Flexible polyvinyl chloride (PVC) soft cable material

Abstract

The invention provides a flexible polyvinyl chloride (PVC) soft cable material which is prepared from the following component raw materials: by weight, 50-60 parts of PVC resin, 20-40 parts of polyester resin, 10-20 parts of organic silicone resin, 10-15 parts of precipitated white carbon black, 5-10 parts of wollastonite powder, 4-6 parts of dolomite, 4-6 parts of bauxite, 4-6 parts of molybdenum disulfide, 3-5 parts of pentaerythritol, 0.5-1.0 part of triphenyl phosphate, 0.1-0.2 part of antioxidant 1035, 0.1-0.2 part of antioxidant 168, 0.2-0.4 part of ferrocene, 0.1-0.3 part of stearic acid amide, 0.2-0.3 part of zinc stearate, 0.1-0.3 part of calcium stearate, 0.1-0.3 part of barium stearate, 0.1-0.2 part of phenyl methyl silicone oil and 10-15 parts of a modified filler. A plastic high mixing machine is used for mixing the formula components, after plasticizing granulation by use of a plastic extruding machine, the flexible polyvinyl chloride (PVC) soft cable material has excellent elongation and a greatly improved elastic property, and under the condition of ensuring product electrical performances, the elongation and tensile strength of a finished product can be improved.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a flexible polyvinyl chloride soft cable material and a preparation method thereof. Background technique [0002] Wire and cable have the function of power transmission and information transmission, and play an important role in people's life and production. Designing and preparing low-smoke, low-toxic cable materials with excellent flame-retardant and insulating properties has become a hot spot in flame-retardant research today. 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. It has been studied that the cable material material with...
