Description
Technical Field
The invention relates to a bright flame type smokeless and sulfur-free firecracker and firecracker nitrate medicament and a preparation method thereof, and belongs to the field of environment-friendly pyrotechnic compositions.
Background
Fireworks and crackers are used in great amount and have been popular for a long time in various festivals and celebrations in China. In recent years, due to the continuous increase of consumption, the lack of environmental awareness, the proliferation of manufacturers and the like, the setting off of fireworks and crackers causes serious environmental problems and also brings serious influence on human health.
As is well known, the main components of the prior pyrotechnic compositions are potassium nitrate, sulfur and charcoal, and some pyrotechnic compositions also contain potassium perchlorate, potassium chlorate, even metal powder and the like. The burning off of the gas can generate carbon oxide, nitrogen oxide, sulfur dioxide and dust of metal oxide, which seriously damages the respiratory system, nervous system and the like of human beings and causes irreversible damage to human bodies. In some specific occasions, such as festive events and festival celebrations, the used fireworks and crackers are often required to have high brightness so as to achieve the expected setting off effect. However, in recent years, the number of papers and patents in this aspect is small, and there are literature reports, and the disadvantages thereof are also obvious. The Wangxian and Guojiangbiao are prepared by adding a brightening agent, a flame retardant and an emitting powder into pyrotechnic compositions to mix, so that the stability of the pyrotechnic compositions is increased, and the brightening is more bright during burning (CN201811508314.7), but the addition amount of glutinous rice flour is extremely difficult to control, too much pyrotechnic compositions are adhered together, too little pyrotechnic compositions are dispersed too much, a desired fountain or bright bead effect cannot be formed, and the control on experimental conditions is very difficult; moreover, the bright bead commonly adopted in the pyrotechnic composition is not popular with manufacturers due to unsafe factors of drying and the like, and an intelligent device for drying the bright bead of the fireworks and crackers is designed by Tan Yui and Wangselian, so that the safety problem (CN201220082853.0) which possibly occurs in the process of drying the bright bead is effectively solved, but the manufacturing cost of the fireworks and crackers is greatly increased, and the finished fireworks and crackers are expensive and cannot be accepted by consumers.
On the premise of ensuring that the fireworks and crackers are continuously used by people, the environmental pollution and the harm to the human body caused by setting off are reduced, the same setting off effect is achieved by reducing the using amount of the firecracker and firecracker firework powder, the brightness of the fireworks and crackers can be effectively improved, the use of various occasions is met, the requirements for efficient setting off and smokeless and sulfur-free setting off of the firecracker and firecracker are met, and the direction is pointed out for the development of the firework and firecracker industry. Therefore, the flame bright type smokeless and sulfur-free firecracker nitro-compound and the preparation method thereof have great social and practical significance.
Disclosure of Invention
The invention provides a bright flame type smokeless and sulfur-free firecracker nitrate medicament and a preparation method thereof, aiming at solving the problem of smoke pollution after the existing firecracker nitrate medicament is set off and realizing the same or even more excellent setting-off effect by reducing the dosage.
The purpose of the invention is realized by the following technical scheme.
A flame bright type smokeless and sulfur-free firecracker and firecracker nitrate medicament comprises the following components in percentage by mass:
the nitrogen content of the nitrated bamboo cellulose in the components is 12 to 12.5 percent;
a preparation method of a flame bright type smokeless and sulfur-free firecracker nitrate medicament comprises the following specific steps:

step two, dividing the nitrated bamboo cellulose powder weighed in the step one into A, B groups according to the mass ratio of (1-5) to (10), dissolving the nitrated bamboo cellulose powder of the group A in ethyl acetate according to the mass ratio of 1:10, and stirring for 2-3 hours under the ultrasonic dispersion condition; then, continuously adding the dicyandiamide and the 4-nitrotriphenylamine weighed in the step one under the stirring state, and uniformly stirring to obtain a mixed solution of the nitrobamboo cellulose;
step three, adding the passivated hexogen powder and the titanium deuteride powder weighed in the step one and the B group of nitrated bamboo cellulose obtained in the step two into the nitrated bamboo cellulose mixed sol obtained in the step two under the stirring and ultrasonic dispersion states, and uniformly mixing; adding the calcium metasilicate powder and the calcium glycinate complex powder weighed in the step one, and stirring for 2-3 hours; then adding the methyl silicone oil weighed in the step one, and uniformly mixing; then kneading until the mixture is uniform and conglobate with moderate hardness;
fourthly, granulating the uniform micelle-shaped substance with moderate hardness obtained in the third step by using a double-screw granulator, airing the uniform micelle-shaped substance in a cool and ventilated place to be half-dry, and transferring the uniform micelle-shaped substance to a blast oven at the temperature of 80-90 ℃ for drying for 2-3 hours to obtain a bright flame type smokeless and sulfur-free firecracker nitrate medicament crude product;
and step five, crushing the crude product of the bright flame type smokeless and sulfur-free firecracker and firecracker are evenly.
The method for judging the moderate hardness comprises the following steps: after the micelle-shaped objects are extruded to pass through a 20-mesh copper sieve, the micelle-shaped objects are in a continuous thin strip shape, are not adhered with each other and have certain plasticity and tensile strength;

step two, dividing the nitrated bamboo cellulose powder weighed in the step one into A, B groups according to the mass ratio of (1-5) to (10), dissolving the nitrated bamboo cellulose powder of the group A in ethyl acetate according to the mass ratio of 1:10, and stirring for 2-3 hours under the ultrasonic dispersion condition; then, continuously adding the dicyandiamide and the 4-nitrotriphenylamine weighed in the step one under the stirring state, and uniformly stirring to obtain a mixed solution of the nitrobamboo cellulose;
step three, adding the passivated hexogen powder and the titanium deuteride powder weighed in the step one and the B group of nitrated bamboo cellulose obtained in the step two into the nitrated bamboo cellulose mixed sol obtained in the step two under the stirring and ultrasonic dispersion states, and uniformly mixing; adding the calcium metasilicate powder and the calcium glycinate complex powder weighed in the step one, and stirring for 2-3 hours; then adding the methyl silicone oil weighed in the step one, and uniformly mixing; then kneading until the mixture is uniform and conglobate with moderate hardness;
fourthly, granulating the uniform micelle-shaped substance with moderate hardness obtained in the third step by using a double-screw granulator, airing the uniform micelle-shaped substance in a cool and ventilated place to be half-dry, and transferring the uniform micelle-shaped substance to a blast oven at the temperature of 80-90 ℃ for drying for 2-3 hours to obtain a bright flame type smokeless and sulfur-free firecracker nitrate medicament crude product;
step five, crushing the crude product of the bright flame type smokeless and sulfur-free firecracker and firecracker are small in;
the method for judging the moderate hardness comprises the following steps: after the micelle is extruded to pass through a 20-mesh copper sieve, the micelle is in a continuous thin strip shape, is not adhered with each other, and has certain plasticity and tensile strength.
