Embodiment 1
[0017] A method for making a coal mine air duct, comprising the following steps:
[0018] (1) Production of base fabric: 1300D high-strength wear-resistant ultra-low shrinkage polyester fiber filament is twisted on an imported twisting machine as the warp thread, and 1300D high-strength wear-resistant ultra-low shrinkage polyester fiber filament is used for weft. Twisted on a twisting machine, the density of the warp is 51 per 10 cm, and the density of the weft is 47 per 10 cm. It is woven and expanded by an imported weaving machine to form a grid-like base fabric with a length of 2,000 meters and a width of 3 meters.
[0019] (2) Production of PVC calendered film: PVC calendered film is made by weight including the following components: 100 parts of SG-70 resin, 47 parts of phthalic plasticizer, 15 parts of phosphate triester plasticizer, cationic 10 parts of plasticizer, 15 parts of cold-resistant plasticizer, 2.5 parts of epoxy plasticizer, 8 parts of inorganic flame retard...
Embodiment 2
[0023] A kind of manufacturing method of air duct for coal mine, except polyester fiber filament grid base cloth and PVC calendering film formula, other manufacturing methods are all the same as embodiment 1.
[0024] The polyester fiber filament mesh base fabric is woven with 1500D ultra-low shrinkage twisted polyester fiber filament as warp and weft. PVC calendered film is made by weight including the following components: 100 parts of SG-70 resin, 45 parts of phthalic plasticizer, 10 parts of phosphate triester plasticizer, 8 parts of cationic plasticizer, cold-resistant plasticizer 8 parts of epoxy plasticizer, 8 parts of inorganic flame retardant, 60 parts of inorganic filler, 0.2 part of anti-aging agent, 0.1 part of antibacterial and antifungal agent, 20 parts of coloring material, 6 parts of coupling agent.
Embodiment 3
[0026]A kind of manufacturing method of air duct for coal mine, other manufacturing methods are all the same as embodiment 1 except PVC calendering film formula. The PVC calendered film is made of the following components by weight: 100 parts of SG-70 resin, 50 parts of phthalic plasticizer, 20 parts of phosphate triester plasticizer, 12 parts of cationic plasticizer, cold-resistant plasticizer 25 parts of epoxy plasticizer, 12 parts of inorganic flame retardant, 65 parts of inorganic filler, 1 part of anti-aging agent, 0.1 part of antibacterial and antifungal agent, 25 parts of coloring material, 12 parts of coupling agent.
[0027] The specific parameters of the ultra-low shrinkage twisted polyester fiber filament used in the present invention are shown in the table below.
[0028] Ultra Low Shrinkage:
[0029]
[0030] Twisted yarn:
[0031]
[0032] Compared with the existing rubber calendering, the air duct for coal mine produced by the manufacturing method of thi...
