Definitions
- Pyrotechnic agents in the context of the invention are substances or mixtures of substances which can develop a pyrotechnic effect.
- the subject of the present invention is a pyrotechnic agent which can be used as a thermal ignition agent.
- thermal pre-ignition agents are, for example, safety systems, preferably thermal fuses in gas generators or separating elements for batteries.
- security systems are again preferably used in motor vehicles.
- Thermal pre-ignition agents are pyrotechnic substances or mixtures which, inter alia, have the task of controlling the usually very thermally stable gas-generating mixtures of the gas generator in the event of a vehicle fire.
- thermal preignition agents are the use as a pyrotechnic set in separators, preferably for battery terminals. These separators should interrupt the power supply in case of fire, especially a vehicle fire, or in a motor vehicle accident in which the gas generator is triggered.
- thermal thermal ignition agents are nitrocellulose, propellant powders derived therefrom or those disclosed in the patent application DE 197 30 873 A1 used mixtures based on nitrotriazolone and guanidine nitrate. These mixtures show ignition temperatures of about 160 ° C and are insufficiently long-term stability in the case of nitrocellulose.
- Object of the present invention was to provide a pyrotechnic agent having an ignition temperature of 180 ° C and sufficient long-term stability. Another object of the present invention was to provide a pyrotechnic agent that can be used as a thermal ignition agent for gas generators in automotive safety systems. A Another object of the present invention was to provide a pyrotechnic agent that can be used in battery terminal isolators.
- azotetrazolates are used as component according to the invention.
- the azotetrazolate component used here is amino guanandine 5,5'-azotetrazolate (C 4 H 14 N 18 ), AGATZ for short, and guanidine 5,5'-azotetrazolate (C 4 , H 12 N 16 ), short GATZ.
- the US-A-6007,647 offers thermal pre-ignition agents containing GATZ and two oxidants.
- the azotetrazolate components may be used either alone or in mixtures with each other and / or with other components.
- the structural formulas of AGATZ and GATZ are as follows:
- Aminoguanine 5,5'-azotetrazolate (C 4 H 14 N 18 , AGATZ).
- Guanidine 5,5'-azotetrazolate (C 4 , H 12 N 16 , GATZ).
- the deflagration point of the pure AGATZ is 209 ° C, that of the GATZ is 240 ° C.
- the deflagration temperatures in the range of 165 ° C to 195 ° C can be controlled and the deflagration temperatures of the mixtures can be lower than that of the individual components.
- the production and processing takes place according to known and customary methods. These include, for example, kneading, extrusion, extrusion, tabletting or granulation.
- Table 2 shows the deflagration points, friction and impact sensitivities of the mixtures.
- the measurement of the friction and impact sensitivities was carried out according to methods of the Federal Institute for Materials Research (BAM), while the measurement of the deflagration points was carried out with the thermogravimetric analysis (Mettler) at a heating rate of 10 ° C. per minute.
- Table 3 summarizes the weight losses and deflagration points after thermal stress (24 h, 125 ° C and 400 h, 110 ° C) of some of the mixtures selected from the examples.
- the weight loss was measured analogously to the Holland test.
- the measurement of the deflagration points was carried out by thermogravimetric analysis (Mettler) at a heating rate of 10 ° C per minute.
