Firework box-like star gunpowder

Abstract

The invention discloses firework box-like star gunpowder. The firework box-like star gunpowder is prepared from the following materials in percentage by weight: 10-20% of potassium perchlorate, 45-70%of basic cupric carbonate, 10-15% of natural resin, 5-10% of oils and 5-7% of desensitizing agents. A formula of the firework box-like star gunpowder disclosed by the invention does not contain strong antioxidants such as potassium chlorate and sulfur; the firework box-like star gunpowder is pollution-free and high in safety; a dreamy sea blue box-like planet effect is produced during discharging; the color is beautiful; the form is special; in addition, through the addition of different proportions of the desensitizing agent, the discharging speed of fireworks can be controlled; the discharging time can be delayed or shortened; the firework box-like star gunpowder can be better adapted to the market requirements; and a preparation method is simple, easy to start and convenient for production.

Description

technical field [0001] The invention relates to a firecracker, in particular to a firecracker box-shaped star medicine, which belongs to the technical field of fireworks. Background technique [0002] With the improvement of people's living standards and the continuous development of science and technology, the safety, entertainment and technical requirements of fireworks used in festivals and other occasions are also getting higher and higher; in the prior art, fireworks mainly use potassium chlorate, It is prepared from raw materials such as sulfur and iron slag. Potassium chlorate is the most commonly used oxidant in the production of fireworks and firecrackers. It is a strong oxidant. Its thermal decomposition process is an exothermic reaction with low decomposition temperature. Chemical characteristics, in addition to the uneasy factors in the process of preparation, processing, storage and transportation, the unreasonable proportion of each component often causes the p...

Problems solved by technology

[0002] With the improvement of people's living standards and the continuous development of science and technology, the safety, entertainment and technical requirements of fireworks used in festivals and other occasions are also getting higher and higher; in the prior art, fireworks mainly use potassium chlorate, It is prepared from raw materials such as sulfur and iron slag. Potassium chlorate is the most commonly used oxidant in the production of fireworks and firecrackers. It is a strong oxidant. Its thermal decomposition process is an exothermic reaction with low decomposition temperature. Chemical characteristics, in addition to the uneasy factors in the process of preparation, processing, storage and transportation, the unreasonable proportion of each component often causes the products after combustion to block the holes of the fireworks during discharge, which not only affects the discharge of fireworks, but also easily causes explosions. , causing bodily harm to consumers and the surrounding masses; Chinese patent application number: 201310430115. 4-6 parts of sodium particles, 2-5 parts of aluminum powder, 4-6 parts of magnesium foil, 3-5 parts of potassium permanganate, 2-3 parts of adhesive, 5-8 parts of oxidizing agent and 3-6 parts of barium nitrate part, 16-20 parts of adhesive; described adhesive is any one in epoxy resin, resorcinol resin or styrene resin; adopt formula of the present invention, production process is convenient, safe and reliable, production High efficiency and low cost. When the product is set off, its emission trajectory is uniform, and the single trajectory is in an upward arc shape, and the overall shape is in the shape of a water drop. Its color is gorgeous and the sound is crisp and loud; After that, it pollutes the environment more; therefore, in order to solve the above problems, a new type of fireworks with good safety and various postures is designed.
