Abstract

The invention relates fire retardant antistatic plastic false top wire for coal mine, characterized in that it uses plastics as raw material, adds certain amount of fire retardant chemical, antistatic agent and conductive charcoal black according to the proportion as follows: plastics raw material 85-90%, fire retardant chemical 5-7%, antistatic agent 1-2%, and conductive charcoal black 4-6%, mixes them to extrude and mold once. The advantages of the products include fire-retardant, antistatic corrosion resistance, acid base resistance, high mechanical strength, primary product molding, etc.

Description

(1) Technical field: [0001] The invention relates to a safety article for underground coal mines, in particular to a flame-retardant and antistatic plastic false roof net for underground coal mines. (two) background technology: [0002] Plastic false roof nets for underground coal mines are safety products for underground coal mines. The main raw material of this product is high-density polyethylene (HDPE) or polypropylene (PP), and this material is easy to burn when heated and exposed to fire. Therefore, it is flame-retardant and antistatic. It is an extremely unresolved safety problem to improve coal mine underground supplies. At the same time, the previous plastic false roof nets for downhole are generally made by hand, which is labor-intensive and unstable in quality. (3) Contents of the invention: [0003] The purpose of the present invention is to design a flame retardant and antistatic plastic false roof net for underground coal mines. By adding a certain amount of...
