제목 Synthesis and Characterization of Silica Xerogel coated Melamine Foam
초록 Melamine foam has been made from melamine-formaldehyde precondensate by using microwave. Melamine foam had open cell and over 90% of high porosity. The foam absorbs sound reducing noise significantly with its unique three dimensional reticular open cell structure. It could be particularly used for thermal insulation and sound absorption in the construction and the transportation industries. In this study, silica xerogel coated melamine foam has been made by ambient drying process of wet silica gel that was obtained by soaking and removing the polymeric silica sol derived from methyltrimethoxysilane/methanol/water via sol gel process. The microstructure and density of xerogel coated melamine foam could be controlled by adjusting the concentration of the sol and the aging condition. After coating with silica xerogel the hydrophobicity of melamine foam was much improved. The degree of hydrophobicity of xerogel coated melamine foams were in the range of 90~95%.
