Abstract

The invention discloses a thermoplastic flame-retardant elastomer used for glass fiber reinforcement of a cable. The thermoplastic flame-retardant elastomer comprises the following raw materials by weight: 100 parts of a matrix resin, 20 to 40 parts of a fire retardant, 30 to 40 parts of a glass fiber, 10 to 30 parts of a plasticizer, 5 to 20 parts of a compatilizer, 1 to 2 parts of a lubricant and 1 to 2 parts of an anti-oxidant, wherein the matrix resin is one selected from or a mixture of phenyl ether and polyurethane, the fire retardant is one selected from or a mixture of ammonium polyphosphate and triphenyl phosphate, the plasticizer is one selected from or a mixture of saturated straight-chain alkane oil and cycloalkane oil, the compatilizer is oligosiloxane, the lubricant is one selected from or a mixture of siloxane and erucamide, and the anti-oxidant is one selected from or a mixture of a hindered phenol anti-oxidant, a phosphite anti-oxidant and a thioester anti-oxidant. The elastomer disclosed in the invention has good thermoplastic, strong tensile ductility, great strength and a good flame retardation effect.

Description

[0001] technical field [0002] The invention relates to a flame-retardant elastic body for cables, in particular to a glass fiber-reinforced thermoplastic flame-retardant elastic body for cables. Background technique [0003] Polyolefin elastomer material has good processability and elasticity, and is very suitable as raw material for various extruded wire sheaths. However, due to the strong flammability of polyolefin elastomer materials, when a fire occurs in the surrounding environment of wires and cables made of them, the flame will quickly spread along the cable to the entire line, resulting in the spread and expansion of the flame. Therefore, flame retardant wires and cables containing flame retardants should be selected. At present, flame retardants are mainly divided into organic flame retardants and inorganic flame retardants, halogen-containing flame retardants and halogen-free flame retardants. Organic flame retardants are some flame retardants represented b...
