Abstract

The invention discloses a firework cylinder material which is prepared from the following components in percentage by mass: 20-55% of plant fiber, 0-15% of reinforcing fiber, 1-5% of fiber finishing agent, 25-39% of air hardening material, 0.1-2% of catalyst, 5-25% of filler, 0-2% of lubricant, 0-2% of water-condensing agent, 5-15% of toughener and 0-5% of foaming agent, wherein stabilizer accounts for 2-15% of the total mass of the formula. The invention also discloses a preparation method of the firework cylinder material. The technical scheme can completely replace the traditional firework cylinder production mode, and is high in processing operability, high in molding speed and easy to realize large-scale stable production; and meanwhile, the raw materials are abundant, easy to acquire and low in cost. Besides, the produced firework cylinder can achieve qualified mechanical strength and favorable physical / chemical stability, causes no environmental pollution and can be degraded naturally.

Description

technical field [0001] The invention relates to a fireworks barrel material and a preparation method thereof. Background technique [0002] Traditional fireworks outer cylinders are mainly made by hand, and the main raw material is paper. Its production method is: paper cutting, gluing, roller, trimming, drying, bundling, sealing, drilling, inserting lead wires, etc. At present, this traditional production method is still the most important production method of the outer tube of fireworks. The disadvantages of the above methods are that there are many processes, low processing efficiency, long production time, and a large amount of paper and glue are consumed. [0003] In order to overcome the inefficiency of traditional fireworks outer cylinders, people in the industry have developed many new manufacturing methods, but in the end, due to problems such as production efficiency, strength, environmental protection, and energy consumption, it is impossible to mass-produce and...
