Embodiment 1

[0011] Example 1, the following raw materials are mixed (unit: kilogram)

[0012] Potato starch 6; straw fiber 4; calcite 20; fat oil mixture 1; montmorillonite 4.

[0013] The above mixed raw materials are processed by the following steps to obtain the outer cylinder of fireworks formed by mechanized hydraulic mold at high temperature:

[0014] The first step: mixing ingredients: use a mixing machine to mix the raw materials, and then use a mixer to add an appropriate amount of normal temperature boiling water to stir;

[0015] The second step: high-temperature hydraulic mold forming: according to the first step and the prepared raw materials, pour the material into the hydraulic mold cavity of the hydraulic press with the material distribution plate, and the hydraulic press is closed. At the same time, the heat-conducting oil furnace sends the heat-conducting oil into the hydraulic press mold. Circulating heating, so that the temperature inside the mold is 120-320 degrees, ...

Abstract

The invention provides an application of straw fiber in the production process of high-temperature molded fireworks outer cylinder, the material composition of which includes the following raw materials in proportion by weight: plant starch 6-30; straw fiber 4-60; filling mixture 20-60 ; Catalyst 1‑12; Stabilizer 4‑25. The raw materials are processed by mixing materials and high-temperature hydraulic molds. The production process of the present invention has high production efficiency and can be produced in an assembly line. Compared with the traditional paper outer cylinder, the drying time is reduced, and the effect is more obvious in seasons with excessive rainy weather; the materials of the present invention are easy to degrade material, the outer cylinder after discharge can be used as fertilizer after degradation, and discharge is safe.

Description

technical field [0001] The invention relates to a manufacturing process of an outer cylinder of fireworks and firecrackers. Background technique [0002] The traditional outer cylinder of fireworks and firecrackers is mainly made of molded paper, which is rolled into a paper cylinder by a reel machine or bonded with multiple pieces of molded paper into a cardboard with a certain thickness, and then pressed by a molding machine to form an outer cylinder. Or manually rolled. This kind of traditional technology and material process is complicated, the production efficiency is low, the environment is polluted, the discharge safety accidents are frequent, the production cannot be produced in rainy days, the easy-to-explode tube is unsafe, the production cycle is long, the manufacturing cost is high, the management is cumbersome, and the demand for labor is large. [0003] Today, with the continuous development of my country's agricultural economy, the extensive development model...
