碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 86 === This study discusses the fire resistance, mechanism of fire resist and durability of intumescent coating by small scale fire test, thermo-analysis, weatherometer test and salt spray test. From the results of tests, there are five conclusions that be made. These include the following. 1.In the same section scale factor, it is positive relationship between fire resistance time and dry film thickness, but it isn''t linear dependence. 2.The cohesion and adhesion of intumesced coating are important factors of fire resistance. 3.According to the mechanism of fire resist, the typical curve of time and temperature during the fire test can be separated four different steps. It includes non-intumesced step, intumescing step, stable step and unstable step. 4.According to the result of weatherometer test, it should be satisfied when the intumescent coating is used in internal. 5.According to the result of salt spray test, the boundary of coating is a weak boundary of durability.
