Description

A7 B7 V. Description of the Invention (1) Technical Field The present invention relates to a gas generating agent for an airbag and an inflator for an airbag. The gas generating agent for the air bag of the present invention has excellent characteristics: that is, the concentration of toxic components such as C0 in the gas generated by its combustion (hereinafter referred to as "post-explosion gas") is significantly reduced, and it is far more than the conventional stack Nitrogen-based gas generating agents have significantly higher safety. In addition, if the inflator for an air bag of the present invention is used, the CO concentration in the gas after the explosion can be further reduced. Technical background Among the increasingly high requirements for the safety of automobiles, the need for airbags is increasing dramatically. The airbag system is used to expand the nylon bag (airbag) installed on the handlebar, control panel, etc. when the car collides at a high speed. This is used to prevent passengers from colliding with various parts of the vehicle and causing death or injury. By. For the expansion of the air bag, the gas generated by the combustion or decomposition of the gas generating agent installed in the system can be used. Printed by Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page). Gas generating agents for airbags, which mainly meet the four requirements are ideal. The first requirement is that it must "have a proper burning rate". When the burning speed is slow, it cannot expand instantly, so it cannot protect passengers. The second requirement is that "low impact ignition (sensitivity to impact ignition) is low." When the impact ignitability is high, it is easy to cause an explosion or explosion in the mixing or manufacturing process. The paper size is applicable to China National Standard (CNS) A4 (210X297 mm). Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs. A7 ___B7 5. Description of the invention (2) There is a great danger in theory. The third requirement is that "gas temperature is low." The airbag is designed to allow the passenger to get out of the car and release the gas after it expands to shrink it. However, when the gas temperature is high, the passenger may be injured by fire. In addition, the function of the airbag is reduced, or a fire occurs due to the combustion of the airbag. The fourth requirement is that "low toxic components such as CO and NOx in the gas" must be required. If the toxic content is high, passengers may encounter gas poisoning when gas is released. In addition, in terms of gases generated by the combustion of organic compounds, in general, the concentration of CO and NOx is in the opposite (inverse proportion) relationship, and it is extremely difficult to reduce the concentration of both at the same time. An azide-based gas generating base using sodium azide commonly used as a gas generating base, although it shows an appropriate combustion rate and gas temperature, and most of the gas is a harmless nitrogen gas, but there is an impact fire. The disadvantage of high sex. In addition, the gas-generating base, that is, sodium azide, causes fire or emits toxic fumes after decomposition, or reacts with oxidants to generate toxic components such as sodium oxide and sodium hydroxide, so it must always be taken seriously in handling. And need safety to ensure the equipment. In addition, because sodium azide is highly toxic, leakage of sodium azide from an airbag installation vehicle dropped on a river or the sea may cause great environmental pollution. On the one hand, in Japanese Patent Application Laid-Open No. 6-32689, Japanese Patent Application Laid-Open No. 6-32690, and Japanese Patent Application Laid-Open No. 6-227884, there are disclosed the proposals made by the present inventors that use nitrogen-containing organic compounds and oxidants as active ingredients. Non-azide gas generator. The gas generating agent has: a moderate amount of gas generation, a burning rate, and a gas showing the same degree as the conventional azide-based gas generating agent. 3 This paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm) I- I _ --—II-·--*.--I-III — ^ 1 (Please read the notes on the back before filling this page) A7 B7 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs V. Invention Description (3) At the same time, the impact ignitability is low, the hazard and toxicity of the azide-based gas generating agent are extremely low, and the price is low. In addition, the concentration of toxic components such as C0 or NOx in the gas generated by the combustion of non-azide-based gas generating agents is relatively low, and it is available for practical use, but it is still expected to be further reduced. In addition, according to Japanese Patent Application Laid-Open No. 5-238867, it is proposed to use metal oxides with a specific surface area of 5 m2 / g or more (especially, oxides of atomic order 21 (Sc) ~ 30 (Zn)) for the gas generating agent. . However, the invention described in the publication relates to a gas generating agent using sodium azide as a gas generating base, and the metal oxide is merely added for the purpose of improving the combustion speed and the ignitability. Furthermore, in this publication, the metal oxides that specifically disclose the effect are only Fe203. DISCLOSURE OF THE INVENTION The inventor has worked diligently to solve the above-mentioned conventional problems. As a result, it is seen that a specific metal oxide and / or a metal having a specific physical property is added to a non-azide gas generating agent. When the oxide is used as a combustion catalyst, the non-azide gas generating agent can maintain the good characteristics of the non-azide gas generating agent, and the concentration of toxic components in the post-explosion gas (especially the concentration of both CO and NOx) is significantly reduced. It is also seen that: at least a part of the gas ejection path of the airbag inflator is loaded with an oxidant, thereby achieving—I — I Λί--Ί —rn equipment --II —7 I order; (please first Read the notes on the back and fill in this page) __4_ This paper size is applicable to China National Standard (CNS) A4 (210X297 mm) A7 printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs ___ B7 5.

Invention Description (8) The concentration of gas components is significantly reduced. Although the reason why such excellent effects can be achieved is not fully understood, according to the inventor's research, it can be inferred that, for example, azoformamide is used as a gas generating base, and carbonyl halide is used as an oxidant. In the case of nitrogen-based gas generating agents, although there is a large difference between the thermal decomposition temperature of azomethoxamine and the thermal decomposition temperature of carbonyl halide salts, when the metal oxide is added in the combustion reaction system, the carbonyl halide The thermal decomposition temperature of the acid salt decreases and approaches the thermal decomposition temperature of azomethoxamine, resulting in a smooth reaction close to the stoichiometry of the two.

Wait. Examples of the oxygen-containing tungsten compound include tungsten oxides such as ff02, ff03, and W03.H2O. Examples of the metal salt used for tungstic acid include potassium tungstate, calcium tungstate, sodium tungstate, magnesium tungstate, cobalt tungstate, nickel tungstate, and iron tungstate.

In the description of the invention (9), tungsten oxide (vi) or gold osmium salt of tungstic acid is more suitable, especially tungsten oxide (VI) or iron tungstate. The metal oxide having a BET specific surface area of 5 m2 / g or more is not particularly limited as long as it is a metal oxide other than the aforementioned molybdenum oxide and tungsten oxide as long as the specific surface area meets the requirements. 'For example, copper oxide, nickel oxide, cobalt oxide, iron oxide, chromium oxide, and magnesium oxide' are oxides of the 3rd to 4th periodic elements in the periodic table such as alumina, zinc oxide, and manganese oxide; Among them, group νίπ and group lb elements such as copper oxide, nickel oxide, and cobalt oxide are more suitable, and copper oxide is most preferable. For metal oxides having a BET specific surface area of 5 m2 / g or more, one kind may be used alone or two or more kinds may be used in combination.

Description of the invention (10) Among the three combustion catalysts, molybdenum oxide and tungsten oxide have any content with azomethoxamine and other compounds. Nitrogen organic compounds coexist for a long time, and do not substantially decompose nitrogen-containing organic compounds. Also, generally speaking, in terms of the gas generated by combustion of nitrogen-containing organic compounds, the CO concentration is opposite to the NOx concentration (inverse proportion ), In a relationship where the concentration of one side decreases when the concentration of the other side rises, Xian believes that it is extremely difficult to reduce both sides at the same time, but the molybdenum oxide and tungsten oxide have the ability to convert C0 and NOx in the explosive gas. The concentration of both sides greatly reduces the good characteristics at the same time. The particle diameters of molybdenum oxide, tungsten oxide, and metal oxide with a BET specific surface area of 5 m2 / g or more are not particularly limited, such as with the blending amount, and Matching of other ingredients The various conditions such as the ratio, the structure, shape, and capacity of the air bag can be appropriately selected from a wide range. In addition, the blending amount of these metal oxides is not particularly limited, and can be varied from a wide range according to the conditions described above. It is suitable to choose. However, in general, for 100 parts by weight of nitrogen-containing organic compounds, G.1 ~ 5G parts by weight can be blended. If the focus is on the stability of gas generation or combustion performance, the ideal blending amount is for nitrogen-containing organic compounds. Compound 100 weight part is 0.5 to 30 weight part. In addition, if other oxygen-containing molybdenum compounds that generate molybdenum (VI) by heating are used, other oxygen-containing tungsten that generates tungsten (VI) by heating is used. In the case of a compound, the amount of molybdenum (VI) oxide and tungsten (VI) oxide produced may be within the ranges specified above. In the gas generating agent for an airbag of the present invention, its performance is not impaired. Within the range, in addition to the three essential components, a combustion regulator, a detonation preventive agent, and a combustion rate adjustment catalyst may also be added.

Description of the invention (11) Combustion regulator, generally speaking For the purpose of reducing the combustion temperature or even the gas temperature, specific examples include: hydroxides such as A1; carbonates of alkali metals such as Na, K, Ca, Mg, Ba, Sr Carbonate or bicarbonate of alkaline earth metals. Among them, hydroxides, carbonates, etc. are preferred. The blending amount of the combustion regulator is not particularly limited, and can be appropriately selected from a wide range, but generally speaking, The total amount of the nitrogen organic compound and the oxidizing agent is 100 parts by weight, and it is preferable to make it not more than 50 parts by weight, and it is preferable to make it not more than 20 parts by weight. Anti-explosion agents are used to prevent the gas-generating agent from being caught by flames or to prevent the danger of detonation from being impacted during manufacturing, transportation, and storage. With the addition of anti-explosion agents, the safety of manufacturing, transportation and storage can be further improved. As the anti-explosion agent, a known one can be used. Examples include metal oxides such as earth, alumina, diatomaceous earth, and silicon dioxide, Na, K, Ca, Mg, Zn, Cu, A1, and the like. Carbonates, bicarbonates, etc. of metals. In addition, as described above, carbonates and bicarbonates of alkali metals and earth test metals also function as combustion regulators. The blending amount of the anti-explosion agent is not particularly limited and may be appropriately selected, but in general, the total amount of the nitrogen-containing organic compound and the oxidizing agent is 100 parts by weight and 5 to 30 parts by weight may be blended. The combustion speed adjustment catalyst is mainly used for adjusting the combustion speed. Examples of those used as catalysts for adjusting the combustion rate include: (a) zinc carbonate, iron chloride, aluminum oxide, titanium oxide, vanadium oxide, hafnium oxide, oxides, calcium oxide, and oxide mirrors, etc. Oxidation of 6 periodic elements 12 This paper size applies to Chinese National Standard (CNS) A4 specification (210X297 mm) —lull I hr —l · —l · I l I Order (Please read the precautions on the back before filling this page) Printed on the C7 D7 of the Consumers' Cooperatives of the Central Bureau of Standards and Quarantine of the Ministry of Economy (Except carbonates); (b) cellulose compounds of carboxymethyl cellulose, hydroxymethyl cellulose, these ethers, and microcrystalline cellulose powders; (c) soluble starch, polyvinyl alcohol, and partial alkalis thereof And other organic polymer compounds. There is no particular limitation on the particle size of the burning rate adjusting catalyst, and it can be appropriately selected and used. The combustion rate adjusting catalyst may be used alone or in combination of two or more.

Furthermore, in the present invention, various additives that have been used for this purpose in the past may be blended within a range that does not impair the good characteristics of the gas generating agent for airbags. Among the components of the gas generating agent for an airbag of the present invention described above, there is a compound which induces the decomposition of a nitrogen-containing organic compound such as azomethoxamine. Specific examples include a compound containing an alkali component such as calcium peroxide (an oxidant) or a compound which releases an alkali component after decomposition; copper oxide, chromium oxide, and manganese oxide which are combustion catalysts. Therefore, if it is desired to use such a decomposition-inducing compound as a gas generating agent for an airbag, it is preferable to apply a surface treatment to the gas-generating agent and / or the decomposition-inducing compound.

* 1T five __ Printed by the Consumers' Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs A7 B7 Description of Invention (22) Next, the inflator for the airbag of the present invention will be described. The inflator for an airbag of the present invention is characterized in that an external oxidant is placed on at least a part of a path for ejecting the post-explosion gas into the airbag. Therefore, the inflator is not particularly limited, and a well-known structure can be widely used. In the present invention, as the external oxidizing agent, a known oxidizing agent which is the same as or different from the oxidizing agent contained in the gas generating agent for an airbag of the present invention can be used. In the present invention, the part of the inflator for external oxidant carrying is not limited as long as it is a gas discharge path after the explosion outside the combustion chamber. Examples include a cooling medium, a wire mesh filter, Ceramic filters, etc. The part used for the external oxidant is not necessarily one place. The invention uses the fact that the gas generated by the combustion of the gas generating agent becomes high temperature, thermally decomposes an external oxidant, and generates oxygen to oxidize C0 in the gas, etc., thereby achieving a further reduction in the concentration of C0 . Therefore, the gas in contact with the external oxidant has a certain high temperature; specifically, the external oxidant should be placed in the coolant that the gas coming out of the combustion chamber of the inflator first contacts. This is achieved by immersing the aerator parts of the cooling medium, wire mesh filter, ceramic filter, etc. in an aqueous solution or dispersion of oxidant, or an organic solvent or dispersion. More specifically, the aqueous solution or dispersion of the oxidant, or the organic solvent or dispersion is heated to a temperature of, for example, 70 to 10G ° C, and the aerator component is impregnated therein. 23 This paper size applies the Chinese national standard (CNS ) A4 specification (21〇 × 297 mm) ni nn H4i ^^ — ^ 1 nn.: * (Please read the notes on the back before filling in this 苋) 17 A7 __B7_____ V.

As the oxidant in the oxidation accelerator for the combustion chamber, you can use any of the oxidants mentioned above. Among them, nitrate salts such as potassium nitrate and carbonyl-acid salts such as sodium chlorate are preferably used. As the gas-generating inorganic compound, a known compound that emits gas by thermal decomposition can be used, and examples thereof include sodium bicarbonate. Further, as the inactive inorganic compound, a known compound which does not undergo thermal decomposition can be widely used, and examples thereof include silicon dioxide.

Description of the Invention (39) The second diagram is a schematic cross-sectional view showing an example of the inflator of the present invention. The inflator basically comprises: a combustion chamber (1); a gas generating agent (2); an ignition part (3); an ignition charge (4); a gas ejection hole (5); a cooling medium (6); a metal Screen filter (7); and ceramic filter (8). Except that an external oxidant (not shown) is installed in the cooling medium (6), the rest are known structures. The ignition part is composed of a lead wire (9), a platinum electrode (not shown), and a sensitizer (1 G). The mechanism of gas generation is as follows. First, as soon as the lead wire (9) is energized, the platinum electrode is heated, and the heat causes the sensitizer OG) to electrically ignite, thereby igniting the ignition powder. The igniting igniter (4) causes the gas generating agent (2) to burn, thereby generating a gas. The high-temperature gas immediately after introduction is introduced into the cooling medium (6) through the gas ejection hole (5), and is subjected to cooling. At the same time, C0 in the gas is generated from an external oxidant (installed in the cooling medium (6)). The thermally decomposed oxygen is oxidized to carbon dioxide, thereby reducing the CO concentration. The cooling medium (6) passes through the wire mesh filter (7), the ceramic filter (8) and the wire mesh filter (7), thereby removing solid impurities, and is discharged from the discharge hole (9) to the air bag ( (Not shown). The external oxidant of the cooling medium (6) is installed by immersing the cooling medium (6) in a saturated aqueous solution of sodium chlorate heated to 100 ° C, and then cooling the aqueous solution to precipitate sodium chlorate. After the surface of the cooling medium (6), the cooling medium to which sodium chlorate is attached is taken out from the aqueous solution, and heated and dried to achieve it.
