In detail, it seems to provide a low-residue buffer gas-generating agent composition for an airbag, which has an airbag sleeve which is required for protecting a human skull when traveling by a vehicle or the like. H-Surgery At present, gas-based agents commonly used in cushioning airbag sleeves include inorganic azide strip compounds, to be other than sodium azide. Such a composition containing an inorganic azide compound has no particular problem in terms of its burnability, and the present condition has been provided for widespread practical use. However, sodium azide has various unpleasant properties in nature. For example, a highly toxic substance is pseudo, and at the same time, sodium sulfide is easily reacted with heavy metals such as copper and lead to form a highly sensitive compound that is likely to cause a sudden pyrophoric explosion. Therefore, such a composition is manufactured, stored, and discarded It is necessary to take special measures. Printed by the Central Labor Bureau of the Ministry of Economic Affairs and the Consumer Cooperatives to compensate for these shortcomings, and the proposal is to use non-azide gas purulent _ instead of # sodium nitride. For example, Japanese Patent Application Laid-Open No. 3-208878 discloses a composition containing a gaseous gasifying agent such as tetrazolium, triazole or its gold osmium salt and osmium osmium nitrate as a main component. Compared with the azide strip composition, this composition significantly reduces the toxic side, but there are still many pus and liquid particles formed in the exhaust gas, so its gas skull production efficiency is not very high. In the specification of tfO 95/047 1 0, a gas generating agent containing phase-stabilizing ammonium nitrate (PSAN) and aminoguanidine nitrate and other nitrogen-containing compounds is shown. In USP No. 5,545,272 and WO 96/27574, it is stated that the phase is stabilized with 7-20% by weight potassium salt, and ammonium nitrate is contained. The paper standard is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). 495496 Economy Printed by A7 B7, Consumer Cooperatives of the Ministry of Standards, Ministry of Standards 5. Description of the Invention (>) An airborne generator of guanidine mixture. Such a composition may increase the incidence of gassing during combustion at a high level. However, because the calorific value is quite large, the measured combustion temperature on Polyester exceeds 2500K, so a high concentration of C0 gas is generated. Thorium-containing compounds are generally used in ordinary combustion, because only the chemical equivalents, that is, the sulfonate, hydrogen, and other elements of the gas molecules must be generated in the combustion of the gasification agent, so the comparison of II nitrogen compounds has a fever The disadvantage of high combustion temperature. If the combustion temperature is too high, there will be arrests. Excessive amounts of C0 and Νχχ gas that exceed the allowable value for the human body. When the gas generating agent composition uses a large amount of gold compounds (such as metal vapors, etc.), the solid and liquid particles generated escape from the gas generator and directly touch the bag body, which may cause the bag skull to rupture. Yu. If it is necessary to block such particles in the gas skull generator, it is necessary to attach parts, so it is difficult to miniaturize the gas generator itself. That is, it is considered to be the most superior when the gas generation is just after combustion, if the combustion temperature is low, the amount of gas generated is large, and the amount of particles generated by the solid skeleton and liquid is small. Therefore, the conventional gas generating agent composition as described above cannot satisfy the application of the airbag sleeve. The inventors of the present invention aim to solve the above-mentioned problems through repeated intensive research results to complete the present invention. That is, the present invention pseudo-provides that it contains a gasification agent generated from a phase-stabilized ammonium nitrate (PSAN) mixture and contains nitroguanidine as an essential component, and the content of nitroguanidine in the composition is 35% by weight or less. A large amount of gas is generated by combustion, which can be used as a shock absorbing safety bag for vehicles such as automobiles. — 4. — This paper size applies to China National Standard (CNS) A4 specification (210X 297 mm) (please read the note on the back first) Please fill in this page again.)

Description of the invention (;) Use a low-residue buffer airbag gas generating agent suitable for multi-project expansion of airbags Composer. The gas generating agent composition of the present invention is compared with the existing gas generating composition, which not only reduces the amount of residue generated, but also uses the gas generating agent composition of the present invention, which can greatly reduce the number of auxiliary parts required to remove the residue. Number and quantity, which can create a way to miniaturize the gas generator. Cave No. II — The gas generating agent composition of the present invention does not generate solid residues during the combustion of ammonium nitrate, and all become non-corrosive gases. Emblem, trying to suppress the formation of solid skull residues. Compared with existing gas generators, it is possible to significantly reduce the number and number of parts with hurricanes. In the present invention, the content of nitroguanidine in the composition is set to less than 35% by weight, preferably 5 to 33% by weight. Compared with the existing composition, the combustion temperature can be reduced by about 150 to 300 κ, and Can reduce the amount of heat. Lowering the combustion temperature will help reduce the toxic C0 and HO X gases. The low combustion temperature and heat generation are also beneficial to reduce the attached parts of the gas generator. Table 1 shows the theoretical calculation results of the combustion temperature and calorific value of the composition of the present invention and the existing composition in which the nitroguanidine is blended in an amount of 35% by weight or less. In Table 1, PSAHKP 10 傺 indicates a phase formed by 90% by weight of ammonium nitrate and 10% by weight of potassium peroxyacid, and NQ indicates nitroguanidine.
