Embodiment 1

[0024] A smokeless and sulfur-free fireworks speed regulator, the mass percentages of its components are as follows:

[0025]

[0026] 25g of pseudoboehmite powder, 25g of basic zinc carbonate powder and 15g of calcium bicarbonate powder are fully stirred and mixed in a dry powder mixer to obtain mixed powder A; in the stirring state, 33g of dicyandiamide and 2g of rosin are sequentially mixed Add it into 170g of ethanol, and stir continuously for 30 minutes to obtain the mixed solution B; under the stirring state, slowly add the mixed solution B to the mixed powder A, after the addition is completed, raise the temperature to 50°C, and continue to stir until the material becomes a uniform mud mass The resulting uniform gelatinous mass with moderate hardness is granulated with a twin-screw granulator, and vacuum-dried at 60°C for 12 hours to obtain the crude product of smokeless and sulfur-free fireworks speed regulator; After the rough product of the smokeless and sulfur-fr...

Embodiment 2

[0028] A smokeless and sulfur-free fireworks speed regulator, the mass percentages of its components are as follows:

[0029]

[0030]

[0031] 560g of pseudo-boehmite powder, 540g of basic zinc carbonate powder and 200g of calcium bicarbonate powder were fully stirred and mixed in a dry powder mixer to obtain mixed powder A; in the stirring state, 600g of dicyandiamide and 100g of rosin were sequentially mixed Add it into 4000g of ethanol, and continue stirring for 45 minutes to obtain a mixed solution B; under stirring, slowly add the mixed solution B to the mixed powder A, after the addition is completed, heat up to 55°C, and continue to stir until the material becomes a uniform mud mass The resulting uniform gelatinous mass with moderate hardness is granulated with a twin-screw granulator, and vacuum-dried at 60°C for 12 hours to obtain the crude product of smokeless and sulfur-free fireworks speed regulator; After the crude product of the smoke-free and sulfur-free ...

Embodiment 3

[0033] A smokeless and sulfur-free fireworks speed regulator, the mass percentages of its components are as follows:

[0034]

[0035] 3kg pseudo-boehmite powder, 3kg basic zinc carbonate powder and 1kg calcium bicarbonate powder were fully stirred and mixed in a dry powder mixer to obtain mixed powder A; under stirring state, 2.5kg dicyandiamide, 0.5kg Add rosin to 15kg of ethanol in turn, and after continuous stirring for 60 minutes, a mixed solution B is obtained; under stirring, slowly add the mixed solution B to the mixed powder A, after the addition is completed, the temperature is raised to 55°C, and the stirring is continued until the material becomes uniform Sludge; the resulting soft and hard moderate uniform micelles are granulated with a twin-screw granulator, and vacuum-dried at 60°C for 12 hours to obtain the crude product of smokeless and sulfur-free fireworks speed regulator; the obtained After the crude product of the smokeless and sulfur-free fireworks spe...

Abstract

The invention relates to a smoke-free and sulfur-free firework speed regulator and a preparation method thereof, and belongs to the field of environment-friendly pyrotechnic compositions. The preparation method comprises the following steps: S1, weighing pseudo-boehmite powder, basic zinc carbonate powder, calcium bicarbonate powder, dicyandiamide and rosin according to a mass ratio in a formula;fully stirring and mixing the pseudo-boehmite powder, the basic zinc carbonate powder and the calcium bicarbonate powder in a dry powder mixer to obtain mixed powder A; sequentially adding dicyandiamide and rosin into ethyl alcohol under stirring to obtain a mixed solution B; slowly adding the mixed solution B into the mixed powder A under stirring, raising the temperature after addition, continuing stirring until the material becomes a mud pie with moderate hardness, granulating and drying the mud pie to obtain a crude smoke-free and sulfur-free firework speed regulator, and carrying out crushing and sieving to obtain the smoke-free and sulfur-free firework speed regulator. According to the method, calcium carbonate powder and magnesium carbonate powder are adopted as main components, thedecomposition product is gas and does not contain sulfur, the process is simple, and no three wastes are discharged in the production process.

Description

technical field [0001] The invention relates to a smokeless and sulfur-free fireworks speed regulator and a preparation method thereof, belonging to the field of environment-friendly pyrotechnics. Background technique [0002] Since ancient times, China has had the tradition of setting off fireworks on festivals. The display of fireworks adds a festive atmosphere to the festival. However, in recent years, due to the continuous growth of consumption, the lack of environmental protection awareness and the impact of the surge of manufacturers, a large number of fireworks have been set off, and the toxic and harmful gases and dust particles produced have a very serious impact on human body functions. Setting off a large number of fireworks in a short period of time will bring great pollution to the environment, and also threaten the safety of people's lives and properties. [0003] Firework speed regulator is an important part of pyrotechnics, which can absorb heat and decompos...
