Problems solved by technology
The air transmission under the mine generally uses the air guide tube to transport fresh air. The quality of the air guide tube is one of the important guarantees for the conveying air. The air guide tube is generally made of a coated cloth supported by a steel ring. The production process is imprecise and the production environment is not well controlled, resulting in the problems of low strength, heavy weight, rough surface and easy aging of the processed air ducts.

Embodiment Construction
[0016] A manufacturing process of a mine-used air duct coated cloth, the manufacturing process is:
[0017] a, weaving: take the polyester fiber silk and weave it into a cylindrical gray cloth with a loom;
[0018] b. Covering film: Put a layer of PVC inner film on the inner side of the cylindrical gray cloth and heat calendering. The calendering temperature is controlled between 60-80°C;
[0019] c. Sizing: the temperature of the slurry is controlled at 10-17°C, so that the slurry is evenly coated on the outside of the tubular gray cloth, and calendered;
[0020] d. Cold plasticization: transfer the calendered tubular fabric to the first heating chamber, the temperature of the first heating chamber is controlled at 80-110°C, and the heating temperature is controlled at 1-2 minutes;
[0021] e. Process plasticization: Process plasticization is carried out in the second heating chamber, the heating temperature is controlled at 140-160°C, and the heating time is controlled at 1...

The invention relates to a process for preparing coating cloth and particularly relates to a process for preparing mining air duct coating cloth. The process comprises the following steps: firstly, weaving polyester fiber yarns to cylindrical greige cloth by using a loom, sheathing the inner side of the cylindrical greige cloth with a layer of PVC (Polyvinyl Chloride) inner film, heating and carrying out press-polishing on the PVC inner film, uniformly on the outer side of the cylindrical greige cloth with coating pulp, conveying the cylindrical greige cloth to a heating chamber for heating, and preparing the coating cloth through air cooling and water cooling processes after heating the cylindrical greige cloth. The coating cloth prepared by the process provided by the invention is strong in tear resistance, cannot be punctured or scratched easily, long in service life, high in strength, small in weight, waterproof, anti-fouling and good in mildew resistance, and the adhesivity between the inner film and the woven cloth is good enough to prevent the gap ventilation condition.
Description
technical field [0001] The invention relates to a manufacturing process of a coated cloth, in particular to a manufacturing process of a coated cloth for a mine air guide tube. Background technique [0002] During the construction of passages such as mines, tunnels, subways and air-raid shelters, it is necessary to supply fresh air to the construction site deep in the passage to dilute the toxic, suffocating and explosive gases in the side-by-side passages, and ensure the quality of air flow in the passage (composition, Temperature and speed) and quantity comply with national safety and health standards, prevent various injuries and explosion accidents, and ensure the health of production personnel. The air transmission under the mine generally uses the air guide tube to transport fresh air. The quality of the air guide tube is one of the important guarantees for the conveying air. The air guide tube is generally made of a coated cloth supported by a steel ring. The manufac...
