preparation example Construction

[0019] The preparation method of the smokeless and scented luminescent fireworks agent of the present invention is simple, safe and efficient, and the components are uniformly mixed to obtain the finished product.

[0020] The smokeless and scented luminescent fireworks medicament provided by the invention is widely used in fireworks and firecrackers. For example, after the medicament is molded and packaged, it can be used as cake cold fireworks, hand-held luminescent fireworks, wedding luminescent fireworks, etc., with good discharge effect and safe use. .

Embodiment 1

[0023] Apple-flavored smokeless and scented cold light fireworks agent: Weigh 85 parts by mass of nitrocellulose with a nitration degree of 190mL / g, 1 part by mass of diphenylamine, 2 parts by mass of ferrocene, 3 parts by mass of apple essence, and a particle size of 120-140 The target titanium sponge powder is 9 parts by mass, which is obtained by mixing the above-mentioned raw materials evenly.

[0024] Make the above-mentioned medicament into a 16mm-diameter powder column, and put it into the set-off props. When set off, the sparks are sprayed upwards, no smoke, no pungent smell, the gas after burning has a faint apple fragrance, and no residue falls. The flame is suitable for burning on the cake to increase the atmosphere of the celebration.

Embodiment 2

[0026] Rose-flavored smokeless and scented luminescent fireworks agent: Weigh 70 parts by mass of nitrocellulose with a nitration degree of 210mL / g, 1 part by mass of No. 1 intermediate, 3 parts by mass of ferrocene, and 5 parts by mass of rose essence, Mesh ~ 140 mesh titanium metal powder 21 parts by mass, uniformly mix the above raw materials to obtain.

[0027] The above medicament is made into a 25 mm diameter powder column, which is loaded into the set-off props. When set off, the set-off height is 2.5m to 3m, which can be placed on both sides of the red carpet. When set off, it is smokeless, odorless, and slag-free, and produces rose-scented gas. The wedding adds a romantic atmosphere, and the flames are gorgeous and colorful.

Abstract

The invention discloses smokeless and fragrant stage fireworks powder, and belongs to the field of fireworks and firecrackers. The invention aims to provide stage fireworks powder which has the advantages of little and even no combustion smoke, strong jet power, full sparks and fragrant smell. The stage fireworks powder is prepared from the following components in parts by mass: 13-91 parts of nitrocellulose, 0.2-5 parts of ferrocene, 0.5-2.5 parts of stabilizing agent, 0.5-5 parts of essence and 8-80 parts of titanium powder. According to the stage fireworks powder provided by the invention,by adjusting the proportion of the nitrocellulose, the stabilizing agent, the ferrocene, the essence and the titanium powder, smoke is avoided after the stage fireworks powder is set off, and the spark jetting is stable and full while the temperature is low; after combustion, irritant ammonia smell is not generated, and the gas generated after the powder combustion can emit various fragrances to comfort people and adjust the atmosphere; the stage fireworks powder provided by the invention is widely applied to the field of fireworks and firecrackers and deserves popularization.

Description

technical field [0001] The invention belongs to the field of fireworks and firecrackers, and in particular relates to a smokeless and fragrant luminescent fireworks medicament. Background technique [0002] Cold light fireworks are also called cold fireworks. The ignition point of ordinary fireworks is between 500°C and 800°C, and it is easy to cause harm to the human body when burning. However, the ignition point of cold fireworks is between 60°C and 80°C, and the external temperature is 30°C to 50°C, which is harmless to the human body. Cold fireworks are suitable for indoor and outdoor discharge, with high brightness, less smoke and less pollution during discharge, which can strongly enhance the atmosphere of the scene. Cold light fireworks products with various shapes and designs are suitable for setting off in different places, such as outdoor dragon dance performances and indoor stage performances. [0003] At present, the medicament of commercially available luminesc...
