Problems solved by technology

Black gunpowder is a mixture of potassium nitrate, charcoal and sulfur. It is easy to ignite and has high sensitivity. During the production and transportation process, safety accidents are more likely to occur. At the same time, due to the sulfur contained in the components, sulfur dioxide will be produced during discharge to pollute the atmosphere, which is not good for the human body. healthy
In addition to black powder, colleagues in the fireworks industry have also developed some substitutes for black powder in recent years. However, due to the immature formula and production process, the effect of popularization and application is often not ideal.

Embodiment 1

[0027] Embodiment 1: In this example, the ratio of parts by weight of the propellant is 65 parts of potassium perchlorate; 3 parts of phenolic resin; 4 parts of terephthalic acid, 10 parts of potassium hydrogen terephthalate, and 15 parts of carbon powder; 0.5 parts of magnesium oxide, 0.5 parts of graphite, and 2 parts of calcium stearate. Described charcoal powder is the best with hemp stalk charcoal, followed by Chinese fir charcoal. The preparation method is as follows:

[0028] (1) Potassium perchlorate should be stored separately from other components in different rooms;

[0029] (2) If potassium perchlorate is agglomerated, crush it before use, and sieve it with a sieve of 80 to 100 mesh;

[0030] Phenolic resin, terephthalic acid, potassium hydrogen terephthalate, carbon powder, magnesium oxide, graphite, and calcium stearate are sieved through a sieve of 80 to 100 meshes, and then weighed in proportion, fully mixed and packed into bags for later use;

[0031] (3) W...

Embodiment 2-3

[0037] Embodiment 2-3: The difference with embodiment 1 is that the proportioning of the propellant is different, as shown in the following table (1):

Abstract

The invention discloses a firework propellant composition which is prepared from the following components in parts by weight: 61-66 parts of potassium perchlorate, 6-12 parts of a first composite component, 6-12 parts of a second composite component and 6-12 parts of phenolic resin. The weight part ratio of the phenolic resin is 2-4 parts; the first composite component consists of the following components in parts by weight: 3-7 parts of terephthalic acid, 6-10 parts of potassium hydrogen terephthalate and 14-22 parts of powdered carbon; the second composite component is prepared from the following components in parts by weight: 0.5 to 1 part of magnesium oxide, 0.5 to 2 parts of graphite and 0.5 to 2 parts of calcium stearate. The propellant powder has the characteristics of safety, stability, environmental protection, moisture prevention, high efficiency, saving and easiness in popularization and use.

Description

technical field [0001] The invention relates to a kind of fireworks propellant. Background technique [0002] China is the birthplace of fireworks. For a long time, black gunpowder was mainly used as propellant for making fireworks. Black gunpowder is a mixture of potassium nitrate, charcoal and sulfur. It is easy to ignite and has high sensitivity. During the production and transportation process, safety accidents are more likely to occur. At the same time, due to the sulfur contained in the components, sulfur dioxide will be produced during discharge to pollute the atmosphere, which is not good for the human body. healthy. In addition to black powder, colleagues in the fireworks industry have also developed some substitutes for black powder in recent years. However, due to their immature formula and production process, the effect of popularization and application is often not ideal. Contents of the invention [0003] The object of the present invention is to provide a...
