Abstract

The invention relates to a waterproof and flame-retarded PVC (polyvinyl chloride) cable material for a data cable. The material comprises the following components in part by weight: 100 parts of PVC resin, 32 to 38 parts of trioctyl trimellitate, 4 to 6 parts of stabilizer, 8 to 10 parts of fire retardant and 8 to 12 parts of waterproof modifier, wherein the waterproof modifier is prepared by cladding 2 to 3 parts of nano-barium sulfate, 4 to 7.5 parts of calcined kaolin and 2 to 3 parts of nanosilicon dioxide by using 0.3 to 0.5 parts of silane coupling agent. The material can adapt to a complex using environment and resist water for a long time, and excellent electrical insulation property, mechanical property and flame resistance are also kept.

Description

technical field [0001] The invention relates to the technical field of insulating cable materials, more specifically, the invention relates to a water-resistant and flame-retardant polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) resin is the second largest resin species in the world after polyethylene. PVC resin is widely used in the cable material industry due to its advantages of good rigidity, high strength, flame retardancy, corrosion resistance, good electrical insulation, good processing performance and low price. PVC cable materials are mainly used as sheath materials for various cables such as power cables, control cables, and communication cables. Polyvinyl chloride cable materials can basically meet the requirements of insulation and sheathing, but with the continuous expansion of the application range of wire and cable, the performance requirements for PVC cable materials are...
