Description
Technical Field
The invention relates to a color light cold firework powder and a preparation method thereof, belonging to the technical field of civil entertainment fireworks.
Background
Fireworks have a history of thousands of years in China and are continuously developed in the inheritance of one generation and another. Setting off fireworks has long become an important way to render happy and happy atmosphere in holidays and major celebrations. As is known, the traditional firework powder releases pungent smell when being set off, generates a large amount of dust, and seriously pollutes the environment, so that the state enforces banning and banning orders to protect the environment.
The cold fireworks, as an environment-friendly firework product, are being widely applied to various occasions such as large fireworks evening party, wedding celebration and the like, and become a new favorite due to gorgeous ornamental effect and artistic modeling presented when the cold fireworks are set off. However, the current cold fireworks usually use low ignition point metal as raw material, and the colors presented are single, so that the increasing ornamental requirements of the public can not be met. For colorful cold light fireworks, there are some patents describing them. Patent CN103121886A discloses a colorful cold firework agent and a cold firework manufacturing method, and the agent comprises the following components: 20-30% of ammonium perchlorate, 20-30% of nitrocotton, 30-35% of silver titanium powder, 15-20% of photoluminescent material and 5-10% of fluororubber. However, the photoluminescence material can not achieve stable multicolor effect, and the white light has more variegated colors when the photoluminescence material is set off. Patent CN103030483A discloses a bright green cold firework explosive and a preparation method thereof, wherein the explosive comprises the following components in percentage by weight: 25-40% of boron powder, 5-15% of magnesium aluminum alloy powder, 6-12% of titanium powder, 8-15% of barium nitrate, 6-10% of 52# chlorinated paraffin, 15-20% of nitrocotton and 15-20% of ammonium perchlorate, and the preparation method of the medicament comprises the steps of fuel mixing, fuel granulation, fuel granule drying, medicament mixing and the like. The bright green cold firework powder prepared by the method is difficult to achieve complete and uniform mixing in the fuel mixing process, and the illusion-color effect is not ideal in the setting-off process. Patent CN109913697A discloses a metal alloy powder for multi-wavelength cold light fireworks and a preparation method thereof, the method takes metal zirconium as a main body, other metal combustible agents are added to prepare the metal alloy combustible agent, and the aim of coloring the cold light fireworks is achieved by adjusting the radiation wave band when the powder is burnt. Therefore, the cold firework powder which is rich in color, green and environment-friendly becomes an urgent need in the current firework market.
