Description
Technical field
The present invention relates to a kind of fireworks and open quick-fried medicine, particularly relate to a kind of not containing metal powder, the not fireworks of sulfur-bearing and open quick-fried medicine.
Background technology
Fireworks and firecrackers is China's traditional feature industries, and annual fireworks and firecrackers industry production value is more than 60,000,000,000 yuan, and fireworks and firecrackers industry is the mainstay industry on the ground such as Liuyang, Liling, for promoting local farmers employment, increasing local fiscal revenue and having played active effect.Recent years, domestic fierce to the pollution repercussion that produces during firework display, directly cause last year domestic fireworks consumption to decline about 30%, wherein the ground such as Beijing, Hangzhou, Wuhan decrease beyond 50%.Firework display pollutes and is mainly caused by two aspects: one is the sound pollution that the lift-off such as combined firework class fireworks cause when opening quick-fried; Two is that the PM2.5 such as the smog of firework medicament burning generation pollute.Simultaneously, external quick-fried medicine opened to the tradition taking metal powder as reductive agent done limitation requirement, wherein the U.S. require to open quick-fried medicine must not containing metal powder, European Union's regulation opens quick-fried medicine content must not more than 2g, can say, the performance opening quick-fried medicine determines the destiny of the lift-off class fireworks based on combined firework.In recent years, Institutes Of Technology Of Nanjing's utilization is made smokeless single base to retired single original washing powder recrystallization and is opened quick-fried medicine, but it needs shaped-charge, causes very difficult industrialization; Liuyang Niu Shi fireworks display factory etc. develop Novel smokeless not sulfur-bearing open quick-fried medicine, it is smokelessly effective, but it is too strong to blast power, and during powder charge, dose controls with great difficulty not cause the critical defects such as fried cylinder.In sum, exploitation is a kind of effective, simple be suitable for smokelessly novel to open quick-fried medicine significant to fireworks industry.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency and defect mentioned in above background technology, provides a kind of remarkable reduction fireworks amount of being fuming, fireworks that environmental-protecting performance is high open quick-fried medicine and preparation method thereof.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is that a kind of fireworks are with opening quick-fried medicine, these fireworks are driven quick-fried cartridge bag and are drawn together following component: 35 ~ 45 weight part Potassium Hydrogen Phthalates, 30 ~ 40 weight part potassium perchlorates, 15 ~ 25 weight part coke and 3 ~ 5 weight part priming charges, and the component of described priming charge comprises: 55 ~ 60 weight part potassium perchlorates, 30 ~ 35 weight part waste of flax carbon and 3 ~ 5 parts by weight resin.Wherein coke is as reductive agent, has the effect producing gas simultaneously; Resin plays bonding, acts on uniformly in priming charge, can cross easy handling priming charge.
Above-mentioned fireworks are with opening in quick-fried medicine, and preferably, described coke is one-level coke.
Above-mentioned fireworks are with opening in quick-fried medicine, and preferably, described resin is resol or shellac.
Above-mentioned fireworks are with opening in quick-fried medicine, and preferably, the described fireworks impact sensitivity and friction sensitivity opening quick-fried medicine is respectively 0 ~ 20% and 0 ~ 20%, and rate of moisture absorption is 1 ~ 2%.
As a total technical conceive, the present invention also provides a kind of above-mentioned fireworks preparation method opening quick-fried medicine, comprises the following steps: coke powder is broken to 200 orders with pulverizer stand-by; By each for the coke after Potassium Hydrogen Phthalate, potassium perchlorate, pulverizing mistake 100 mesh sieve, extracting screen underflow is by proportioning mixing; Then cross 100 mesh sieve 4 times, additional priming charge, then mixture is crossed 100 mesh sieve 2 times, extracting screen underflow, namely obtain fireworks and open quick-fried medicine.
Compared with prior art, the invention has the advantages that:
(1) fireworks of the present invention open quick-fried medicine not containing sulphur, not containing metal powder, not containing the forbidden drug that hexachlorobenzene, lead compound, oxymuriate, arsenic compound etc. prohibit the use both at home and abroad.
(2) fireworks of the present invention open quick-fried medicine impact sensitivity and friction sensitivity is respectively 34% and 26%, lower than 50% of national regulations and the restriction of 60%, safe and reliable.After 75 DEG C of heat-resistant quality tests, medicament does not produce burning, blast Sum decomposition, stable and reliable for performance; Rate of moisture absorption is 1.2%, lower than the restriction of 2.0% of national regulations, and lower than the water absorbability of traditional black powder, guarantees medicament long time stability.
(3) the time m-pressure curve rise time (during ignition, pressure rises to 2.07Mpa from 0.69MPa) of quick-fried medicine opened by fireworks of the present invention is 0.6ms, the tradition being better than potassium perchlorate+magnesium aluminum-alloy powder opens quick-fried medicine, and when the burning of quick-fried medicine opened by fireworks of the present invention, the amount of being fuming only is equivalent to traditional baiyao and opens quick-fried medicine and 30% of quick-fried medicine opened by black powder.
(4) starting material used in the present invention are all the starting material generally used in current fireworks industry, and price is suitable with conventional formulation; Technique is relatively simple, and product is easy to utilize, has good use value.The present invention's amount of being fuming is little, meets environmental requirement, and the technical requirements of energy breaks through foreign, has good application value simultaneously.
