Abstract

The present invention discloses explosive black powder that is used for fireworks. The black powder contains the following components with the following weight portions: 40 to 75 portions of potassium perchlorate, 0 to 35 portions of potassium nitrate, 1 to 5 portions of potassium dichromate, 5 to 15 portions of sulfur, 5 to 25 portions of charcoal, 0.5 to 2 portions of carbon black, and 5 to 20 portions of potassium terephthalic acid or potassium acid phthalate. The explosive black powder is made of the components according to the ratio. No metal material or toxic substances are used. The explosive black powder has the advantages of low mechanical sensitivity, excellent stability, large explosive scale, excellent explosive sound, black medicine, easily prepared raw materials and relatively low cost. Thus the explosive black powder is the ideal explosive black powder.

Description

technical field [0001] The invention relates to a cracking powder for fireworks products, in particular to a black powder for cracking firework or potted flower products. Background technique [0002] At present, the air-exploding effect of fireworks products, that is, the air-expanding effect of fireworks or potted flowers, is generally achieved through the combustion and explosion of explosives. The performance of explosives directly affects and determines the effect and quality of fireworks or potted flowers. Therefore, many Firework technicians have all carried out a large amount of tests and researches on breaking explosives, making every effort to produce good stability, low cost, and good breaking explosives. According to the laws and regulations of various countries, explosives can be roughly divided into white explosives and black explosives. [0003] The so-called Baiyao explosive is a pyrotechnic powder formulated with active metal powder such as aluminum, magnes...
