Mud-resistant low-smoke zero-halogen flame-retardant cross-linked polyolefin sheathed rubber material and preparation method thereof

Abstract

The invention provides a mud-resistant low-smoke zero-halogen flame-retardant cross-linked polyolefin sheathed rubber material and a preparation method thereof. The mud-resistant low-smoke zero-halogen flame-retardant cross-linked polyolefin sheathed rubber material has the advantages of being good in oil resistance, mud resistance, thermal stability and flexibility, and solves the existing technical problems. The mud-resistant low-smoke zero-halogen flame-retardant cross-linked polyolefin sheathed rubber material comprises 70-100 parts of ethylene-vinyl acetate copolymer elastomer, 0-30 parts of ethylene-propylene-diene monomer rubber, 100-160 parts of flame retardants, 0-40 parts of reinforcing agents, 1-2.5 parts of anti-aging agents and 1.5-3 parts of coupling agents. Accordingly to the technical scheme, the mud-resistant low-smoke zero-halogen flame-retardant cross-linked polyolefin sheathed rubber material and the preparation method thereof well solves the existing technical problems.

Description

technical field [0001] The invention relates to the field of chemical engineering, in particular to a mud-resistant low-smoke halogen-free flame-retardant cross-linked polyolefin sheath rubber material and a preparation method thereof. Background technique [0002] In the national "Twelfth Five-Year" development strategy plan, it is clearly proposed to promote the development of marine economy, cultivate the development of marine engineering equipment manufacturing, etc. It can be seen that the country attaches great importance to the development of marine economy, and the competition of various countries in the future will also mainly focus on marine resources. Therefore, the advanced nature of the marine engineering equipment manufacturing industry plays a very important role in the development of the marine economy, and the cables used as supporting equipment for marine engineering also play a very important role. In our country, there are very few manufacturers of cables...

AI Technical Summary

Problems solved by technology

There are few domestically produced mud-resistant sheath materials and their performance is very unstable, so this material needs to be imported from abroad, which is not only expensive but also unstable in performance

Existing researchers use ethylene-vinyl acetate copolymer (VA content less than 28%) or ethylene-butyl acrylate copolymer (butyl acrylate content less than 30%) as the base resin for radiation cross-linking mud-resistant low-smoke and halogen-free Development of flame retardant sheathing materials, but the base resin has less polar group content, so the oil resistance of the resulting material is not very satisfactory
