Abstract

The invention relates to a gas rib suitable for an inflatable tent, and in particular, relates to a high-pressure low-leakage-rate gas rib. The gas rib comprises a gas barrier layer, a fabric layer and an outer protective layer, the surface of the gas barrier layer is coated with an adhesive to be bonded with the fabric layer, and the fabric layer is uniformly coated with the outer protective layer. Fabric of the fabric layer is deformable high-strength fabric, and fabric yarn is at least one of Kevlar continuous fibers, high-strength polyester continuous fibers or high-strength nylon continuous fibers. The gas barrier layer is made of at least one of polyurethane resin or a film, ethylene propylene diene monomer and nitrile rubber. The outer protective layer is made of at least one of polyurethane resin, polyethylene resin, acrylic resin, polyurea resin and liquid silicone rubber resin. The bursting pressure is effectively improved, the gas leakage rate of the gas rib is effectively reduced, and the gas rib forming process is simple, high in efficiency and suitable for mechanical and automatic production.

Description

technical field [0001] The invention relates to an air rib suitable for an inflatable tent, in particular to an air rib with high pressure and low leakage rate. Background technique [0002] Inflatable tents are widely used in personal activities (including travel, outdoor activities, etc.), commercial activities (including exhibitions, trade events, advertising campaigns and amusement parks) because of their unique advantages such as small folding size, light weight, convenient transportation, low cost, and good mobility. etc.), military activities (including military training, exercises and camps, etc.) and medical assistance (including emergency hospitals, epidemic isolation and disaster relief areas, etc.) and other fields have a wide range of uses. The air rib is the frame unit of the inflatable tent, which uses the characteristics of gas pressure to expand to form a structure with a certain rigidity, which is used to support the tarpaulin and form a temporary structure...
