Abstract

The invention belongs to the technical field of plastic products, in particular to a preparation method of cross-linked cable with flame retardancy, high temperature resistance and high toughness. Thecross-linked cable with flame retardancy, high temperature resistance and high toughness includes the following substances (by weight): 100-120 parts of polyethylene composites, 5 to 10 parts of composite toughener, 10 to 12 parts of active nano-calcium carbonate powder, 10 to 12 parts of flame retardant, 2 to 3 parts of lubricant, 1 to 3 parts of color masterbatch, 1 to 2 parts of plasticizing accelerator, 3 to 4 parts of calcium zinc stabilizer. By adding polyethylene composites, composite toughener, active nano-calcium carbonate powder and plasticizing accelerator, the prepared cable has excellent low temperature performance, flame retardancy, mechanical properties, good aging resistance, amazing resilience, high toughness and strength, extremely high resistance to creep, impact and flexural fatigue, strong oil resistance and good molding quality. At the same time, the material can be recycled, and its recycling rate is very high.

Description

technical field [0001] The invention belongs to the technical field of plastic products, and in particular relates to a preparation method of a flame-retardant, high-temperature-resistant, and high-toughness cross-linked cable. Background technique [0002] Nowadays, with the development of science and technology, people have higher and higher requirements for cables, which require high temperature resistance, flame retardancy and toughness, etc. Therefore, it is very important to develop a cross-linked cable with flame retardancy, high temperature resistance and high toughness. necessary.
