Embodiment 1

[0018] Embodiment 1: The organic carbon pyrotechnic powder reducing agent is composed of the following components in parts by weight: 30 parts of terephthalic acid; 10 parts of ammonium benzoate; 10 parts of calcium benzoate; 40 parts of potassium hydrogen terephthalate parts; hemp stalk carbon 10 parts. The simple substances of each component are crushed and sieved, and the mesh number of the sieve is 220 mesh, weighed according to the above-mentioned proportion, and mixed uniformly according to the general method to obtain the product. Potassium perchlorate is added to the reducing agent according to the weight ratio of 1:1.7 to obtain the fireworks propellant. The raw materials are commercially available chemical materials. The comprehensive cost of production is reduced by more than 40% compared with military nitrate.

Embodiment 2

[0019] Embodiment 2: The organic carbon pyrotechnic powder reducing agent is composed of the following components in parts by weight: 28 parts of terephthalic acid; 8 parts of ammonium benzoate; 12 parts of calcium benzoate; 42 parts of potassium hydrogen terephthalate parts; fir toner 12 parts. The simple substances of each component are crushed and sieved, and the mesh number of the sieve is 220 mesh, weighed according to the above-mentioned proportion, and mixed uniformly according to the general method to obtain the product. Potassium perchlorate is added to the reducing agent according to the weight ratio of 1:1.7 to obtain the fireworks propellant.

Embodiment 3

[0020] Embodiment 3: The organic carbon pyrotechnic powder reducing agent is composed of the following components in parts by weight: 32 parts of terephthalic acid; 12 parts of ammonium benzoate; 12 parts of calcium benzoate; 38 parts of potassium hydrogen terephthalate part; 8 parts of graphite powder. The simple substances of each component are crushed and sieved, and the mesh number of the sieve is 220 mesh, weighed according to the above-mentioned proportion, and mixed uniformly according to the general method to obtain the product. Potassium perchlorate is added to the reducing agent according to the weight ratio of 1:1.7 to obtain the fireworks propellant.

Description

technical field [0001] The invention relates to a reducing agent for fireworks pyrotechnic powder. Background technique [0002] The role of the reducing agent (also known as combustible) in fireworks and firecrackers is to provide the heat required for the combustion of the drug. The activity of the combustible and the amount of heat provided determine the reaction speed of the pyrotechnic drug. Now commonly used reducing agents in fireworks and pyrotechnics include sulfur, charcoal, aluminum powder, aluminum-magnesium alloys, etc. Mixed with potassium nitrate, potassium perchlorate, etc., it is used as fireworks propellant, explosive (bud) drug, ignition line drug, spray (shot) drug, rocket firework propellant, etc. for fireworks products. The disadvantages of the pyrotechnic powder produced by using the existing reducing agent are: high mechanical sensitivity and no safety guarantee; at the same time, the combustion smoke is large and the sulfur dioxide and sulfide are r...
