Problems solved by technology

[0004] The inventors of the present invention have repeatedly studied and screened the chemical raw materials that can be used as fireworks medicaments, hoping to overcome the shortcoming of the existing colorful luminous stars burning and flashing in the air, and the shortcoming of the stars bursting in a single shape, and provide a non-hygroscopic, It has good stability and can delay the burning and flashing time of light-colored stars in the air, so that the viewing effect is better, and the composition compatibility and processing technology of the existing light-colored stars are not changed. The time-delay with low sensitivity of mixed drugs and high safety factor Firework Potion

Embodiment 1

[0016] The formula of the red light firework potion is:

[0017] Potassium perchlorate 40% by weight, strontium carbonate 16% by weight, phenolic resin powder 7% by weight;

[0018] Magnesium aluminum alloy powder 14% by weight, polyvinyl chloride 3% by weight, superpower powder 3% by weight;

[0019] Dicyandiamide powder 15-25% by weight;

[0020] The above-mentioned drug raw materials are mixed evenly, processed according to the conventional method for processing fireworks medicaments, adding an appropriate amount of water as a diluting solvent, stirring and granulating to prepare the firework medicament red light star formed by using the present invention as a flame retardant.

Embodiment 2

[0022] The formula of the green light firework potion is:

[0023] Potassium perchlorate 16% by weight Barium nitrate 38% by weight Magnesium aluminum alloy powder 14% by weight;

Abstract

The invention discloses an application of a flame retardant dicyandiamide in a pyrotechnic composition. 5-30% of 100 mesh or above powdery dicyandiamide obtained by crushing is added to the pyrotechnic composition, water is used as a dilution solvent, a colored luminescent aster capable of reducing the combustion rate and prolonging the flashing time is prepared through a routine bright bead processing method, and the pattern of the bursting flower of the colored luminescent aster in air can be changed; and the pyrotechnic composition obtained by using the dicyandiamide as a flame retardant without changing the composition compatibility and the processing technology of existing pyrotechnic composition mixtures has the advantages of low sensitivity, high safety coefficient, no moisture absorption and good stability, and can be widely used in photochromic pyrotechnic compositions of various firework products.

Description

technical field [0001] The invention belongs to the technical field of fireworks medicine, and more specifically relates to a firework medicine composition which uses dicyandiamide as a flame retardant in the firework medicine, thereby delaying the flashing time of colored luminous stars burning in the air. Background technique [0002] Fireworks are traditional handicrafts in my country with a long history. They are unique in production technology, exquisite in manufacture and colorful in color, especially firework bombs, potted flowers and other fireworks products. They not only have various varieties and new structures, but also show people a wonderful This kind of beauty, which is colorful, varied and colorful, adds to the festive and harmonious atmosphere. These spectacular shapes and vivid scenes are all unique effects produced by fireworks, but this fairyland-like beauty is only fleeting in the air, and people who watch it always want to keep the good time. I think th...
