Abstract

The invention relates to the technical field of cable materials, in particular to an irradiation chlorosulfonated polyethylene material and a preparation process thereof, and the irradiation chlorosulfonated polyethylene material comprises the following raw materials in parts by weight: 30-50 parts of chlorosulfonated polyethylene, 50-70 parts of chlorinated polyethylene, 20-30 parts of N330 carbon black, 60-80 parts of kaolin, 10-12 parts of magnesium oxide, 8-10 parts of chlorinated paraffin, 2-3 parts of an irradiation cross-linking agent and 2-4 parts of an anti-aging agent. The irradiation chlorosulfonated polyethylene material is reasonable in raw material formula, and the irradiation-resistant sheath rubber material with excellent solvent resistance, excellent flame retardance and excellent physical and mechanical properties is obtained through the model and proportion of chlorosulfonated polyethylene and the optimization of the filler and the cross-linking agent; and the cross-linking density of the cross-linked polymer is improved through irradiation, so that the thermal stability or the heat resistance is improved, macromolecules can be cross-linked in only a few seconds through irradiation cross-linking, the production efficiency is improved by 40% or above, the energy consumption is reduced, and the cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of cable materials, in particular to an irradiated chlorosulfonated polyethylene material and a preparation process thereof. Background technique

[0002] Chlorosulfonated polyethylene is generally cross-linked by traditional steam heating and vulcanization. After the discovery that high-energy ionizing radiation can trigger polyethylene cross-linking polymerization, everyone began to study the way of radiation cross-linking. The traditional vulcanization method, on the one hand, is highly dependent on heating energy, consumes a lot of energy such as coal and oil, pollutes the environment and increases emissions, and the production is not stable enough, which easily causes more waste. In addition, the peroxide used in the formula Combined additives also require higher environmental protection requirements and bring higher costs. Through the research and development of new environmentally friendly irradiated...
