Abstract

The invention discloses a high-temperature-resistant soft thermoplastic low-smoke halogen-free flame-retardant polyolefin cable material, and belongs to the technical field of cable sheath or insulation high-molecular material. The high-temperature-resistant soft thermoplastic low-smoke halogen-free flame-retardant polyolefin cable material is composed of 100 parts of a matrix resin, 100 to 150 parts of inorganic fire retardant, 3 to 10 parts of a flame-retardant synergistic agent, 1.0 to 2.0 parts of a silane coupling agent, 0 to 0.1 part of a peroxide, 1 to 4 parts of a lubricant, and 2.0 to 4.0 parts of an anti-oxidant; the matrix resin is composed of, by weight, 25 to 60 parts of an ethylene copolymer, 20 to 55 parts of an alkene segmented copolymer, and 10 to 25 parts of a compatilizer. The flame resistance and softness of the high-temperature-resistant soft thermoplastic low-smoke halogen-free flame-retardant polyolefin cable material are ensured; the high-temperature-resistant soft thermoplastic low-smoke halogen-free flame-retardant polyolefin cable material prepared via blending possesses excellent heat resistance and low temperature performance; material mechanical performance is ensured; and material hardness is reduced.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials for wire and cable sheathing or insulation, and specifically relates to a high-temperature-resistant soft thermoplastic low-smoke halogen-free flame-retardant polyolefin cable material. Background technique

[0002] The thermoplastic low-smoke, halogen-free, flame-retardant polyolefin cable materials in the prior art generally use PE / EVA as the main base material, and a large amount of inorganic flame retardant is added, and the hardness exceeds 95A, which makes the obtained cable feel stiff and difficult to completely reverse. , easy to crack. A typical example is CN1796450A (a low-smoke halogen-free flame-retardant polyolefin cable compound and its preparation method).

[0003] Using ethylene-octene copolymer elastomer or ethylene-butylene copolymer elastomer can improve the flexibility of thermoplastic low-smoke halogen-free polyolefin cables, but because the melting point of the eth...
