Problems solved by technology

At present, flame-retardant polyethylene is widely used in ultra-high voltage flame-retardant cables and major projects, so the requirements for its anti-mold performance are also getting higher and higher, but because flame-retardant polyethylene is added on the basis of polyethylene resin So the resistance to mold and bacteria is not as strong as that of ordinary polyethylene materials. In the prior art, most flame-retardant polyethylene cable materials do not have the function of anti-mold; or the function of anti-mold is not obvious, which cannot satisfy users. Or the performance of antibacterial cable material is obviously reduced due to the type or concentration of antibacterial agent added improperly, such as the precipitation of flame retardant or antibacterial agent, the effective period of antibacterial is short, the flame retardant effect becomes worse, and the application value is low

Abstract

The invention relates to a cable material, in particular to a mould-proof flame retardant polyethylene cable material. The mould-proof flame retardant polyethylene cable material comprises 90-120 parts of high-density polyethylene resin, 60-80 parts of linear low-density polyethylene resin, 4.5-8 parts of carbon black, 20-42 parts of a flame retardant, 2-5 parts of a composite antibacterial agent,20-28 parts of zeolite and 0.2-2 parts of auxiliaries, wherein the composite antibacterial agent comprises titanium dioxide powder wrapped by polyethylene glycol and a nano silver material; and the zeolite is subjected to refining pretreatment. The composite antibacterial agent and the flame retardant are added, so that the mould-proof flame retardant polyethylene cable material has antibacterialand flame retardant effects at the same time; meanwhile, the composite antibacterial agent and the flame retardant fill the pore structures of zeolite, and the zeolite powder is interspersed in a network structure formed by the high-density polyethylene resin and the linear low-density polyethylene resin which are blended, so that the retaining effect of the flame retardant and the composite antibacterial agent is greatly improved, and loss of the composite antibacterial agent and the flame retardant is avoided.

Description

technical field [0001] The invention relates to a cable material, in particular to a mildew-resistant flame-retardant polyethylene cable material. Background technique [0002] Since entering the 21st century, many developed countries have used antibacterial plastics in the communication industry, food packaging industry, household appliances, chemical industry and daily necessities industry. Similarly, the cable industry has also expanded the demand for antibacterial cable materials. Among them, anti-mold Flame retardant polyethylene is especially in demand. At present, flame-retardant polyethylene is widely used in ultra-high voltage flame-retardant cables and major projects, so the requirements for its anti-mold performance are also getting higher and higher, but because flame-retardant polyethylene is added on the basis of polyethylene resin So the resistance to mold and bacteria is not as strong as that of ordinary polyethylene materials. In the prior art, most flame-r...
