Power sheath pipeline and preparation method thereof

Abstract

The invention provides a power sheath pipeline and a preparation method thereof, and relates to the field of power materials. The power sheath pipeline is prepared from the following raw materials in parts by weight: barium titanate powder, aluminum nitride powder, chromium carbide powder, borax, talcum powder, calcium carbonate powder, silica gel, decabromodiphenyl ethane, stearic acid, starch ether, chitin, polycarbonate, hydroxyethyl cellulose, polyvinyl alcohol, polyvinyl chloride, chloroprene rubber, chlorosulfonated polyethylene rubber, polyamide resin, kaolin, glass fibers, nano silicon carbide, magnesium oxide, a flame retardant, a plasticizer, a compatilizer, a thermal stabilizer, a light stabilizer and a curing agent. The preparation method comprises the following steps: (1) weighting the raw materials; (2) mixing; (3) centrifuging, extruding and molding, cutting and flaring. By adopting the power sheath pipeline, the problems of an existing power sheath pipeline that properties including tensile strength, bending strength, rigidity, coefficient of thermal conductivity and flame retarding property still need to be further improved and strengthened are solved.

Description

technical field [0001] The invention belongs to the field of power materials, and in particular relates to a power sheath tube and a preparation method thereof. Background technique [0002] The power sheath tube is a heat shrinkable tube commonly used for insulation protection on cables. The main material of this type of product is PE. After two processes of irradiation crosslinking and heating expansion, it has the function of heat shrinkage, and the shrinkage ratio is 3:1. Left and right, with diameters ranging from 50-350mm, can be used as heat-shrinkable inner sheaths, outer sheaths, and outer insulating and waterproof sheath tubes 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. In the last century, sheath tubes made of metal materials were generally used to protect c...
