Embodiment 1

[0012] Embodiment 1: The preparation process of the micro-smoke ignition agent is as follows:

[0013] 1. Pass the high-energy reducing agent-aluminum-magnesium alloy powder through a 200-mesh standard sieve;

[0014] 2. According to the ratio of parts by weight, get 78 parts of single and double base powders, 10 parts of potassium perchlorate, 5 parts of hemp stalk charcoal powder, 5 parts of aluminum-magnesium alloy powder, and 2 parts of lead azide. The method of sieving is mixed evenly, then slurried with starch solution, dried and ground. That is, the preparation of the micro-smoke ignition agent is completed. Each component material of the present invention can be bought in firecracker raw material market or chemical industry market according to said name.

Embodiment 2

[0015] Embodiment 2: the difference from Example 1 is that the composition and the weight and number ratio of the light smoke ignition agent are: 27 parts of single and double base powders, 40 parts of nitroguanidine, 15 parts of potassium perchlorate, pine charcoal 10 parts of powder, 10 parts of titanium hydride, 3 parts of nickel hydrazine nitrate.

Embodiment 3

[0016] Embodiment 3: The difference from Example 1 is that the composition and the ratio of parts by weight of the micro-smoke ignition agent are: 35 parts of single and double base powders, 5 parts of potassium perchlorate, 7 parts of Chinese fir charcoal powder, metal aluminum 3 parts of powder, 1 part of nickel hydrazine nitrate.

Abstract

The invention discloses a micro smoke ignition agent for fireworks, which consists of potassium perchlorate, carbon powder, nitro-cotton and / or nitroguanidine, a high-energy reducing agent and a detonation agent. The invention has the advantages that: an oxidant adopts a high-oxygen content and high-stability substance, so that the using amount can be controlled and smoke can be reduced; combustibles can release a large amount of heat during combustion, so that a high-temperature substance is generated; therefore, the using amount can be controlled and the smoke can be reduced; and main combustibles adopt high-oxygen content substances, so that the using amount of smoke oxidants can be reduced to the greatest extent. Therefore, only micro smoke is generated during combustion of the ignition agent. Due to the detection result of light transmittance, compared with that of the conventional same-class corresponding products, the produced smoke is reduced by 70 percent. Meanwhile, the configuration of the whole medicament system guarantees ignition performance and stability of the ignition agent, and the safety performance meets the requirement of the national standard.

Description

technical field [0001] The invention relates to a pyrotechnic composition, in particular to a micro-smoke ignition agent for fireworks. Background technique [0002] The igniting agent for fireworks is used on fireworks bright beads, powder pillars, handles, stars and other parts with drug effects. It is burned after being ignited by propellant or explosive, and then ignites the effect agent with higher ignition point. In the prior art, the ignition agents for fireworks are all made of black powder with different proportions or black powder plus potassium perchlorate and aluminum-magnesium alloy powder. It burns with a lot of smoke. Seriously affect the fireworks display effect, causing environmental pollution. Contents of the invention [0003] In order to overcome the above-mentioned disadvantages, the technical problem to be solved by the present invention is to provide a light-smoke igniting powder that only has a small smoke after being set off and can maintain the ...
