Abstract

The invention discloses a sulfur-free blue light agent, and belongs to a composition emitting blue light during combustion. The sulfur-free blue light agent is prepared from, by weight, 20-30 parts ofcopper oxide, 30-40 parts of chlorinated paraffin, 30-40 parts of polyvinyl chloride paste resin, 5-10 parts of paint sheets and 10-15 parts of polyurethane resin. The invention further discloses a preparation method of the sulfur-free blue light agent. According to the blue light agent, sulfur is not added, the problem of environmental pollution is solved, and the blue light agent has an environment-friendly effect. Compared with the prior art, the method has the following advantages: resources are saved, the cost is reduced, huge economic benefits are obtained, and the prepared blue light agent is deep in blue light color, high in purity, obvious in brightness and enhanced in waterproof and moisture-proof performance in storage.

Description

technical field [0001] The invention belongs to a composition that emits blue light when burned, and in particular relates to a sulfur-free blue light agent and a preparation method. Background technique [0002] Fireworks are pyrotechnic entertainment products that use pyrotechnic powder to produce sound, light, color and other effects through combustion or explosion for viewing. The formula of blue light agent used by major fireworks manufacturers in the manufacture of blue light fireworks is composed of copper oxide, hexachlorobenzene, sulfur, potassium perchlorate, and phenolic resin. Among them, the blue effect produced by combustion of copper oxide and hexachlorobenzene is the best. However, because hexachlorobenzene is highly toxic after burning, and hexachlorobenzene is a banned product for export in my country, the current Blu-ray formula used by manufacturers prohibits hexachlorobenzene, but adds sulfur. However, sulfur will produce a large amount of sulfur dioxi...
