Problems solved by technology

With regard to the analysis of the fireworks propellant in the prior art, many enterprises mainly carry out R&D and innovation from the two directions of improving the existing black powder components and adopting single- and double-base powders (nitrocellulose) that have been decommissioned from military industry and converted to civilian use. The analysis of the invention patents of fireworks and propellants in the patent literature published by the State Intellectual Property Office in 2009 is inseparable from potassium salts and ammonium salts or nitrocellulose drugs as oxidants + plant-based carbon powder or metal-based combustible agents + viscose The composition of the mixture, although the propellant of these invention patent compositions has less smoke, there is still a lot of smoke. It is easy to cause safety accidents due to explosion, some material costs and production costs are too high, some are easy to absorb moisture, and the shelf life is too short. For promotion and application in actual production, some invention patents are still on paper, and it is difficult to convert them into production
The existing smokeless medicine / environmental protection medicine can not fully meet the national standards of smokeless, dust-free, tasteless, non-toxic, safe, low-carbon and environmental protection

Embodiment 1

[0029] After each smoke-free raw material (powder or microcrystalline) is prepared, the following components are preferably prepared according to their weight and number ratios: 5 parts by weight of N-amidinourea dinitramide, furfuryldiazide 5 parts by weight of a mixture of Z and 4,4'-bis(4-nitro-3-oxofurazanyl) azofurazan, 2 parts by weight of carboxymethyl cellulose, and mix the components evenly, An appropriate amount of water is added to stir and mix to form a semi-dry-wet state, and then granulated. After the granules are naturally dried or dried, the finished product of the safe and environment-friendly fireworks propellant of the present invention is obtained. In this embodiment, the two kinds of drug component mixtures of diazide azofurazan and 4,4'-bis(4-nitro-3-oxazofurazanyl) azofurazan The ratio of parts by weight is 1:1.

Embodiment 2

[0031] After each smoke-free raw material (powder or microcrystalline) is prepared, the following components are preferably used according to their weight and number ratios: 60 parts by weight of N-guanidinourea dinitramide, 3,6-bis(azide base)-1,2,4,5-tetrazine and 80 parts by weight of a mixture of lanthanum phthalate, 10 parts by weight of carboxymethyl cellulose, and the same processing method as in Example 1 is used to prepare the safety and environmental protection product of the present invention The finished product of fireworks propellant. In this embodiment, the ratio of parts by weight of the mixture of 3,6-bis(azido)-1,2,4,5-tetrazine and lanthanum phthalate is 1:0.3.

Embodiment 3

[0033] After each smoke-free raw material (powder or microcrystalline) is prepared, the following components are preferably prepared according to their weight and number ratios: 35 parts by weight of N-amidinourea dinitramide, dinitroazodifurazan With 60 parts by weight of the mixture of modified nitroguanidine and 5 parts by weight of carboxymethyl cellulose, the same processing method as in Example 1 was used to obtain the finished safe and environment-friendly fireworks propellant powder of the present invention. In this embodiment, the ratio of parts by weight of the mixture of two pharmaceutical components, dinitroazodifurazan and modified nitroguanidine, is 1:0.3.

Abstract

The invention discloses a safe and environmentally-friendly firework propellant powder. The propellant powder comprises, by weight, 5-60 parts of a smokeless oxidant which is a novel high-energy insensitive material N-guanylurea dinitramide, 5-80 parts of a smokeless reducing agent which is a mixture containing any two or more of diazidoazoxyfurazan, 4,4'-bis(4-nitro-3-azoxyfurazyl)azoxyfurazan, cyclobisazotetrafurazan, lanthanum phthalate, 3,6-bis(azido)-1,2,4,5-tetrapiperazine, dinitroazodifurazan, modified nitroguanidine and potassium dichromate, and 2-10 parts of a smokeless adhesive which is carboxymethyl cellulose. The propellant powder has the advantages of realization of no smoke, no toxicity, no smell and no dust pollution in the set-off process, good moisture resistance, stable medical property, convenience in storage and transportation, and simplicity in processing and preparation.

Description

technical field [0001] The invention belongs to the technical field of pyrotechnics, in particular to a safe and environment-friendly fireworks propellant. Background technique [0002] Safety, low-carbon, environmental protection, and green are the basic requirements for human survival. However, in real life, safety and environmental protection have not attracted people's attention in many fields. As far as the fireworks and firecrackers that people love to see, although they have been used for thousands of years It has brought people unlimited joy and auspiciousness, and also provided considerable economic benefits and opportunities for social employment, but fireworks manufacturers have also paid a lot of loss of life and property for this. It is mainly manifested in the potential safety hazards in the production, storage and transportation of fireworks and firecrackers, causing casualties to occur from time to time, as well as a large amount of black smoke and a large am...
