본 발명은, 콘크리트 구조물· 암반 따위의 취약성체(脆弱性體)를 저진동·저소음으로 순시에 파괴하는 비화약 파쇄 조성물에 관한 것이다.TECHNICAL FIELD This invention relates to the non-powder crushing composition which destroys fragile bodies, such as a concrete structure and rock instantly, with low vibration and low noise.
종래에는, 콘크리트 구조물·암반 따위 취약성체를 파괴하는 데에 화약류의 적용을 받는 콘크리트 파쇄기, 폭약 등이 주로 사용되어 왔다. 나아가서는, 석회 등을 주성분으로 하는 팽창성 파쇄제도 제안되어 시장에 나와 있다.Background Art Conventionally, concrete crushers, explosives, etc., which are subject to explosives, have been mainly used to destroy fragile structures such as concrete structures and rocks. Furthermore, an expansive crushing agent based on lime or the like has been proposed and is on the market.
이들은 모두 일장일단이 있다. 예컨대, 화약류라면 암반 등의 취약성체 파괴효율은 높으나, 파괴시의 진동, 소음은 사용한 화약류에 따라서 매우 크며, 이들의 사용시에는 소비허가가 필요하며, 시행착오로 쉽게 실시하여 볼 수도 없는 것이다.These are all in one piece. For example, if the explosives have a high efficiency of breaking fragile bodies such as rocks, the vibration and noise at the time of destruction are very large depending on the explosives used, and their use requires consumption permission and cannot be easily carried out by trial and error.
한편, 팽창성 파쇄제는, 파쇄시의 진동·소음이 적고, 또한 소비허가도 필요없이 용이하게 채용할 수 있으나, 반응 완결까지의 시간이 길기때문에, 파쇄효율이 불량하여, 상기 화약류를 사용한 시공법에 크게 미치지 못한다.On the other hand, the expandable shredding agent has a low vibration and noise during the shredding and can be easily employed without the need for consumption permission. However, the expansive shredding agent has a long breaking time until completion of the reaction. Not much shorter
이들 양자의 결점을 보완하고, 시공효율이 우수한 시공방법을 제공하기 위한 비화약 파쇄제인 저진동·저소음 파쇄약제(일본공기(주)제 간사이저)가 있다(특개평 2-204384호 공보).There is a low vibration and low noise crushing agent (Kansai Kasei Co., Ltd.) which is a non-powder crushing agent to compensate for these drawbacks and to provide a construction method with excellent construction efficiency (Japanese Patent Application Laid-Open No. 2-204384).
이것은 화약류를 사용한 시공방법과 전적으로 같은 방법으로 소비허가가 필요없고, 신속하게 취약제를 파괴하는 시공법을 제공하는 것으로서, 현장작업원에는 위화감을 주지 않는 우수한 파쇄약제이다.This is an excellent shredding agent that does not require dissipation, and quickly destroys fragile agents in the same way as the construction method using explosives.
상기 파쇄약제는 알루미늄, 산화제이구리 및 분해가스 발생제로서 이루어지는 조성물로 구성되어 있다.The shredding agent is composed of a composition consisting of aluminum, cuprous oxide and a cracking gas generator.
여기에서, 알루미늄은 테르미트제의 환원제이며, 이것과 산화제인 산화제이구리가 반응해서 반응속도가 빠르고, 더욱이 고반응열을 발생시키는 테르미트 반응을 일으켜, 분해가스 발생제를 단시간에 분해하므로써 취약성체의 파괴강도 이상의 압력을 순시에 생성하여 파괴에 이르게 하는 것이다.Here, aluminum is a reducing agent of the termit agent, which reacts with cupric oxide, which is an oxidizing agent, so that the reaction rate is high, and further, the termit reaction that generates high heat of reaction generates a short reaction time to decompose the decomposition gas generating agent in a short time. It creates instantaneous pressure above the breaking strength and leads to breaking.
따라서, 상기 파쇄약제의 파괴성능은 테르미트 반응 여하에 크게 좌우되는 것은 물론이다.Therefore, the destructive performance of the crushing agent is of course greatly influenced by the thermite reaction.
그런데, 이 반응을 발생시키는 테르미트 반응 성분의 알루미늄은 반응속도를 올리기 위하여, 혹은 반응성을 양호하게 유지하기 위하여 매우 미세한, 더욱이 표면적이 알루미늄일 필요가 있다.By the way, the aluminum of the termite reaction component which produces this reaction needs to be very fine, and also surface area aluminum, in order to raise reaction rate or to maintain good reactivity.
이와 같은 표면적이 큰 알루미늄은 매우 산화되기 쉽고, 한번 사노하되면 테르미트 반응은 충분한 반응열을 발생하지 않을 뿐만 아니라 그 반응속도도 저하하며, 분해가스 발생제를 충분히 분해할 만큼의 열량이 부여되지 못하여, 취약성체의 파괴에 실패하는 일이 있다.Aluminum having such a large surface area is very easy to oxidize, and once sano is used, the termit reaction not only generates sufficient heat of reaction, but also lowers the reaction rate and does not provide enough heat to decompose the decomposition gas generating agent. It may fail to destroy the vulnerability.
이와 같이, 원료 그 자체의 화학적·물리적 성상이 변화하는 것을 일반적으로 경시변화라고 하는데, 이 경시변화에 의하여 크게 성능이 열화되어 버리는 일이 있다.As described above, a change in the chemical and physical properties of the raw material itself is generally referred to as a change over time, and the performance may be greatly degraded by this change over time.
또, 전술한 바와 같이, 미분말의 알루미늄을 사용하고 있으므로, 제조시에 분진이 날아서 최악의 경우에는 분진폭발의 위험성마저 존재한다.In addition, as described above, since fine powder aluminum is used, dust is blown during manufacture, and in the worst case, there is even a risk of dust explosion.
본 발명은, 그와 같은 종래의 문제점을 해결하기 위하여 이루어진 것이며, 그 목적은, 경시 안정성이 양호하며, 더욱이 제조시 및 취급시의 안정성이 뛰어난 비화약 성분으로 이루어지는 저진동, 저소음의 파쇄조성물을 제공하는 데 있다.The present invention has been made to solve such a conventional problem, and an object thereof is to provide a low vibration and low noise shredding composition composed of a non-powder component having good stability over time and excellent in manufacturing and handling.

It is characterized by that.
또한, 본 발명의 청구범위 제3항은, 분해가스 발생제가 붕사를 제외한 고온 가열시 수증기 등을 발생시키는 칼륨백반 등 결정수를 가지는 무기물임을 특징으로 하는 것이다.In addition, claim 3 of the present invention is characterized in that the decomposition gas generator is an inorganic substance having crystal water such as potassium alum, which generates water vapor at the time of high temperature heating except borax.
그리고, 청구범위 제1항의 발명에서는, 테르미트제를 입자지름 44㎛ 이하의 미립자를 입도분포로서 95% 이상을 함유하며, 또한 분진 비산 방지제와 산화 방지제를 함유한 알루미늄분 15∼30 중량%, 입자지름 74㎛이하의 미립자를 입도분포로서 95% 이상을 함유하는 산화제이구리 70~80 중량%로서 이루어지는 것으로 하였으므로, 종래의 비화약 파쇄약제와 동등 이상의 연소성 및 취약성체 파괴성능을 유지하며 또한 알루미늄에 분진 비산 방지제를 첨가함으로써 디더스트 알루미늄으로 하였으므로, 제조시 및 취급시의 안정성을 향상시킬 수가 있음과 동시에, 알루미늄에 첨가한 산화방지제의 효과에 의하여 제품의 경시 안정성을 크게 향상시킬 수가 있다.In the invention according to claim 1, 15-30% by weight of an aluminum powder containing a termit agent containing 95% or more of fine particles having a particle diameter of 44 μm or less as a particle size distribution, and containing a dust scattering agent and an antioxidant, Since the fine particles having a particle diameter of 74 µm or less are composed of 70 to 80% by weight of copper oxide containing 95% or more as the particle size distribution, it maintains the combustibility and fragility destruction performance equivalent to that of conventional non-powder crushing agents and By adding a dust scattering agent to make it dust aluminum, the stability at the time of manufacture and handling can be improved, and the time-lapse stability of a product can be improved significantly by the effect of the antioxidant added to aluminum.
여기에서, 알루미늄의 입도를 44㎛ 이하(메디안 17~23㎛)의 것으로 하는 테르미트 반응의 산화제인 산화제이구리는, 종래보다 입자지름을 크게 하여도 비화약 파쇄 조성물의 성능은 거의 변하지 않는 것도 확인하였다.Here, it is also confirmed that the copper oxide, which is an oxidizing agent of the termite reaction having an aluminum particle size of 44 μm or less (median 17 to 23 μm), hardly changes the performance of the non-powder crushing composition even if the particle size is larger than before. It was.
또, 청구범위 제2항의 발명에 있어서는, 알루미늄은, 분진 비산 방지제로서 폴리테트라플루오로에틸렌(PTFE)을 2 중량% 이하의 범위에서 사용하므로써 알루미늄의 입도가 44㎛ 이하인 매우 미세한 입자지름으로 하여도 분진의 비산을 확실하게 방지할 수 있음을 알게 된 것이며, 산화 방지제로서 스테아린산 또는 스테아린산 알루미늄을 1~2 중량% 사용하므로써 비화약 파쇄 조성물의 경시 안정성을 향상시킨 것이다.In the invention according to claim 2, even when aluminum is used as a dust scattering agent, polytetrafluoroethylene (PTFE) is used in a range of 2% by weight or less, even if the aluminum has a very fine particle diameter of 44 µm or less. It has been found that dust scattering can be prevented reliably and by using 1 to 2% by weight of stearic acid or aluminum stearate as an antioxidant, the stability over time of the non-powder crushing composition is improved.
일반적으로, 이와 같은 미립자의 디더스트화한 알루미늄은 내수성이며, 따라서, 수중에 투입하여도 표면이 젖지 않고 수면으로 확산하는 성질이 있다. 그 때문에, 시간이 걸리는 입도 분포 분석보다도 1g의 디더스트 알루미늄이 수면상에 어느 정도의 면적으로 퍼지는가를 보는 시험방법에 의해서 그 입도의 크기를 대략 조사할 수가 있다. 이 방법으로 조사한 입경의 작은 정도를 워터 커버링 에리어(W.C.A)라는 지표로 표시한다. 따라서, 이 값이 클수록 입자 지름이 작은 것을 의미한다.In general, the dedusted aluminum of such fine particles is water resistant, and therefore, even when introduced into water, the surface does not get wet and has a property of diffusing to the water surface. Therefore, the size of the particle size can be roughly investigated by a test method which shows how much area 1 g of dust aluminum spreads on the surface of the water rather than time-consuming particle size distribution analysis. The small extent of the particle size investigated by this method is indicated by the index of a water covering area (W.C.A). Therefore, larger value means smaller particle diameter.
또한, 청구범위 제3항의 발명에서는, 분해가스 발생제는 고온을 부여하면 수증기 등을 발생시키는 물질, 즉 칼륨백반, 황산니켈 등의 분자내에 결정수를 가지는 무기화합물이라면, 테르미트 반응의 고온에 의해서 결정수가 해방되어 순시간에 수증기로서 방출되게 한다. 바람직하게는 이 분해가스가 인체에 무해한 수증기라면, 가장 바람직한 것임은 물론이다.In addition, in the invention of claim 3, the decomposition gas generating agent is a substance which generates water vapor or the like when a high temperature is applied, i.e., an inorganic compound having crystal water in a molecule such as potassium alum, nickel sulfate, or the like. This frees the crystal water and allows it to be released as water vapor in a short time. Preferably, if the cracked gas is water vapor harmless to the human body, it is of course the most preferable one.
이 관점에서, 비교적 인체에 무해한 가스를 발생시킬 것이라고 상정하여 실시한 사탕수수, 메타알데히드 등도 취약성체의 파쇄효과가 있기는 하나, 앞서 기재한 대로, 부근의 가연물에 연소가 미치거나 충분한 파쇄효과를 가지지 못한다는 결점이 있다.From this point of view, sugar cane, metaaldehyde, etc., which are assumed to generate relatively harmless gas to the human body, also have a crushing effect of the fragile body, but as described above, combustion does not occur or have sufficient crushing effects on nearby combustibles. There is a flaw.

또한, 1 년간 저장 후, 이 조성물의 연소속도를 계측한바, 215m/sec, 다시 2년간 저장 후에는 215m/sec 로서 거의 변화가 없었다.In addition, after storage for one year, the burning rate of the composition was measured, and after 215 m / sec, after two years of storage, there was almost no change as 215 m / sec.
이 연소속도는 콘티나이트로사제의 광파이버 폭발속도 측정기(EXPLOMET-FO)를 사용하여 계측하였다.This combustion rate was measured using the optical fiber explosion rate measuring instrument (EXPLOMET-FO) by Continite.

[실시예 6]Example 6
실시예 4와 같은 배합이나, 칼륨백반 대신에 암모늄백반(다이메이 화학(주)제)를 사용하였다.The same compound as in Example 4 or ammonium alum (manufactured by Daimei Chemical Co., Ltd.) was used instead of potassium alum.
[실시예 7]Example 7

[실시예 8]Example 8
실시예1과 같은 배합이나, 칼륨백반 대신에 암모늄백반을 사용하였다.The same formulation as in Example 1, but ammonium alum was used instead of potassium alum.
실시예 1~8 은 본 발명의 주 취지에 맞으며, 우수한 성능, 취급성을 가지고 있으나, 그 중에서도 실시예 8은 성능면에서 뛰어남을 알 수 있었다.Examples 1 to 8 meet the main gist of the present invention and have excellent performance and handleability, but among them, Example 8 was found to be excellent in performance.
[비교예 1]Comparative Example 1
분진 방지제, 산화 방지제가 함유되어 있지 않은 입자 지름 44㎛ 이하의 알루미늄분 23 중량부에 아세톤 10 중량부를 가하고, 다시 입자지름 44㎛ 이하의 산화제이구리 77 중량부를 가하여 잘 혼합하였다.10 parts by weight of acetone was added to 23 parts by weight of aluminum powder having a particle diameter of 44 μm or less, which contained no dust inhibitor and antioxidant, and then 77 parts by weight of copper oxide having a particle size of 44 μm or less was added and mixed well.
다음에, 바인더액에 12 중량부를 앞서의 알루미늄분과 산화제이구리의 혼합물에 가하고, 다시 잘 혼합하였다. 다음에, 칼륨백반 100 중량부를 가하고, 다시 잘 혼합하였다.Next, 12 parts by weight of the binder liquid was added to the mixture of the aluminum powder and the copper oxide described above, and the mixture was mixed well again. Next, 100 parts by weight of potassium alum were added and mixed well again.
이 혼합물은, 다음에 JIS 표준 8메시 채를 통과시켜, 12시간 바람에 건조시켰다. 이 중, 시료 약 250g 빼서, 내경 27mm, 길이 400mm 의 플라스틱 통체에 충전하고, 전용의 착화기구를 장착한 후, 그 연소속도를 계측한 바, 215m/sec였다.This mixture was then passed through a JIS standard 8 mesh shaft and dried in a wind for 12 hours. Among them, about 250 g of the sample was taken out and the inner diameter 27 It was 215 m / sec when the combustion speed was measured after filling in the plastic cylinder of mm and 400 mm in length, and attaching the exclusive ignition mechanism.
또한, 1년간 저장 후, 이 조성물의 연소속도를 계측한 바, 208m/sec 이며, 다시 2년간 저장 후에는 166m/sec라는 현저한 성능의 열화가 보였다.After storage for one year, the burn rate of the composition was measured and found to be 208 m / sec, and after two years of storage, a remarkable deterioration of 166 m / sec was observed.
[비교예 2]Comparative Example 2
실시예 1과 같은 배합이나, 칼륨백반 대신에 붕사(Na2B4O7·10H2O)를 사용하였다.Borax (Na 2 B 4 O 7 · 10H 2 O) was used in the same formulation as in Example 1, but in place of potassium alum.
마찬가지로 하여, 플라스틱 통체에 충전하고, 연소속도를 잰 바, 130m/sec였다.Similarly, it filled in the plastic cylinder and measured the combustion speed, and it was 130 m / sec.
이 조성물은 1년 후에는 부분적으로 고화되었으므로, 경시안정성이 불량한 것을 알았다.Since this composition was partially solidified after one year, it was found to be poor in time stability.
[비교예 3]Comparative Example 3
분진방지제로서 PTFE가 2중량부, 산화 방지제로서 스테아린산 2, 3 중량부를함유하는 입자지름 44㎛ 이하의 알루미늄분 23 중량부에 입자지름 44㎛ 이하의 산화제이구리 77 중량%를 가하고, 다시 바인더액 12 중량부와 사탕수수 100 중량부를 가하여 잘 혼합하였다. 그후, JIS 규격 8 메시 채를 통과시켜, 12 시간 바람에 건조시켰다.77 weight% of copper oxide with a particle diameter of 44 micrometers or less was added to 23 weights of aluminum powders with a particle diameter of 44 micrometers or less containing 2 parts by weight of PTFE as the dust inhibitor and 2 or 3 parts by weight of stearic acid as the antioxidant, and again, binder solution 12 100 parts by weight of sugar and 100 parts by weight of sugar cane were added and mixed well. Thereafter, the JIS standard 8 mesh cloth was passed through and dried in a wind for 12 hours.
이것을 실시예 1과 같은 방법으로 하여 연소 속도를 계측한 바, 185m/sec였다. 이 조성물은, 연소잔사가 언제까지나 그을려지는 경향이 있으며, 부근에 가연물이 있으면, 연소가 번지는 위험성이 있음을 알았다.When the combustion speed was measured in the same manner as in Example 1, it was 185 m / sec. It was found that this composition tends to be burned forever, and there is a risk of combustion spreading if flammables are present in the vicinity.
[비교예 4][Comparative Example 4]
비교예 3과 같은 배합이나 사탕수수 대신에 메타알데히드(시약)를 사용하였다. 마찬가지로 하여, 플라스틱 통체에 충전하고 연소속도를 측정한 바, 100m/sec라는 낮은 값이며, 다소 미반응물이 보였다.Metaaldehyde (reagent) was used instead of the same formulation as in Comparative Example 3 or sugar cane. Similarly, the plastic cylinder was filled and the combustion rate was measured. As a result, a low value of 100 m / sec was observed, and somewhat unreacted material was observed.
그래서, 본 시료를 석면 상에 펼치고 다른 착화구로 연소시킨 결과, 흰 섬유상의 부유물이 발생하고, 반응가스도 특이한 냄새를 풍긴다는 것을 알았다.Therefore, as a result of spreading the sample on asbestos and burning it with another ignition sphere, it was found that a white fibrous suspension was generated, and the reaction gas also had a unique smell.
다음에, 상술한 실시예 및 비교예의 결과를 표 1에 나타낸다.Next, Table 1 shows the results of the above-described examples and comparative examples.
표 1에서, 스테아린산/동알루미란, 스테아린산 또는 스테아린산 알루미늄 중 어느 하나라는 의미이다.In Table 1, stearic acid / copper alumina means either stearic acid or aluminum stearate.
경시 안정성에 관해서는, 그 정도를 5개 랭크로 나누어서 수치로 표시하였으나, 제조/취급 안전성에 관해서는, / 기호로 나누어서 랭크를 붙여 표시하였다.As for the stability over time, the degree was divided into five ranks, and the numerical value was expressed. However, the manufacturing / handling safety was divided by the / symbol to indicate the rank.
마찰·낙추(落追) 감도는, 각각 7급·8급까지 있으며, 수치가 클수록 둔감하다는 것을 나타낸다.The friction and fall sensitivity are up to Class 7 and Class 8, respectively, indicating that the larger the value, the lower the sensitivity.
[표 1]TABLE 1
단, 경시 안정성과 제조/취급 안전성의 항목은, 5개 랭크(1;불량, 2; 다소 불량, 3; 보통, 4; 다소양호, 5; 양호)로 나누었다.However, the items of stability over time and manufacturing / handling safety were divided into five ranks (1; poor, 2; somewhat poor, 3; moderate, 4; somewhat good, 5; good).
또, PTFE 와 스테아린산/동알루미는 알루미늄 100 중량%에 대한 추가 중량부이다.In addition, PTFE and stearic acid / copper aluminum are additional parts by weight based on 100% by weight of aluminum.
다음에, 분진 비산 방지제의 효과와 산화방지제의 효과에 관하여 설명한다.Next, the effect of the dust scattering inhibitor and the effect of the antioxidant will be described.
분진 비산방지제의 첨가효과에 의해서, 원료의 평량(枰量)공정 및 혼화공정에서 분진이 거의 날리지 않으므로, 금속분에 의한 정전기 발화사고의 위험성이 적어질 뿐만 아니라, 그 분진이 인체에 흡수되는 확률이 감소되므로, 대규모의 배기 장치도 필요없게 되어 작업환경이 크게 개선된다.Due to the added effect of the anti-dust scattering agent, since the dust is hardly blown in the basis weight process and the mixing process of the raw materials, the risk of electrostatic ignition by metal powder is reduced, and the probability that the dust is absorbed by the human body As a result, the large-scale exhaust system is not required and the working environment is greatly improved.
한편, 산화 방지제의 첨가효과에 의해서, 산화 방지제를 첨가한 실시예 1의 조성물을 반응속도 검토하면, 제2도와 같이 1년간의 보존기간에 산화 방지제를 첨가하지 않는 비교예 1의 조성물과 거의 변화는 없으나, 1.5 년 이상의 보존기간에서는 비교예 1의 조성물 쪽이 30~50m/sec의 반응속도 저하가 보이고, 분명히 산화 방지제의 효과가 보였다.On the other hand, when the reaction rate of the composition of Example 1 to which the antioxidant was added was examined by the effect of adding the antioxidant, it was almost changed from the composition of Comparative Example 1, in which the antioxidant was not added during the one-year storage period as shown in FIG. However, in the storage period of 1.5 years or more, the composition of Comparative Example 1 showed a decrease in reaction rate of 30 to 50 m / sec, clearly showing the effect of the antioxidant.
[표 2]TABLE 2
또, 화약류 취체법에 명시되어 있는 안정도 시험 중, 고온 환경 시험인 가열시험에서는 제 3표와 같이 35% 정도의 안정성이 개선되었다.Also, among the stability tests specified in the explosives blowing method, in the heating test, which is a high temperature environmental test, the stability of about 35% was improved as in Table 3.
[표 3]TABLE 3
여기에서, 제1도에 의거 가열시험방법을 설명한다.Here, the heating test method will be described based on FIG.
우선, 시료를 도시하지 않은 상온의 진공건조기 내에서 충분히 제습(際濕)건조시킨다. 다음에, 10g의 시료(1)를 저면 지름 35㎜, 높이 50㎜의 덮개가 달린 유리제 원통형 평량(枰量)병(2)으로 정밀하게 달아서 75℃로 유지한 건조기 내에 48시간 정치한 후, 다시 정밀하게 감량을 측정한다.First, the sample is sufficiently dehumidified in a vacuum dryer at room temperature (not shown). Next, 10 g of the sample 1 was precisely weighed with a glass cylindrical basis weight bottle 2 having a lid of 35 mm in diameter and 50 mm in height, and allowed to stand for 48 hours in a dryer maintained at 75 ° C. Measure weight loss precisely again.
이 감량이 100분의 1 이하이면, 이 시료(1)는 우량이라고 인정하는 방법으로 실시하였다.When this loss was one-hundredth or less, this sample 1 was implemented by the method recognized as excellent.
이상과 같이, 청구범위 제1항∼제3항의 발명에 의하면, 미분입자로 이루어지는 알루미늄에 산화제로서 스테아린산/스테아린산 알루미늄을 1∼2중량%를 가하여 알루미늄 그 자체의 산화를 방지하고, 또한 2중량%의 이하의 폴리테트라플루오로에틸렌을 가하므로써 미분입자를 취급시에 생기는 분진을 억제하는 것이 가능하게 된다.As described above, according to the invention of claims 1 to 3, 1 to 2% by weight of stearic acid / aluminum stearate as an oxidizing agent is added to aluminum made of finely divided particles to prevent oxidation of the aluminum itself, and further 2% by weight. By adding the following polytetrafluoroethylene, it becomes possible to suppress dust generated when handling fine particles.
이 결과, 알루미늄의 입자지름을 44㎛ 이하로 하여도 분진이 별로 날리지 않으며, 이 미세한 알루미늄을 사용함으로 인하여, 산화제이구리의 입자지름이 다소 거친 입자로 되어도 반응 속도에 영향이 없다.As a result, even if the particle diameter of aluminum is 44 micrometers or less, dust does not fly very much. By using this fine aluminum, even if the particle diameter of a cuprous oxide becomes a rather rough particle, it does not affect reaction rate.
