Low-air-permeability one-time forming safety air bag and production technology thereof

Abstract

The invention discloses a low-air-permeability one-time forming safety air bag which comprises double cloth. The edge of the double cloth is continuously bonded together, and a cavity can be formed inthe double cloth. A moistening layer evenly covers the fiber surface of the double cloth, and the moistening layer is manufactured through a moistening layer treatment agent. The moistening layer treatment agent comprises the following components including, by weight, 0.5-10 parts of fatty alcohol and ethylene oxide condensation compounds, 0.5-10 parts of fatty alcohol polyoxyethylene ether, 0.5-10 parts of fatty alcohol glycol ether and 70-97.5 parts of water. Each of the front surface and the back surface of the moistening layer is evenly coated with a coating. The invention further discloses a production technology of the above low-air-permeability one-time forming safety air bag. The low-air-permeability one-time forming safety air bag and the production technology of the above low-air-permeability one-time forming safety air bag have the beneficial effects that on the premise that the same pressure maintaining performance is reached, 23%-31% of the coating amount can be reduced,the use amount of the chemical raw material of organic silica gel is reduced, the cost is saved, and the production process is more environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of automobile airbags, and in particular relates to a low-permeability once-formed airbag and a production process thereof. Background technique [0002] With the increasing penetration rate of automobiles, consumers' requirements for automobiles are not only satisfied with travel needs, but also pay more attention to the safety configuration of automobiles. The passive safety configuration of automobiles has attracted more and more attention from consumers. The deployment rate of one-shot airbags in automobiles is also increasing year by year. One-shot airbags are used to protect against side impacts or rollovers, so there are pressure-holding or airtight requirements for one-shot airbags. In the industry, the fabric is usually coated with silicone to make the fabric meet the required pressure retention or air tightness. The silicone coating of one-shot airbag fabric with pressure maintaining requirements...
