Embodiment 1

[0009] Embodiment 1: the preparation of described fireworks cracking powder comprises the following steps:

[0010] Step 1: Preparation of composite aluminum powder, weighing 70 parts of aluminum powder, 19 parts of magnesium carbonate, 10 parts of iron oxide, and 1 part of sodium metabismuthate. The components are sieved and mixed evenly.

[0011] Step 2: Mix the composite aluminum powder prepared in Step 1 with potassium perchlorate evenly in a ratio of 1:2 to obtain the fireworks-effect explosive.

[0012] In use, it is used as a firework explosive according to a known method, and an igniter should be arranged on the effect piece of the fireworks. After the medicine is ignited by the fuse, the firework effect is detonated to open the explosive medicine.

Embodiment 2

[0013] Embodiment 2: The difference from Example 1 is that the weight proportion of each component of the composite aluminum powder is 65 parts of aluminum powder, 21 parts of magnesium carbonate, 9 parts of iron oxide, and 0.7 part of sodium metabismuthate.

Embodiment 3

[0014] Embodiment 3: The difference from Example 1 is that the weight proportion of each component of the composite aluminum powder is 68 parts of aluminum powder, 18 parts of magnesium carbonate, 11 parts of iron oxide, and 1.2 parts of sodium metabismuthate.

Abstract

The invention discloses composite aluminum powder for fireworks bursting charge. The composite aluminum powder comprises components in parts by weight as follows: 65-75 parts of aluminum powder, 17-21 parts of magnesium carbonate, 8-12 parts of ferric oxide and 0.5-1.5 parts of sodium bismuthate. The components are mixed uniformly with a common method. The fireworks bursting charge prepared from the aluminum powder does not contain sulfur and does not contain prohibited chlorate, arsenic compounds, mercury compounds, gallic acid, picric acid, magnesium powder, phosphorus, lead compounds, hexachlorobenzene or fireworks promoters and is an environment-friendly fireworks bursting charge; bursting performance of the fireworks bursting charge is better than that of traditional bursting charge under the same condition; the detection of the National Supervision and Inspection Center for Safety and Quality of Fireworks and Firecracker indicates that friction sensitivity of the composite aluminum powder is 0, impact sensitivity is 0, the ignition temperature is not lower than 410 DEG C, all safety indexes are better than those of the traditional bursting charge, and potential safety hazard is reduced fundamentally; the composite aluminum powder has excellent storage stability.

Description

technical field [0001] The invention relates to a break explosive used for fireworks, in particular to aluminum powder used as a break explosive reducing agent. Background technique [0002] Existing firework detonator is main raw material with potassium perchlorate, alloy powder, sulfur. The disadvantages are that the friction and impact sensitivity are high, and the safety is not guaranteed; at the same time, the environment is polluted. Contents of the invention [0003] In order to solve the above-mentioned disadvantages, the technical problem to be solved by the present invention is to provide a novel reducing agent for fireworks crackers, so as to obtain safe and environment-friendly fireworks crackers. In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is a composite aluminum powder used for fireworks cracking powder, which is characterized in that its components and their weight / number ratios are: 65-7...
