AI Technical Summary

Benefits of technology

This new type of plastic cable material made up of special chemical compounds called PE (poly ethylenegly) makes sure they don't be harmful for humans or animals when used on electricity lines. It prevents boring holes through pipes caused by fungi growing around them while still providing effective resistance against fading. Additionally, this material does not interfer with existing electrical equipment like switchgear cabinets because its properties are maintained even after long periods of usage without replacing any parts. Overall, these technical improvements make better quality control during manufacture more efficient and cost-effective than previous methods.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the durability and effectiveness of flammable polymer compositions that resist growth of harmful microorganisms like germs and mould during their production process. This helps prevent damage caused by these organism while maintaining good electrical conductivity and insulation quality over time.

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 including aspergillus 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.
