Abstract
The invention relates to a cast charge and application thereof to production of a firework propellant. The cast charge is potassium hydrogen terephthalate prepared by mixing terephthalic acid and potassium hydroxide in water to generate a chemical reaction. The cast charge is applied to production of the firework propellant, wherein the firework propellant is prepared by mixing the following components in percentage by weight: 60-70% of potassium perchlorate, 25-35% of cast charge and 2-5% of adhesive and pelletizing a mixture through a sugar coating machine. During the production of the cast charge disclosed by the invention, raw materials are not directly mixed with a strong oxidant, thus very safe production and transportation of the cast charge are realized; when the cast charge is applied to production of the firework propellant, as long as the cast charge is mixed with the potassium perchlorate and the adhesive before the production and is not mechanically machined and the cast charge is not directly stored and conveyed for a long time, potential safety hazard is greatly reduced; in addition, the usage amount of the firework propellant produced by the cast charge disclosed by the invention is only 6g and is 60% of that of a traditional firework propellant, thus the cost is reduced.
Description
Technical field
The present invention relates to the fireworks production field, specifically be a kind of casting charge and be applied to produce the fireworks propelling charge.
Background technology
The propelling charge that uses in the existing fireworks production is to be packed in proportion to pulverize in the airtight electronic ball mill by saltpetre, charcoal, three kinds of components of sulphur to mix; Carry out compressing tablet with large-sized hydraulic press again, use crusher in crushing to become particulate state, screening back to be finished product after the drying again.This several steps operation all will be passed through mechanical friction, usually blasts in the production or security incident such as fire; The propelling charge that uses during the national regulation fireworks are produced at present in addition must arrive specified manufacturer and buy, and in long-distance transport, also has potential safety hazard, and its security incident also happens occasionally; Restrain up to 10 with traditional propelling charge consumption in addition, resulting cost is also higher.
Summary of the invention
Technical problem to be solved by this invention is the shortcoming that overcomes prior art, and a kind of operation and transportation safety, the casting charge that can reduce cost and working method and application are provided.
Technical scheme of the present invention is: a kind of casting charge, be by benzene dipotassium acid and Pottasium Hydroxide are mixed in water the generation chemical reaction processes to benzene dipotassium potassium hydrogen phthalate.
Casting charge is applied to prepare the fireworks propelling charge, is to form with the coater granulation after the component mixing by following weight percent: potassium perchlorate 60-70%, casting charge 25-35%, tackiness agent 2-5%.
Said tackiness agent is a starch based.
Advantage of the present invention: directly do not mix in the production of (1) casting charge, so its production and transportation are very safe with strong oxidizer; As long as before production, just casting charge is mixed with potassium perchlorate and tackiness agent, do not use mechanical workout when (2) preparing the fireworks propelling charge,, significantly reduced potential safety hazard yet not directly with long-time storage of propelling charge and transportation; (3) the fireworks propelling charge consumption with this casting charge preparation has only 6 grams, is 60% of former fireworks propelling charge, and cost reduces.
Embodiment
Below in conjunction with embodiment the present invention is done further explain.
Embodiment 1
97 grams are dissolved in water to acid of benzene dipotassium and 3 gram Pottasium Hydroxide, stirred at normal temperatures 10-40 minute, generate benzene dipotassium potassium hydrogen phthalate.To be deposited in 60-70 after the filtration
oC oven dry, pulverized 140 mesh sieves, for finished product to benzene dipotassium potassium hydrogen phthalate.
Embodiment 2: casting charge is applied to prepare the fireworks propelling charge,
According to potassium perchlorate 70 grams, casting charge 28 grams, tackiness agent sticky rice flour 2 grams.Mixing the back forms with the coater granulation.Be used for the weapon barrel that fireworks are produced, launching effect is fine.
Embodiment 3: casting charge is applied to prepare the fireworks propelling charge,
According to potassium perchlorate 66 grams, casting charge 30 grams, tackiness agent flour 4 grams.Mixing the back forms with the coater granulation.Be used for fireworks and produce weapon barrel, launching effect is fine.
Embodiment 4: casting charge is applied to prepare the fireworks propelling charge,
Potassium perchlorate 64 grams, casting charge 33 grams, red starch 3 grams of eating of tackiness agent
Mixing the back forms with the coater granulation.Be used for the weapon barrel that fireworks are produced, launching effect is fine.
Claims (3)
