碩士 === 元智大學 === 化學工程與材料科學學系 === 106 === This study is divided into three main parts. The first part provides the research background and objectives. The second part introduces the methodology, experimental design, and comparative analysis of experimental data and market research data. The third part summarizes the main results, answers the research questions, and then discusses and concludes them. In the first part of this study, it took the Energy Dispersive Spectroscopy (EDS) analysis results of the commercial insulation coatings to find out the ratio of calcium carbonate mixture, and use its asserted performance data to set this experiment goal. The second part of this study, it describes about the main experiment - Recipe modification of the new improved insulation coatings, and its Insulation capacity, Weatherability test and the cost analysis. Firstly, this study made use of the method of adding porous materials - Vermiculite to the material formula of the commercial insulation coatings to produce this improved insulation coatings with new formula. The experiment explores the change of the formula ratio of the insulation coatings which is adding Vermiculites, and it can easily adjust the apparent density of the insulation coatings. The decreased apparent density results in an increase of the porosity of the insulation coatings, and facilitates the insulation coatings to improve the heat insulating effect. The insulation effect of this improved insulation coatings with adding 1 wt% vermiculite has been approaching the commercial insulation coatings. And this improved insulation coatings can block the heat source 4 ℃ while it is under the constant temperature 42.5 ℃ heating plate. Secondly, it took the Weatherability test to study how the stability of both the commercial insulation coatings and this improved insulation coatings staying in Taiwan which is the high humidity and high sun exposure environment. The observation of the record in the appearance of size changes shows that this improved insulation coatings can welly adhere on two different outdoor building surface materials. Thirdly, it discusses the cost analysis. After market research it found that the cost of this improved insulation coatings is only 8% of the price of the commercial insulation coatings. The third part summarizes the main results, and to know that this improved insulation coatings is competitive in the market.
