Problems solved by technology

However, polyvinyl chloride has problems such as poor low-temperature impact resistance, poor flame retardancy, and poor thermal stability, which will greatly limit its application as a wire and cable material in low-temperature, high-impact and high flame-retardant applications.

Description

technical field [0001] The invention relates to a low-temperature impact-resistant modified polyvinyl chloride cable material, which belongs to the technical field of cables and cable materials. 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. The design and production of low-smoke, low-toxic cable materials with excellent flame-retardant and insulating properties has become a hot spot in flame-retardant research today. Although traditional magnesium hydroxide and aluminum hydroxide flame retardants can endow materials with good flame retardant properties, however, since the matrix resin of most cable materials is a non-polar polyolefin polymer, it is difficult to combine with polar magnesium hydroxide 1. The compatibility of aluminum hydroxide is poor, which often reduces the mechanical properties and processing properties of materials. Therefore, ...
