Problems solved by technology

[0003] The technical problem to be solved by the present invention is: Potassium chlorate and potassium perchlorate are used as oxidants in the production of existing fireworks and firecrackers, but potassium chlorate and potassium perchlorate are very sensitive to friction, impact and heat, and fireworks and firecrackers are prone to explosion, which seriously threatens the safety of people's lives and property to provide a new fireworks oxidant that can replace potassium chlorate and potassium perchlorate at the same time, solve the safety problem of explosions caused by excessive drug sensitivity in the production of fireworks, and reduce the production cost of fireworks enterprises and improve economic benefits.

Embodiment 1

[0022] Embodiment 1: This novel firecracker oxidant is mainly formed by barium nitrate and potassium nitrate 1: 2 type nitric acid compound, wraps a layer of dense uniformly on the surface of this nitric acid compound by potassium perchlorate and organic wrapping agent polyacrylic acid The composite film that butyl ester forms, the percentage by weight of its composition of novel fireworks oxidizer is: barium nitrate: potassium nitrate: potassium perchlorate: polybutylacrylate=45%: 42%: 12%: 1%, the novel fireworks oxidizer that makes The moisture absorption rate is within 0.2%-0.8%, and the oxygen content is between 34%-36%.

Embodiment 2

[0023] Embodiment 2: This novel firecracker oxidant is mainly formed by strontium nitrate and potassium nitrate 1: 2 type nitric acid compound, at the surface of this nitric acid compound evenly coated one layer by potassium perchlorate, strontium perchlorate, organic wrap The dense composite film that agent octadecylamine forms, and the weight percent of its composition of this novel fireworks oxidant is: strontium nitrate: potassium nitrate: potassium perchlorate: strontium perchlorate: octadecylamine=40%: 39 %: 10%: 10%: 1%. The novel firecracker oxidant of the present invention can not only replace potassium chlorate and potassium perchlorate, but also replace strontium carbonate, and be used as a red light agent in the production of firecrackers.

Embodiment 3

[0024] Embodiment 3: this novel firecracker oxidant, its main component is the 1: 4 type cupric ammonium nitrate double salt that forms by copper nitrate, ammonium nitrate, has wrapped one deck by high A dense composite film formed of ammonium chlorate and organic wrapping agent polybutyl acrylate. The weight percentage of this novel fireworks oxidant composition is copper nitrate: ammonium nitrate: ammonium perchlorate: polybutylacrylate=25%: 60%: 14%: 1%. The novel firecracker oxidant of the present invention can not only replace potassium chlorate and potassium perchlorate, but also replace cuprous chloride or cuprous oxide, the blue light agent in the production of firecrackers, and be used to produce blue light firework shells, with purer and brighter colors and shorter luminous radius. Larger and longer discharge time, it solves the long-standing problem of impure blue light in the production of fireworks.

Abstract

This new firework oxidant is a multi-element composite composed of two or more azotates and one or several perchlorates, among which perchlorates and organic encapsulation agent uniformly cover on the surface of the complex azotate, forming a layer of compact complex film. This invention resolves the puzzle of azotates' inclination to absorb moisture and insensitivity to explode. Therefore if as a substitute for potassium chlorate and potassium perchlorate simultaneously, it can resolve the security problem during production, cut down production cost and increase profit. Advantages: advanced technology and superior technical performance.

Description

technical field [0001] The invention relates to an oxidizing agent and color light agent in the production of fireworks and firecrackers. Background technique [0002] The production of fireworks has a long history in our country. The invention of gunpowder has laid the foundation for the production of fireworks. For thousands of years, nitrates have been used as oxidants in the production of fireworks, but nitrates have the disadvantages of high moisture absorption rate and insufficient explosion sensitivity. Defect, can not be stored for a long time. The emergence of potassium chlorate and potassium perchlorate brought the production of fireworks into a new stage of development, but the safety accidents that followed were also very prominent, mainly because potassium chlorate was very sensitive to friction, impact and heat. Potassium perchlorate is also highly sensitive to friction and impact when heated. For this reason, the State Council and the Ministry of Public Secur...
