Abstract

The invention discloses a coating material for cables and a preparation method thereof. The coating material for cables is prepared by using the following components in parts by weight: 20-30 parts of dimethacrylate triethylene glycol ester, 18-28 parts of methyl isobutyl ketone, 10-15 parts of polyacrylonitrile fiber, 8-12 parts of bis-(phenyl dimethyl siloxane) methylsiliconate, 3-8 parts of inorganic matter, 3-8 parts of maleic anhydride graft polypropylene, 2-5 parts of propylene oxide butyl ether and 0.5-1 parts of di-n-butyltin dilaurate. The invention further provides a preparation method of the coating material for cables.

Description

technical field [0001] The invention belongs to the field of coating materials, in particular to a coating material for cables and a preparation method thereof. Background technique [0002] Triethylene glycol dimethacrylate is a multifunctional light-curing special material, mainly used in resins, coatings, crosslinking agents for adhesives, plastic modification, coatings, inks, leather treatment, paper processing aids , optical materials, dental and other medical materials. [0003] Polyacrylonitrile is obtained by free radical polymerization of monomer acrylonitrile, and the acrylonitrile units in the macromolecular chain are connected in a link-to-tail manner. It is mainly used to make polyacrylonitrile fiber, polyacrylonitrile fiber, its strength is not high, and its wear resistance and fatigue resistance are also poor. The advantage of polyacrylonitrile fiber is that it has good weather resistance and sun resistance, and it can maintain 77% of its original strength a...
