Embodiment 1

[0012] Embodiment 1: described bamboo cellulose propellant can be prepared according to the following method:

[0013] One, the preparation method of polymerization oxidant comprises the steps:

[0014] One, get potassium nitrate 78% by weight percentage, potassium ethoxide 12%, potassium dichromate 10% mix;

[0015] 2. Dissolve the mixture of the above step in water, add a catalytic amount of camphor, and heat to boiling; then filter, the sieve is the solid impurities that need to be removed, and the filtered solution is precipitated, cooled, dried, and air-dried, and the obtained powder is For the polymerization oxidant. In the above process, potassium nitrate, potassium ethoxide, and potassium dichromate are polymerized and clustered based on nitro radicals and potassium ions to form a polymer oxide with excellent performance, safety, stability and environmental protection.

[0016] Its two, according to percentage by weight: polymerization oxidant 40%, smokeless bamboo c...

Embodiment 2-5

[0018] Embodiment 2-5 differs from embodiment 1 in that the proportioning of each component is different, see the following table:

[0019]

[0020] The propellant prepared by the above method was tested based on GB 10631-2013 and AQ4104-2008. The actual measurement results showed that the friction sensitivity was 22, the impact sensitivity was 38, the decomposition temperature was 75°C, and the moisture absorption rate was 1.2.

Abstract

The invention discloses bamboo-cellulose propellant powder. The bamboo-cellulose propellant powder is prepared from a polymeric oxidizing agent, a composite reducing agent and a binding agent; the polymeric oxidizing agent is obtained by polymerization reaction of potassium nitrate, potassium ethylate and potassium dichromate; a catalyst for polymerization reaction is camphor; the composite reducing agent is prepared by mixing smokeless bamboo cellulose, carbon powder and hemp stalk charcoal. The bamboo-cellulose propellant powder disclosed by the invention has the beneficial effects that thesafety performance is ensured, and the safety in production, granulation, transportation and setting off is greatly improved; the setting-off pollution is low, and little smoke is generated, so that the environment-friendly performance is good; the cost is low.

Description

technical field [0001] The invention relates to a pyrotechnic powder, in particular to a fireworks propellant. Background technique [0002] In actual production at present, firework propellants have been using black gunpowder (military nitrate) composed of potassium nitrate, charcoal and sulfur. In addition, a large amount of oxides and residues of carbon, sulfur, and potassium remain in the air, seriously polluting the environment. Contents of the invention [0003] In order to solve the above disadvantages, the technical problem to be solved by the present invention is to provide a safe, stable and low-cost environment-friendly fireworks propellant composition. In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is bamboo cellulose propellant, which is characterized in that the propellant is made up of a polymerization oxidant, a composite reducing agent and a binding agent: the polymerization oxidant is com...
