Abstract
The invention discloses an oil-resistant cable sheath material for a silane crosslinked ship, which comprises a component A and a component B and is characterized in that: the component A comprises the following raw materials in parts by weight: 10-20 parts of ethylene-vinyl acetate copolymer, 10-20 parts of ethylene-propylene-Xin Xi ternary block copolymer, 0.5-1 part of cross-linking agent, 0.1-0.5 part of vulcanizing agent and the like; the component B comprises the following raw materials in parts by weight: 10-20 parts of ethylene-vinyl acetate copolymer, 10-20 parts of ethylene-propylene-Xin Xi ternary block copolymer, 0.5-1 part of catalyst and the like; the invention does not need irradiation crosslinking, can be naturally crosslinked and solidified at room temperature, and solves the application problem of no irradiation equipment in undeveloped areas.
Description
Technical Field
The invention relates to the technical field of cable sheath materials, in particular to an oil-resistant cable sheath material for a silane crosslinked ship.
Background
In recent years, cables used in special occasions such as ships, seafloors and locomotives are required to have low smoke, halogen-free, flame-retardant, oil-resistant and other properties. While traditional neoprene and chlorinated polyethylene have good oil resistance, a large amount of smoke and toxic gas are emitted in the combustion process, so that the smoke and toxic gas can harm human bodies, and meanwhile, the smoke and toxic gas can corrode instruments and equipment, so that the environment-friendly requirement of people is difficult to meet.
The ethylene-vinyl acetate copolymer has excellent oil resistance, and in addition, it is excellent in high temperature resistance, weather resistance (next to EPDM) and flame retardant properties. However, in order to improve the flame retardant performance, a large amount of flame retardant such as inorganic flame retardant, aluminum hydroxide, magnesium hydroxide and the like is often required to be added, so that the mechanical performance of the material is reduced, and the organic intumescent flame retardant is often composed of small molecules, so that the flame retardant can be separated out with the passage of time when being applied to other materials, and the flame retardant effect is reduced.
Disclosure of Invention
In order to solve the technical problems, the invention provides an oil-resistant cable sheath material for a silane crosslinked ship.
The aim of the invention can be achieved by the following technical scheme:
