Embodiment 1

[0044] Assuming that 100 parts by weight of plant fibers are prepared, the following components are preferably in the ratio of parts by weight: 100 parts by weight of corncobs, 80 parts by weight of nitric acid, 50 parts by weight of sulfuric acid, 5 parts by weight of diphenylamine, 5 parts by weight of camphor, and 3 parts by weight of soda ash. parts by weight, 90 parts by weight of alcohol.

[0045] Smokeless cellulose preparation method of the present invention comprises the following steps:

[0046] ① Raw material screening and grading, screening and grading the crushed various plant fiber powders into 120 mesh for the first grade and 60-100 mesh for the second grade;

[0047] ② Soak with soda ash respectively, add 600 parts by weight of water and soda ash in the above-mentioned preferred components according to 100 parts by weight of plant fiber, stir evenly and soak at room temperature for 72 hours. The main purpose of soaking is to remove impurities, fat and starch ; ...

Embodiment 2

[0054] Assuming that 100 parts by weight of plant fibers are prepared, the following components are preferably in the ratio of parts by weight: 50 parts by weight of corn stalks, 50 parts by weight of bamboo, 40 parts by weight of nitric acid, 10 parts by weight of sulfuric acid, 1 part by weight of diphenylamine, camphor 1 part by weight, 9 parts by weight of soda ash, and 55 parts by weight of banana water, the same preparation method as in Example 1 was used to prepare the smokeless cellulose firework whipping agent of the present invention.

Abstract

The invention discloses a smokeless cellulose which is used for preparing fireworks. The smokeless cellulose is a solid-state micropowder or particle agent. The invention is characterized in that the smokeless cellulose is prepared by nitrating plant fiber and comprises the following components in parts by weight: 100 parts of plant fiber, 40-80 parts of 60-98% nitric acid, 10-50 parts of 60-98% sulfuric acid, 0.5-5 parts of diphenylamine, 0.5-5 parts of camphor, 1-10 parts of sodium carbonate and 50-100 parts of solvent, wherein the plant fiber is one or mixture of pulverized corn cob, corn stalk, bamboo, boon, peanut shell, reed and sugar cane waste residue in any weight ratio; the mixture of nitric acid and sulfuric acid is used as a nitrating agent; the mixture of diphenylamine and camphor is used as a stabilizer; and the solvent is alcohol, banana oil, aether or acetone. The invention has the advantages of high safety, high stability, no smoke, no smell, no toxicity, no dust, environmental protection and the like.

Description

technical field [0001] The invention relates to a medicament for preparing fireworks whipping, in particular to a kind of smokeless cellulose. Background technique [0002] Fireworks whipping has a production history of thousands of years in our country. The discharge of its products has brought great joy and auspiciousness to people, and also brought considerable social and economic benefits. However, the production enterprises have also paid a huge amount of life for this. Property losses are mainly manifested in the frequent casualties caused by explosions during the production, storage and transportation of fireworks products. One of the important reasons is the high friction and impact sensitivity of the pharmaceutical materials used in the production of fireworks. Due to friction or impact when preparing medicines and mixing, it is very easy to cause explosion and injury accidents, which is very unsafe in production, use and transportation. Although the main raw mater...
