Low performance compound potassium powder additive

Abstract

Disclosed is a low performance composite potassium powder additive for fireworks and firecrackers which is prepared from charging 30-50 wt% potassium chloride and -50-70 wt% sodium chlorate through mixing homogeneously, reacting 3-5 hours at the condition of 100 deg. C steam, cooling down the product, separating sodium chloride to obtain half-finished potassium chlorate product, immersing the potassium chlorate for second dissolution, charging potassium nitrate and barium nitrate 10-40% of weight of potassium chlorate, reacting 2-4 hours at the condition of 100 deg. C steam, natural cooling for crystallization, scouring, centrifugally separating, drying and chalking to 200-250 mesh, charging light calcium carbonate 5-10% of weight of disintegrated article, and mixing homogeneously.

Description

technical field [0001] The invention relates to a gunpowder for fireworks. Background technique [0002] In the prior art, chlorate gunpowder (such as potassium chlorate) is the main raw material for producing matches, fireworks and firecrackers. Mixed pyrotechnic agents as oxidants have good flammability, explosiveness and color-helping properties, so they are widely used in the civil pyrotechnic industry. However, due to the high mechanical sensitivity of chlorate gunpowder, potassium chlorate cannot be co-ground with organic matter. When it is mixed with sulfur, phosphorus, organic matter or combustible matter and rubbed or collided, it is very easy to explode, and it is prone to safety accidents during use. This not only brings huge losses to the national economy and people's lives and property, but also brings heavy psychological pressure to producers. Contents of the invention [0003] The technical problem to be solved in the present invention is to propose a low-...
