[Prior art] Conventionally, as such a composition, for example, a concrete crusher using explosives (CCR, SLB),
In addition, there is a crushing agent mainly used for the same purpose, such as calcium oxide, as a static crushing agent. [Problems to be Solved by the Invention] However, among these crushing agents, the static crushing agent is several times slower than the explosives described above in the time until the completion of the reaction, and can withstand use in a limited construction period. I can't. In addition, as an agent having a short time to complete the reaction, for example,
Thermite welding agents disclosed in U.S. Pat. Nos. 3,649,390, 3,720,552, 3,726,727, and 3,745,077 are known. As is well known, the thermite composition, when reacted, heats the product to a high temperature of 3,000 ° C. or higher, and melts and bonds the members using this heat. Further, the concrete crusher is subject to various restrictions at the stage of use under the regulations of the Explosives Control Law, and has drawbacks such as difficulty in use. The present inventors have conducted intensive studies as to whether high heat generated during the reaction of the thermite composition can be used to destroy rocks, concrete structures, stones, and the like, and as a result, a thermite composition composed of an oxidizing agent and a reducing agent. When a reaction gas generating agent consisting of at least one of an inorganic compound containing a large amount of water of crystallization and an organic or inorganic compound generating a gaseous product as a reaction product is added, the reaction gas is generated due to the high heat generated by the thermite reaction. By vaporizing and / or burning the agent, it was found that the required amount of gas could be changed according to the purpose of use, and the gas could be used for destruction, and the present invention was completed. [Object of the Invention] The present invention has been made based on such findings, and an object of the present invention is to provide a crushing agent that does not wait for a reaction time by gasifying and expanding components using the exothermic reaction of thermite. Is to do. [Means for Solving the Problems] The crushing composition according to the present invention is a crushing composition comprising an oxidizing agent, a reducing agent, and a reactive gas generating agent, wherein the oxidizing agent is cupric oxide, ferric oxide. Or one or more metal oxides selected from boron oxide; a reducing agent is a powdered metal of aluminum or magnesium; a reactive gas generating agent is KAl (S
O 4 ) at least one agent selected from the group consisting of 2 · 12H 2 O and ammonium persulfate. Here, the mixing ratio of the above-mentioned oxidizing agent, reducing agent and reactive gas generating agent varies depending on the use and purpose, but the oxidizing agent and the reducing agent may be in a range generally used as a thermite agent. Usually, the oxidizing agent is around 77% by weight and the reducing agent around 23% by weight. The reaction gas generating agent is 3-150% by weight when the oxidizing agent and the reducing agent are 100% by weight. The proportions of the respective components as described above were determined based on the experimental results as follows. If the mixing ratio of the reaction gas generating agent is less than 3% by weight, the amount of gasification components generated by high heat due to the thermite reaction is small, and the breaking power is poor. If it exceeds 150% by weight,
It was confirmed that this would hinder the thermite reaction and was undesirable. The crushing agent according to the present invention uses an oxidizing agent, a reducing agent, and a reaction gas generating agent obtained by previously dissolving a small amount of fluororubber, nitrocellulose, or the like in an organic solvent such as acetone, and granulates them. -When dried, it is possible to impart water resistance to the obtained granulated composition. The obtained composition can easily cause a reaction with a red-hot nichrome wire or the like. Further, the crushing agent according to the present invention has a large calorific value and a small gas volume by variously changing the composition,
There is a merit that the calorific value can be arbitrarily adjusted to a small value and a large gas volume, and the composition used can be changed according to the strength of the object to be destroyed. [Action of the Invention] In the present invention, since a reactive gas generating agent is added to the thermite composition, it is gasified by high heat due to the thermite reaction, and is broken by applying heat and gas pressure to the object to be destroyed. I can do it. Examples of the Invention Hereinafter, examples according to the present invention will be described based on Table 1. Experiment No. 1 in Table 1 shows a conventional thermite composition. Experiment Nos. 2 to 10 in Table 1 are crushing agents according to the present invention. As described above, the compounding agents shown in Table 1 are obtained by mixing aluminum or magnesium (reducing agent), copper oxide or iron oxide (oxidizing agent), aluminum alum or ammonium persulfate (reactive gas generating agent) with nitrocellulose. After kneading with (binder), it is granulated to form a crushing agent. Next, the operation procedure is described in Table 1.
Nos. 4 and 6 will be described in detail. In Experiment No. 4, 77% by weight of cupric oxide and 23 aluminum powder were used.
The composition is obtained by adding 100% by weight of aluminum alum to 100% by weight of a thermite agent. As a binder of the present composition, nitrocellulose obtained by dissolving 11% by weight of acetone in acetone was used. The composition obtained in this manner was made into a 15 mm × 40 g cartridge, loaded into a hole drilled in the center of a concrete block of 0.7 m 3 in the cartridge, and ignited when ignited. Was.
At a distance of 30m, almost no sound or vibration was felt. Next, the crushing agent shown in Experiment No. 9 will be described. First, 77% by weight of cupric oxide and 23% by weight of aluminum powder
Is a composition obtained by adding 100% by weight of ammonium persulfate to the thermite agent. As the binder of the present composition, a fluororubber obtained by dissolving 1% by weight of acetone in acetone was used. The composition thus obtained was placed in a cartridge of 25φ × 60 g, loaded into the approximate center of about 3 m 3 of sandstone (elastic wave velocity: 4,000 m / s), and ignited. Broken into pieces. The sound was 65dB at 21m. When rocks of approximately the same size were used with the same amount of slurry explosives, they broke and shattered. The loudness at the 20m point was 105dB. [Effects of the Invention] As described above, the present invention is composed of an oxidizing agent, a reducing agent, and a reactive gas generating agent. Therefore, when the oxidizing agent and the reducing agent cause a thermite reaction, the high heat generated immediately The reaction gas generating agent is gasified, and rocks, concrete structures, stone materials and the like can be destroyed by using the generated gas amount. That is, it is possible to destroy rocks, concrete structures, stones and the like without a reaction waiting time unlike the conventional static crushing agent.
