Problems solved by technology

Its discharge will produce chloride and sulfide smoke and metal oxide dust, which will affect human health and cause certain pollution to the environment; When the color is not bright or there are residues, it will arouse the disgust of the audience, and the effect of celebration and the purpose of adding color will not be achieved.
Moreover, the lack of effective formulas and preparation methods for magenta cold smoke flower medicaments on the market is a weak area for the preparation of cold smoke flower medicaments, and also limits the application diversity of cold smoke flower medicaments

Abstract

The invention relates to a smokeless sulfur-free magenta indoor setting-off type cold firework agent and a preparation method thereof, and belongs to the field of environment-friendly pyrotechnic compositions. The preparation method comprises the steps: weighing the modified alloy type flame retardant, the nitrocellulose, the aluminum stearate and the melamine; adding the nitrified bamboo cellulose into ethyl acetate, stirring and adding the aluminum stearate and the melamine to obtain a solution A; and adding the modified magenta flame coloring agent into the solution A, stirring, drying andkneading to form uniform micelles with moderate hardness, granulating, drying to obtain a smoke-free sulfur-free magenta indoor setting-off type cold firework agent crude product, crushing and sievingto obtain the smoke-free sulfur-free magenta indoor setting-off type cold firework agent with uniform particles. The method is safe and reliable and no toxic or harmful smoke is generated; the preparation method has the advantages of simple process, few steps and no emission of three wastes in the production process.

Description

technical field [0001] The invention relates to a smokeless and sulfur-free magenta indoor discharge type cold smoke flower agent and a preparation method thereof, belonging to the field of environment-friendly pyrotechnic agents. Background technique [0002] The development of cold fireworks marks that the fireworks industry is moving towards a new stage. Its advantages such as environmental protection and low discharge temperature are new trends in the future development of the fireworks industry and have strong competitiveness in the market. [0003] Patent CN108218644A discloses a smokeless and scented luminescent fireworks agent. The components of the luminescent fireworks agent include: nitrocellulose, ferrocene, stabilizer, essence, and titanium powder. By adjusting the ratio of each component, the luminescent fireworks agent The ideal eruption effect is achieved, but the color of the luminescent fireworks agent disclosed in this patent is single during the discharge...
