Problems solved by technology

However, these commonly used plasticizers are not compatible with resins and are easy to precipitate. Compared with ordinary plasticizers, they have a more serious impact on flame retardancy.
In the prior art, flame retardants such as antimony trioxide and zinc borate are added to improve the flame retardancy of cable products, and the greater the amount of flame retardant added, the worse the low temperature impact resistance of the cable

Abstract

The invention discloses an anti-damage low-temperature-resistant cable material, which is prepared from the following raw materials by weight: 90-110 parts of a PVC resin, 0.1-0.3 part of nanometer aluminum oxide, 15-20 parts of glass fiber, 0.5-1 part of stearic acid, 2-6 parts of white carbon black, 2-3 parts of a plasticizer, 10-12 parts of a compatilizer and 3-4 parts of a stabilizer. According to the invention, the PVC resin is used as the base material, the proper functional raw material addition ingredients are added, and in the processing process, the proper compounding is generated through cross-linking and filling effects, so that the advantages can be made up, the whole material has excellent properties of damage resistance, wear resistance, oil resistance, low temperature resistance, high tensile strength, tear resistance and the like; and the preparation process is simple, can be adjusted on existing processing equipment, is easy to operate, and can meet the requirements of large-scale production of factories.

Description

technical field [0001] The invention belongs to the technical field of cable materials, and in particular relates to a damage-resistant and low-temperature resistant cable material. Background technique [0002] With the acceleration of the country's modernization process, the power transmission and data transmission industry, which is the main development direction of the country in the future, is becoming more and more important, and its application scope and number of uses are also increasing year by year. Correspondingly, its requirements for cable materials are also increasing year by year. [0003] Traditional PVC cable materials use polyvinyl chloride as the base material. Plasticizers are added to reduce the resin processing temperature and product softening point. Add stabilizers to improve product heat resistance, delay PVC degradation, and add lubricants to improve product processing performance. , to make the material easier to demould and flow, etc., a product ...
