Abstract

The invention relates to an LLDPE and TPE composite cable material and a preparation method thereof. The LLDPE and TPE composite cable material is prepared from the following components in parts by weight: 80-100 parts of low-density polyethylene, 20-30 parts of thermoplastic elastomer, 10-20 parts of polyphenylene oxide resin, 3-5 parts of ethyl methacrylate, 3-5 parts of epoxidized soybean oil,10-15 parts of pentaerythritol oleate, 5-8 parts of chlorinated paraffin, 3-8 parts of modified magnesia-alumina hydrotalcite, 1-2 parts of zinc borate, 8-10 parts of a smoke suppressant, 3-5 parts ofa heat stabilizer, 0.5-1.0 part of a lubricant, 8-10 parts of filler, 1-2 parts of a composite anti-oxidant, and 1-3 parts of a nano carbon material; and the composite anti-oxidant comprises the following components in parts by weight: 75 parts of an anti-oxidant 300, 15 parts of an anti-oxidant 1010, 3 parts of VE, 2 parts of rare-earth oxide and 10 parts of white carbon black. Soft thermoplastic elastomer and polyphenylene oxide resin are added into the linear low-density polyethylene to regulate components of the material, so that a three-dimensional interpenetrating grid structure is formed inside the material, and therefore, hardness of a co-mixing system can be reduced, toughness is reinforced, heat stability is improved, and comprehensive mechanical performance of a co-mixture is improved.

Description

technical field [0001] The invention relates to an LLDPE and TPE composite cable material and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] With the rapid development of the wire and cable industry, the demand for wire and cable is gradually increasing, and the application is becoming more and more extensive. Most of the cables on the market are based on polyvinyl chloride, and PVC materials have poor cold resistance. When the temperature drops, the cables harden, which will greatly affect the construction of workers and seriously reduce the laying efficiency; at the same time, in some equipment that requires reciprocating bending, PVC cable material is difficult to use for a long time because of its poor fatigue resistance; in addition, although PVC material has good flame retardancy, PVC material will cause great damage to equipment and the environment during production and use. Application publication number CN1075...
