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 getting higher and higher, but because flame-retardant polyethylene is based on polyethylene resin with flame retardants Made, so the resistance to mold and bacteria is not as strong as ordinary polyethylene materials
In the prior art, most flame-retardant polyethylene cable materials do not have anti-mold function; or the anti-mold function is not obvious, which cannot meet the needs of users; or the anti-bacterial cable material has obvious performance due to the type or concentration of anti-bacterial agent. Decrease, Ag' is easy to precipitate when exposed to water, the effective period of antibacterial is short, and the application value is low. Due to the addition of antibacterial agents, other important properties of flame-retardant polyethylene cable materials are affected and the utilization value of the cable material is reduced. Technical defects such as

Abstract

The invention relates to a fire-retardant polyethylene cable material with mould-proof function, which is characterized by comprising the following components by weight portion: 45 to 70 portions of high density polyethylene resin, 30 to 55 portions of linear low density polyethylene resin, 2.35 to 2.85 portions of carbon black, 35 to 65 portions of fire retardant, 3 to 6 portions of lubricant, 0.5 to 2 portions of antioxidant, and 1 to 2 portions of antibacterial agent. The method for preparing the fire-retardant polyethylene cable material with the mould-proof function comprises the following steps: weighing raw materials according to a formulation, mixing the materials, and performing the processes of extruding, granulating and drying the materials to prepare the mould-proof fire-retardant polyethylene cable material. The mould-proof fire-retardant polyethylene cable material can effectively inhibit the growth, the forming and the reproduction of eight types of mould fungi includingaspergillus niger, aspergillus terreus, aureobasidium pullulans which can easily grow on a cable under the condition that the original performances and the cabling process of the fire-retardant polyethylene cable material are not influenced, thus the cable is prevented from being infringed by the mould fungi, and a number of unnecessary loss and hidden hazards to the society are avoided.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a flame-retardant polyethylene cable material with anti-mold function and a preparation method thereof. Background technique [0002] Now flame-retardant polyethylene cable materials have been widely used in functional materials such as electric wires, communication cables, data cables, power cables and heat tracing cables. Health is becoming more and more important. In life, it is inevitable to come into contact with wires and data lines with bacteria and molds, which can lead to many diseases and even life-threatening. [0003] Since the beginning of the 21st century, many developed countries have used antibacterial plastics in the communication industry, food packaging industry, home appliances, chemical industry and daily necessities industry. Similarly, the cable industry has also expanded the demand for antibacterial cable materials. Among them, anti-mold...
