Abstract

The invention relates to a coal mine air cylinder which comprises gridding base cloth and a PVC calendered coating covered on the base cloth, wherein the PVC calendered coating is coated with antistatic agent, and the gridding base cloth is spun by taking twisting polyester fiber filament yarn as warp and weft; the PVC calendered coating comprises the components based on the parts by weight: 100 parts of SG-70 resin, 73-112 parts of plasticizer, 8-12 parts of inorganic fire retardant, 60-65 parts of inorganic filler, 0.2-1 part of anti-aging agent, 0.1 part of antiseptic, 20-25 parts of pigment and 6-12 parts of coupling agent. The coal mine air cylinder has the advantages of good abrasive resistance, tear resistance, light weight, water resistance, pollution and mould prevention, inflaming retarding, good antistatic effect, ageing resistance, long service life and single-width formation.

Description

technical field [0001] The invention relates to a coal mine air duct, in particular to a coal mine underground single-formed high-strength flame-retardant and antistatic integral air duct. Background technique [0002] At present, the overall air duct used in coal mines in my country is based on glass fiber fabric, which is processed by rubber calendering and treated with surface talcum powder. Existing air ducts for coal mines have low strength and are easy to blow open and leak air. They are not good in flame retardancy, antistatic, and soft. It needs to be spliced ​​and formed, the processing and manufacturing process is simple, and the warp and weft tearing strength is not up to standard and other defects. Contents of the invention [0003] In order to solve the problems existing in the existing air ducts for coal mines, an object of the present invention is to disclose a wind ducts for coal mines with strong wear resistance, high warp and latitude tear strength, good...
