Definitions
- the invention relates to granulated gas sets and their use.
- the common method for producing gas sets for example for automotive safety, is to compress the raw materials into tablets. With these tablets, the desired burning process can be achieved. Disadvantages of this technology are the costly manufacture of the tablets and the high pressures required to achieve strength when pressing, particularly with regard to safety.
- the raw materials are usually mixed with one another dry or, if appropriate, with small amounts of pressing aids and pressed together.
- the object of the present invention is to provide novel granulated gas sets.
- the aforementioned object of the invention is achieved by granulated gas sets with nitrogen oxide-free and low-carbon monoxide fumes, which
- binders in an amount of 5 to 50% by weight
- oxidizing agents in an amount of 0 to 90% by weight
- organic, in particular nitrogen-free fuels in an amount of 0 to 75% by weight.
- the present invention relates in particular to combinations of binders, metal salts of oxidizing acids and / or organic, preferably nitrogen-free fuels for use, for example, in gas generators as pyrotechnic mixtures for producing gases.
- the gas sets are obtained by granulating the components from a solvent-containing suspension of the components by adding water.
- the gas sets defined according to the invention are characterized by nitrogen oxide-free and significantly reduced carbon monoxide fumes and a high thermal stability compared to conventional materials produced on the basis of nitrocellulose as the sole energy source. Furthermore, they are characterized by the simple manufacturing process and the associated control of the burning rate via grain size, additives and coating sets.
- the gas sets defined according to the invention are preferably based on mixtures of nitrogen-free components as energy sources and binders with proportions by weight of 5 to 50% by weight, such as cellulose acetate, cellulose acetate butyrate, cellulose acetate, nitrocellulose (here a subordinate amount in the function as binder) and polyvinyl butyral.
- Perchlorates of, for example, the alkali and alkaline earth metals, zinc peroxide, iron oxides, cerium dioxide, copper oxide, permanganates, tin dioxide and manganese dioxide can be used as oxidizing agents.
- Potassium perchlorate and zinc peroxide are preferably used in proportions by weight of 0 to 90% by weight.
- Organic nitrogen-free fuels such as terephthalic acid, fumaric acid and / or ascorbic acid can be added in parts by weight of 0 to 75% by weight.
- Aluminum oxide, zinc oxide, silicates of alkali and alkaline earth metals, clays of different compositions, cement, gypsum, carbonates of alkali and alkaline earth metals, oxalic acid, for example oxalates of alkali and alkaline earth metals, can also be used as additives for combustion moderation.
- Substances such as graphite, water glass, nitrates and perchlorates of the alkali and alkaline earth elements are suitable as coating additives.
- the gas sets defined according to the invention are produced by granulation, in a preferred embodiment into a kind of “ball powder”
- Sphere powder is usually understood to mean a propellant powder made from spherical powder elements, which is usually produced by a special process developed by Olin Mathieson, USA.
- a high-strength nitrocellulose solution in a water-immiscible solvent, for example methyl or ethyl acetate, is added to water with careful stirring distributed in such a way that floating balls form.Warming below the boiling point of the solvent leads to progressive depletion of solvents and thus hardening of the floating balls.
- the process for producing the gas sets according to the invention is thus characterized by simple handling and high safety, since almost exclusively solvent and / or water-moist components are used here.
- the binders defined according to the invention are dissolved in a suitable solvent (for example methyl acetate); for this purpose, the oxidizing agent and the additives are added after the binder has dissolved.
- a suitable solvent for example methyl acetate
- Water is added with stirring to precipitate the granules.
- Water-soluble components can be used after a suitable coating or by encapsulation. If residual solubility still exists, it is possible to work with appropriately saturated solutions.
- the rate of water dropping and the stirring speed the geometry, particle size distribution and bulk density of the granules can be controlled.
- handling additives and combustion behavior can be modified in a manner known per se by coating additives.
- the coatings can be applied either by applying the dry substances or by spraying using methods known per se.
- Granules in the sense of the present invention describe the term derived from granules for accumulations of granules.
- a granulate is therefore an asymmetrical agglomerate of powder particles (whole crystals, crystal fragments or particles).
- the shape of a sphere, a rod, a cylinder, etc. is only approximate and indicated.
- the surface is usually uneven and jagged, the mass in many cases more or less porous.
- An essential criterion of the gas sets according to the invention includes the flammability of the spherical powder. Possible combinations of the components a), b) and / or c) result in compositions which, however, cannot be referred to as combustible spherical powder in the sense of the present invention. In the sense of the present invention, a combustible and therefore powder according to the invention denotes such behavior in which the powder continues to burn after ignition, even if the ignition source is removed.
- the gas sets defined according to the invention are particularly suitable for use in motor vehicle systems such as, for example, belt tensioners or airbags and commercial cartridges for generating gas, for example in bolt-setting devices.
- the gas sets defined according to the invention are characterized by non-toxic fumes and residues.
- Table 1 shows the composition (% by weight) and the safety characteristics of the example mixtures 1 to 3, the specified components for the mixtures according to the invention were weighed in the weight ratios indicated and added to the binders dissolved in methyl acetate. Water was then added with stirring and the resulting granules were filtered off. After drying, the granules were sieved and could be surface-treated.
- BAM Federal Institute for Materials Research and Testing
- burning tests were carried out in a closed 25 ml stainless steel pressure bomb.
- the burn-up tests were carried out by weighing the sample mixtures of 3 g with ignition using a glow wire and 0.2 g of an ignition mixture consisting of boron / potassium nitrate and recording the pressure-time curve using a piezoelectric measuring system.
- Table 2 shows a summary of the pressure rise times ( ⁇ t), the percentages relating to the maximum pressure.
- the composition of the burn-up vapor was determined using a thermodynamic computer program (ICT code) and is shown in Table 2.
