Embodiment 1

[0023] Embodiment 1, take making 19 rounds / height 17.5cm / inner diameter 0.3cm combination potted flower outer cylinder as example.

[0024] 1. According to the ratio of parts by weight, 12 parts of tapioca starch, 8 parts of wood chips, 10 parts of paper pulp, 55 parts of Shuangfei powder, 1.5 parts of stearic acid, 5 parts of gypsum, and 8.5 parts of light calcium carbonate were weighed for each raw material component, The components are mixed in a general way; boiled water is added according to the weight ratio of 100 parts of the above mixture plus 30 parts of boiled water and stirred evenly.

[0025] 2. Take 2.4kg of the product obtained in the previous step, put it into the mold frame of the potted flower outer cylinder with 19 rounds / height 17.5cm / inner diameter 0.3cm, set the working pressure of the hydraulic press to 10 kgf / cm2, press and shape, and at the same time through electric heating The mold is heated to 200°C to dry and set, and after 5 minutes, the mold is de...

Embodiment 2

[0027] Embodiment 2, taking the thick spherical shell of making R45 millimeter * 4 millimeters as example:

[0028] 1. By weight: 6.5 parts of cornstarch, 6.5 parts of glutinous rice flour, 7.5 parts of rice husk, 6.5 parts of paper pulp, 57.5 parts of Shuangfei powder, 4.5 parts of silicate, 11 parts of light calcium carbonate, and weigh each raw material component , mix each component by general method; add boiled water according to the weight ratio of 100 parts of the above mixture plus 25 parts of water and stir evenly.

[0029] 2. Take 65 grams of the product obtained in the previous step, put it into a 4-inch spherical shell mold frame, use a pressurized cylinder device to set the working pressure at 5 kgf / cm2, and press it into shape, and at the same time heat the mold to 200°C for drying through oil temperature Dry setting, demoulding after 1 minute and 20 seconds to obtain the finished product.

[0030] Compared with the existing paper spherical shell of the same spe...

Embodiment 3

[0032] Embodiment 3, take making special-shaped product " grenade " (grenade profile) and " frog prince " (frog profile) as example:

[0033] 1. parts by weight: 15 parts of flour, 5 parts of straw, 10 parts of paper pulp, 10 parts of sawdust, 48.5 parts of talcum powder, 1.5 parts of stearic acid, 10 parts of light calcium carbonate, each raw material component is weighed, each The components are mixed in a general way; boiled water is added according to the weight ratio of 100 parts of the above mixture plus 45 parts of water and stirred evenly.

[0034] 2. Take the product obtained in the previous step as needed and put it into the mold frame, use the pressurized cylinder equipment to set the working pressure to 20 kgf / cm2 for pressing and molding, and at the same time, heat the mold to 200 °C for 2 minutes. After 20 seconds, the mold is demoulded to obtain the finished product.

[0035] The difficulty in the development of special-shaped products in the fireworks industry...

Abstract

The invention discloses a compression molding fireworks outer cylinder, a marble shell and a preparation method thereof, comprising the components of plant fiber, binder, filler, excipient and dryer. The fireworks outer cylinder and marble shell is made after the components are prepared and processed compression molding. The lead-through is just needed to be installed by the fireworks manufacturers, and the fireworks cylinder can be made by using the technical proposal. The process is simple, the procedures are few and the production efficiency is high. The utilization rate of the raw materials can be reached to 100 percent. The plastics can be totally banished and the effect of environmental protection is good. The products have standard specification and good pressure resistance. The distortion and bending phenomena can not be generated, and the display quality of the fireworks is greatly improved which ensures the safety. The shape, size and intensity of the fireworks cylinder and marble shell can be flexibly and conveniently changed as required. The preparation method also can be used for the production and development of the special shaped shell or package in the fireworks industry.

Description

technical field [0001] The invention relates to a fireworks part and a manufacturing method thereof, in particular to a molded fireworks outer cylinder, a fireworks shell and a manufacturing method thereof. Background technique [0002] At present, the production method of the fireworks outer cylinder is to use paper as a raw material. The production process includes: paper cutting, gluing, rollers, edge trimming, drying the cylinder, bundling the cylinder, beating the bottom of the yellow mud, dismantling, arranging into strips, drilling, Drainage, group pots, etc. Also need to consume a lot of glue and paper in the above process. [0003] The current production process of fireworks marble shells is to first cut a large sheet of yellow cardboard into corresponding small pieces of paper patterns according to the different sizes and shapes of the ball shells, then paste the multi-layer paper patterns layer by layer to a certain thickness, and then heat-press after drying. F...
