Technical Field

The invention relates to the field of ignition powder, in particular to a novel efficient igniter medicament.

Background

With the development of national economy, the application of igniters is continuously expanding. Particularly, as the automobile production and automobile consumption in China continue to maintain the world's largest scale for years, the use scale of the igniter applied to the automobile airbag device is also continuously enlarged.

The ignition agent is a core component of the igniter, and the performance of the ignition agent directly influences the performance of the igniter. Ignition stability and reliability of the igniter are important, particularly in the application to an airbag device for a vehicle. The higher the ignition success rate of the igniter of the automobile air bag device is, the safer the igniter is, so the ignition performance of the igniter needs to be improved continuously, but in recent years, the ignition success rate level of the igniter is not obviously improved and is in a bottleneck state of development. Therefore, it is very important to develop a new type of high efficiency ignition agent for improving the success rate of ignition.

Disclosure of Invention

A novel efficient ignition agent for an automobile safety airbag device is shorter in ignition completion time, smaller in fluctuation and higher in ignition success rate, and is suitable for use in an ignition tool of an automobile safety airbag device and the like.

A novel high-efficiency igniting agent for medical appliances comprises strontium, magnesium, manganese dioxide, polyaziridine glycidyl ether, hexogen and N, N' -diaminoformylhydrazine.

Preferably, the components and the proportion thereof are 15-30 wt% of strontium, 5-20 wt% of magnesium, 40-60 wt% of manganese dioxide, 5-15 wt% of polyaziridine glycidyl ether, 1-10 wt% of hexogen and 1-10 wt% of N, N' -dicarbamic acid hydrazide.

Preferably, the particle size of strontium, magnesium, manganese dioxide, hexogen, N' -dicarbamohydrazide is 50 μm or less.

The invention has the following beneficial effects:

the ignition completion time of the agent is shorter, the fluctuation of the ignition completion time is smaller, the full ignition current value is lower, the ignition success rate is higher, and the agent is very suitable for being used in the aspects of automobile safety devices and the like.

Detailed Description

To facilitate an understanding of the invention, illustrative examples follow. The examples are only for the purpose of facilitating understanding of the present invention and should not be construed as specifically limiting the present invention.

Test sample preparation: weighing 20 g of strontium, 10 g of magnesium, 50 g of manganese dioxide, 10 g of polyaziridine glycidyl ether, 3 g of hexogen and 3 g of N, N' -dicarbamoyl hydrazine, mixing and adjusting to obtain a test sample.

Example 1

A proper amount of test samples are loaded in a cavity of an igniter tester according to an operation specification, then the ignition tester is installed in a closed test cylinder, and is electrified for testing, and an internal pressure rising curve is measured by using a pressure sensor installed in the test cylinder, and the result is shown in the attached drawing of the specification.

The test result shows that the agent of the invention burns quickly after being ignited, and is suitable for an igniter. Under the same conditions (room temperature, current value and the like), the ignition completion time of the medicament is reduced by 31 percent compared with the traditional product, the standard deviation of the ignition completion time is reduced by 25 percent compared with the traditional product, and the stability is better, and the results are shown in the following table 1.

Example 2

According to the operating specification, the ignition current of the test sample is measured after being electrified for 2ms at room temperature, and the full ignition current value is calculated by a statistical method commonly used in the industry, and the result shows that the full ignition current value of the medicament is reduced by 16 percent compared with the traditional product under the same condition, and the specific result is shown in the following table 2.

Example 3

The ignition or non-ignition results of the test samples are repeatedly confirmed according to the operating specifications, and the ignition success rate is calculated by a statistical method commonly used in the industry, and the results show that the ignition success rate of the medicament is higher than that of the traditional product, and the specific results are shown in the following table 3.

The above-mentioned embodiments are further detailed descriptions of the technical solutions and the advantages of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
