Problems solved by technology

[0002] Firework shells and combined fireworks are fired by propellant powder to push pyrotechnic powder effect parts to the design height. At present, all of them are military nitrate grains composed of black powder. The mass ratio of its components is generally potassium nitrate: sulfur: charcoal is 69:7:24. Relatively speaking, the quality is relatively stable, but there is a big disadvantage that due to the sulfur in the composition, the sulfur dioxide and other toxic gas pollution produced after sulfur combustion The environment has a great negative impact on people's living environment
According to the strengthening of the national environmental protection policy, this kind of product that will cause toxic gas pollution such as sulfur dioxide no longer meets the requirements of the times

Embodiment Construction

[0008] A specific embodiment of the present invention is as follows, an environmentally friendly sulfur-free propellant formulation method, according to the following component mass ratio components: potassium perchlorate, potassium hydrogen terephthalate, charcoal, phenolic resin as the constituent materials, with 60:35: 2:3 is its mass ratio component.

[0009] The production process of environmentally friendly sulfur-free propellants is:

[0010] (1) Single-material screening: Potassium perchlorate passes through a 100-mesh sieve, charcoal passes through a 160-mesh sieve, and phenolic resin and potassium hydrogen terephthalate reach 120 mesh or more, which can be passed through;

[0011] (2) Weighing: Weigh 0.6 kg of potassium perchlorate, 0.35 kg of potassium hydrogen terephthalate, 0.02 kg of charcoal, and 0.03 kg of phenolic resin after the previous process;

[0012] (3) Mixing: fully mix the four weighed materials through a 100-mesh sieve, and then repeat the mixing an...

Abstract

The invention discloses an environment-friendly sulfur-free propellant formula. According to the formula, potassium perchlorate, potassium terephthalate hydrogen, wood charcoal and a phenolic resin are taken as ingredients and are in a mass ratio of 60:35:2:3. According to the environment-friendly sulfur-free propellant formula, the combustion products are mainly carbon dioxide and water. Due to the absence of sulfur, sulfur dioxide and other harmful gases are not released after combustion, and the defect that sulfur dioxide and harmful gas substances are generated after the propellant containing sulfur is combusted is overcome. Moreover, drug performance is very stable in the using process, is difficultly dampened as compared with black powder (military nitrate), and an identical effect can be achieved by taking 1 / 3 sulfur-free propellant in the black powder (military nitrate) only.

Description

technical field [0001] The invention relates to an environmentally friendly sulfur-free propellant formula, in particular to an environmentally friendly sulfur-free propellant formula used in fireworks shells and combined fireworks, and belongs to the technical field of gunpowder. Background technique [0002] Firework bombs and combined fireworks are fired by the propellant to push the pyrotechnic powder to the design height. At present, the military nitrate grains are all black gunpowder. The mass ratio of the components is generally potassium nitrate: sulfur: charcoal is 69: 7:24, relatively speaking, the quality is relatively stable, but there is a big disadvantage that because the ingredients contain sulfur, sulfur dioxide and other toxic gases produced after sulfur combustion pollute the environment, which has a great negative impact on people's living environment. According to the strengthening of the national environmental protection policy, this kind of products th...
