Efficient low-smoke composite antiflaming polyvinyl chloride (PVC) cable material and preparation method thereof

Abstract

The invention discloses an efficient low-smoke composite antiflaming polyvinyl chloride (PVC) cable material and a preparation method thereof. The cable material comprises the following raw materials in parts by weight: 80-100 parts of SG-4 PVC resin, 0-20 parts of MBS resin, 10-15 parts of diisobutyl phthalate, 0.5-1 part of lead phosphite, dibasic, 2-3 parts of lead stearate, 15-20 parts of isopropylate triphenyl phosphate, 8-12 parts of chlorcosane, 5-10 parts of activated calcium carbonate, 4-8 parts of zinc stannate, 1-2 parts of a titanate coupling agent TMC-TTS, 10-15 parts of antimonous oxide, 3-5 parts of ferrocene, 2-4 parts of potassium titanate whisker, 4-8 parts of mica powder, and 3-6 parts of composite filler. According to the invention, through the mutual synergistic effect of isopropylate triphenyl phosphate, zinc stannate, antimonous oxide and ferrocene, the fire resistance and smoke abatement property of the cable material are improved, the situation that the cable material has excellent physical and mechanical properties and electrical property is ensured, and the application reliability of the PVC cable material is improved.

Description

technical field [0001] The invention relates to a polyvinyl chloride cable material and a preparation method thereof, in particular to a high-efficiency low-smoke composite flame-retardant polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is widely used as a sheath material for wires and cables due to its flame retardant, oil resistance, corona resistance, chemical corrosion resistance, good water resistance and processability. In the PVC cable material, due to processing needs, a relatively large amount of plasticizer is added, so that the chlorine content is greatly reduced, and the oxygen index is also reduced, so that there is a serious fire hazard in the use of cable products. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency low-smoke composite flame-retardant polyvinyl chloride cable material and its preparation method to improve the flame-r...
