Polyvinyl chloride cable material

Abstract

The invention provides a polyvinyl chloride cable material, which is prepared from the following raw materials by weight: 50-60 parts of an ethylene-vinyl acetate copolymer EVA, 10-15 parts of HDPE (high density polyethylene), 10-12 parts of epoxy acrylate, 5-10 parts of ABS resin, 5-8 parts of a compatibilizer, 1-2 parts of a 3-aminopropyl trimethoxy silane, 1-2 parts of an aluminate coupling agent DL-411, 4-6 parts of dolomite, 4-6 parts of sepiolite, 1-2 parts of beryllium oxide, 2-3 parts of zinc oxide, 6-8 parts of dibutyl phthalate, 6-8 parts of tributyl citrate, 3-4 parts of dioctyl maleate, 0.1-0.2 part of oleamide, 10-12 parts of heavy calcium, 1-2 parts of barium stearate, 0.1-0.3 part of oxidized polyethylene wax, 10-15 parts of zinc borate, 4-6 parts of molybdenum trioxide, 1-2 parts of iron oxide and 10-15 parts of a modified filler. The invention has the advantages of simple preparation method, convenient operation and reasonable formula for raw materials. The prepared cable material has the characteristics of good weathering resistance, low smoke, aging resistance and good flame retardant performance.

Description

Technical field [0001] The invention relates to the field of cable materials, in particular to a polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] Wires and cables have the function of power transmission and information transmission, and play an important role in people's life and production. The design and preparation of low-smoke, low-toxicity, and excellent flame-retardant and insulation properties at the same time has become a hot spot in flame retardant research. Although traditional magnesium hydroxide and aluminum hydroxide flame retardants can impart good flame retardant properties to the material, the matrix resin of most cable materials is non-polar polyolefin polymer, which is compatible with polar hydrogen. Magnesium oxide and aluminum hydroxide have poor compatibility, which tends to reduce the mechanical properties and processing properties of the material. It has been developed that cable materials with good flame r...

Problems solved by technology

Although the traditional magnesium hydroxide and aluminum hydroxide flame retardants can endow the material with good flame retardancy, however, since the matrix resin of most cable materials is a non-polar polyolefin polymer, the polar hydrogen The compatibility of magnesium oxide and aluminum hydroxide is poor, which often reduces the mechanical properties and processing properties of materials
