Description

Background Art

[0001] In the prior art, the technical solution to produce the light and color floating effect is to wrap the pyrotechnic powder with a fast burning speed in the effect fuse, and a large number of effect fuses are placed in the inner tube to be launched into the air and exploded. By utilizing the characteristics of the end of the effect fuse being ignited by fire, a large number of effect fuses are driven by the working energy of the combustion ejected at their end to swim in the air, forming the corresponding light and color floating effect. For example, the Chinese patent document No. CN202938722U discloses "An effect fuse for fireworks".

[0002] The disadvantages of the prior art are: the ignition rate of the effect fuse that can only be ignited at the end is low, the cost of achieving a predetermined density of floating light color effect within a set airspace is increased, and the effect fuse that fails to ignite leads to waste and safety hazards; the effect fuse that can only burn at the end has a small luminous surface, the light color of the floating effect is dim, and its firing effect defects are more obvious.

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 This is a schematic diagram of the principle structure of the fireworks bright beads (the outer layer and the middle layer are partially broken). DETAILED DESCRIPTION

[0022] Referring to the attached drawings, a specific structure of the present invention is shown. The fireworks beads that produce the light and color floating effect are a three-layer structure consisting of a core 1, an intermediate layer 2 and an outer layer 3;

[0023] The core powder constituting the core 1 can be selected from red, green or yellow core powder according to the needs of the fireworks design; in the example, the components and weight ratio of the red core powder are: 5 potassium perchlorate, 2 aluminum-magnesium alloy, 2.2 strontium carbonate, 0.3 paint flakes, 0.5 phenolic resin, 0.7 polyvinyl chloride, and 0.4 strong glue powder; the components and weight ratio of the green core powder are: 2 potassium perchlorate, 2.5 aluminum-magnesium alloy, 3.5 barium carbonate, 1 chlorinated paraffin, 0.7 phenolic resin, and 0.3 strong glue powder; the components and weight ratio of the yellow core powder are: 4.5 potassium perchlorate, 1.5 cryolite, 2 aluminum-magnesium alloy, 0.2 paint flakes, 0.5 phenolic resin, 0.5 polyvinyl chloride, 0.8 strontium carbonate, and 0.3 strong glue powder.

[0024] The components and weight ratio of the drug contained in the intermediate layer 2 are: 90% methyl silicone rubber and 10% paint flakes.

[0025] The components and weight ratio of the outer coating drug constituting the outer coating 3 are: 85 active copper sulfide and 15 potassium perchlorate.

[0026] The weight ratio of the core medicine to the middle medicine is 10:2, and the weight ratio of the core medicine to the outer medicine is 10:1.

[0027] The preparation method of the fireworks bright beads is:

[0028] The S1 core drug is mixed uniformly, granulated, and dried according to a general method to obtain a core, wherein the particle size of the core is 14 to 16 meshes;

[0029] S2 The middle package medicine is mixed evenly according to the general method, a moistening amount of solvent (such as alcohol) is added, and the core is put into a drum and rotated together so that the middle package medicine is evenly wrapped on the core, and dried to obtain a semi-finished product;

[0030] S3 outer coating medicine is mixed evenly according to the general method, a moistening amount of solvent is added, and it is put into a drum together with the semi-finished product and rotated so that the outer coating medicine is evenly wrapped on the semi-finished product, dried, polished, and the bright bead finished product is obtained.

[0031] The finished bright bead is loaded into the inner tube according to the general method, and the ignition fuse is installed, and then placed in the outer tube for launching. When the inner tube explodes, the outer package charge on the outer surface of the bright bead is ignited. Since the bright bead is a spherical structure, the entire spherical surface is ignited, which greatly improves the ignition rate compared with the existing effect fuse that can only ignite at the end.

[0032] The earliest ignition point of the outer charge ignites the local middle charge of the middle layer, and penetrates the middle layer to ignite the core charge. Since the burning rate of the core charge is much higher than that of the middle charge, the core charge explosion gas is ejected from the local area and its inertia drives the bright bead to swim in the air, forming a corresponding light color floating effect until the entire bright bead is burned out. Compared with the luminous surface of the fuse ignited at the end, its luminous surface is larger and brighter.

[0033] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and describes these embodiments in detail in conjunction with the accompanying drawings in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is only limited by the claims and their full scope and equivalents, and is not limited by the specific embodiments disclosed.
