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.

Abstract

The invention relates to a manufacturing method of a mine blow dryer, and the method comprises the following steps: manufacturing a foundation, namely weaving and expanding 1300D or 1500D ultralow contraction twisted polyster fiber filaments serving as warps and wefts by use of a braiding machine to form the gridded foundation; manufacturing a PVC (polyvinyl chloride) rolling film; and laminatinga film on the PVC rolling film and foundation, which are subjected to high temperature plasticizing, by a film laminator to obtain the mine blow dryer. The mine blow dryer manufactured by adopting the method provided by the invention has the advantages of good abrasive resistance and tear resistance, light weight, good water-proof, anti-fouling, mildew-proof, anti-flaming and anti-static effects and long service life, is ageing-resistant and can be formed singly.

Description

[0001] This patent application is a divisional application of the invention patent with the application number "200910101573.2", the application date is August 17, 2009, and the title is "A Coal Mine Air Duct and Its Manufacturing Method". technical field [0002] The invention relates to a manufacturing method of a coal mine air duct, in particular to a manufacturing method of a coal mine underground single-formed high-strength flame-retardant and antistatic integral air duct. Background technique [0003] 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 sta...
