The invention discloses an environment-friendly and flame-retardant PVC insulation material capable of withstanding a temperature of 125 DEG C and being used for an automobile cable, and a preparation method thereof. The environment-friendly and flame-retardant PVC insulation material is prepared from the following raw materials by weight: 45-65 parts of an SG-3 type PVC resin, 20-30 parts of an ACS resin, 15-25 parts of a poly alpha-methyl styrene resin, 2-3 parts of a Ca-Zn composite stabilizer, 10-15 parts of epoxidized soybean oil, 5-10 parts of dipentaerythritol diphosphonate ester, 2-4 parts of stearoyl benzoyl methane, 3-6 parts of ethylene bis-stearamide, 2-3 parts of butyl stearate, 3-5 parts of white factice, 15-25 parts of carbon black N660, 8-12 parts of aluminum ash, 5-10 parts of nano titanium nitride, 4-8 parts of melamine cyanurate, 10-15 parts of magnesium hydroxide, 5-10 parts of ammonium fluoroborate, 10-15 parts of polypropylene glycol adipate, 2-4 parts of polyoxyethylene alkyl ether acetate and 12-16 parts of modified stone powder. The cable material provided by the invention has excellent heat resistance, and can keep relatively high physical and mechanical performances and relatively good electric insulation property after working for a long time at a high temperature of 125 DEG C. Meanwhile, the material provided by the invention has good flame retardant property, has low smoke and no halogen, is safe and environment-friendly, has a long service life and can be widely applied in automobile cable products.
Description
technical field [0001] The invention relates to a 125°C environment-friendly flame-retardant PVC insulation material for automobile cables and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] In recent years, my country's automobile industry has developed rapidly, and the demand for cables will inevitably increase accordingly. At the same time, the performance requirements for cable materials are also becoming more and more stringent. At present, the automotive cable materials on the market have the disadvantage of poor high temperature resistance, which cannot meet the high temperature working environment in the car. Therefore, it is urgent to change the formula of traditional cable materials and develop an environmentally friendly flame-retardant PVC insulating material resistant to 125°C to improve the safety performance of automotive cables. Contents of the invention [0003] The purpose of the present invention is...
