Description
[001] O objetivo da presente invenção refere-se a um agente de ignição pirotécnico.[001] The object of the present invention relates to a pyrotechnic ignition agent.
[002] Agentes de ignição pirotécnicos no sentido da invenção são substâncias ou misturas de substâncias, que podem desenvolver um efeito pirotécnico.[002] Pyrotechnic igniters in the sense of the invention are substances or mixtures of substances, which can develop a pyrotechnic effect.
[003] Um objetivo da presente invenção, em particular, é um agente de ignição pirotécnico, que pode ser usado em sistemas de ignição mecânicos, elétricos ou opto-elétricos.[003] An object of the present invention, in particular, is a pyrotechnic ignition agent, which can be used in mechanical, electrical or opto-electrical ignition systems.
[004] A partir do documento DE 102010025104 A1 é conhecido um explosivo de 5,5'-azotetrazolato, que compreende um sal de ferro, cobalto, níquel, cobre, cádmio ou guanilureia de um 5,5'-azotetrazol ou uma mistura de pelo menos um 5,5''-azotetrazolato e pelo menos um triazenato de bistetrazolila ou pelo menos de um outro sal de metal ou sal de guanilureia de um 5,5'-azotetrazol. Os sais ali descritos são neutros, isto é, nem ácidos nem básicos. Os sais de zinco ou cromo do 5,5'-azotetrazol não são resistentes ao armazenamento de acordo com o documento DE 102010025104 A1. Além disso, há o problema, de que misturas contendo tetrazeno não são suficientemente estáveis termicamente, visto que o tetrazeno já se decompõe a 120°C.[004] From document DE 102010025104 A1 a 5,5'-azotetrazolate explosive is known, which comprises an iron, cobalt, nickel, copper, cadmium or guanylurea salt of a 5,5'-azotetrazole or a mixture of at least one 5,5''-azotetrazolate and at least one bistetrazolyl triazenate or at least one other metal salt or guanylurea salt of a 5,5'-azotetrazole. The salts described therein are neutral, i.e., neither acidic nor basic. The zinc or chromium salts of 5,5'-azotetrazole are not storage resistant according to DE 102010025104 A1. In addition, there is the problem that mixtures containing tetrazene are not sufficiently thermally stable, as tetrazene already decomposes at 120°C.
[005] O objetivo da presente invenção foi a disponibilização de um outro agente de ignição pirotécnico. Um outro objetivo da presente invenção foi a disponibilização de um agente de ignição pirotécnico, que pode ser usado em sistemas de ignição mecânicos, elétricos ou opto-elétricos.[005] The objective of the present invention was to provide another pyrotechnic ignition agent. Another objective of the present invention was the provision of a pyrotechnic ignition agent, which can be used in mechanical, electrical or opto-electrical ignition systems.

[0017] As substâncias caracterizam-se pela liberdade de chumbo e bário, por uma alta capacidade de ignição, tempos de reação curtos e correspondentes sensibilidades. Essas propriedades possibilitam uma redução da massa de substâncias explosivas necessárias para a ignição segura.[0017] The substances are characterized by the freedom of lead and barium, by a high ignition capacity, short reaction times and corresponding sensitivities. These properties make it possible to reduce the mass of explosive substances necessary for safe ignition.
[0018] Na tabela 1 são mostradas temperaturas de decomposição, sensibilidades à fricção e ao impacto de exemplos selecionados. A medição das sensibilidades à fricção e ao impacto foi realizada pelos métodos da Bundesanstalt für Materialforschung (BAM) indicados no relatório BAM 142 (1987), enquanto a medição das temperaturas de decomposição foi realizada com a calorimetria diferencial dinâmica (DSC) (empresa Mettler) com uma taxa de aquecimento de 10 K por minuto.[0018] Table 1 shows decomposition temperatures, friction and impact sensitivities of selected examples. The measurement of friction and impact sensitivities was carried out by the methods of the Bundesanstalt für Materialforschung (BAM) indicated in the BAM report 142 (1987), while the measurement of decomposition temperatures was carried out with dynamic differential calorimetry (DSC) (Mettler company) with a heating rate of 10 K per minute.
