Abstract

The invention discloses a high-speed extrusion flame-retardant PVC high-wiring-harness material and a preparation method thereof. The material comprises the following raw materials in parts by weight:100 parts of polyvinyl chloride resin, 0-10 parts of chlorinated polyethylene, 0-15 parts of a stabilizer compound, 30 to 70 parts of a non-phthalate plasticizer, 20 to 60 parts of a flame retardant,20-60 parts of an inorganic filler, 0.1 to 1.5 parts of an antioxidant, and 0.5 to 1.5 parts of a lubricant, wherein the polyvinyl chloride resin is ethylene-process PVC resin, and the polymerizationdegree of the polyvinyl chloride resin is 1280-1320. The raw materials are stirred, mixed and extruded to obtain the high-wiring-harness material, and the material is high in extrusion speed, high inflame retardant grade and low in cost.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-speed extrusion flame-retardant PVC high wire harness material and a preparation method thereof. Background technique [0002] The high-voltage wiring harness is the main body of the network of the high-voltage circuit, and there is no high-voltage circuit without the wiring harness. The wire harness refers to the contact terminal (connector) punched out of copper and the wire and cable after crimping, and the outside is re-molded with an insulator or a metal shell, etc., and is bundled with a wire harness to form a connected circuit assembly. The wire harness industry chain includes wire and cable, connectors, processing equipment, wire harness manufacturing and downstream application industries. Wire harnesses are widely used and can be used in household appliances, computers and communication equipment, and various electronic instruments and meters. [0003] Co...
