Abstract

The invention discloses a non-crosslinked PVC (polyvinyl chloride) material which comprises, by weight, PVC resin, styrene, 3-(2-furyl) acrylic acid, ethyl cinnamate, trioctyl trimellitate, epoxidizedsoybean oil, calcium carbonate, calcium-zinc compound stabilizers, dimethyl sulfoxide, triphenyl phosphate, dimethyl acetal, cinnamoyl chloride, diethylamine, triethylamine, 2, 3-dimethyl-2, 3-diphenyl butane and dibenzoyl peroxide. The PVC resin comprises PVC resin with the homopolymerization degree of 1300 and PVC resin with the homopolymerization degree of 1500, and the weight ratio of the PVCresin is 1:1. Raw materials and the ratio thereof are reasonable, so that the non-crosslinked PVC material has excellent thermal deformation resistance and thermal aging resistance, the insulation requirement of wires and cables with the operating temperature of 100-115 DEG C and the performance requirement of sheathing materials can be met, the raw materials in the components are more uniformlyand finely mixed and dispersed, so that better compatibility and cracking resistance are acquired, the non-crosslinked PVC material is good in softness, the problem of thermal stress cracking is avoided, the non-crosslinked PVC material has good extrusion processability, flowability, tensile strength and tensile elongation, process consumption can be decreased, and manufacturing cost can be reduced.

Description

technical field [0001] The invention relates to cable materials, in particular to a non-crosslinked PVC material. Background technique [0002] Cross-linked linear low-density polyethylene, which is currently mainly used as an insulating material for cables, is a thermosetting resin that has not only excellent heat resistance, chemical resistance, etc. but also excellent electrical characteristics. And recently, crosslinked linear low density polyethylene using organic peroxides has been most widely used in the cable industry. However, since the cross-linked linear low density polyethylene resin is a thermosetting resin, it is not recyclable due to difficulty in handling, causing environmental pollution. And the cross-linking process is necessary for the process of producing cross-linked linear low-density polyethylene cables using organic peroxides, wherein in the cross-linking process, high pressure and high temperature are required, so productivity is significantly reduc...
