Description

Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 1238145 A7 B7 V. Description of the Invention (Technical Field) The present invention relates to a novel basic metal nitrate, a method for producing the same, a gas generating agent composition, a molded body thereof, and Gas generator for airbag using gas generant composition. Suitable for airbag restraint systems such as automobiles. Conventional technology As a gas generating agent for airbags of automobile passenger protection devices, a composition containing sodium azide is conventionally used. However, regardless of the toxicity to the human body [LD50 (oral administration of rats) = 27 mg / kg] or the danger during handling, it is a problem that must be addressed squarely. Therefore, a safe non-azide-based gas generating agent composition has been developed instead. Substance, that is, a gas generating agent composition containing various nitrogen-containing organic compounds. For example, U.S. Patent No. 4,900,549 discloses a composition containing a hydrogen-containing tetrazole, a triazole compound, and an oxygen-containing oxidant. U.S. Patent No. 4,3 70,18 No. 1 discloses a gas generant composition composed of a hydrogen-free bistetrazole metal salt and an oxygen-free oxidant. U.S. Patent No. 4,3 69,079 discloses a gas generating agent composed of hydrogen-free bistetrazole metal salt, and alkali metal nitrate, alkali metal nitrite, alkaline earth metal nitrate, alkaline earth metal nitrite, and mixtures thereof. Thing. U.S. Patent No. 5,542,999 discloses a gas generating agent composed of GZT, TAGN, NG (nitroguanidine), NTO and other fuels, basic copper nitrate, a catalyst for reducing toxic gases, and a coolant. Japanese Patent Kokai No. 10-7227 3 discloses a gas generating agent composed of bistetrazole metal salt, bistetrazole ammonium salt, aminotetrazole, and ammonium nitrate. However, the above-mentioned non-azide-based gas generating agent composition is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) at the burning temperature, burning speed, phase shift, and carbon monoxide and nitrogen oxide production amount. )

1238145 A7 B7 5. Description of the invention (>) There are problems with the gas generation efficiency. For example, the gas generating agent composition of the aforementioned U.S. Patent No. 4,369,079 has a high combustion temperature, and therefore a large amount of coolant is required in actual use. The composition of U.S. Patent No. 5,542,999 may be incompletely burned in a short period of time due to the low burning speed. The gas generating agent of JP-A-Hei 10-7 227 No. 3 has a shape change due to a phase shift of ammonium nitrate in the use temperature range, so that the molded body of the gas generating agent is damaged and cannot be stably burned. In addition, Japanese Patent Application Laid-Open No. 9-3283 89 discloses a gas generating composition composed of a fuel and an oxidant. The fuel has 60 to 100% by weight of a polyamine nitrate represented by the general formulae (I) to (ΠΙ). The rest are C2-C3 alkyldiamines and the oxidant is a copper compound. Since this conventional technique must use a polyamine nitrate as a fuel, effects such as improving gas yield can be obtained. Furthermore, Japanese Patent Application Laid-Open No. 1 1-343 1 92 discloses a composition for generating gas, which is composed of a fuel mixture composed of two kinds of components and an oxidant mixture composed of three or more kinds. The fuel mixture contains a guanidine compound and an impurity The cyclic organic acid is an essential component, and the oxidant mixture is composed of a transition metal oxide, basic copper nitrate and metal chlorate, ammonium perchlorate, alkali metal nitrate, alkaline earth nitrate metal, or a mixture thereof. Since this conventional technique is a combination of more than two kinds of fuels and more than three kinds of oxidants, the effect of good ignition ability and burning speed can be obtained. In addition, U.S. Patent No. 5,542,998 discloses a gas generating mixture composed of a fuel, an oxidant, and a catalyst. The oxidant is basic copper nitrate and the catalyst is a metal oxide. It is described that a coolant of any composition can be used without a slagging agent. . In addition, U.S. Patent No. 5,542,999 discloses a kind of gas. The paper size is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page).

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 1238145 A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Copper, the catalyst is a carrier-like metal or metal alloy. It is recorded that a coolant of any composition can be used without a slag-forming agent. Both of these conventional technologies must use metal catalysts, so the manufacturing cost is high. Compared with gas generators without catalysts, if you want to ensure the same gas generation efficiency, you must increase the weight. If you reduce the weight, the gas generation efficiency will be reduced. Therefore, it is urgent to reduce the weight of the gas generator, which is not practical. In addition, French Patent No. 2,772,3 No. 70 discloses a gas explosion composition 3 which is a cross-linking reducing agent selected from the group consisting of silicone resin, epoxy resin, and polyacrylic rubber, and an additive combination of a copper compound and an organic nitrogen compound. The main oxidant of the mixture of ammonium perchlorate and chlorine trapping agent is used as an essential ingredient. Due to such a composition, this conventional technique can improve ignitability and the like. Furthermore, in the non-azide gas generating agent, due to the combination of fuel and oxidant, due to the physical and chemical interactions over a long period of time, the fuel components slowly decompose, and the thermal decomposition temperature of the fuel will drop below the original design temperature. problem. When the thermal decomposition temperature of the fuel is lowered in this way, the gas generating agent is degraded over a long period of time. Therefore, there is a need for a gas generating agent which has a small fuel decomposition and has high storage stability. SUMMARY OF THE INVENTION An object of the present invention is to provide an alkali metal nitrate which can obtain a gas generator with high stability when combined with a fuel component, and a method for producing the same. Another object of the present invention is to provide a gas generating agent composition, which has high storage stability before processing and high safety during processing, and is flammable during processing (please read the precautions on the back before filling this page)

5. Description of Invention (") The solution is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The concentration of metal nitrate salts such as copper nitrate in the solution is not specified. The concentration from 1% solution to saturated copper nitrate is optional, but generally, the amount of solvent is 200 ~ 5000 for 1 mole copper nitrate and other metal nitrates. About milliliters is better. When the concentration is higher than this range, the crystals of the obtained basic copper nitrate and the like and the crystals of the metal nitrate have a tendency to deteriorate, so that the thermal stability is deteriorated. When using too much solvent, the symmetry effect cannot be obtained, and the alkali metal nitrate salt as a by-product needs to be post-processed, such as recycling, so it is not suitable. The alkali metal bicarbonates used for neutralizing metal nitrates such as copper nitrate include potassium bicarbonate, sodium bicarbonate, lithium bicarbonate, tritium bicarbonate, and bicarbonate. However, in terms of economics, sodium bicarbonate and bicarbonate are used. Potassium is preferred. These alkali metal bicarbonate salts are mass-produced industrial medicines and are industrial raw materials that are easily available at low prices in the industry. The alkali metal bicarbonate salt can be used in the form of a solid or a solution. In the solution, the solvent can be water, or a mixed solvent of water-miscible organic solvent (such as ethanol) and water. Generally used in the state of an aqueous solution. The amount of the solvent is preferably about 1 to 10 liters relative to 1 mole of the alkali metal bicarbonate. When the alkali metal bicarbonate is solid or has a concentration exceeding the above range, if the nitric acid concentration in a nitric acid metal salt solution such as copper nitrate is not reduced, adding it to a nitric acid metal salt solution such as copper nitrate will locally increase the alkali concentration Causes side reactions to form copper hydroxide, which cannot obtain basic metal nitrates such as basic copper nitrate with good reproducibility and good thermal stability.

When the alkali metal bicarbonate is lower than this range, the quality of the test metal nitrate such as basic copper nitrate cannot be improved, and the yield of the basic metal nitrate such as single basic copper nitrate decreases, which is meaningless as an industrial production method It can be said that when it exceeds this range, metal hydroxides such as copper hydroxide are mixed in basic metal nitrates such as basic copper nitrate, which is not preferable. Although there is no particular limitation on the method for mixing a metal nitrate salt such as copper nitrate and a hydrogen carbonate test metal salt, it is generally preferable to add an alkali metal salt solution of hydrogen carbonate to a metal nitrate solution such as copper nitrate. In addition, a method in which a nitrate metal salt such as copper nitrate and an alkali metal bicarbonate salt are added at about the same time as a solution adjusted in advance at a certain pH may be used. During the addition, in order to avoid the local alkali concentration rising, it can be added under stirring, and it is better to concentrate in more than one place at the addition port. The addition rate will be affected by the reaction scale, degree of agitation, concentration of aqueous solution, number of addition ports, mixing temperature, etc., and must be considered. Generally, slow addition is preferred to locally suppress the alkali concentration. The mixing temperature of copper nitrate and other metal nitrate and alkali metal bicarbonate salts is not specified. Generally, it is carried out at a temperature ranging from room temperature to 10 ° C, and it is better to perform it under heating. Maintenance time after the addition is completed, Due to the influence of mixing temperature, mixing time, etc., it cannot be said all at once, but when the mixing temperature is high, the maintenance time should be short.
