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 firework setting off base is to add 0.6-3.5 times the water of the total amount of starch after disintegrating the pulp, then add 5%-60% of the starch and stearic acid in the release agent, stir evenly and then stir Heat until the starch is completely gelatinized, cool slightly, add the remaining ingredients, mix thoroughly to form a mud, take the 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 Dry and release the mold to get the product.

[0029] If inorganic fillers are used, after the starch is completely gelatinized, cool slightly, and then add 0.01-0.2 times the amount of starch release agent, 0.5-4 times the amount of starch inorganic fillers and the rest of the starch.

example 1

[0031] Example 1. Take 100g of coniferous wood pulp, filter it with hydraulic disintegration, squeeze it dry, add water to adjust the total weight to 700g, add 50g starch and 10g stearic acid, stir well, and heat until the starch is completely gelatinized while stirring. Cool slightly, then add 950g of starch and 500g of talcum powder, 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 it warm until no steam is released, and then take it out of the mold.

example 2

[0032] Example 2. Take 1 kg of waste paper, disintegrate it with water, filter it, squeeze it dry, add water to adjust the total weight to 4.5 kg, add 0.6 kg of starch and 100 g of stearic acid, stir well, and heat until the starch is completely gelatinized while stirring. Cool slightly, then add 0.4kg of starch, 100g of zinc stearate, 2.5kg of talcum 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 fireworks launcher with a mold temperature of 280°C, keep it warm until no steam is discharged, and then take it out of 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 base material for setting off fireworks and a preparation method for the base. Background technique [0002] Currently popular bases on the market, such as fireworks combinations, the launch tube is to seal the lower ends of several paper tubes of equal length with mud, poke holes on the tube wall close to the mud seal above the mud seal to penetrate the fuse, and then put After they are put together in a row, they are pasted with paper and fixed. Several such "tube arrays" with the same number of tubes or different ones are stacked one by one and fixed with paper to form a rectangular arrangement or other polygonal arrangement of "tube arrays" to form a combined firework launch tube. Its production method is to go through the steps of coiling tube, beating mud (back cover), piercing eyes, piercing fuze, spelling, bonding, stacking, and applying paper hoops. Not only is the process complicated and the production cost is hig...
