Abstract

The invention discloses a nano wind tube and a preparation method thereof. The nano wind tube is made from glass fiber and polymer composite material by the following steps: mixing, dipping, rubber refining, vulcanizing and roll-forming. The above-mentioned polymer composite material is prepared from the following components in certain parts by weight: carbon black, nano carbon black, nano zinc oxide, nano-CaCO3, propyltrimethylchlorosilance, polyvinyl chloride (PVC) paste, PVC, rubber, didutyl ester, chlorinated paraffin, antimony trioxide, aluminium hydroxide, stearic acid, hydroquinone dibenzyl ether, tetramethyl thiuram disulfide, sulfur and the like. The nano wind tube has the advantages of small resistivity, good flame-retardant performance, and can prevent environment and human body from being polluted by nano material filling process.

Description

technical field [0001] The invention relates to a mine tunnel air duct and a preparation method of the air duct. Background technique [0002] The number of deaths caused by gas in coal mines in my country accounts for more than 30% of the death toll in coal mines, and the electrostatic discharge of underground insulating materials and equipment is one of the sources of gas ignition. Whether an item is ignited by electrostatic discharge depends on the resistivity of the material. Therefore, reducing the resistivity of the material and enhancing the flame retardancy of the material are one of the key factors to prevent the death of personnel caused by the explosion of gas caused by electrostatic discharge of the material. Most of the safety air ducts in existing coal mines are made of raw materials such as rubber and plastic, and rubber and plastic are high-resistivity materials that are flammable and easy to accumulate static electricity. Usually, the surface resistivity of ...
