Abstract

The invention relates to a halogen-free flame-retardant polyolefin cable material with softness and low-smoke performances and a method of the halogen-free flame-retardant polyolefin cable material, in particular to polyolefin particles for producing a halogen-free flame-retardant wire and cable insulating sheath with softness performance and with low-smoke performance during burning and a preparation method of the polyolefin particles. The halogen-free flame-retardant polyolefin cable material with softness and low-smoke performances is formed by mixing raw materials such as linear low-density polyethylene resin, ethylene-octylene copolymer elastomer, propylene (C3H6) based elastomer, modified resin, a halogen-free flame retardant, a flame-retardant plasticizer, an antioxidant and a lubricant and extruding by using twin-screw extrusion with six temperature sections. The cable material is used for a raw material for producing a wire and cable insulating sheath, so that the loss caused by fire disasters can be reduced during burning, and the service life is long.

Description

technical field [0001] The invention relates to a plastic particle and a preparation method thereof. Specifically, it is a polyolefin particle used to produce a halogen-free flame-retardant wire and cable insulation sheath with soft performance and low-smoke performance when burning and a preparation method thereof. Background technique [0002] It is known in the field of wire and cable production that due to the unique softness of flexible wires and cables, they are widely used in mobile electrical equipment such as electric welding, electric power, marine, mining, wind energy, and nuclear power. At present, flexible wires and cables all use soft polyvinyl chloride as the raw material for the production of insulating sheaths. Since polyvinyl chloride is a halogen-containing material, it will release a large amount of smoke and harmful gases such as toxic and corrosive hydrogen halides when it is burned in a fire, which is very polluting to the environment and easily cause...
