Abstract

The invention discloses a set-off shell material for fireworks and crackers, which is prepared from the following raw materials in portion by weight: 1 to 2.5 portions of starch, 1.5 to 3 portions of vegetable fiber, 4.5 to 8 portions of clay, 0.09 to 1.0 portion of activating agent, and 0.1 to 0.9 portion of stabilizing agent. The shell material takes the clay as a base material and the starch and the vegetable fiber as auxiliary materials and can be biodegraded in the natural environment, which is advantageous for environmental protection, and the prepared shells of the fireworks and the crackers have high strength, are high-temperature resistant, reduce the possibility of undershooting during the of setting off, and reach the standard of 'method for compression and stacking tests by a compression testing machine' of GB/T4857.4-2008. The fireworks and the crackers made from the set-off shell material prepared by the method have high strength, strong set-off performance and high safety performance, and reach the standards of GB10631-2004, GB19593-2004 and GB19594-2004.

Description

technical field [0001] The invention relates to a blasting device and a preparation method thereof, in particular to a device for fireworks and firecrackers and a preparation method thereof. Background technique [0002] Fireworks and firecrackers have a long history in our country, and are deeply loved by people for their brilliance. With the improvement of people's material living standards and the change of viewing interest, the requirements for fireworks and firecrackers are getting higher and higher. It is hoped that there will be rich and colorful fireworks and firecrackers, which will produce various colorful fireworks and firecracker effects, which are pleasing to the eye. pleasure. [0003] In addition to the increasing requirements for the quality of fireworks and firecrackers, the packaging materials of fireworks and firecrackers have also attracted much attention. The traditional packaging materials for fireworks and firecrackers are mainly formed paper, which i...
