant polyvinyl chloride insulation and sheathing materials

Abstract

The invention relates to insulation materials and sheathing materials, and in particular relates to a wear-resisting flame-retardant polyvinyl chloride insulation and sheathing material. The wear-resisting flame-retardant polyvinyl chloride insulation and sheathing material comprises the following raw materials in parts by weight: 100 parts of polyvinyl chloride resin, 40 to 60 parts of plasticizer, 6 to 30 parts of wearable modifying agent, 4 to 8 parts of stabilizing agent, 4 to 32 parts of fire retardant, 10 to 40 parts of filling agent, and 0.8 to 3 part(s) of lubricating agent. The insulating and sheathing material has good wear-resisting and flame-retardant properties, high squeezing performance, high rolling performance and high flexing performance, as well as high flexibility and processability.

Description

technical field [0001] The invention relates to a sheath material made of insulating material, in particular to a wear-resistant and flame-retardant polyvinyl chloride insulation and sheath material. Background technique [0002] With the mobile small appliances in use today, the safety and durability of the wires is very important. For example, during the use of electric fans and heaters, the wires are often crushed and squeezed by their own appliances or other objects; the wires are often pulled, scraped, etc. when moving small appliances. It often fails to work normally, and even leads to electric leakage and fire. There is a greater hidden danger to the safety of consumers. [0003] Therefore, soft polyvinyl chloride plastic is required to have good physical and mechanical properties when used as insulation and sheath of wires, and in special occasions, it has high wear resistance, pinching performance, crushing performance and bending performance for wires and cables....

AI Technical Summary

Problems solved by technology

[0008] The prior art disclosed above only mentions the modified material of polyvinyl chloride. Although the wear resistance has been improved to a certain extent, it cannot meet the latest wear-resistant standard of UL62 in February 2011. The wear resistance of the finished products cannot meet the requirements for use

In addition, the content of flame retardant and lubricant in the prior art disclosed above is small, the flame retardancy of the product is poor, and the product processing is difficult; the production cost is high, and the comprehensive performance of the product is poor.
