Problems solved by technology

[0006] The antistatic ability of the air duct cloth prepared by the above invention is relatively poor. After long-term use, the generated electrons are easy to gather and generate sparks, which becomes one of the safety hazards leading to explosion accidents; in addition, the tear resistance of the existing air duct cloth Not strong, easy to be torn and affect the ventilation effect under the mine

Abstract

The invention particularly relates to an anti-static rubber wind tube fabric material for a mine and a preparation method of the anti-static rubber wind tube fabric material. The anti-static rubber wind tube fabric material for the mine comprises a rubber base fabric and a conductive fiber skeleton; the conductive fiber skeleton is formed by interweaving axial conductive fibers and radial conductive fibers and is inlaid into the inner wall of the rubber base fabric; and the axial conductive fibers are interwoven with the radial conductive fibers in a contacting and connecting manner. For the anti-static rubber wind tube fabric material for the mine, by arranging the conductive fiber skeleton in the rubber base fabric, charges generated in a ventilation tube formed by the rubber base fabriccan be timely discharged through the conductive fiber skeleton, and excessive charges are avoided from gathering on the inner wall of the rubber base fabric, so that electric sparks are avoided fromgenerating, and the antistatic ability of a wind tube fabric is effectively improved; and meanwhile, the conductive fiber skeleton forms fiber reinforcing ribs on the inner wall of the rubber base fabric, and the tear resistance performance of the rubber base fabric is improved.

Description

technical field [0001] The invention belongs to the technical field of materials; in particular, it relates to an antistatic rubber air duct cloth material for mines and a preparation method thereof. Background technique [0002] The working environment under the mine is complicated, and toxic and combustible gases such as gas will be produced in the mine layer. If the ventilation is not exhausted in time, the equipment and machinery will not be able to work at all. The quality of the air duct cloth on the ventilation equipment is determined by the safety of the mine. one of the key factors. [0003] CN103665664A discloses a coating cloth for air ducts used in coal mines. It consists of PVC resin, dioctyl phthalate, cold-resistant plasticizer, lead stearate, antimony trioxide, fuel black, bisphenol A, and phenyllintriimide, and stir in the pot for 3-5 minutes. , then add antistatic agent TC-90 and stir for 4-5 minutes to form a mixture, pour the mixture into the funnel of ...
