Problems solved by technology

[0002] A large number of chlorinated polyvinyl chloride pipes are used in the transformation of power grids above 30kV in the power industry, but the sheath pipes made of chlorinated polyvinyl chloride are not only sensitive to temperature changes, but also the strength of the sheath pipes is affected by the environment or external force. It is prone to deformation and damage over time, and gradually loses its use function

Abstract

The invention discloses a chlorinated polyvinyl chloride sheath for a 30kV power cable. The chlorinated polyvinyl chloride sheath is prepared from the following raw materials in parts by weight: 40 to 50 parts of nitrile silicone rubber, 90 to 110 parts of chlorinated polyvinyl chloride, 2 to 4 parts of barium stearate, 1 to 2 parts of dioctyl sebacate, 1 to 2 parts of epoxidized soybean oil, 2 to 4 parts of chlorinated paraffin, 2 to 4 parts of polyethylene glycol, 50 to 70 parts of a filling material, 6 to 12 parts of a flexibilizer, 1 to 2 parts of maleic anhydride and 1 to 2 parts of 2-hydroxyl-4-methoxybenzophenone. The chlorinated polyvinyl chloride sheath for the 30kV power cable is extremely high in deformation resistance and tear resistance and relatively excellent in mechanical property and can bear most charges, effectively enhance the toughness and avoid the phenomenon of brittle failure.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a chlorinated polyvinyl chloride sheath for 30kV power cables. Background technique [0002] A large number of chlorinated polyvinyl chloride pipes are used in the transformation of power grids above 30kV in the power industry, but the sheath pipes made of chlorinated polyvinyl chloride are not only sensitive to temperature changes, but also the strength of the sheath pipes is affected by the environment or external force. Over time, it is prone to deformation and damage, and gradually loses its use function. Therefore, the research and development of plastic sheath tubes with good thermal stability, tear resistance and deformation resistance have attracted the attention of technical personnel in the field of material engineering. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a chlo...
