Propellant and applications of the propellant in production of firework emitting agents

Abstract

The invention relates to a propellant and applications of the propellant in production of firework emitting agents, wherein terephthalic acid and potassium hydroxide are mixed in water and are subjected to a chemical reaction to prepare potassium hydrogen terephthalate, ie., the propellant, the propellant is used for preparing firework emitting agents, 60-70% by weight of potassium perchlorate, 25-35% by weight of the propellant, and 2-5% by weight of a adhesive are mixed, and the obtained mixture is granulated with a coating machine to prepare the firework emitting agent. According to the present invention, the direct mixing with the strong oxidant during the propellant production does not exist, such that the safety and the transporting are safe; during the preparation of the firework emitting agent, the mixing of the propellant, the potassium perchlorate and the adhesive is performed before the production, the mechanical processing is not required, and the direct long-term storage and the transporting of the firework emitting agent are not required, such that the potential safety hazard is substantially reduced; and the use amount of the firework emitting agent prepared by usingthe propellant is only 6 g and is 60% of the use amount of the original firework emitting agent, such that the cost is reduced.

Description

technical field [0001] The invention relates to the field of fireworks production, in particular to a propellant and its application in the production of fireworks propellants. Background technique [0002] The propellant used in the existing fireworks production is composed of potassium nitrate, charcoal, and sulfur, which are put into a closed electric ball mill in proportion to be pulverized and mixed, and then pressed into tablets with a large hydraulic press, and then crushed into particles with a crusher after drying. shape, screening for the finished product. These steps of operation have to go through mechanical friction, and safety accidents such as explosions or fires often occur in the production; in addition, the current state stipulates that the propellants used in the production of fireworks must be purchased from designated manufacturers, and there are also potential safety hazards in long-distance transportation. Its safety accident also occurs from time to ...

Problems solved by technology

These steps of operation have to go through mechanical friction, and safety accidents such as explosions or fires often occur in the production; in addition, the current state stipulates that the propellants used in the production of fireworks must be purchased from designated manufacturers, and there are also potential safety hazards in long-distance transportation. Its safety accidents also occur from time to time; in addition, the amount of traditional propellant used is as high as 10 grams, and the total cost is also relatively high
