Sun screening anti-cracking cable material and preparation method thereof

Abstract

The invention discloses a sun screening anti-cracking cable material and a preparation method thereof, and relates to the field of cable materials. The cable material comprises following raw materialsin parts by weight: 60 to 70 parts of PVC resin, 15 to 25 parts of organic siloxane resin, 6 to 12 parts of epoxy soybean oil, 12 to 18 parts of calcined china clay, 8 to 15 parts of calcium silicate, 10 to 16 parts of calcium carbonate, 4 to 8 parts of butyl stearate, 3 to 6 parts of epoxy butyl oleate, 4 to 9 parts of triethanolamine, 2 to 5 parts of titanium triisostearoylisopropoxide, 3 to 6parts of antimonous oxide, 3 to 6 parts of molybdenum trioxide, 4 to 8 parts of nano titanium dioxide, 3 to 7 parts of nano silicon carbide, 4 to 8 parts of aluminum hydroxide, 2 to 5 parts of chlorinated paraffin, 1.5 to 4.5 parts of sodium stearate, and 2 to 5 parts of zinc borate. The cable material has stable physical and chemical properties; the flexibility of the cable material is good, thesize shrinkage is low, the heatproof performance and weatherability are good, the bending resistant performance and mechanical impact resistant performance are excellent, the production procedure canbe standardized, and massive production is easy to realize.

Description

Technical field [0001] The invention relates to the field of cable materials, in particular to a sun-resistant and crack-resistant cable material and a preparation method thereof. Background technique [0002] Plastics for wire and cable insulation and sheaths are commonly called cable materials, including rubber, plastic, nylon and other varieties. PVC cable material is currently one of the most widely used cable materials. PVC cable material is a particle prepared by kneading and extruding polyvinyl chloride as the basic resin, adding stabilizers, lubricants, and inorganic fillers. Because of the limitation of the PVC material, the PVC material is prone to cracking and fracture after being exposed to the sun for a period of time, the cable material is relatively brittle, and the bending resistance and weather resistance are poor. Summary of the invention [0003] Aiming at the problems in the prior art, the present invention provides a sun-resistant and anti-cracking cable mate...
