Abstract

The invention discloses an unbreakable PVC cable material. The PVC cable material comprises the following raw materials: 60-70 parts of SG3 PVC resin, 18-26 parts of neoprene, 26-34 parts of styrene-butadiene rubber, 6-12 parts of a flexibilizer, 4-8 parts of a phytic acid complex, 2-4 parts of epoxidized soybean oil, 1-2 parts of stearic acid, 8-16 parts of fly ash, 14-20 parts of hollow glass microspheres, 35-45 parts of nano-montmorillonite, 2-3 parts of diethoxydimethylsilane, 20-30 parts of expanded perlite, 20-30 parts of medical stone powder, 2.5-5 parts of antioxidant and 2-4 parts oftert-butyl peroxybenzoate, wherein the phytic acid complex is prepared with the following process: mixing silk fibroin fiber, sodium alginate, aniline and water, performing heating and stirring, adding phytic acid and continuously stirring the mixture to obtain a premixed solution; mixing ammonium persulfate and a hydrochloric acid solution uniformly, dropwise adding the mixed solution to the premixed solution for stirring, adding polyethylene glycol diglycidyl ether for stirring, leaving the mixture to stand for defoaming, adding a calcium chloride aqueous solution, and performing stirring uniformly and grinding to obtain the phytic acid complex.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to an unbreakable PVC cable material. Background technique [0002] In the existing technology, PVC cable material is based on PVC resin, adding plasticizer (reducing the resin processing temperature, lowering the softening point of the product), lubricant (improving product processing performance, making the material easier to demould and flow), etc. Products that are mixed together after being extruded and plasticized by an appropriate ratio. But at present, the thermal stability of PVC cable material is poor, and it is easy to break, which needs to be further improved. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a PVC cable material that is not easy to break, has good mechanical properties, is not easy to break, has excellent thermal stability and aging resistance, and is extremely low ...
