현장 도포 횟수와 재도장 시간 간격에 따른 합판의 방염성능 비교

Abstract

In the case of flame-retardant treatment using flame-retardant paint in the field, it is usually applied repeatedly three times. Therefore, this study was conducted to find out how much the difference between the number of coatings and the time interval of repainting affects the flame retardant performance and the pass rate according to each condition. In the experiment, a matte transparent water-based flame retardant paint and general plywood were used, and as a result, the more times the flame retardant paint was applied, the longer the repainting time interval, the better the flame retardant performance. At this time, the number of times of application was stably included in the flame retardant performance criterion from two or more times, and there was no significant difference in the numerical change of the flame retardant performance criterion from two or more times of application. On the other hand, the difference in flame retardant performance according to the difference in repainting time interval showed a relatively small difference. If this study is applied in the field, it is likely to be applied more than two times, and if it is dried for 1 hour, economic feasibility and efficiency can be considered. In this way, through this study, it was possible to compare the difference in flame retardant performance according to the difference in the number of coatings and time intervals for repainting, and it could be grafted to the field.
