Abstract
The invention relates to a propellant for fireworks and crackers. The propellant is prepared from the following four raw materials: potassium perchlorate, potassium hydrogen terephthalate, charcoal powder and an adhesive, wherein the adhesive is glutinous rice flour or phenolic resin. The propellant is prepared by the following steps: mixing: by mass percentage, the four raw materials are put into a gunpowder machine and are uniformly mixed to obtain mixed chemical powder; and prilling: the well mixed chemical powder is added into a solvent and is kneaded into powder balls, and the powder balls are made into small spherical particles by a sugarcoating machine or rubbed into small particles by a screen mesh, and then the propellant for the fireworks and crackers is obtained by drying in the sun. A finished product of the propellant for the fireworks and crackers is prepared from the four raw materials and by the two processes of mixing and prilling, the production technology is simple, ball milling, tabletting, crushing and other processes in which exploding is easy to occur can be omitted, and the safety performance of the propellant is greatly improved. The propellant has the advantages of low hygroscopicity, stable performance, long shelf life, small shot noises, high shot height, small lateral force, low production cost and less use amount, and has obvious price advantage.
Description
Technical field
The present invention relates to a kind of propellant for fireworks and crackers, belong to fireworks and firecrackers and manufacture field.
Background technology
Existing propellant for fireworks and crackers is all to adopt the preparation of raw material of following mass percent to form: saltpetre 70%, charcoal 20%, sulphur 10%, and by weighing, ball milling, granulation, compressing tablet, fragmentation, screening, polished finish, make successively, in this propelling charge, adopt saltpetre to make oxygenant, its advantage is that price is lower, shortcoming is that water absorbability is strong, easy deliquescence propelling charge, the propelling charge quality guaranteed period of producing is short, and mass discrepancy is large, emissivity is not strong, and transverse force is larger.Along with level of industry improves constantly, low in the urgent need to a kind of production and application cost, production technique is simple, stable performance, the propellant for fireworks and crackers of long quality-guarantee period.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of water absorbability little, stable performance, drug dose is few, long quality-guarantee period, production technique is simple simultaneously, and production cost is lower, the propellant for fireworks and crackers that use is safe and reliable.
Technical scheme of the present invention is: a kind of propellant for fireworks and crackers, it is characterized in that described this propellant for fireworks and crackers is to be made by following raw material and step,
The mass percent of described each raw material is:
Potassium perchlorate 40%-70%, terephthaldehyde's potassium hydrogen phthalate 20%-40%,
Wood charcoal powder 5%-20%, tackiness agent 3%-8%,
Any value between above-mentioned each component two-end-point; Each component percentage composition sum is 100%;
Described tackiness agent is the solubility sticky rice flour, or resol;
Described each step is:
(1), mixed medicine, by above-mentioned mass percent by potassium perchlorate, terephthaldehyde's potassium hydrogen phthalate, wood charcoal powder and tackiness agent be placed in the medicine machine in be mixed evenly or artificial three sieve three Hes, obtain mixed powder;
(2), granulation, the mixed powder puddled is adopted to tap water, or industrial spirit makes solvent, namely tackiness agent be the solubility sticky rice flour just with water as solvent from the beginning, tackiness agent is that resol is just made solvent with industrial spirit;
Adopt coater to do the globulate small-particle, while doing, spray spray water xi or alcohol; Or adopt screen cloth to wipe and make small-particle, first water or alcohol Ban Chao You are agglomerating, then wipe and make small-particle with screen cloth; Sizing is the particle of 1.5mm-4mm as required, dries or dry namely to make this propellant for fireworks and crackers.
The present invention compared with prior art has following advantage is arranged:
One, this propellant for fireworks and crackers adopts the less potassium perchlorate of water absorbability to make oxygenant, and terephthaldehyde's potassium hydrogen phthalate that proportion is little is made reductive agent, is equipped with wood charcoal powder and tackiness agent, as long as make finished product by mixed medicine and granulation two procedures; Therefore manufacture craft is simple, and the propelling charge water absorbability of production is little, stable performance, long quality-guarantee period.
Two, the manufacture craft of this propellant for fireworks and crackers is simple, and save prior art and need carry out ball milling, compressing tablet, the technique that fragmentation etc. is easily blasted, and then greatly improved the safety performance of making.
Three, the manufacture craft of novel firework firecracker propelling charge of the present invention is simple, and each factory can produce voluntarily, without Road transport and excessive storage, has substantially stopped the security incident that occurs because of Road transport and excessive storage.
Four, compared with prior art to launch sound little for this propellant for fireworks and crackers, and firing altitude is high, and transverse force is little.
Five, this propellant for fireworks and crackers usage quantity is few, and production cost is lower, with the propellant for fireworks and crackers that uses in prior art, has compared quite significantly price advantage, below is the production pricing:
The propellant for fireworks and crackers price of prior art is 12000 yuan/T.
This propellant for fireworks and crackers price is 8075 yuan/T, specifically is calculated as follows:
Potassium perchlorate 55%*8500 unit/T=4675 unit;
Wood charcoal powder 10%*2000 unit/T=200 unit;
Terephthaldehyde's potassium hydrogen phthalate 30%*9000 unit/T=2700 unit;
Solubility sticky rice flour 5%*6000 unit/T=300 unit;
200 yuan/T of process cost;
Add up to 8075 yuan/T.
For example: take the fireworks display of the high cylinder of 30mm internal diameter 250mm as example:
The propellant for fireworks and crackers dose of prior art is 0.012 yuan/gram of 3.5 gram *=0.042 yuan/send out.
This propellant for fireworks and crackers dose is 0.008075 yuan/gram of 1.5 gram *=0.0121 yuan/send out, and saves 0.0299 yuan, is equivalent to save 71.2% for every.
