Problems solved by technology

However, this kind of launch tube is also not resistant to long-term high-temperature burning, and can only be used for products such as combined fireworks. When it is fired, the tube body only needs to withstand the short-term high temperature test at the moment of launch.

Embodiment 1

[0022] Embodiment 1: the cylinder body and the fire port of the scorching-resistant fireworks flame-throwing tube are an integrated structure of molding; the raw materials of the molding include the following components by weight: 50 parts of soil, 4 parts of water, 37 parts of phenolic resin, 18 parts of polyvinyl alcohol, and 8 parts of natural resin.

[0023] Among the above components, the soil is dried and pulverized into powder, such as 80-120 mesh. Then dry mix with other components evenly, add water while stirring and mix evenly to form a billet, put the billet into the mold under normal temperature pressure molding, demould to get the finished product. Pressurization can use pressurized equipment, such as a 2-ton hydraulic press. The finished product of the fireworks torch can be applied to the fireworks.

Embodiment 2-7

[0024] Embodiment 2-7: the difference from embodiment 1 is that the components and weight ratios of the raw materials of compression molding are different, as shown in the following table:

Abstract

The invention discloses a burning-resistant firework flaming barrel. A barrel body and a flaming opening are of an integrated structure formed through compression molding. Raw materials for compression molding comprise the following components: soil, water, phenolic resin, polyvinyl alcohol and natural resin; the components are uniformly mixed to form a blank, and the blank is put into a mold to be pressurized and formed at normal temperature, and is demolded. The firework flaming tube with soil as a main body can be manufactured; the manufacturing method is simple, the cost is low, manufacturing is convenient and easy, and the manufactured barrel can resist long-time high-temperature burning and has no risk of barrel burning or barrel explosion. The set-off duration of the firework product is not limited by the barrel body factor any more, and the firework product can be used at will within the explosive loading range allowed by the safety regulation. The manufactured barrel is good in moisture resistance, not ignited and high in structural strength, the inner wall of the barrel is smooth, smoke pollution caused by firework setting-off is effectively reduced, and the situation that the setting-off effect is shielded by smoke is avoided.

Description

technical field [0001] The present invention relates to a firework component, in particular to a firework tube or a firework tube. Background technique [0002] Sprinkler fireworks and some toy fireworks (mainly rotating and rotating lift-off) all form the corresponding discharge effect by spraying the combustion airflow of pyrotechnic powder from the firework tube or firework tube. Therefore, these firework tubes or firework tubes are called firework torches. [0003] In the prior art, the fireworks and torches are all rolled paper cylinders, and the shapes of the cylinders include cylindrical cylinders (also known as straight cylinders), conical cylinders or other special-shaped cylinders. The cylinder is filled with pyrotechnic powder, the port is sealed with a mud head made of mud, and the central opening of the mud head is used as a crater. After the spray-type fireworks are ignited through the external lead, the pyrotechnic powder in the cylinder is burned to form a ...
