摘要
[目的]硅系无机涂料的耐水性较差,固化过程中易发生起皮、开裂,使用后出现干擦掉粉现象,以及使用寿命短的问题亟需解决.[方法]以硅酸钾、硅溶胶和丙烯酸乳液为主要成膜物,结合钛白粉和石墨烯作为颜填料,再辅以适当的助剂,制得硅系无机防腐涂料.讨论了高模数硅酸钾溶液的稳定性,助剂的选择,以及成膜物、颜填料的用量对涂料性能的影响.[结果]该涂料不含游离甲醛,不含汞、镉等重金属,VOC(挥发性有机物)含量低,且具有优异的贮存稳定性、防腐性、阻燃性、耐水性、耐碱性、耐冲击性等性能.[结论]该涂料克服了传统无机硅酸盐涂料存在的缺点,满足建筑内外墙涂料相关标准的要求.
Abstract
[Introduction]The problems of current silicon-based inorganic paint such as poor water resistance,occurrence of peeling and cracking usually during curing,poor resistance to dry scrubbing after application,and short service life are urgently to be solved.[Method]A silicon-based inorganic anticorrosion paint was prepared with potassium silicate,silica sol,and acrylic emulsion as the main film-forming materials in combination with titania and graphene as fillers and some suitable auxiliary agents.The stability of high-modulus potassium silicate solution,the selection of auxiliary agents,and the effects of the amounts of film-forming materials and pigment/fillers on the properties of the paint were discussed.[Result]The paint does not contain free formaldehyde,mercury,cadmium,and other heavy metals with low VOC(volatile organic compound)content and has excellent storage stability,corrosion resistance,flame retardancy,water resistance,alkali resistance,impact resistance,etc.[Conclusion]It resolves the shortcomings of traditional inorganic silicate paint,and meets the relevant standards of interior and exterior wall paints for buildings.
