Embodiment 1

[0015] The raw material composition of this embodiment is: potassium perchlorate 20, barium nitrate 65, single base powder 10, iron oxide 5.

[0016] The preparation method is as follows: passing the above-mentioned raw materials through a 120-mesh sieve respectively, then adding the sifted raw materials into a mixer for mixing and stirring, passing through a 120-mesh sieve, mixing again, and packaging to become a finished product.

Embodiment 2

[0018] The raw material composition of this embodiment is: 55% potassium perchlorate, 40% barium nitrate, 1 base powder, and 4% iron oxide.

[0019] The preparation method is as follows: passing the above-mentioned raw materials through a 100-mesh sieve respectively, adding the sifted raw materials into a mixer for mixing and stirring, passing through a 100-mesh sieve, mixing again, and packaging to obtain a finished product.

Embodiment 3

[0021] The raw material composition of this embodiment is: potassium perchlorate 40, barium nitrate 50, single base powder 2, iron oxide 8.

[0022] The preparation method is as follows: passing the above-mentioned raw materials through a 160-mesh sieve respectively, then adding the sifted raw materials into a mixer for mixing and stirring, passing through a 120-mesh sieve, mixing again, and packaging as a finished product.

Abstract

The invention provides a composite oxidant for fireworks. The composite oxidant consists of the following raw materials in percentage by weight: 20 to 55 percent of potassium perchlorate, 40 to 65 percent of barium nitrate, 1 to 10 percent of monobase powder and 2 to 8 percent of ferric oxide. The composite oxidant for the fireworks has safe performance and low price; the moisture absorption rate is less than 1 percent; the friction sensitivity and the impact sensitivity are zero; and the fireworks produced by the oxidant have the explosion rate and the paper breaking rate of over 98 percent and have safety, stability and long storage time.

Description

technical field [0001] The invention relates to an oxidizing agent, in particular to a fireworks composite oxidizing agent. Background technique [0002] In the fireworks and firecrackers industry, in order to ensure the safety of people’s lives and achieve safe production, the state has ordered to prohibit the use of potassium chlorate in fireworks oxidizers, because of its high friction and impact sensitivity, and both friction and impact coefficients are 100%. There is a high risk of explosion accidents if you are not careful. Potassium peroxate is used as an oxidant for firecrackers, and the cost is too high. How to develop an oxidant with safe operation, good discharge effect and low cost is an urgent and difficult task in the same industry across the country. [0003] Chinese patent such as application number is 03118270.4 (firecracker oxidant) and application number is 200410016899.2 (firecracker safety oxidant) all discloses the firecracker oxidant that replaces exi...
