An auto-ignition/booster composition in accordance with the present invention includes an auto-ignition composition 17 combined with silicone. When uncured silicone is added to a mixture of the dry granulated constituents of both the auto-ignition and booster components, an extrudable or thixotropic mixture is produced. The uncured mixture may then be applied to any desired surface 21 within an associated gas generator 10 within a vehicle occupant protection system 180, for example, thereby simplifying gas generator 10 manufacture. A gas generating system 150, 200 incorporating the present composition 17 is also contemplated.

Description

This application claims the benefit of US Provisional Application 60 / 540,163, filed January 29, 2004.

BACKGROUND OF THE INVENTION Self-igniting materials in automotive airbag inflators allow devices to be deployed safely upon ignition. By including a self-igniting composition, the potential safety issues due to inflator bursting are substantially reduced.

  On the other hand, the pyrotechnic booster composition increases the operating pressure of the pressure vessel or inflator prior to ignition of the main or first gas generant. As a result, immediate ignition of the first gas generant is facilitated along with their sustained combustion.

  Thus, most inflators or gas generators for vehicle occupant protection systems include, for example, a self-igniting composition typically juxtaposed next to a separate booster composition. Upon ignition, the spontaneous ignition composition is ignited, thereby igniting the booster composition and thereby igniting the main gas generant. Therefore, the danger from ignition is substantially mitigated.

  An ongoing challenge is to continue to simplify the gas generator manufacturing process, thereby resulting in lower overall costs. Thus, combining a self-igniting composition and a booster composition into one composition would simplify the production and assembly of gas generators, such as those used in vehicle occupant protection systems.

Summary Pyrotechnic formulations include a self-igniting composition (eg, fuel and an oxidizer such as d-glucose and potassium chlorate) and a silicone that self-ignites at a specific designed temperature or temperature range. The pyrotechnic formulation further serves as a booster for pyrotechnic gas generators used as automotive gas generators or airbag inflators. Thus, the composition of the present invention can function as a spontaneous ignition pyrotechnic and as a booster charge pyrotechnic, thereby eliminating the need for two separate compositions in the inflator.

  Furthermore, the booster composition spreads the ignition of the main gas generant by flame and / or heat conduction. The event sequence for spontaneous ignition of the inflator ignites the spontaneous ignition material, then ignites the booster material, and subsequently ignites the pyrotechnic gas generant. The present invention eliminates the need for individual spontaneous ignition and booster pyrotechnics, replaces them with one single pyrotechnic component, greatly simplifies inflator design, and improves inflator performance To do.

  By integrating the autoignition compound and the booster compound into one composition, a single autoignition / booster composition is extruded onto any surface juxtaposed to the first gas generant bed, thereby Thermodynamic communication between spontaneous ignition / booster and main propellant can be provided. Thus, the design provides greater heat transfer to the first gas generant of the inflator, thereby improving the spontaneous ignition function upon ignition. The single spontaneous ignition / booster composition of the present invention further facilitates simplification of the inflator design.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention includes a spontaneous ignition component and a booster component that are combined to form a substantially uniform mixture. The spontaneous ignition component can be any known spontaneous ignition component such as a combination of d-glucose and potassium chlorate or nitrocellulose. The booster component can be formed from an amount of silicone that is about 10-30 weight percent of the total composition, combined with a spontaneous ignition component, and an oxidizing agent such as potassium perchlorate. As long as silicone is contained therein, other components of the booster component can be formed from known gas generant compositions.

  Preferred spontaneous ignition components of the present invention include fuels and oxidants that self-ignite at specific temperatures, particularly below 250 ° C.

Examples of organic acids include tartaric acid, malic acid, succinic acid, oxydiacetic acid, malonic acid, trans-glutaconic acid, adipic acid, mucoic acid, 2,2-bis (hydroxymethyl) propionic acid, citric acid, phenylmalon There are various enantiomers of acids and quinic acids. Typical enantiomers of this group include D-tartaric acid, DL-tartaric acid, meso-tartaric acid, D-glutamic acid and D-quinic acid. The organic acid preferably has a melting point in the range of about 125 to 250 ° C. and should pass a thermal aging test at 107 ° C. for 400 hours. The spontaneous ignition temperature of the fuel is preferably about 110 to 250 ° C. as measured by differential scanning calorimetry / thermogravimetric analysis (DSC / TGA).

  The component oxidizer of the autoignition component comprises a metal chlorate, preferably potassium chlorate, at about 55-85 weight percent of the autoignition composition. The metal chlorate can be selected from the group comprising alkali metal, alkaline earth metal, and transition metal metal chlorates, and mixtures thereof.

  The composition of the present invention comprises any known spontaneous ignition composition and about 10-35 weight percent silicone. When provided in a sufficient amount of oxidation, the oxidant contained in the autoignition composition, such as potassium chlorate, can function to oxidize the autoignition fuel and silicone, for example, thereby inflator Provide booster function inside. A preferred autoignition / booster composition is a granular autoignition composition, a fuel / binder formed from about 10-35 weight percent silicone of the total composition, and about 35-55% by weight of the total composition. Contains a booster oxidant (preferably potassium perchlorate). The term “silicone” as used herein is understood as its general meaning. Hawley describes silicones (organosiloxanes) as any large group of siloxane polymers based on a structure consisting of alternating silicon and oxygen atoms with various organic groups attached to silicon:


Formula I: Examples of silicones or silicones can be shown more generally as shown in Formula 2:

Formula 2: Example of silicone

Note: In the formula, “n” indicates the number of polymer groups or molecular parts containing organic groups bonded to silicon, shown in parentheses.

Benefits realized by the use of silicone in the compositions of the present invention include the following:
Booster function in spontaneous ignition composition;
Forming a compressible elastic structure when the silicone is cured, thereby facilitating positioning and retention in the inflator assembly and ensuring intimate thermal contact with the outer surface of the inflator;
A thixotropic composition that is extrudable when the silicone is uncured, thereby facilitating ease of insertion into the inflator assembly; and from spontaneous ignition input and combustion of the silicone / oxidant composition Ease of ignition of the first gas generant from relatively hot combustion temperatures.

  Exemplary silicones are those shown in US Pat. (1990) is included. Both are referenced and incorporated as part of this specification. Silicones are available from Shin-Etsu Silicones of America, Inc. (Akron, Ohio) can be provided from any known supplier. The curing and addition of silicone is preferably performed according to the manufacturer's instructions.

  A preferred autoignition / booster composition comprises, by weight of the composition, about 25% silicone, about 35% autoignition particles, and about 40% potassium perchlorate. As is known in the art, the various components of the composition of the present invention can be made into relatively smaller particle size particles by a ball mill, vibrator mill, fluid energy mill or hammer mill.

  Accordingly, the booster component of the present invention comprises silicone and, if desired, a booster oxidant. It should be appreciated that the spontaneous ignition oxidant, for example potassium chlorate, can be provided in an amount and particle size sufficient to oxidize both the spontaneous ignition component and the booster fuel component. In general, for example, many known gas generant compositions for use in vehicle occupant protection systems are used as the second booster component of the compositions of the present invention in addition to silicone and optional booster oxidizer. Can. Known gas generating compositions are described in US Pat. Nos. 5,035,757, 6,210,505, 6,287,400, 6,074,502, 5,872,329, 5,756,929 and 5,531. 941. These patents are referenced and incorporated as part of this specification. The illustrated booster gas generant has the function of increasing the pressure of the combined pressure vessel, thereby spreading the combustion of the first gas generant bed.

  In addition to silicone as the first booster fuel, the second booster fuel includes nitrogen-containing fuels, guanidines, aminoguanidines, tetrazoles, triazoles, non-metals or metal salts of tetrazoles and triazoles, and From a group of fuels, including a mixture of The booster component oxidant can be selected from non-metallic or metallic chlorates, perchlorates, nitrates, nitrites, permanganates, oxides and mixtures, if desired. The metal salts can be selected from salts with alkali metals, alkaline earth metals and transition metals, and mixtures thereof. The second booster fuel is provided at about 0-25 weight percent of the booster component. The booster oxidizer is 0-75 weight percent of the booster component. A preferred oxidant is potassium perchlorate. The use of any self-igniting composition and silicone provides the same advantages of self-ignition and booster function, as well as the manufacturing advantages described below. A spontaneous ignition composition comprising fuel and oxidant is provided at about 20-50 weight percent of the total composition, and a booster composition comprising all essential and optional components is provided at about 50-80 weight percent. The When formulating the spontaneous ignition composition of the present invention, each component is first granulated when provided as a solid. Therefore, the spontaneous ignition component can be formed by mixing granular potassium chlorate with granular saccharide and / or granular organic acid. A planetary mixer can be used to provide a substantially uniform or substantially homogeneous mixture of the various particles. It will be appreciated that the burning rate or ballistic characteristics can be tailored by iteratively determining the desired average granule size for each component. When using a second booster component, other components known for their usefulness in the autoignition / gas generant composition can also be incorporated into the autoignition component in granular form. As such, ballistic modifiers, coolants and other useful additives can be provided in known effective amounts, or in known effective weight percentages.

  The booster components can be compounded in the same way, so the pelletized gas generant containing fuel and oxidant can be granulated and then mixed as described above. . Ballistic modifiers, coolants and other useful additives can be provided in known effective amounts or in known effective weight percentages. The gas generant components of the present invention can be supplied by well-known suppliers such as Aldrich Chemical Company of Milwaukee, Wisconsin.

  Once the spontaneous ignition component is formulated, the spontaneous ignition component and booster component are mixed together to produce a substantially uniform or homogeneous extrudable, thixotropic mixture. The uncured mixture can then be applied, for example, to any desired surface in a gas generator in a vehicle occupant protection system, thereby simplifying the production of the gas generator. Once cured, the mixture forms an elastic compressible solid.

  Typical inflator assembly methods require the formation of a spontaneous ignition container within the inflator structure. Thereafter, the spontaneous ignition tablet is placed in the container and sealed or sealed with a tape-like seal. The booster composition is then placed in the vicinity of the spontaneous ignition composition, facilitating thermodynamic communication between the two compositions upon spontaneous ignition of the spontaneous ignition composition.

  In contrast, the cured booster / spontaneously ignited material pellets are placed in an inflator assembly and packed or compressed in place, thereby causing the first surface of the material to move to the outer elements of the inflator or to the inflator's Can be in intimate contact with the housing. Thus, the inflator assembly can be designed such that no additional functions or elements are required to maintain the booster / self-igniting material in place.

  The uncured, extrudable autoignition / booster mixture can be applied directly to the desired surface 21. This surface 21 is in contact with the first gas generant and is in thermodynamic communication with the outside of the inflator. The mixture can then be subsequently cured according to the manufacturer's instructions. As such, the surface area of the spontaneous ignition composition in contact with the desired surface is increased to provide a more effective interface to increase and / or customize the thermodynamic communication with the first gas generant chamber. And / or can be optimized. When compared to a typical inflator assembly, the spontaneous ignition / booster composition of the present invention provides an improved assembly method, thereby resulting in ease of assembly, and reduced manufacturing costs, further improved. Provides performance predictability.

Accordingly, in another aspect of the invention, an inflator manufacturing method and a gas generation system are provided, wherein the gas generation system includes an inflator formed from a manufacturing method that includes the following steps:
1. Combining the particulate autoignition composition with the uncured silicone to form an autoignition / booster composition wherein the silicone is provided at about 10-35% by weight of the total composition;
2. An inflator having a surface for receiving a spontaneous ignition / booster composition, the surface providing thermodynamic communication between the spontaneous ignition / booster composition and a first gas generant composition in the inflator 2. performing; Extruding a spontaneous ignition / booster composition having uncured silicone on the surface.

  Compatible with all other aspects of inflator manufacture as shown in the examples of inflators referenced and incorporated as part of this specification, as known in the art and discussed below Can be done. Thus, for example, components such as inflator housings, igniters, filters, gas generant compositions and other typical inflator components can all be manufactured, formed, supplied, and assembled by known methods. A notable benefit in the manufacturing process of the present invention is the ability to extrude a spontaneous ignition / booster composition in one step by using uncured silicone.

  In contrast, in many known manufacturing methods, the arrangement of the individual autoignition composition and the arrangement of the individual booster composition within the inflator consist of at least two separate steps. The composition must also be contained in each container or cavity. The composition of the present invention can be extruded uncured and later cured according to the instructions of the silicone manufacturer. Roughening the surface to receive the autoignition / booster composition prior to extruding the autoignition / booster composition simplifies the deposition of the autoignition composition / booster composition on the desired surface, and / Or make it easier. For example, the surface can be any known surface present in an inflator, such as a surface present for other structural reasons. Thus, an exemplary surface can be on a chamber divider in the inflator, or can be on an igniter support tube in the inflator. Other typical inflator surfaces are also compatible with the placement of the autoignition / booster composition extrudate as long as the surface provides thermodynamic communication between the autoignition / booster composition and the first gas generant composition can do.

  Compositions formulated in accordance with the present invention preferably ignite spontaneously at about 250 degrees Celsius or less, function as a booster charge, and inhibit the production of toxic gases. In essence, the composition of the present invention burns at a relatively higher temperature, thus increasing the gas pressure. Thus, less gas is required to pressurize the combustion chamber. Unlike certain known spontaneous ignition compositions, many of the compositions of the present invention withstand a standard thermal aging test at 107 degrees Celsius for an additional 400 hours.
