Abstract

The invention relates to a waterproof bonding agent for ignition powder and a preparation method of the waterproof bonding agent, and belongs to the field of energy containing and chemical engineering inter-disciplines. The waterproof bonding agent comprises the following components: 80-90% of starch, 2-8% of ethyl cellulose, 3-6% of one or more pre-polymers, 2-5% of one or two curing agents and 1.5-2.5% of a waterproof agent. The prepared waterproof bonding agent, namely an adhesive, is rich in raw materials, economical, non-toxic, harmless, and free of volatility and free formaldehyde release, thereby being an environment-friendly adhesive; meanwhile, the waterproof bonding agent is relatively high in bonding property, strength and water resistance; the energy containing pre-polymers are adopted for the waterproof bonding agent, so that the energy of the waterproof bonding agent can be improved, and then the ignitability of the ignition powder can be effectively improved.

Description

technical field [0001] The invention relates to a waterproof adhesive for ignition medicine and a preparation method thereof, belonging to the interdisciplinary field of energy and chemical engineering. Background technique [0002] The role of the binder in the ignition powder is to combine the components in the ignition powder. The mechanical properties and energy properties of the binder affect the performance of the ignition powder. [0003] At present, the ignition powder all contains potassium perchlorate, potassium nitrate or ammonium perchlorate simple substance or mixture, which causes the disadvantages that the ignition powder is easy to be affected by moisture, corrode the bridge wire and the foot line. Such as by C, KClO 3 After 12 months of storage, the ignition powder composed of adhesives and adhesives will seriously corrode the footlines and bridge wires; 3 After long-term storage, the ignition powder composed of adhesives will corrode the foot line and bri...
