Abstract

The invention discloses an environment-friendly power sheath and a preparation method thereof. The environment-friendly power sheath is prepared from the following raw materials in parts by weight: 40-45 parts of polylactic acid, 15-25 parts of bacterial cellulose, 15-20 parts of polyvinyl alcohol, 10-20 parts of hydroxyethyl cellulose, 10-15 parts of ethylene-propylene rubber, 10-15 parts of polycarbonate, 10-15 parts of bamboo filler, 10-15 parts of starch ether, 12-15 parts of silane coupling agent, 8-10 parts of polyhydroxybutyrate, 5-10 parts of glass fibers, 5-10 parts of brominated flame retardant and 5-10 parts of chitin, 0.5 part of chromium carbide powder, 0.5 part of borax and 0.5 part of talcum powder. The power sheath disclosed by the invention is degradable, green and environment-friendly; the power sheath is resistant to acidic/basic microbial corrosion and is good in tensile and flexural strength and high in flame retardance, thereby being applicable to electric power application in severe environments; the preparation method is simple and is easy in operation.

Description

technical field [0001] The invention relates to the field of power materials, in particular to an environment-friendly power sheath tube and a preparation method thereof. Background technique [0002] The power sheath tube is a commonly used insulating and protective heat-shrinkable sleeve on cables. The main material of this type of product is PE, which is used as the heat-shrinkable inner sheath, outer sheath, and outer insulating waterproof sheath tube in cable accessories. . The main purpose of the power sheath tube is to be used as a cable sheath to protect the cable from external damage and ensure the safety of electricity use. The power sheath tube is divided into buried type and above-ground type. However, the existing power sheath pipes cannot be used in various harsh environments, including seabed, snow, saline-alkali environment and the like. It needs to have strong cold and heat resistance, not easy to be corroded and not easy to deform. It is also a big proble...
