Embodiment 1

[0027] To prepare an igniter potion:

[0028] Weigh 45% of titanium hydride with a particle size of less than 10 μm and a hydrogen content of less than 2%, 53% of potassium perchlorate with an average particle size of less than 20 μm, 1.8% of glucose with a particle size of less than 10 μm, and 0.2% of fluororubber. The solvent is acetone. First pour the fluororubber into the wet mixing granulator, turn on the stirring paddle, stir slowly, then pour the titanium hydride into the equipment, wait for the titanium hydride powder to be completely wet, then add potassium perchlorate and glucose in sequence, and finally add acetone , increase the speed of the stirring paddle, stir for 15 minutes, turn on the cutting knife, and run for 15 minutes, wait until the medicine turns into a ball, stop the equipment, and discharge. Pour the wet-mixed medicine into the swing granulator with CQ11 sieve, and turn on the equipment to complete the granulation. Finally, use the vibrating screeni...

Embodiment 2

[0030] To prepare an igniter potion:

[0031] The preparation method is the same as in Example 1, wherein the raw material components are: 20% titanium powder, 78% potassium chlorate, 0.5% carbon powder, 1.5% fluorine rubber, and the solvent is acetone.

Embodiment 3

[0033] To prepare an igniter potion:

[0034] The preparation method is the same as in Example 1, wherein the raw material components are: 35% titanium powder, 60% ammonium perchlorate, 1% carbon powder, 4% fluorine rubber, and the solvent is acetone.

Abstract

The invention discloses an igniter reagent of an airbag device. The igniter reagent comprises the following raw material components in percentage by mass: 20-45% of a combustible agent, 50-78% of an oxidant, 0.5-5% of a combustion improver and the balance of an adhesive, wherein the total mass percentage of the components is 100%. A preparation method of the igniter reagent comprises the following steps: performing wet mixing on the raw materials, cutting a reagent into spheres, putting the spheres into a granulator for pelletizing, screening uniform reagent granules, and finally drying the regent, thereby obtaining the igniter reagent. The igniter reagent disclosed by the invention has a good ignition function, is relatively low in percussion sensitivity degree, friction sensitivity degree and static electric spark sensitivity degree, is not self-combusted when being heated, collided and the like, is relatively high in security in both the production process and the use process, and is simple in preparation method, low in raw material price, low in cost, applicable to large-scale on-batch production and relatively high in cost performance.

Description

technical field [0001] The invention belongs to the technical field of automobile airbag devices, in particular relates to an igniter medicament for an airbag device, and also relates to a preparation method of the igniter medicament. Background technique [0002] The igniter is an important part of the airbag. When the car collides, the igniter is activated by an electrical signal, and the igniter accurately and timely ignites the subsequent components such as the gas-generating powder, the powder, or the micro-gas generator in the gas generator. , so the igniter is the first safety lock of the airbag device. [0003] An ideal igniter can generate heat through the bridge wire under standard current requirements, igniting the agent in the igniter, so as to realize the function of igniting subsequent components. At the present stage, the agent used in the igniter is mainly zirconium powder-potassium perchlorate ignition agent. There are big problems in the use of this agent:...
