Novel oxidant for fireworks and preparation method thereof

Abstract

The invention provides a novel oxidant for fireworks and a preparation method thereof in order to improve the performance price ratio of a fireworks powder oxidant. The novel oxidant for the fireworks is characterized in by comprises the following raw materials in part by weight: 5 to 7 parts of barium nitrate, 5 to 6 parts of potassium hyperchlorate, 3 to 10 parts of density degree regulator and 1 to 5 part of catalyst. The preparation method of the novel oxidant for the fireworks is characterized by comprising the following steps of: crushing the raw materials into 120 to 350 meshes respectively; and uniformly mixing the raw materials according to the proportions of the raw materials to obtain a special oxidant product. For a product produced by using the special oxidant, the bursting strength, the cost price and the proportion of the raw materials are close to those of potassium chlorate, the safety performance is close to that of the potassium hyperchlorate, and the performance price ratio of the product is significantly improved, so the product is highly praised and appreciated by users.

Description

technical field [0001] The invention relates to an oxidizing agent for making fireworks and firecracker gunpowder and a preparation method thereof. Background technique [0002] Since the country banned the use of potassium chlorate in firecrackers and fireworks, various oxidants to replace potassium chlorate have sprung up, but the firecracker industry is a high-risk and low-reward enterprise. Material selection is the key. Potassium perchlorate has good safety performance, but the high price is uneconomical. Therefore The main raw materials are all inseparable from barium nitrate, but when manufacturers use barium nitrate as an oxidant, they find that it has the following deficiencies: 1. Barium nitrate has a slight moisture absorption property, and the firecrackers produced will deteriorate within 3-5 months. 2. The melting point of barium nitrate is high, the time from combustion to explosion is long, and the sound quality is poor. 3. Barite, the main material of barium...

[0002] Since the country banned the use of potassium chlorate in firecrackers and fireworks, various oxidants to replace potassium chlorate have sprung up, but the firecracker industry is a high-risk and low-reward enterprise. Material selection is the key. Potassium perchlorate has good safety performance, but the high price is uneconomical. Therefore The main raw materials are inseparable from barium nitrate, but when the manufacturer uses barium nitrate as an oxidant, they find that it has the following deficiencies in performance: 1. Barium nitrate has micro-moisture absorption properties, and the firecrackers produced will deteriorate within 3-5 months

2. The melting point of barium nitrate is high, the time from combustion to explosion is long, and the sound quality is poor

3. Barite, the main material of barium nitrate, has a large specificity, less barrels, and increases product costs. The fireworks industry is unwilling to use it; in order to solve the problem of large specificity, some technical solutions are mixed with light calcium carbonate, but light calcium carbonate Calcium has a high melting point and has a flame retardant effect, which affects the burning speed
