Problems solved by technology

The raw materials for the preparation of the former firecrackers contain potassium perchlorate, an explosive substance that is strictly controlled by the state, so the safety of this kind of firecrackers is poor; the raw materials for the firecrackers applied for by the latter use flour as the binder of the grains, and the firecrackers made have a low sound when set off. , weak festive effect, and the firecrackers made by mixing the two kinds of medicines have poor continuity of discharge, insufficient combustion of the medicines and low discharge rate, and it is difficult to meet environmental protection requirements.

Abstract

The environment protecting color-liquid firecrackers consists of adhesive casing, internal safe lead and chemical grains and features that the chemical grain consists of inner kernal comprising red lead powder, copper oxide powder, Al-Mg alloy and PVA adhesive; and outer coating comprising potassium nitrate, Al-Mg alloy, charcoal. sulfur, aluminium dregs and phenolic resin. The firecrackers and produced through pelletizing in steel sieve, rolling to form inner kernel, rolling to adhere outer coating to inner kernel and other steps. It is safe in production, storage, transportation and firing and has large sound produced.

Description

technical field [0001] The invention relates to a firecracker and a production method thereof, in particular to an environment-friendly and safe colored light firecracker and a production method thereof. Background technique [0002] my country is an ancient civilization with a long history and splendid culture in the world. For thousands of years, firecrackers have become a unique way for people to express joy and mourn. However, traditional firecrackers use explosive substances as raw materials, and the production process is complicated, most of which are manually operated, with many unsafe factors. The production, storage, transportation, and discharge of firecrackers are dangerous and costly, which seriously restricts the development of the market. In recent years, some new types of firecrackers have appeared on the market, such as the application number 89100283 named colored beads safety electro-optic firecrackers, and the application number 95110824.7 named special t...
