Abstract

The invention relates to a colored light cold firework powder and a preparation method thereof, and belongs to the technical field of civil entertainment fireworks. The preparation method comprises the following steps: weighing nitrocellulose, dicyandiamide, liquid fluororubber, titanium hydride powder and colored rare earth photoluminescence powder; dividing the liquid fluororubber into two parts, wherein the first part is 0.1-0.5% of the total mass of the titanium hydride powder and the colored rare earth photoluminescence powder, and the rest is the second part; mixing the weighed titaniumhydride powder and colored rare earth photoluminescence powder, dropwise adding the first part of liquid fluororubber, kneading, sieving and drying to obtain luminescent granulated powder; and mixingthe nitrocellulose, dicyandiamide and the luminescent granulated powder, dropwise adding the second part of liquid fluororubber, granulating, and drying to obtain the colored light cold firework powder. The colored light cold firework powder provided by the invention is low in cost of raw materials required for preparation, rich in color during setting off, and green and environment-friendly in setting off process.

Description

technical field [0001] The invention relates to a colored light cold smoke flower medicament and a preparation method thereof, belonging to the technical field of civil entertainment pyrotechnics. Background technique [0002] Fireworks have a history of thousands of years in our country, and they have been continuously developed from generation to generation. Setting off fireworks has long been an important way to exaggerate the festive atmosphere during festivals and major celebrations. As we all know, when the traditional fireworks are set off, they will release a pungent smell and produce a large amount of dust, which seriously pollutes the environment. This also makes the country enforce bans and restrictions to protect the environment. [0003] Cold fireworks, as an environmentally friendly fireworks product, are being widely used in large-scale fireworks shows, wedding celebrations and other occasions, and they have become a new favorite for their gorgeous viewing ef...
