Problems solved by technology

However, since the price of fireworks that can form pictures and texts in the sky is much higher than that of ordinary fireworks on the market, there were very few batches of pictures and texts for sale before this, and they were usually ordered by the government or enterprises
[0004] Nowadays, with the improvement of living standards, people's entertainment requirements and consumption vision are also constantly improving. Fireworks are an old-fashioned product that has lasted for thousands of years. There are many types of fireworks, and many classic products have been derived. However, with the development of science and technology, the original model has basically developed to the top. It is a new type of firework product that can be popularized and everyone can consume. In large-scale events, such as the Olympic Games, people use countless pictures of fireworks, and use a large number of people and many computers to control them simultaneously to generate footprints in the sky. However, this method It requires a lot of manpower and material resources, is expensive, and requires multiple coordination and training, so it is difficult for people to copy and bear this kind of consumption. At present, some companies and individuals have made some attempts and research on graphic fireworks. These individuals and companies have : Z

preparation example Construction

[0075] refer to figure 1 As shown in FIG. 9 , a special propellant block for graphic fireworks lattice projectile and its preparation method, including a propellant block 1 and a preparation method of the propellant block 1, the propellant block 1 is set as a columnar propellant block 1, the The columnar gunpowder block 1 is made by bonding the firework launch block 2 and the firework display block 3 through the combustion-supporting paste sheet 4; the combustion-supporting paste sheet 4 includes the paste sheet 4 and the adhesive arranged on the paste sheet 4; The fireworks launching block 2 is a fireworks launching block 2 made by mixing the pyrotechnic propellant that is launched into the air by conventional fireworks and firecrackers in the industry, and the ignition performance enhancer and an organic binder; The pyrotechnic display block 3 made by mixing the pyrotechnic display medicine with organic binder and passivating agent; the shape, size and quality of the columna...

specific Embodiment

[0115] In actual production, such as figure 1 As shown, firstly, use a conventional gunpowder granulator to manufacture the powdered propellant propellant into granular propellant propellant with consistent shape, size and quality, and carry out 99% organic binder and 1% ignition performance enhancer. Mix and stir evenly to obtain the first binder used in the granular pyrotechnic propellant, and then add 85% of the granular pyrotechnic propellant and 15% of the first binder to a conventional gunpowder mixer in turn for mixing and stirring, After stirring, the pyrotechnic propellant particles with a binder on the surface are obtained; the pyrotechnic propellant particles with a binder on the surface are filled into the molding cavity of the first molding fixture according to 85% of the mass ratio of the powder block specification, and the first molding tool is used. A forming pressure rod on a forming fixture presses the fireworks propellant in the forming cavity, so that the p...

Abstract

The invention discloses a special gunpowder block for a graphic fireworks dot matrix emitter and a preparation method thereof. The special gunpowder block for the graphic fireworks dot matrix emittercomprises a gunpowder block, wherein the gunpowder block is arranged as a columnar gunpowder block, which is prepared by bonding a fireworks emitting block and a fireworks display block through a combustion-supporting paste sheet; the combustion-supporting paste sheet comprises a paste sheet and an adhesive arranged on the paste sheet; the fireworks emitting block is a fireworks emitting block prepared by mixing fireworks propellants launched from conventional fireworks in the industry, an ignition performance enhancer and an organic adhesive. The gunpowder block provided by the invention is integrally formed by the fireworks emitting block and the fireworks display block through the combustion-supporting paste sheet, so that the fireworks emitting block and the fireworks display block arenot only clear, but also firmly connected and not easy to separate; the added paste sheet is helpful to slow down the ignition of the fireworks display block during emission; and the ignition performance enhancer and a passivating agent added in the gunpowder block can help the ignition of the fireworks emitting block and slow down the combustion speed of the fireworks display block.

Description

technical field [0001] The invention relates to the field of fireworks with pictures and texts, in particular to a powder block dedicated to a lattice emitter of fireworks with pictures and texts and a preparation method thereof. Background technique [0002] Fireworks are products that can form colors, patterns, and produce sound effects when they are set off, and are mainly visual effects. At first, fireworks were a pastime exclusively for the rich and the rich. In the Ming and Qing Dynasties, the technology of fireworks production had new developments, and gradually became festival gifts. Every Spring Festival, Lantern Festival and other major events, fireworks are set off to add to the fun. [0003] There are many types of fireworks in our country, and the designs and colors are quite mixed. Among them, the chrysanthemum type is the most popular flower type. After the fireworks are shot into the sky, first the colorful light agents burn, and then the parachutes that o...
