Safe and sulfur-free firework bursting powder and propelling powder and preparing method thereof

Abstract

The invention discloses safe and sulfur-free firework bursting powder and propelling powder and a preparing method thereof, and relates to the technical field of fireworks. The firework bursting powder is prepared from, by weight, 15-35 parts of carbon powder, 5-60 parts of potassium perchlorate and 15-70 parts of potassium nitrate. The firework propelling powder is prepared from, by weight,15-35parts of carbon powder, 5-60 parts of potassium perchlorate, 15-70 parts of potassium nitrate, 5-10 parts of adhesive and a proper amount of solvent. The firework bursting powder and propelling powderdo not contain sulfur, metal, benzene or the like, have no toxicity, reduce the air pollution, generate less smoke, have zero percussion sensitivity and friction sensitivity, guarantee safety and environmental protection, have a low moisture absorption rate and stable performance, reduce the ignition point properly, have flammability, high safety performance and propelling performance, do not easily cause barrel blasting, and reduce the production cost; the preparing method of the sulfur-free firework bursting powder and propelling powder is simple and safe.

Description

technical field [0001] The invention relates to the technical field of fireworks and firecrackers, in particular to a safe sulfur-free fireworks explosive, a propellant and a preparation method thereof. Background technique [0002] Existing firework detonator and propellant are to use black powder, promptly take charcoal as combustible, potassium nitrate as oxidizer, sulfur as the pyrotechnic powder that reducing agent is made, has another name called military industry salt and military industry powder. It has the following deficiencies: first, combustion will produce a large amount of sulfur dioxide and sulfide, which will pollute the environment and cause large smog; secondly, the mechanical sensitivity of black powder is relatively high, and it is easy to catch fire or explode when subjected to strong impact or friction , low safety during production and transportation, and great danger to human life and property; third, its preparation process is complicated, and it nee...

AI Technical Summary

Problems solved by technology

It has the following deficiencies: first, combustion will produce a large amount of sulfur dioxide and sulfide, which will pollute the environment and cause large smog; secondly, the mechanical sensitivity of black powder is relatively high, and it is easy to catch fire or explode when subjected to strong impact or friction , low safety during production and transportation, and great danger to human life and property; third, its preparation process is complicated, and it needs to go through ball milling, mixing, oil pressure, high temperature, polishing and other processes

However, in some existing improved technologies, some propellants have unsatisfactory launch power, some have too strong launch force and poor stability, and some use metal-based combustibles for improvement, which is prone to explosion and cause safety accidents, and some The material cost and production cost are too high. All in all, the current improved products or newly developed products have limited their promotion and application in actual production due to serious defects. Some invention patents are still on paper and have no substance. sexual use in production
