Application of a flame retardant dicyandiamide in pyrotechnic composition

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...

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.
