Problems solved by technology

The discharge effect of the existing colored bright beads is only a kind of colored light group acting in an instant, including the existing fireworks bright beads that produce the effect of "comet tail". The burning duration is very short, and the visual effect time for the audience is short. , and the effect screen is small, resulting in a poor overall visual effect for the audience

Embodiment 1

[0016] Embodiment 1: the making process of the coma red bright pearl that fireworks are used is as follows:

[0017] 1. After the flake aluminum powder is passed through an 80-mesh sieve, it is coated with tung oil. The process includes the following steps:

[0018] Step 1: Put tung oil in a container and heat it to 60-80°C; Step 2: Add flake aluminum powder into the container and stir evenly, take out flake aluminum powder after 3-5 minutes, spread it out and cool it, and you get it.

[0019] 2. Production of effect drug core: Weigh the following components according to the ratio of parts by weight: 50 parts of potassium perchlorate, 15 parts of magnesium aluminum alloy powder, 10 parts of strontium carbonate, 15 parts of coated flake aluminum powder, 5 parts of starch 5 parts of polyvinyl chloride, each component is sieved and mixed uniformly according to the general method, then add an appropriate amount of ethanol to granulate, and dry to obtain the formed red effect drug ...

Embodiment 2

[0022] Embodiment 2: The difference between the manufacture process of the comet wave green bright pearls that fireworks are used and embodiment 1 is: the prescription that effect drug core is made is: by weight ratio, 20 parts of potassium perchlorate, 15 parts of magnesium-aluminum alloy powders , 40 parts of barium nitrate, 15 parts of coated flake aluminum powder, 5 parts of starch, and 5 parts of polyvinyl chloride. All the other are identical with embodiment 1.

Embodiment 3

[0023] Embodiment 3: The difference between the manufacture process of the comet wave yellow bright pearls used by fireworks and embodiment 1 is: the formula that the effect drug core is made is: by weight, 45 parts of potassium perchlorate, 20 parts of magnesium-aluminum alloy powder , 10 parts of sodium fluorosilicate, 15 parts of coated flake aluminum powder, 5 parts of dextrin, and 5 parts of polyvinyl chloride. All the other are identical with embodiment 1.

Abstract

The invention discloses a comet-wave colored bright bead for firework. The comet-wave colored bright bead is composed of an internal effect powder core and an external ignition powder layer. The effect powder core is selected from one of four powder cores, namely a red effect powder core, a green effect powder core, a yellow effect powder core and a blue effect powder core. The effect powder and the ignition powder are prepared according to a formula, and the effect powder undergoes uniform mixing, granulation and drying to obtain molded effect powder cores in various colors. An organic solvent is sprayed on the molded effect powder core, and then the molded effect powder core is put into the ignition powder to be stirred and wrapped to obtain the bright bead. The bright bead has good bright bead general performance and long duration of combustion, and has long duration of visual effect, grand scene, stable property at normal temperature, long shelf life, pure flame color and excellent color saturation. And burn cut-off height accords with fire danger prevention standard.

Description

technical field [0001] The invention relates to a firework pyrotechnic agent mixture, in particular to a kind of colorful bright beads for fireworks. Background technique [0002] In the prior art, the colorful bright beads used in fireworks all use combustibles and oxidants to undergo oxidation-reduction reactions at high temperatures, and a large amount of light and heat are generated in the reaction process. Flames of different colors are produced. The discharge effect of the existing colored bright beads is just a kind of colored light group that acts instantaneously, including the existing fireworks bright beads that produce the effect of "comet tail". The burning duration is very short, and the visual effect time for the audience is short. , and the effect screen is small, resulting in a poor overall visual effect for the audience. Contents of the invention [0003] In order to overcome the above-mentioned defects, the technical problem to be solved by the present ...
