Blue flashing bead body for manufacturing fireworks

Abstract

The invention discloses a blue flashing bead body for manufacturing fireworks. The blue flashing bead body is characterized by consisting of a blue flashing core, a middle gunpowder packing layer andan ignition gunpowder layer, wherein the blue flashing core is arranged at the center of the bead body; the surface of the blue flashing core is coated with the middle gunpowder packing layer; the outer surface of the middle gunpowder packing layer is coated with the ignition gunpowder layer; after drying, an integral core bead is formed; the blue flashing core takes 30-50% of a blue light agent,25-35% of potassium dichromate, 15-20% of titanium powder, 10-15% of aluminum powder and 5-6% of an adhesion agent in mass percentage as main components; and the blue light agent is a composition of cupric subcarbonate, ammonium dichromate and rare metal materials. The blue flashing bead body is free of moisture absorption, good in stability, bright in color, low in cost and suitable for specification demands of various firework products.

Description

technical field [0001] The invention relates to a colored flame agent widely used in fireworks products, in particular to a blue sparkle bead used in making fireworks. Background technique [0002] At present, the blue flash inner core in the blue flash star used for fireworks such as fireworks shells and potted flowers is usually made of blue light agent copper salt mixed with ammonium perchlorate, sulfur, magnesium powder, paraffin and other agents to form granules. After wrapping the middle-packed medicine and the ignition medicine, the blue flash beads are made. Although it can produce better results, there is a fatal shortcoming, that is, the chemical raw materials used in the blue flash inner core are copper oxide and perchloric acid. Ammonium has strong hygroscopicity and is easy to cause the oxidation of magnesium powder. Therefore, the blue sparkle beads produced have poor stability and the color is very bright when they are set off. Especially in the southern area,...

Problems solved by technology

[0002] At present, the blue flash inner core in the blue flash stars used for fireworks such as fireworks shells and potted flowers is usually made of blue light agent copper salt mixed with ammonium perchlorate, sulfur, magnesium powder, paraffin and other agents to mix and granulate. After wrapping the middle-packed medicine and the ignition medicine, the blue flash beads are made. Although it can produce better results, there is a fatal shortcoming, that is, the chemical raw materials used in the blue flash inner core are copper oxide and perchloric acid. Ammonium has strong hygroscopicity and is easy to cause the oxidation of magnesium powder. Therefore, the blue sparkle beads produced have poor stability and the color is very bright when they are set off. Especially in the southern area, where the air humidity is high and it is the main production area of ​​fireworks, use this A kind of beads with strong hygroscopicity not only seriously affects the quality and discharge effect of fireworks products, but also has high production cost and poor safety performance, so it is not suitable for production
