Integrally formed combined firework and manufacturing method thereof

Abstract

The invention discloses an integrally formed combined firework and a production method thereof. The integrally formed combined firework is primarily formed through foaming and mold pressing by takingshredded paper, cassava starch and water as raw materials. The raw materials comprise the following components including, by weight, 14-18 parts of shredded paper, 9-12 parts of cassava starch, 42-46parts of water and 1-5 parts of talc powder. The integrally formed combined firework disclosed by the invention has the beneficial effects that the components are single and uniform in inner structure, and the product is high in structural strength, high in compressive resistance and good in forming property, and the specifications of the product are not limited; the inner wall of a product emitting cavity is high in surface smoothness, the launching resistance is small, the launching height is higher with same explosive quantity, the powder is saved, and the firework is good in economical benefit and safety; the inner diameter of the launching cavity is standard, the height is in order and uniform, the follow-up operation like charging is normal and convenient, and the firework is suitable for standardized and mechanical production; the firework can be fully recovered with a low cost and is good in environment-friendliness; the production step is simplified, the production efficiencyis increased, and the labor force is saved.

Description

technical field [0001] The invention relates to a combined firework and a manufacturing method thereof, in particular to a combined firework whose launch tube is integrally formed at one time and a manufacturing method thereof. Background technique [0002] According to the traditional manual process, the production of combined fireworks requires dozens of processes from paper cutting to finished product, such as paper cutting, gluing, rollers, edge trimming, drying, bottoming, arranging into strips, drilling, arranging, assembling basin etc. Production efficiency is low, and product specifications are difficult to standardize. Under the social background of increasing labor costs, in the prior art, the combined fireworks formed by the launch tube as a whole has partially replaced the traditional craft. The multiple launch tubes (also known as outer tubes) of the combined fireworks are molded as a whole, which greatly improves the production efficiency. [0003] However, ...

Problems solved by technology

[0003] However, the existing integral molding composite fireworks materials are mixed with various fillers such as kaolin, and the pulp only plays the role of reinforcing ribs, and its structural strength is not high. When it exceeds, the finished product may crack; and it will cause the product to be too heavy, which will bring inconvenience to the product transportation and limit the finished product specification; at the same time, it is difficult to fully recycle the existing products, increasing the pressure on environmental protection
