Abstract
The invention relates to safe gunpowder for fireworks, which is prepared from the following raw materials in parts by weight: 20-30 parts of potassium dichromate, 10-15 parts of potassium nitrate, 5-10 parts of nitroguanidine, 20-50 parts of single-base powder, 15-35 parts of diphenylamine and 5-10 parts of carbon.
Description
Technical Field
The invention relates to the technical field of pyrotechnic compositions, in particular to a safe pyrotechnic composition for fireworks.
Background
The fireworks are made by using pyrotechnic compositions as main raw materials, and produce the effects of light, sound, color, shape, smoke and the like through combustion or explosion after ignition, and are used for appreciation. In production, pyrotechnic compositions are one of the important raw materials. In the prior art, the pyrotechnic composition contains sulfur, sulfur dioxide and sulfide generated during combustion can cause air pollution, and smoke is large; secondly, the propellant has the characteristics of high sensitivity and low ignition point, and accidents are easily caused in the production and transportation processes; thirdly, the pyrotechnic composition has strong hygroscopicity and is easy to deliquesce, so that the guarantee period of the pyrotechnic composition is short. In view of the restriction of various factors and the problems in the prior art, the invention seeks a new pyrotechnic composition to achieve the ideal effects of less smoke, safety and environmental protection.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a pyrotechnic composition which has simple components, no sulfur, good stability, strong friction and high pressure capacity, strong moisture resistance and only a small amount of micro smoke during setting off, thereby meeting the requirements of the existing firework production safety standard and environmental protection setting off.
The technical solution of the invention is as follows:
the safe gunpowder for fireworks is prepared from the following raw materials in parts by weight: 20-30 parts of potassium dichromate, 10-15 parts of potassium nitrate, 5-10 parts of nitroguanidine, 20-50 parts of single-base powder, 15-35 parts of diphenylamine and 5-10 parts of carbon.
Preferably, the safe gunpowder for fireworks is prepared from the following raw materials in parts by weight: 25 parts of potassium dichromate, 10 parts of potassium nitrate, 8 parts of nitroguanidine, 35 parts of single-base powder, 20 parts of diphenylamine and 10 parts of carbon.
Further, the preparation method of the safety powder for fireworks comprises the following steps: the preparation method comprises the steps of uniformly mixing potassium dichromate, potassium nitrate, nitroguanidine, single-base powder and diphenylamine, adding carbon powder, performing three-sieve mixing manually, sieving the obtained mixed powder by using a sieve of 100 meshes, adding water, uniformly stirring, then feeding the obtained mixed powder into a granulator for granulation, and finally drying to obtain the potassium dichromate-potassium nitrate-nitroguanidine-base powder.
Compared with the prior art, the pyrotechnic composition prepared by the invention has the following advantages and positive effects:
1. the propellant produced by the invention does not contain sulfur, arsenic, lead, mercury and sulfide, greatly reduces atmospheric pollution, discharges less smoke in the combustion process and has obvious environmental protection benefit.
2. The pyrotechnic composition has less usage amount and obvious economic benefit.
3. The preparation method is simple, the existing processes of tabletting, polishing and the like which are easy to explode are omitted, the production benefit is improved, and the safety performance of the pyrotechnic composition preparation is improved.
The specific implementation mode is as follows:
the invention will be further illustrated with reference to specific examples.
Example 1: 20 parts of potassium dichromate, 10 parts of potassium nitrate, 5 parts of nitroguanidine, 20 parts of single-base powder, 15 parts of diphenylamine and 5 parts of carbon.
The preparation method comprises the following steps: firstly, uniformly mixing potassium dichromate, potassium nitrate, nitroguanidine, single-base powder and diphenylamine, then adding carbon powder, then adopting an artificial three-sieve, sieving the obtained mixed powder by using a 100-mesh sieve, adding water, uniformly stirring, then sending the obtained mixture into a granulator for granulation, and drying the obtained granules until the water content is below 2% to obtain the required pyrotechnic composition.
Example 2: 25 parts of potassium dichromate, 10 parts of potassium nitrate, 8 parts of nitroguanidine, 35 parts of single-base powder, 20 parts of diphenylamine and 10 parts of carbon.
The preparation method comprises the following steps: firstly, uniformly mixing potassium dichromate, potassium nitrate, nitroguanidine, single-base powder and diphenylamine, then adding carbon powder, then adopting an artificial three-sieve, sieving the obtained mixed powder by using a 100-mesh sieve, adding water, uniformly stirring, then sending the obtained mixture into a granulator for granulation, and drying the obtained granules until the water content is below 2% to obtain the required pyrotechnic composition.
Example 3: 30 parts of potassium dichromate, 15 parts of potassium nitrate, 10 parts of nitroguanidine, 50 parts of single-base powder, 35 parts of diphenylamine and 10 parts of carbon.
The preparation method comprises the following steps: firstly, uniformly mixing potassium dichromate, potassium nitrate, nitroguanidine, single-base powder and diphenylamine, then adding carbon powder, then adopting an artificial three-sieve, sieving the obtained mixed powder by using a 100-mesh sieve, adding water, uniformly stirring, then sending the obtained mixture into a granulator for granulation, and drying the obtained granules until the water content is below 2% to obtain the required pyrotechnic composition.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modifications, changes in materials, and equivalents thereof, which are made according to the technical spirit of the present invention, are within the scope of the present invention.
