Description
Technical Field
The invention relates to a preparation method of a firecracker medicament with high explosive sound, and belongs to the field of material processing and preparation and pyrotechnic composition technology intersection.
Background
The high-explosive-sound firecracker medicament can be widely applied to the fields of special-effect scenes of movie and television shooting and the like. The traditional formula of the firecracker medicament with high explosive sound is based on black powder components, potassium chlorate, sulfur and the like are adopted, acid gases such as sulfur dioxide and the like and black particle floating materials are generated during setting off, on one hand, environmental pollution is caused, on the other hand, the setting off effect is influenced by smoke formed, and the main raw material of potassium chlorate is completely forbidden. Currently, the formulas of the firecracker medicaments with high explosive sound which are used in the market are potassium perchlorate series formulas. The potassium perchlorate series formula still needs to use sulfur, and even increases the dosage of sulfur. This aggravates the generation of sulfur dioxide gas. Moreover, the hygroscopicity of potassium perchlorate also hides the stability problem, and explosion caused by hygroscopicity in production and preparation is easy to cause. With the strengthening of the national green industry management and the execution of forbidden orders, the harm of the traditional formula to the environment does not adapt to the green development requirement of the modern society. In recent years, the aim of gradually increasing the sound of the firecracker from low to low when the firecracker is set off is achieved by reducing the amount and the volume of the fire powder of the single firecracker at the lead end of the firecracker (CN 200610200143.2); shenchangsheng achieves a good sound effect by using an analog electronic firecracker sound integrated circuit chip as a sound source and using a high-power audio power amplifying circuit module to drive more than two high-power loudspeakers (CN 201420544882.3); the Hujun and Zhao are programmed with fireworks in different forms, the laser is controlled by the program to emit laser which can not be in color, different height and different position to form laser with different patterns, the shape and sound of various fireworks are simulated, a volume adjusting button, a distance adjusting button, a color adjusting button, a sound simulating adjusting button and a color system selecting module are arranged to simulate the firing effect of fireworks and crackers, and the required high popping effect is achieved through the volume adjusting button (CN201711410584. X). However, the disadvantages of the methods are very remarkable, the preparation method is complex, and the condition control is difficult; the simulation equipment is complex, expensive, too high in cost once used, cannot be accepted by the masses, cannot bring visual and auditory enjoyment to people, and has low market demand. The invention aims to carry out technical innovation by utilizing a smokeless nitrated bamboo cellulose series formula to obtain a preparation method of a novel high-explosive-sound firecracker medicament.
