Non-sulphur firecracker components and preparation thereof

Abstract

The invention discloses a sulfur-free firecracker medicament and a method for the production thereof, and the medicament constituents are 50 to 70 parts of potassium perchlorate, 20 to 45 parts of aluminum powder, 5 to 20 parts of pearl powder, 10 to 30 parts of modified wood flour, and 0 to 5 parts of a mixture of ferroferric oxide and manganese dioxide or one material thereof. The preparation of the sulfur-free firecracker medicament is mainly characterized in that the wood flour undergoes the imbibitions treatment and the surface treatment by adopting a potassium nitrate and a micro-crystalline wax respectively. The sulfur-free environment-friendly firecracker produced by the sulfur-free firecracker medicament system of the invention has advantages of sonorous sound when setting off the firecracker, high rate of sonority, non discharge of noxious gas of sulfur dioxide, easy obtaining of constituents and materials, rather low cost, not containing prohibited articles such as potassium chlorate and being fully fit to replace the current sulfur-bearing firecracker.

Description

technical field [0001] The invention relates to a firecracker product, in particular to a sulfur-free firecracker medicinal formula and a preparation method thereof. Background technique [0002] Firecrackers are the crystallization of our people's hard work and wisdom, and they have brought endless joy to people all over the world. As early as more than one thousand years ago, the ancient people of our country had mastered the production technology of firecracker products. Ancient firecracker gunpowder is made by mixing potassium nitrate, sulfur, and charcoal. The general formula is 75 parts of potassium nitrate, 10 parts of sulfur, and 15 parts of charcoal. Now the performance of firecracker products has been greatly improved. It is made of potassium chlorate, potassium perchlorate, sulfur, and aluminum silver powder. The general formula is: 50 parts of potassium chlorate or potassium perchlorate, 25 parts of sulfur, and 25 parts of aluminum silver powder. . [0003] Fr...

Problems solved by technology

Also have on the basis of traditional firecrackers, do not change structure, technology, and the principle of sounding, only improve the invention of medicine formula, for example CN85101596 discloses " the manufacture of sulfur-free aromatic firecrackers " exactly adopts sulfur-free formula, but its shortcoming is that can no longer To meet the needs of the development of the times, the formula applied in it uses potassium chlorate as the oxidant, and now for safety reasons, relevant laws and regulations in our country have banned the use of potassium chlorate to produce firecracker products
