い。2. Description of the Related Art Conventionally, concrete crushers, explosives and the like to which explosives are applied have been mainly used to destroy fragile bodies such as concrete structures and bedrock. Furthermore,
An expansive crushing agent containing lime etc. as a main component has also been proposed and put on the market. Each of these has advantages and disadvantages. For example, if explosives have a high efficiency of destroying fragile bodies such as bedrock, vibration and noise at the time of destruction are very large depending on the explosives used, and a consumption permit is required to adopt them.
We can't say that we will try it easily by trial and error.

４３８４号公報）。On the other hand, the expansive crushing agent has low vibration and noise at the time of crushing and can be easily adopted without needing a consumption permit, but since the reaction takes a long time to complete, crushing efficiency is poor and the explosives are used. It is far behind the construction method. There is a low-vibration / low-noise crushing agent (Gansizer, manufactured by Nippon Koki Co., Ltd.), which is a non-explosive crushing agent, in order to provide a construction method with excellent construction efficiency by compensating for both of these drawbacks. 20

成して破壊に至らしめるものである。The crushing agent is composed of a composition comprising aluminum, cupric oxide and a decomposition gas generating agent. Here, aluminum is a reducing agent for the thermite agent, and this reacts with cupric oxide, which is the oxidizing agent, to cause a thermite reaction in which a high reaction heat is generated at a high reaction rate and a decomposition gas generating agent is generated. By decomposing in a short time, a pressure equal to or higher than the breaking pressure of the fragile body is instantly generated and the destruction is reached.

ミニウムであることが必要である。Therefore, it goes without saying that the destructive performance of the crushing agent is greatly influenced by the thermite reaction. However, the thermite reaction component aluminum which causes this reaction needs to be very fine aluminum having a large surface area in order to increase the reaction rate or maintain good reactivity.

より著しく性能が劣化してしまうことがある。[0007] Such aluminum having a large surface area is very easily oxidized, and once oxidized, the Thermite reaction does not generate sufficient reaction heat but also its reaction rate is lowered, and the decomposition gas generating agent is sufficiently decomposed. It may fail to destroy the fragile body without being given enough heat. Such changes in the chemical and physical properties of the raw material itself are generally called changes over time, but these changes over time may significantly deteriorate the performance.

The present invention has been made to solve such conventional problems, and an object thereof is a low explosive component composed of a non-explosive component that has good stability over time and is excellent in safety during manufacturing and handling. It is intended to provide a crushing composition which is low in vibration and noise.

By maintaining the performance and adding dust scattering inhibitor to aluminum to make it dedust aluminum, it is possible to improve the safety during manufacturing and handling, and to improve the effect of the antioxidant added to aluminum. The temporal stability of the product can be significantly improved.

It was also confirmed that the performance of the product hardly changed. In the invention of claim 2, aluminum is made into a very fine particle size of 44 μm or less by using polytetrafluoroethylene (PTFE) as a dust scattering inhibitor in an amount of 2% by weight or less. However, it has been found that dust scattering can be surely prevented, and the stability over time of the non-explosive crushed composition is improved by using 1 to 2% by weight of stearic acid or aluminum stearate as an antioxidant.

る。In general, such dedusted aluminum particles are water resistant, and therefore have a property that even if they are thrown into water, the surfaces do not get wet and the water diffuses. Therefore, the size of the particle size can be roughly investigated by a test method for observing the extent to which 1 g of dedust aluminum spreads on the water surface rather than the time-consuming particle size distribution analysis. The fineness of the particle size examined by this method is indicated by an index called a water covering area (WCA). Therefore, the larger this value is, the smaller the particle diameter is.

ある。In the third aspect of the invention, the decomposition gas generating agent is a substance that generates water vapor or the like when high temperature is applied, for example, potassium alum, nickel sulfate or the like, if it is an inorganic compound having water of crystallization in the molecule, thermite. Due to the high temperature of the reaction, water of crystallization is released and instantly released as water vapor. It goes without saying that the decomposed gas is most preferably water vapor that is harmless to the human body. From this point of view, sucrose carried out on the assumption that it would generate a gas relatively harmless to the human body, although having a crushing effect on fragile bodies such as methaaldehyde, burns to combustible materials in the vicinity as described above, There is a drawback that it does not have a sufficient crushing effect.

に酸化防止剤の効果が認められた。On the other hand, according to the reaction rate, the composition of Example 1 to which the antioxidant was added due to the effect of the addition of the antioxidant showed that, as shown in Table 2, the antioxidant was added during the storage period of 1 year. Although there is almost no difference from the composition of Comparative Example 1 which is not added, the reaction rate of the composition of Comparative Example 1 is reduced by 30 to 50 m / sec during the storage period of 1.5 years or more, and the antioxidant is clearly prevented. The effect of the agent was recognized.

再び精秤して減量を測定する。The heating test method will be described with reference to FIG. First, the sample is sufficiently dehumidified and dried in a vacuum dryer at room temperature (not shown). Next, 10 g of the sample 1 is used for the bottom diameter 35
mm, 50 mm in height, and weighed precisely in a glass cylindrical weighing bottle 2 with a lid, and allowed to stand for 48 hours in a dryer kept at 75 ° C.,
Weigh accurately again to measure weight loss.
【００３６】この減量が１００分の１以下であれば、こ

可能となる。As described above, according to the inventions of claims 1 to 3, 1 to 2% by weight of stearic acid / aluminum stearate as an oxidant is added to aluminum composed of fine powder particles.
In addition, it is possible to prevent oxidation of aluminum itself and to suppress dust generated when handling fine powder particles by adding 2% by weight or less of polytetrafluoroethylene.
