Description

technical field [0001] The invention relates to an automobile safety airbag material and a preparation method thereof. Background technique [0002] Existing safety air bag system is a kind of protection system of passive safety (see automobile safety performance), and it is used in cooperation with seat safety belt, can provide effective anti-collision protection for occupants. In a car collision, car airbags can reduce the head injury rate by 25% and the face injury rate by about 80%. It is mainly composed of airbag sensors, anti-collision airbags and electronic control devices. The anti-collision airbag device on the driver's side is installed in the steering wheel; the anti-collision airbag device on the passenger side is generally installed on the instrument panel. The airbag sensors are respectively installed on the left, right and middle of the cab partition; the airbag sensor and airbag system in the middle are installed together with the electronic control device....
