Abstract

The invention discloses a heat-resisting PVC (polyvinyl chloride)-sheathed control cable. A sheath of the cable comprises components of raw materials in parts by weight as follows: 100 parts of polyvinyl chloride, 10-20 parts of nylon, 2-5 parts of maleic anhydride grafted polyphenyl ether, 0.1-0.5 parts of pentaerythritol stearate, 5-15 parts of dibutyl phthalate, 0.2-1 part of stearic acid, 1-8 parts of isopropyl phenyl diphenyl phosphate, 2-8 parts of nano-titanium dioxide, 10-18 parts of nano calcium carbonate, 3-10 parts of maleic acid modified hydrotalcite, 5-15 parts of modified carbon nano tubes, 3-10 parts of polyacrylonitrile fiber, 0.1-0.5 parts of lanthanum diethyldithiocarbamate, 0.1-1.5 parts of calcium adipate, 0.1-0.8 parts of glyzinc, 0.2-0.5 parts of beta-diketone, 2-3.5 parts of acrylate copolymers and 0.5-2 parts of an antioxidant. The sheath of the heat-resisting PVC-sheathed control cable has high strength, and the cable has good heat resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of control cables, in particular to a heat-resistant polyvinyl chloride sheathed control cable. Background technique [0002] Polyvinyl chloride has the advantages of low price, good flame retardancy, simple processing equipment and process, wide adjustable range of hardness, good electrical insulation, oil resistance and chemical reagent resistance, etc. It can be made by adding various additives and using various molding methods. Products with different properties and a wide range of uses are widely used in insulation and sheath materials for wires and cables. However, general-purpose polyvinyl chloride materials have poor thermal stability, and are prone to self-catalyzed dehydrochlorination reactions triggered by active sites during processing, forming conjugated polyene chains, and then undergoing reactions such as chain scission and crosslinking to change color and degrade , resulting in deterioration...
