Description

고탄성 경화용 조성물{High-elasticity hardening composition}[0001] The present invention relates to a high-elasticity hardening composition,

본 발명은 토사, 산업폐기물, 해사, 및 사막모래 경화용 조성물 및 그를 포함하는 경화체 조성물에 관한 것이다.The present invention relates to a composition for soil, industrial waste, marine, and desert sand hardening, and a cured composition comprising the same.

근래 들어 토목공사 및 건설사업 등의 수행 시 양질의 건설재료 확보 어려움으로 인해 공사기간이 지연되어 경비를 증가시키는 요인으로 작용하며, 건설자재 확보를 위하여 석산 개발을 하거나 하천, 해상 등에서 골재채취를 함으로써 자연환경을 훼손하고 생태계를 교란시키는 문제가 야기되고 있다.In recent years, construction work has been delayed due to difficulty in securing high-quality construction materials during construction work. This is a factor that increases expenses. In order to secure construction materials, it is necessary to develop stone- The problem is that it damages the natural environment and disturbs the ecosystem.

구체적으로는, 기존 항만매립 공법, 기존 아스팔트 및 콘크리트 포장공법 등에서는 석재 등의 입상재료를 사용하므로 채석을 위하여 산야를 훼손하고 있고, 채석, 운반, 깨기 작업이 공사비를 증가시키는 요인이 되고 있다. Concretely, the existing harbor landfill method, conventional asphalt and concrete pavement methods use granular materials such as stones, so they are damaging the mountainside for the purpose of quarrying, and quarrying, transportation and breaking work are increasing factors for construction cost.

상기와 같은 문제점을 해결하기 위하여 우리나라 전역에 널리 분포되어 있는 토사, 산업폐기물, 하천준설 오니, 해사, 사막모래 등을 각종 토목공사 및 기타 건설 사업에 석재 대용으로 재활용하기 위한 방안이 요구되고 있다.In order to solve the above problems, there is a demand for a method for recycling soil, industrial waste, river dredging sludge, marine sand, and desert sand widely distributed throughout Korea to stone construction and other construction projects.

이러한 방안으로서, 종래에 시멘트 안정처리공법(Cement stabilization), LAC(Lignin Rosin Asphalt Concrete) 공법 등이 개발되어 활용되고 있으나, 마무리 양생시간이 길어 조기 압축강도를 얻기 힘들며, 압축강도 또한 30kgf/㎠ 이하로 낮아 사용할 수 있는 분야가 도로건설의 보조 기층재 등에 국한되어 있어서 활용성이 매우 낮았다.Conventionally, cement stabilization and lignin rosin asphalt concrete (LAC) techniques have been developed and utilized. However, it is difficult to obtain early compression strength due to a long curing time and a compression strength of 30 kgf / cm 2 or less And the application area is low because it is limited to the subbase materials of road construction.

대한민국 특허공개 제10-1996-29280호는 경화제 조성물을 사용하여 산업폐기물 및 토양 혼합물을 경화하는 방법을 개시하고 있다. 이때 사용된 경화제 조성물은 탄산나트륨 25%, 염화가리 25%, 탄산마그네슘 15%, 염화암모늄 10%, 규산화가리 8%, 실리케이트 7%, 황산철 5% 및 산화티탄 5%를 포함하도록 구성되어 있다. 이 경화제는 산업폐기물과 토양의 혼합물을 경화하기에 적합한 조성으로 기재되어 있으나, 탄산나트륨과 산화티탄을 주성분으로 사용함으로써 제조비용이 고가이며 이를 사용하여 제조되는 경화체의 강도 또한 크게 향상되지 못하는 단점이 있었다.Korean Patent Publication No. 10-1996-29280 discloses a method of curing an industrial waste and soil mixture using a curing agent composition. The curing agent composition used herein was composed of 25% sodium carbonate, 25% chlorine dioxide, 15% magnesium carbonate, 10% ammonium chloride, 8% silicic acid, 7% silicate, 5% iron sulfate and 5% titanium oxide. This curing agent is described as a composition suitable for curing a mixture of industrial waste and soil. However, since sodium carbonate and titanium oxide are used as main components, the manufacturing cost is high and the strength of the cured product manufactured using the curing agent is not greatly improved .

상기 식에서 R1 및 R2는 각각 독립적으로 수소 또는 메틸기이며, m과 n은 몰분율로서 m은 0.3~0.7이며, n은 0.3~0.7이며, m + n = 1이다.Wherein m and n are molar ratios, m is 0.3 to 0.7, n is 0.3 to 0.7, and m + n = 1.

상기 화학식 1로 표시되는 화합물은 말단에 포스포산을 포함하고 있어서 경화용 조성물의 응고기능을 향상시키며, 트리메톡시실란기를 포함하고 있어서 유무기 물질 간의 결합력을 향상시킨다. 또한 중량평균분자량이 50,000~100,000이므로 경화용 조성물과 다른 성분들 간의 결합을 강하게 하는 기능을 수행한다. 1 중량부 미만으로 포함되는 경우에는 목적하는 효과를 달성하기 어려우며, 5 중량부를 초과하는 경우에는 추가적이 효과 향상에 의한 이점보다 경제적인 단점이 더 커서 바람직하지 않다.The compound represented by the above formula (1) contains phosphoric acid at the end to improve the solidifying function of the curing composition and contains a trimethoxysilane group, thereby enhancing the bonding force between the organic materials. In addition, since the weight average molecular weight is 50,000 to 100,000, it functions to strengthen the bond between the curing composition and other components. If it is contained in an amount of less than 1 part by weight, the desired effect is difficult to achieve, and if it exceeds 5 parts by weight, it is not preferable because it is more economical than the advantage by further improving the effect.

상기 염화나트륨(Sodium chloride)은 무색결정으로 마그네슘 등의 염류를 함유하며 조해성이 있다. 나트륨염의 제조원료로서 시멘트의 수화 반응을 촉진시키는 역할을 한다. 1 중량부 미만의 양으로 함유될 경우 수분과의 원활한 수용이 되지 않아 수화열이 높게 발생하여 경화체 구체에 균열을 유발할 수 있으며, 3 중량부의 양으로 함유될 경우 시멘트의 원활한 포졸란 반응을 억제하여 강도 구현에 문제점이 야기될 수 있다.Sodium chloride is a colorless crystal containing salts such as magnesium and is decomposable. It serves to promote the hydration reaction of cement as a raw material for production of sodium salt. If it is contained in an amount of less than 1 part by weight, it can not be smoothly accommodated with moisture, so that a high heat of hydration occurs to cause cracks in the cured body, and when contained in an amount of 3 parts by weight, the smooth pozzolanic reaction of the cement is suppressed A problem may arise.

상기 알루미늄 트리스(O-에칠포스포네이트)는 금속 이온을 봉쇄하는 성질이 있고 응고제 역할을 한다. 0.5 중량부 미만의 양으로 함유될 경우 경화체의 강도 개선에 도움을 주기 어려우며, 1 중량부를 초과하는 경우에는 경제성이 결여되고 환경에 바람직하지 않다. The aluminum tris (O-chile phosporate) has a property of blocking metal ions and acts as a coagulant. If it is contained in an amount of less than 0.5 parts by weight, it is difficult to improve the strength of the cured product, and when it exceeds 1 part by weight, economical efficiency is not obtained and it is not preferable to the environment.

상기 염화칼륨(Potassium chloride)은 흰색의 정방정계에 속하는 결정으로 공업적으로 칼륨염의 제조 원료로 사용되며 흡수성이 강한 성질이 있어서 감수제로 사용된다. 1 중량부 미만의 양으로 함유될 경우 경화체의 경화속도 및 양생 시간을 늦추어 공기에 영향을 주며, 3 중량부 초과의 양으로 함유될 경우 시멘트의 원활한 포졸란 반응을 억제하여 강도 구현에 문제점이 있을 뿐만 아니라 경화체의 조기 경화로 시공 품질의 저하를 가져 올 수 있다. Potassium chloride is a white tetragonal crystal which is industrially used as a raw material for producing potassium salts and has a strong water absorbing property and is used as a water reducing agent. If it is contained in an amount less than 1 part by weight, the curing speed and the curing time of the cured product are delayed to affect the air, and when the curing agent is contained in an amount exceeding 3 parts by weight, a smooth pozzolanic reaction of the cement is inhibited, But it may lead to deterioration of the construction quality due to premature curing of the hardened body.

상기 염화칼슘(Calcium chloride)은 시멘트와 혼합하여 흡수성을 촉진하고 동결을 방지하는 촉매제 역할과 응고제 역할을 한다. 1 중량부 미만의 양으로 함유될 경우 수분과의 원활한 수용이 되지 않아 동결 방지효과가 약하게 되는 문제점이 있을 수 있으며, 2.5 중량부 초과의 양으로 함유될 경우 무수물이 다량 발생하여 경화제가 수분과 만났을 때 액상을 이루기 어려운 문제점이 있을 수 있다.The calcium chloride is mixed with cement to promote the absorbency and serve as a catalyst and a coagulant to prevent freezing. If it is contained in an amount of less than 1 part by weight, it may not be smoothly accommodated with moisture, resulting in a problem of weakening the effect of preventing freezing. When the content is more than 2.5 parts by weight, a large amount of anhydride occurs, There is a problem that it is difficult to form a liquid phase.

상기 산화마그네슘은 응고제의 기능을 수행한다. 0.2 중량부 미만으로 포함되면 목적효과를 제공하기 어려우며, 2 중량부를 초과하는 경우 MgO 일부는 페리클레스(periclase, MgO로부터 구성된 광물)로서 클링커 중에 생성하게 되는 문제가 야기된다. The magnesium oxide functions as a coagulant. If it is contained in an amount of less than 0.2 part by weight, it is difficult to provide a desired effect, and when it exceeds 2 parts by weight, a part of MgO is generated in a clinker as a periclase (mineral composed of MgO).

상기 황산나트륨(Sodium sulfate)은 비교적 안정한 무색의 결정으로 유리나 황화 나트륨의 제조에 쓰인다. 경화체 반응에서는 토사 중의 유기물 건조에 사용된다. 0.2 중량부 미만의 양으로 함유될 경우 시멘트의 원활한 수화작용(포졸란 반응)응 충분히 수행치 못하게 하여 강도에 문제점이 있을 수 있으며, 1.5 중량부 초과의 양으로 함유될 경우 수화작용 향상에는 도움이 되지만 제품비용을 증대시킬 수 있다. Sodium sulfate is a relatively stable colorless crystal used in the manufacture of glass or sodium sulphide. In curing reaction, it is used to dry organic matter in soil. If it is contained in an amount of less than 0.2 part by weight, the hydration action of the cement (pozzolanic reaction) may not be sufficiently performed, and there may be a problem in strength. If the amount exceeds 1.5 parts by weight, The product cost can be increased.

상기 Na2SiO3 0.2~2 중량부 알칼리화이다. 0.2 중량부 미만으로 포함되면 목적효과를 얻기 어려우며, 2중량부를 초과하면 알칼리도가 너무 증가하여 문제가 될 수 있다.0.2 to 2 parts by weight of the Na 2 SiO 3 is alkalized. If it is contained in an amount of less than 0.2 part by weight, it is difficult to obtain a desired effect, and if it exceeds 2 parts by weight, alkalinity may be excessively increased.

상기 리그닌술폰산염(Sodium lignosulfonate)은 토사, 산업폐기물, 하천준설 오니 및 해사와 사막모래, 시멘트 등의 혼합물질을 감수, 분산시키는 역할을 하며 시멘트와 혼합물질을 결합하여 강도를 증대시킨다. 0.2 중량부 미만의 양으로 함유될 경우 입자분산을 저해하며 재료의 완성 후 강도를 저하시키는 문제점이 있을 수 있으며, 1 중량부 초과의 양으로 함유될 경우 재료의 특성상 3차원 망상구조이므로 다른 물질의 화학적 반응을 저해하는 문제점이 있을 수 있다. Sodium lignosulfonate plays a role in reducing and dispersing mixed materials such as sand, industrial waste, river dredged sludge, marine sand, desert sand and cement, and enhances the strength by combining cement and mixed material. If it is contained in an amount of less than 0.2 part by weight, there may be a problem of inhibiting particle dispersion and lowering the strength after completion of the material, and when it is contained in an amount exceeding 1 part by weight, There may be a problem of inhibiting the chemical reaction.

상기 시멘트로는 이 분야에 공지된 시멘트가 제한 없이 사용될 수 있다. 예를 들어, 가장 일반적으로 사용되고 있는 포틀랜드 시멘트가 사용될 수 있다. As the cement, cement known in this field can be used without limitation. For example, the most commonly used Portland cement can be used.

본 발명의 경화용 조성물은 토사, 산업폐기물, 해사, 및 사막모래로 이루어진 군으로부터 선택되는 1종 이상의 경화에 사용될 수 있으나, 이에 한정되는 것은 아니다. The curing composition of the present invention can be used for at least one kind of curing selected from the group consisting of soil, industrial waste, marine, and desert sand, but is not limited thereto.
