Description
Technical Field
The invention relates to a waterproof smokeless and sulfur-free firing cable and a preparation method thereof, belonging to the field of environment-friendly pyrotechnic compositions.
Background
The emergence of firecrackers dates back to the south-north dynasty, fireworks are born in the down dynasty, and the history of more than one thousand years has become a part of the traditional culture of Chinese nationality today. People are used to increase the festival atmosphere by igniting fireworks and crackers during festive festivals. However, with the development of society, the "forbidden orders" appear in various big cities in recent years, and festive smells are getting lighter and lighter. The 'forbidden' is not only because the fireworks and crackers are set off to cause the hidden danger of fire hazard in dense urban groups, but also more importantly, a large amount of smoke and harmful gas are generated when the fireworks and crackers are set off, and the residual dust is much after the fireworks and crackers are set off, so that the environmental pollution is caused and the health of human is also endangered.
The lead is the first step of igniting fireworks and crackers, and common lead agents contain potassium perchlorate, potassium chlorate, sulfur and other components, and can generate a large amount of smoke to pollute air during combustion. While the harmful residues of combustion also contaminate the soil and water sources. (Songjiafang firework smokeless lead medicament composition: China, 200810143002.0.[ P ].2009-07-15.) proposes that the smoke generated by the medicament composition prepared by using ammonium perchlorate and single-double-base powder is less than 30% of that of the existing medicament, and the medicament composition has no sulfur element in the components. However, the presence of halogen chloride in ammonium perchlorate does not meet the environmental theme advocated today and the presence of ammonium perchlorate compromises the moisture resistance of the formulation. (Wujunhe smokeless fireworks: China, 90105447.X. [ P ].1991-08-28) proposes that nitrocotton and potassium perchlorate are adopted to prepare a medicament composition, and the prepared series of smokeless fireworks products have the advantages of no smoke generation, aromatic smell and the like when being set off. Also, the existence of potassium perchlorate in the patent not only introduces halogen but also reduces the moisture resistance of fireworks produced thereby. (Li Shuyun. environmental protection fireworks propellant: China, 21310413863.7.[ P ].2013.09.12.) the fireworks propellant is prepared by adopting rare earth, perchloric acid and aluminum-magnesium alloy, the environmental protection fireworks have the advantages of good environmental protection, low hygroscopicity and long quality guarantee period, but perchlorate is also used for preparation, and the perchlorate can generate halogen elements in the preparation and use processes, thus being not in line with the advocated halogen-free chemical industry. And the presence of rare earths also increases the manufacturing costs of the fireworks.
For the purpose of environmental protection, we propose a preparation method of the smokeless sulfur-free lead-acid medicine.
Meanwhile, the smooth ignition of the lead is the primary requirement for setting off the fireworks and crackers, and the condition that the lead is easy to be unfired in rainy and humid weather or in water is known to influence the smooth setting off of the fireworks and crackers. Therefore, water resistance is an indispensable characteristic of the firing cable.
