AI Technical Summary

Problems solved by technology

These additives can optimize certain performances of the gas-generating composition, but the addition of these additives will lead to an increase in the gas-generating temperature of the gas-generating composition and an increase in the amount of residue, or cause the combustion speed of the gas-generating composition to slow down and the combustion efficiency to become lower. Low

Abstract

The invention discloses a making method of composition with monomer, which is characterized by the following: setting the gas-generating temperature between 720 deg.c and 910 deg.c; making the slag quantity below 15%; blending one metal monomer or non-metal monomer and guanidine derivant and nitrate; removing adhesive, caoline as flame-assisting agent, acid carclazyte, silicate and metal oxide; adopting double-screw rod to squeeze and knead continuously; fitting for making gas-bag generator to protect passengers in the automobile and airplane.

Description

technical field [0001] The present invention relates to a gas-generating composition for an airbag and its preparation, in particular to a gas-generating composition containing a single substance and its preparation method. The gas-generating composition produced by combustion generates gas components to inflate and expand the airbag. A new gas-generating composition, which can be widely used in the airbag systems of automobiles and aircrafts for human body protection. Background technique [0002] At present, the airbag system for automobiles has become a standard configuration. When a collision occurs due to the high-speed operation of the automobile, the airbag bag in the automobile airbag system is quickly inflated under the action of the gas-generating composition, expands and expands, and prevents the occupants in the car from being injured due to inertia. harm. Therefore, the action time required for the air bag gas generating agent should b...
