Abstract

The invention discloses a low-temperature and crack resistant chlorinated polyethylene cable material and a preparation method thereof. The cable material is prepared from, by weight, 60-80 parts of chlorinated polyethylene, 26-30 parts of low-phenyl silicone rubber, 30-40 parts of a tetrafluoroethene-perfluoromethyl vinyl ether copolymer, 8-12 parts of stearic acid, 7-9 parts of magnesium oxide, 5-8 parts of di-n-hexyl azelate, 25-35 parts of di(butylcarbitol) adipate, 5-7 parts of bis-(gamma-triethoxysilylpropyl)tetrasulfide, 6-8 parts of 2-imidazolidinethione, 1-2 parts of lauroyl peroxide, 6-8 parts of stannous chloride and 25-35 parts of silicon oxynitride. The low-phenyl silicone rubber and the tetrafluoroethene-perfluoromethyl vinyl ether copolymer added in the invention have excellent low-temperature resistance, and can be combined with the chlorinated polyethylene to form one body in order to effectively improve the low-temperature resistance of the chlorinated polyethylene cable material; and the di-n-hexyl azelate and di(butylcarbitol) adipate added in the invention enhance the cold resistance of the material, and can cooperate with the silicon oxynitride and calcium titanate nano-fibers to enhance the crack resistance of the material.

Description

technical field [0001] The invention relates to a cable material, in particular to a low-temperature-resistant and crack-resistant chlorinated polyethylene cable material and a preparation method thereof. Background technique [0002] Chlorinated polyethylene is a chlorine-containing polymer prepared by chlorination of polyethylene. It has excellent heat and oxygen aging resistance, weather resistance, ozone resistance, oil resistance, flame retardancy, corona resistance and processing performance , and has good physical and mechanical properties such as tear resistance, wear resistance and flex resistance. Chlorinated polyethylene does not use chlorofluorocarbon volatile substances that destroy the ozone layer and solvents that are toxic to the human body during the production process, and its application in the cable industry is becoming more and more extensive. Although with the continuous improvement of the material technology, the performance of the cable material has ...
