Abstract

The invention discloses an ultralow temperature polyvinyl chloride (PVC) modified insulating sheath cable material, belonging to the field of materials. The cable material is mainly prepared from the following raw materials in percentage by weight: 45-50% of PVC resin, 15-20% of plasticizer, 20-25% of filler, 1-3% of electrical property modifier, 9-15% of impact resistant and high and low temperature resistant modifier, 0.4-2.2% of lubricant, 1.0-2.0% of stabilizer and 0.1-0.3% of antioxidant, wherein the plasticizer is a mixture of more than two of phthalate, terephthalate or trimellitate; and the lubricant is a mixture of a composite lubricant and oxidized polyethylene wax. The invention also provides a preparation method of the cable material. The cable material provided by the invention has the advantages of low brittle temperature and good insulating property, wherein the brittle temperature can reach -35 DEG C; and simultaneously, the preparation method of the cable material is simple and is convenient for industrialized production.

Description

technical field [0001] The invention relates to the field of materials, in particular to an ultra-low temperature polyvinyl chloride modified, insulating and sheathed cable material. Background technique [0002] PVC cable material is a common cable material, and different use environments have different requirements for PVC cable material. Polyvinylchlorid (PVC), the main component is polyvinyl chloride, PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2 / 3 of the market, and soft PVC accounts for 1 / 3. Polyvinyl chloride is mainly used in the production of soft plastic products such as artificial leather, film, and wire sheaths, as well as hard plastic products such as plates, doors and windows, pipes, and valves. The embrittlement temperature of the current soft PVC cable material is only -25°C, which is far from meeting the requirements of development. In addition, according to the national standard GB / T88152002, soft polyvinyl chlo...
