[0015] The exothermic composition according to the first embodiment of the present invention will be described below.

[0016] The exothermic composition of the first embodiment includes: magnesium aluminum alloy (A1), oxidizing agent (B), and binder (C). The water content of the exothermic composition is not more than 1.0% by mass.

[0017] (A1) Magnesium-aluminum alloy is an alloy of aluminum (Al) and magnesium (Mg) contained in an exothermic composition as a fuel component. Preferably, the composition ratio of Mg to Al in the magnesium-aluminum alloy is in the range of 20:80 to 70:30, more preferably 35:65 to 65:35. Magnesium-aluminum alloys may contain one or more metal components other than aluminum or magnesium. Examples of other metal components include: Calcium (Ca), Manganese (Mn), Lithium (Li), Silicon (Si), Antimony (Sb), Strontium (Sr), Zinc (Zn), Zirconium (Zr), Scandium (Sc ), yttrium (Y), tin (Sn) and rare earth metals. Magnesium-aluminum alloys may contain ...

[0034] The exothermic composition of the second embodiment of the present invention will be described in detail below. In the description, the differences from the first embodiment are emphasized.

[0035] The exothermic composition of the second embodiment includes: boron (A2), oxidizing agent (B), binder (C), and 5-aminotetrazole. The water content of the exothermic composition is not higher than 0.7% by mass. The exothermic composition of the second embodiment is different from the exothermic composition of the first embodiment in that it contains boron (A2) instead of magnesium-aluminum alloy (A1), contains 5-aminotetrazole, and the water content of the exothermic composition is not high In 0.7% parts by mass.

[0036] The exothermic composition of the second embodiment contains boron (A2) as a fuel component. Boron is included in the exothermic composition in powder form. Preferably, the average particle diameter of boron is in the range of 0.1 μm to 100 μm, more pref...

Abstract

A heat-generating composition is produced by blending magnalium (A1), an oxidizing agent (B), at least one binder (C) selected from a cellulose-based water-soluble polymer and a vinyl-based water-soluble polymer, and a solvent containing water as a main component, and drying the mixture thereof. The heat-generating composition has a water content ratio of not higher than 1.0% by mass. The invention also relates a method for manufacturing the heat-generating composition.

Description

technical field [0001] The present invention relates to a heat-generating composition having high flammability and combustibility to generate a large amount of heat, such as a heat-generating composition for rapidly heating stored gas in a hybrid inflator to a high temperature, and the present invention relates to A method for producing the exothermic composition. Background technique [0002] An airbag device is installed in a motor vehicle such as a passenger car so that gas injected from a gas generator (inflator) inflates the airbag. Airbag devices are installed to protect motor vehicle occupants from shocks caused by collisions. A gas generator for an airbag device is disclosed in, for example, Japanese Patent Laid-Open No. 2004-149097. [0003] The airbag device disclosed in Japanese Patent Laid-Open No. 2004-149097 has a substantially tubular gas generator. In this gas generator, a first chamber and a second chamber are provided. In the gas generator, the first an...
