Abstract

In this study, it was reviewed that the effect of solid capsules on the quality of surface repair materials and the healing properties of long-term aging, as part of a study to utilize self-healing surface repair materials using solid capsules as repair materials. As a result of evaluation of the rheological properties of self-healing surface repair materials according to the mixing of solid capsules, plastic viscosity, yield stress, and table flow tended to decrease. In the case of compressive strength, 1MPa per 1% of the solid capsule decreased proportionally. As a result of evaluating the long-term healing properties, when 10% of solid capsules were mixed, a healing rate of 90% was shown at 28 days of healing, because the solid capsule was preserved even after 91 days of age had elapsed. after 91 days of healing, even in the case of 5% of solid capsules, a healing rate of 90% was shown.

본 연구에서는 고상캡슐을 활용한 자기치유 표면보호재를 보수재료로 활용하기 위한 일환의 연구로써 고상캡슐이 표면보호재의 품질에 미치는 영향 및 장기재령의 치유 특성을 검토하였다. 고상캡슐 혼합에 따른 자기치유 표면보호재의 유변학적 특성 평가결과, 소성점도 및 항복응력, 테이블 플로우는 감소하는 경향이 나타났으며, 압축강도의 경우 고상캡슐 1%당 1 MPa이 비례적으로 감소하였다. 장기재령 치유특성을 평가한 결과, 재령 91일이 경과된 경우에도 고상캡슐이 보존되어 10% 혼합한 경우 치유재령 28일에 90% 수준의 치유율이 나타났으며, 치유재령 91일 경과후에는 고상캡슐 5%의 경우에도 90% 수준의 치유율이 나타났다.
