Low-smoke zero-halogen flame retardant polyolefin cracking resisting material

Abstract

The invention discloses a low-smoke zero-halogen flame retardant polyolefin cracking resisting material. The low-smoke zero-halogen flame retardant polyolefin cracking resisting material is mainly prepared from, by mass, 10-30% of an ethylene-vinyl acetate copolymer, 10-20% of linear low density polyethylene, 5-10% of a compatilizer, 50-70% of a flame retardant, 0.1-0.5% of an antioxidant and 0.5-1% of a lubricating agent. Due to the fact that the low-smoke zero-halogen flame retardant polyolefin cracking resisting material contains zero halogen, the harm to the environment and the human body is reduced; besides, a good mechanical property and good processability are achieved while excellent flame retardance is ensured.

Description

technical field [0001] The invention belongs to the technical field of material chemistry, and in particular relates to a low-smoke, halogen-free, flame-retardant polyolefin crack-resistant material. Background technique [0002] Low-smoke halogen-free polyolefin flame-retardant materials are mainly used for wire and cable insulation and sheathing. It is formulated from resins, flame retardants, antioxidants, lubricants, and cross-linking agents. At present, with the strengthening of people's awareness of environmental protection and safety, traditional halogen-containing materials can no longer meet people's requirements. Low-smoke and halogen-free materials have become a trend and gradually replace halogen-containing materials. In different occasions, the wire and cable materials will have some different special requirements. For example, in some places where the long-term working temperature is high, the insulation and sheath of the wire and cable must not be cracked duri...

Problems solved by technology

At present, with the strengthening of people's awareness of environmental protection and safety, traditional halogen-containing materials can no longer meet people's requirements. Low-smoke and halogen-free materials have become a trend and gradually replace halogen-containing materials.

In different occasions, the wire and cable materials will have some different special requirements. For example, in some places where the long-term working temperature is high, the insulation and sheath of the wire and cable must not be cracked during the work process. However, the traditional Low-smoke, halogen-free materials cannot meet the requirements of wires and cables in this regard, so it is necessary to develop a low-smoke, halogen-free, flame-retardant polyolefin material that is resistant to cracking
