Currently, as a floor finishing material for improving the environmental structure while reinforcing the concrete floor surface, a chemical method is mainly used, and most of the chemical resins use epoxy resins having excellent physical properties. Looking at the concrete surface construction method using such an epoxy resin there is a coating method, a lining method, a resin mortar method. Among these methods, the resin mortar method is required to be applied to many parts because it has excellent mechanical properties and can give a reflecting composition, but in the method of using a chemical resin such as the existing epoxy resin is essential in the manufacturing and use process Due to organic solvents, the harmful effects on the human body and the natural environment are becoming more serious, and an alternative to the problem is urgently required.
또한, 화학 수지를 이용한 방법에 있어서 유기 용제의 직접적인 노출로 인한 폐해가 문제시되면서 이를 해결하기 위한 노력의 하나로 수용성 제품을 이용한 공법들이 이용되고 있으나 이들 방법에 있어서도 수용성 조성에서 친수성기를 조절하기 위하여 사용되는 유기용제가 경화 성분의 가교성을 저해하는 요인으로 작용함으로 인하여 박막형태의 코팅용도로서만 이용될 뿐 고강도 기능을 요하는 바닥재 분야에서는 그 사용이 제한되어 왔다. In addition, in the method using chemical resins, problems caused by direct exposure of organic solvents are problematic, and methods using water-soluble products have been used as an effort to solve the problems. However, these methods are also used to control hydrophilic groups in water-soluble compositions. Since the organic solvent acts as a factor that inhibits the crosslinkability of the curing component, its use has been limited in the field of flooring, which is used only for coating in the form of a thin film and requires a high strength function.
한편, 본 발명자가 에폭시 수지를 이용한 수성 조성물로서 발표한 대한민국 특허 제0632089호 및 제0167858호에는 코팅형식의 표면 보수제 조성물 및 모르타르 형식의 바닥재 조성물이 제안되어 있으나, 제0167858호 바닥제의 경우 공극으로 인한 오염 문제 및 기계적 물성의 한계 등의 문제가 존재하여 실외 도보용으로만 그 용도가 제한되는 문제점이 있었다. 또한, 대한민국 특허 제0536471호는 에폭시 수지, 물, 희석제, 시멘트, 모래, 자갈 등을 작업현장에서 혼합하여 콘크리트 바닥면 훼손 부위의 부분 보수 시공에서 특정 경화제를 이용함으로써 통기성을 확보하여 성능을 보강하는 방법이 제안되었으나, 이 방법에서는 수지액을 혼합하여 시공할 때 시공 두께에 따라 수지액이 기공에 막을 형성하여 통기성 확보가 용이하지 않고, 또한 외부로부터 결화가 일어나 수지내에 함유된 비반응 희석제 및 물의 신속한 휘발 및 증발이 저해받는 문제점이 있었다.  Meanwhile, Korean Patent Nos. 0632089 and 0167858, which are disclosed by the present inventors as an aqueous composition using an epoxy resin, have proposed a surface-repairing agent composition in the form of a coating and a flooring composition in the form of a mortar. Problems such as contamination problems and limitations of mechanical properties exist, such that the use is limited only to outdoor walking. In addition, the Republic of Korea Patent No. 0538471, epoxy resin, water, thinner, cement, sand, gravel, etc. in the work site by using a specific curing agent in the partial repair work of damaged concrete floors to secure breathability to enhance performance Although the method has been proposed, in this method, when the resin solution is mixed and installed, the resin solution forms a membrane in the pores according to the thickness of the construction, so that breathability is not easily secured, and condensation occurs from the outside. There was a problem that rapid volatilization and evaporation are inhibited.
상기와 같은 문제점으로 인하여 현재까지 에폭시 수지를 이용한 바닥제 모르타르 시공에서 수성으로 조성한 것을 사용하는 것은 국내외에서 일반적인 방법이 아니었다. 또한, 기존의 에폭시 수지를 이용한 모르타르 조성물은 고강도 등의 기능적 우수성에도 불구하고 복잡한 시공절차와 높은 시공비용으로 인하여 활성화되지 못하고 있었는데, 본 발명자는 이러한 문제점을 해결하고자 대한민국 특허 제0145117호, 제0476728호, 제0252465호 및 대한민국 특허출원 제2007-115733호 등에서 이를 개선하는 방법을 제안한 바 있다. 그러나 이들 방법은 모두 비반응성 희석제로서 유기 용제를 사용하고 있으므로 환경 친화적인 관점 및 생산 원가의 면에서는 개선의 여지가 많았다.  Due to the problems described above, it is not a general method at home and abroad to use an aqueous composition of a floor mortar using epoxy resin. In addition, the conventional mortar composition using the epoxy resin was not activated due to complex construction procedures and high construction costs, despite functional excellence, such as high strength, the present inventors to solve these problems, Korean Patent No. 0145117, No. 0476728 , Korean Patent No. 0252465 and Korean Patent Application No. 2007-115733 have proposed a method for improving this. However, since all of these methods use organic solvents as non-reactive diluents, there is much room for improvement in terms of environmentally friendly aspects and production costs.
본 발명자는 상기 문제를 해결하기 위하여 부단히 연구 노력한 결과, 에폭시 수지에 응집제를 분산 및 내재시킨 후 유기 용제를 전혀 사용하지 않은 상태에서 물과 유화제만을 사용하여 팽윤시키는 방법에 의하여 안정적으로 적정의 부동성을 형성시킬 수 있음을 발견하여 본 발명을 완성하였다.       The present inventors have steadily researched in order to solve the above problems, and as a result of dispersing and embedding a flocculant in an epoxy resin and then swelling using only water and an emulsifier without using an organic solvent at all, stably, The present invention has been completed by discovering that it can be formed.
본 발명은 에폭시 수지 조성물을 이용하여 콘크리트 표면을 시공함에 있어 단축된 공정으로 시공을 완료할 수 있어 작업성이 크게 개선되며, 강도 등 기계적 물성을 종래 방법 수준 이상으로 유지시킬 수 있을 뿐만 아니라 콘크리트 표면을 유지 및 보수하는 비용 및 시간을 크게 줄일 수 있어 생산성을 획기적으로 향상시킬 수 있는 동시에 유기 화합물인 비반응 희석제를 전혀 사용하지 않아 환경 친화적인 수성 에폭시 수지 모르타르 조성물, 이를 포함하는 수성 접착제 및 수성 코팅제를 제공하는 것을 목적으로 한다. The present invention can be completed in a shortened process in the construction of the concrete surface using the epoxy resin composition can greatly improve the workability, not only can maintain the mechanical properties such as strength above the conventional method level, but also the concrete surface It is possible to greatly reduce the cost and time of maintenance and repair, which can greatly improve productivity and at the same time use environmentally friendly non-reactive diluent, which is an environmentally friendly aqueous epoxy resin mortar composition, aqueous adhesive and aqueous coating agent comprising the same. The purpose is to provide.
