Epoxy resins, novolac epoxy resins and plastic epoxy resins.
상기의 에폭시 수지들을 주제로 사용하는 종래의 에폭시 도료는 내약품성, 부착성 및 기계적 특성 등이 우수한 반면, 에폭시 수지의 분산에 사용되는 유기 용제로 인하여 작업성이 저하되고, 화재에 대한 위험성도 클 뿐만 아니라 환경오염을 일으키는 등의 문제점이 있었다.Conventional epoxy paints using the above epoxy resins have excellent chemical resistance, adhesiveness and mechanical properties, while the workability is lowered due to the organic solvents used to disperse the epoxy resins, and the risk of fire is greater. In addition, there were problems such as causing environmental pollution.
이를 개선하기 위해 유기용제형 에폭시 도료 이상의 성능을 발휘할 수 있는 수성 도료에 관한 연구가 활발히 진행되고 있는 바, 수용성 에폭시 도료는 유기 용제를 사용하지 않으므로 좁은 공간, 건축물의 실내 또는 지하실 물탱크 내부 등과 같은 환기가 잘 되지 않는 곳에서의 작업이 용이할 뿐만 아니라 화제나 폭발의 위험이 없으며, 유해 유기 용제의 배출이 없다는 점에서 매우 환경 친화력이 있는 도료로서 최근 그 사용이 증대되고 있다.In order to improve this problem, active researches have been conducted on water-based paints that can perform more than organic solvent-type epoxy paints. Since water-soluble epoxy paints do not use organic solvents, such as a narrow space, a building interior, or a basement water tank, etc. It is easy to work in poorly ventilated places, and there is no danger of fire or explosion, and there is no discharge of harmful organic solvents. Therefore, its use has recently increased.
그러나, 수용성 에폭시 도료는 유기용제형 에폭시 도료에 비하여 콘크리트 구조물과의 부착력이 떨어지고, 내구성과 저장안정성이 좋지 않으며, 특히 상수도 시설물에 사용될 경우 방식성이 나쁘고 유체의 흐름에 대한 저항성이 좋지 않기 때문에 도장 표면이 박리되는 등 많은 문제점을 갖고 있다.However, water-soluble epoxy paints have lower adhesion to concrete structures, poor durability and storage stability than organic solvent-type epoxy paints, and especially when used in water supply facilities, they have poor corrosion resistance and poor resistance to fluid flow. There are many problems such as the surface peeling off.

Table 1 shows.
그리고, 용출시험을 실시하여 탁도, 색도, 과망간산 소비량, 잔류염소의 감량, 시안 화합물, 페놀 화합물 및 아민 화합물의 검출유무와 냄새 및 맛을 측정하여 그 결과를 다음 표 1에 나타내었다.The dissolution test was carried out to measure turbidity, color, permanganic acid consumption, loss of residual chlorine, the presence or absence of cyan compounds, phenol compounds and amine compounds, odor and taste, and the results are shown in Table 1 below.
이때, 고착건조시간 및 가사시간의 측정은 KSM 5000 측정방법에 의거하여 측정하였고, 내굴곡성, 내충격성, 내알카리성, 내산성, 염수분무시험 및 냉열반복시험은 KSM 5307 방법에 따라 측정하였다. 그리고, 접착강도는 KSM 3734 방법에 의거하여 측정하였고, 내마모성 시험은 수조 내에서 수용성 에폭시 도료를 코팅하고 물을 유속 1.0 m/sec로 흘려보내면서 60일 동안 측정하여 박리된 도료의 양을 측정하였다.At this time, the fixation drying time and the pot life were measured according to the KSM 5000 measurement method, and the bending resistance, impact resistance, alkali resistance, acid resistance, salt spray test and cold heat repetition test were measured according to the KSM 5307 method. In addition, the adhesive strength was measured according to the KSM 3734 method, and the abrasion resistance test was performed for 60 days while coating the water-soluble epoxy paint in a water bath and flowing water at a flow rate of 1.0 m / sec to measure the amount of the peeled paint. .
또한, 탁도, 색도, 과망간산 소비량, 잔류 염소의 감량, 시안 화합물, 페놀 화합물 및 아민 화합물의 검출유무, 그리고 냄새 및 맛을 측정하는 용출시험은 KSD 8502호에 의거하여 측정하였다.In addition, the elution test for measuring turbidity, color, permanganic acid consumption, loss of residual chlorine, cyan compounds, phenol compounds and amine compounds, and smell and taste were measured according to KSD 8502.

또한, 종래 수용성 에폭시 도료에서의 취약물성인 접착강도에서는 종래 10kgf/㎠에서 19.3kgf/㎠로 93%나 증가됨을 알 수 있는 바, 이는 본 발명에 따른 도료 조성물이 상수도 시설물에 도장되더라도 표면박리에 의한 하자를 방지할 수 있음을 보여준다.In addition, it can be seen that the adhesive strength, which is weak in conventional water-soluble epoxy paints, is increased by 93% from 10 kgf / cm 2 to 19.3kgf / cm 2, even though the coating composition according to the present invention is coated on water supply facilities. It shows that the defect can be prevented.
그리고, 흐르는 물에서 측정한 내마모성 시험 결과 종래의 수용성 에폭시 도료에 비하여 5배 정도 내마모성이 향상되었음을 알 수 있다.And, as a result of the abrasion resistance test measured in running water, it can be seen that the abrasion resistance is improved by about five times compared to the conventional water-soluble epoxy paint.
