Problems solved by technology

[0002] The pyrotechnic powder in fireworks products is a complex mixture, the physical and chemical properties of most of the ingredients are very unstable, and they will change slowly or violently under certain external conditions, which may reduce the discharge effect of the product, or cause combustion and explosion. Accidents, therefore, when the safety and environmental protection requirements for fireworks products are strengthened all over the world, the safety of the pyrotechnic powder of fireworks products seriously restricts the development of the industry

Embodiment 1

[0021] Example 1 : when the pyrotechnic powder of the present invention was used as a powdery colored flower spraying agent, each component and the ratio of parts formulated in the following table were pulverized, screened, uniformly mixed, and then prepared into a powdery agent, which was used for After the spraying product is set off, it shows red, blue, green, yellow, purple fireworks spraying silver or golden flowers. Take 20 grams of pyrotechnic powder and test it through experiments. The impact sensitivity is about 40%, and the friction sensitivity is about 5%. 12 meters There is no burning or explosion in the drop test, the moisture absorption rate is ≤0.8%, and the stability test results at 75°C are all "stable".

Embodiment 2

[0024] Example 2: When the pyrotechnic agent of the present invention is used as a powdery colored flame medicament, each component is pulverized, screened, and evenly mixed according to the components and the ratio of parts formulated in the following table, and then prepared into a powdered medicament, which is used in fireworks products Red, blue, green, yellow, and purple flames appeared after discharge. Take 20 grams of pyrotechnic powder and test it through experiments. The impact sensitivity is about 40%, the friction sensitivity is about 5%, and there is no combustion or explosion in the 12-meter drop test. ≤0.8%, the stability test results at 75°C are all "stable".

Abstract

A safe environment-friendly novel pyrotechnic composition is used as a powdery colorful flower-forming spray composition, and comprises the compositions in parts by weight: 20-50 parts of a high-energy oxidizing agent, 30-60 parts of nitrocellulose, 1-15 parts of a colouring agent, 1-15 parts of a combustible effect agent, 1-10 parts of an adhesive, and 1-10 parts of a stabilizing agent. A preparation technology for the novel pyrotechnic composition is simple, the pyrotechnic composition prepared by employing the above formula is relatively low in friction sensitivity and impact sensitivity, far higher in chemical stability and safety than those of other pyrotechnic compositions, slightly smoky and environment-friendly after being combusted, and is widely applicable to various pyrotechnic composition products.

Description

technical field [0001] The invention relates to the preparation technology of pyrotechnic agent composition in fireworks products. Background technique [0002] The pyrotechnic powder in fireworks products is a complex mixture, the physical and chemical properties of most of the ingredients are very unstable, and they will change slowly or violently under certain external conditions, which may reduce the discharge effect of the product, or cause combustion and explosion. Accidents, therefore, when the safety and environmental protection requirements for fireworks products are strengthened all over the world, the safety of the pyrotechnic powder of fireworks products seriously restricts the development of the industry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pyrotechnic composition that is safe, environmentally friendly and highly stable. [0004] In order to achieve the above object, the present inven...
