Nitro smokeless lignocellulose and its preparation method

Abstract

The invention discloses a nitro smokeless lignocellulose and a preparation method thereof. It is mainly used for the preparation of fireworks and firecrackers. It is characterized in that it includes wood fiber powder, acid mixed solution, dilute nitric acid solution, nitrification mixed solution, neutralization solution, stabilizer, and is prepared by secondary acid solution soaking and nitrification reaction after neutralization. The proportioning of the above-mentioned components and parts by weight is: 100 parts by weight of wood fiber powder, 50-90 parts by weight of acidic mixed solution, 50-70 parts by weight of dilute nitric acid solution, 100 parts by weight of nitrated mixed solution, and 30 parts by weight of neutralizing solution. -50 parts by weight, 1-4 parts by weight of stabilizer. The invention has the advantages of high safety, good stability, no smoke, no taste, no poison, no dust, environmental protection and the like.

Description

technical field [0001] The invention belongs to the technical field of fireworks medicaments, and in particular relates to nitro anthracite lignocellulose for preparing fireworks whipping medicaments and a preparation method thereof. Background technique [0002] Fireworks and whips have been the mascots of people's celebrations for thousands of years, and they bring people great joy. However, because fireworks whipping is a special product that is flammable and explosive, it is very prone to explosion and combustion due to its high friction sensitivity and impact sensitivity during production, storage, transportation and discharge, causing casualties and property losses. Bring serious pollution to the environment. [0003] In recent years, domestic and international requirements for environmental protection have become higher and higher, and people's awareness of environmental protection has become stronger and stronger. Therefore, fireworks and firecrackers must also deve...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems existing in the above-mentioned prior art, and overcoming the disadvantages of poor safety performance, non-environmental protection and the limitations of smokeless medicaments in the existing fireworks medicaments, the purpose of the present invention is to provide a nitro-free medicament for preparing fireworks whipping. Tobacco lignocellulose and its preparation method, the product uses waste wood, waste board, waste wood residue and other waste materials as raw materials, has the characteristics of no smoke, no peculiar smell, no radioactivity, no harmful gas, etc., and can effectively solve the problem of disposing of waste wood materials and environmental pollution issues
