SUPERHYDROPHOBIC COATING AND PREPARATION METHODS THEREFOR AND APPLICATION THEREOF, SUPERHYDROPHOBIC FOAM CONCRETE AND PREPARATION METHODS THEREOF
To provide coating and foam concrete excellent in superhydrophobic performance as well as a preparing method thereof.SOLUTION: There is provided a superhydrophobic coating which contains an organosilane, an inorganic nanomaterial, and an emulsifying agent. A mass proportion of the components is controlled, so that the superhydrophobic coating can form a micro-nano mixed microstructure inside foam concrete. The organosilane forms dense hydrophobic surface layers on the surface and in inner pores of the foam concrete, and the nanomaterial forms uniformly distributed nano-bulges on the hydrophobic surface layers formed by the silane. The superhydrophobic performance of the foam concrete can be effectively improved by combining the two microstructures. A static contact angle of a surface of foam concrete prepared by the superhydrophobic coating is between 158° and 175°; a sliding angle thereof is between 5° and 10°; and water absorption thereof is less than 6%. Thus, the foam concrete exhibits excellent superhydrophobic performance.SELECTED DRAWING: None
【課題】超疎水性能に優れるコーティング及び発泡コンクリート並びにこれらの調製方法を提供する。【解決手段】超疎水性コーティングは、有機シラン及び無機ナノ材料、乳化剤が添加され、各成分の質量比を制御することにより、発泡コンクリートの内部でマイクロナノ混合微細構造を形成し、有機シランが発泡コンクリートの表面及び内部気孔に緻密な疎水表面層を形成し、シランで形成された疎水層の表面にナノ材料が均一に分布するナノ突起を形成し、この２種類の微細構造の組み合わせにより発泡コンクリートの超疎水性が効果的に向上する。超疎水性コーティングにより調製された発泡コンクリートの表面は、静的接触角が１５８°〜１７５°、回転角が５°〜１０°、吸水率が６％未満となり、超疎水性能に非常に優れる。【選択図】なし
