Problems solved by technology

Not only is the process complicated and the production cost is high, but the paper tube is easily deformed, which affects the emission effect, and more importantly, it consumes a lot of paper, which is not conducive to environmental protection.

preparation example Construction

[0028] The preparation method of the fireworks display base is to disintegrate the pulp and add 0.6-3.5 times of water to the total amount of starch, then add 5%-60% of starch and stearic acid in the release agent, stir evenly, and then stir while stirring. Heat until the starch is completely gelatinized, cool down a little, add the remaining components, mix thoroughly into a mud, take a mud suitable for the mold cavity, fill it into a mold with a mold temperature of 150-280 ° C, close the mold and keep it warm until After drying, the product is obtained from the mold.

[0029] If inorganic fillers are used, after the starch is completely gelatinized, cool it down a little, add 0.01-0.2 times the amount of starch as a mold release agent, 0.5-4 times the amount of starch and inorganic fillers and the rest of the starch.

example 1

[0031] Example 1. Take 100g of softwood pulp, disintegrate with water, filter, squeeze dry, add water to adjust to a total weight of 700g, add 50g of starch and 10g of stearic acid, stir well, and heat while stirring until the starch is completely gelatinized. Cool slightly, then add 950g of starch and 500g of talc, and mix well. Take an appropriate amount of the mixture and fill it into a firework discharge tube mold with a mold temperature of 150°C, keep the temperature until no steam is discharged, and then eject the mold.

example 2

[0032] Example 2. Take 1Kg of waste paper, disintegrate with water, filter, squeeze dry, add water to adjust to a total weight of 4.5kg, add 0.6kg of starch, 100g of stearic acid, stir well, and heat while stirring until the starch is completely gelatinized. Cool slightly, then add 0.4kg of starch, 100g of zinc stearate, 2.5kg of talc powder, and 1.5kg of clay powder, and mix well. Take an appropriate amount of the mixture and fill it into the mold of the combined firework launch base with a mold temperature of 280°C, keep the temperature until no steam is discharged, and then eject the mold.

Abstract

The invention provides a firework display base materials based on starch and the preparation method and relates to a preparation method of firework display base material and the base. The preparation method is that proper amount of water is poured after starch, grain powder or pulp are fragmented, part or all of release agent is added, then after being agitated uniformly, agitating while heating until the starch is totally gelatinized, slightly cooler, residual materials are poured in and mixed thoroughly into gray gunk. The gray gunk is filled into a die with a temperature of 150-280 DEG C, the die is closed to keep the heat until being dried, then a product is get after unloading from the die. The pulp is waste or new pulp or a market pulp board and the release agent is stearic acid, silicone oil or stearate. Based on the starch as the base material and supplemented by paper fiber, the invention has high strength and reduces possibilities of impacting the bottom when transmitting; a contour forging once-through shape craft is adopted which is very simple, the quality of the product is stable, and the individual difference is little without any deforming, moreover manpower is saved. By replacing the die, the invention can produce display shells, firework display tubes and various firework bases.

Description

technical field [0001] The invention relates to a fireworks display base material and a preparation method of the base. Background technique [0002] At present, the popular bases on the market, such as fireworks combination, the launch tube is to seal the lower ends of several equal-length paper tubes with mud, and poke holes in the tube wall close to the mud seal above the mud seal to pass through the fuze, and then put the fuse. Put them together in a row and glue them together. A number of such tubes of the same number or different "tube arrays" are stacked and fixed with paper to form a rectangular arrangement or other polygonal arrangement of "tube arrays" to form a firework combination launch tube. The production method is to go through the steps of rolling the tube, playing mud (back cover), dazzling, threading the fuze, arranging, gluing, stacking, applying paper hoop and the like. Not only the process is complicated and the production cost...
