Title:
PROCESS FOR PREPARATION OF ELECTROPYROTECHNIC INITIATOR BY USE OF AQUEOUS ADHESIVE
Document Type and Number:
Japanese Patent JP3860534
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To solve the problems in safety, such as handling of explosive substances in the presence of flammable substances, heating of the flammable substances to a high temperature or formation of toxic vapor in the process of using a varnish dissolved in a solvent as there is a need for firmly contacting a pyrotechnic substance and a resistive element in the preparation of an initiator.
SOLUTION: The process for the preparation of the electropyrotechnic initiator 1 including the pyrotechnic varnish 6 initiated by the resistive heating element 11, in which the pyrotechnic varnish is obtained by deposition, on the resistive element, of an aqueous adhesive composed of a dispersion of an explosive substance and of additives in an aqueous suspension based on a copolymer and then by drying the said aqueous adhesive at a temperature of between 55°C and 75°C. The polymer is chosen from ethylene/vinyl acetate copolymers and vinyl acetate/ethyleneacetate/ethylene copolymers.
