Anti-radiation flame-retardant cable sheath tube

Abstract

The invention discloses a radiation-proof and flame-retardant cable sheath tube, which includes a base tube and a functional layer, and the functional layer includes the following components in parts by weight: neoprene rubber 50-70; flame retardant 30-50; Diatomaceous earth 3-5; Silicon foam resin 1.2-2; Butyl acetate 1-2; Thermal insulation powder 5-30; Butyl acetate 0.02-0.05; Glass thermal insulation powder 5-8; UV absorber 30-40, The ultraviolet absorber is a chlorobenzotriazole ultraviolet absorber. The invention improves the formula and effectively improves the problem of radiation protection; adopts the glass heat insulating powder specially developed by our company to effectively solve the problem of toughness. Imported heat insulation powder is used to effectively improve the strength of the product. By adopting the method of mixing the ultraviolet absorber and the base tube functional layer masterbatch, heating and melting, and then drawing the film to form the base tube film, the problem of the color of the base tube film affecting the visual effect in the prior art is solved. At the same time, with the help of the weather resistance of the base tube film, the ultraviolet absorber is not easy to migrate, which greatly prolongs the timeliness of the anti-ultraviolet function.

Description

technical field [0001] The invention relates to a radiation-proof and flame-retardant cable sheath tube. Background technique [0002] During transportation and use, the surface of the radiation-proof flame-retardant cable sheath is susceptible to contact pollution, scratches, cracks, etc., so it is usually necessary to wrap or cover the surface with packaging materials to protect it from pollution and damage. These materials that need to be protected, such as plastics, are easily damaged by ultraviolet rays, and packaging protection materials with anti-ultraviolet functions need to be used. In addition, the existing radiation-proof flame-retardant cable sheath tubes are poor in radiation protection and cannot meet the needs of industries. . Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a radiation-proof and flame-retardant cable sheathing tube. [0004] In order to ...
