防火塗料塗布於建材表面，能防止底材直接接觸高溫，使得建築物結構不受重大損害，進而延長火場逃生時間，近年來由於環保意識高漲，開發水性無機防火塗料已成產業趨勢，本研究將不同重量百分比之氣凝膠添加於水性無機富鋅塗料中，期望能提升塗料性能。本研究實驗分為一般性能、熱性能以及耐候性能，一般性能包括塗料黏度、微結構分析以及粒徑分析，熱性能包括熱傳導率測量，和加熱後的微結構以及傅立葉光譜分析，並用TMA以及TGA探討塗料受熱過程中的體積和重量變化，高溫爐耐熱測試和圓錐量熱儀測試則用來檢測塗料保護基材及防火的能力。
研究結果顯示，添加氣凝膠會增加黏度和施工難度，但不影響塗層成膜性，並降低塗層的熱傳導率。在熱性能實驗中將塗料加熱後，證實本實驗室製造之氣凝膠具有出色的耐熱性，即使在高溫下也可以發揮隔熱作用。在熱機械分析中，含1%氣凝膠之塗料具有最小的體積變化，表示具有最佳的熱穩定性，熱重分析時，由於鋅在空氣中氧化，使得三種配方的塗料重量皆增加，但熔點都相同。800℃的耐熱實驗中，發現塗層剝落的比例會隨塗膜厚度增加而增加，且在一定的膜厚範圍內，噴塗方法的耐熱性比刷塗優秀，而添加氣凝膠之塗料比未添加的優秀。圓錐量熱儀的測試中，三種配方的塗料皆展現優秀的耐燃性。在耐候性測試中，添加氣凝膠之塗料幾乎看不出顏色變化。經過以上實驗，證明添加氣凝膠使許多性能更加出色，且添加重量比1%的氣凝膠比添加0%和2%更合適。

Applying fire-retardant coatings to building materials can prevent the substrate from directly coming into contact with high temperatures and can increase the time available to flee from the fire. In recent years, due to an increase in awareness related to protecting the environment, the development of water-based inorganic fire-retardant coatings has become a necessary trend. In this work, 0%, 1%, and 2% aerogel by weight are added to water-based inorganic zinc-rich coatings and then tested to evaluate performance. It was proven that adding aerogel improves performances, where the addition of 1% aerogel by weight was found to be more suitable than 0% and 2%.
The results showed that although adding aerogel increased the viscosity and difficulty of construction, it did not affect the formation of the coating film. On the other hand, the thermal conductivity was reduced. SEM images showed the excellent heat resistance of the proposed aerogel and indicated that it can exert heat insulation even at high temperatures. The thermal mechanical analysis suggested that the coating containing 1% aerogel had the best thermal stability. In the heat resistance test, it was found that the degree to which the coating peeling off increased with increases in the film thickness, and, within a certain thickness range, spraying was found to be better than brushing. The coating adding 1% aerogel offered the best protection in the tests of performance. In the test of the cone calorimeter, the coatings of the three formulations all showed excellent flame resistance. Moreover, their weather resistances were also very good.
