Abstract

The invention discloses a high temperature resistant flexible low-smoke zero-halogen flame-retardant polyolefin compound. The material formula thereof consists of the following materials: an ethylene-vinyl acetate copolymer, a propylene-ethylene copolymer, an interfacial compatilizer, a flame retardant, an antioxidant silane coupling agent and a lubricant, wherein, the Shore A hardness of the ethylene-vinyl acetate copolymer is less than 75, the weight content of the vinyl acetate in the raw material monomer is 30 percent to 70 percent, the Shore A hardness of the propylene-ethylene copolymer is less than 90, and the Shore A hardness of the interfacial compatilizer is less than 80. The invention can meet the high temperature resistant conditions of an aging test (135 DEG C 168h), and has the advantage of low cost.

Description

technical field [0001] The invention relates to a plastic used for wires and cables, in particular to a high-temperature-resistant soft low-smoke halogen-free flame-retardant polyolefin cable material. Background technique [0002] At present, soft low-smoke halogen-free flame-retardant polyolefin cable materials have been widely used in flexible cables, household appliances wires and cables and other products as a substitute for soft polyvinyl chloride (PVC) cable materials. Most of the soft low-smoke halogen-free flame-retardant polyolefin cable materials on the market use soft ethylene-octene copolymer and ethylene-vinyl acetate as the main resin substrates, and the addition of inorganic flame retardants is mostly about 50%. The heat temperature is limited to 70°C and 90°C, and under the aging conditions of the 105°C heat resistance grade (105°C 168h), melting deformation will occur due to the low melting point of the base material. In addition, compared with conventiona...
