Flame-retardant polyethylene cable material capable of preventing mould

Abstract

The invention provides a flame-retardant polyethylene cable material capable of preventing mould. The flame-retardant polyethylene cable material is prepared with the following components and raw materials by weight: 50-60 parts of high-density polyethylene, 30-45 parts of linear low-density polyethylene, 10-15 parts of polyester resin, 8-10 parts of organic silicon resin, 2-3 parts of simethicone, 1-2 parts of zinc oxide, 5-10 parts of wollastonite powder, 1-2 parts of barium sulfate, 5-6 parts of dolomite, 6-8 parts of attapulgite, 4-6 parts of celestite, 10-12 parts of zinc hydroxide, 10-15 parts of triammonium phosphate, 10-12 parts of tricresyl phosphate (TCP), 6-8 parts of poly(1,2-propylene glycol adipate), 1-2 parts of sophora flavescens alcohol extract, 0.5-0.6 parts of zanthoxylum oil, 1-2 parts of OBPA (10,10'-oxybisphenoxarsine) mould inhibitor, 1-1.5 parts of PVC (polyvinyl chloride) processing agent ACR-401 (acrylate plastic modifier), and 10-15 parts of modified filler. The cable wire has good antibacterial property, and the characteristics of weather resistance, low smoke, ageing resistance, flame retardation and so on.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a flame-retardant polyethylene cable material with anti-mold function. Background technique [0002] Wire and cable are indispensable and important materials in industrial and agricultural production and modern life. my country is the world's largest producer of wire and cable. The wire and cable industry occupies a very important position in my country's national economy. However, at present, the market The cable material is not resistant to high temperature and aging, and the material turns yellow and becomes brittle after the aging test. There are more and more fires caused by aging wires. How to reduce the incidence of fire and the death rate in the event of fire, low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for non-halogen and low-smoke flame-retardant po...

Problems solved by technology

Among them, the demand for non-halogen and low-smoke flame-retardant polyethylene cable materials with anti-mold function is increasing. At present, the production of non-halogen and low-smoke flame-retardant polyethylene cable materials with anti-mold function is mostly in polyolefin substrates. Add a large amount of acetylene carbon black or acetylene carbon black to achieve the flame retardant effect, however, the addition of a large amount of inorganic materials affects the physical and mechanical properties and processing of cable materials
