Gradient composite protective coating for hydraulic concrete and preparation method thereof
The invention provides a gradient composite protective coating for hydraulic concrete and a preparation method of the gradient composite protective coating, and relates to the technical field of protective coatings. The gradient composite protective coating for the hydraulic concrete comprises an isolating layer and a protective layer, the isolating layer is a YEP (Yttrium Ethylene Propylene) toughened epoxy putty isolating layer; the protective layer is a high-performance elastic coating or a high-toughness coating. The base layer concrete, the isolation layer and the protection layer form a rigidity-toughness-elasticity/high-toughness performance gradient in the vertical normal direction of the base plane, and a performance gradient composite coating structure is formed. Wherein the tough isolating layer is used for isolating a water seepage channel of porous concrete, preventing the elastic coating from bulging and cracking, providing a good base surface condition for the elastic coating and blocking surface defects and air holes of the concrete; the elastic coating is used for providing all-around medium isolation protection for concrete and providing functional effects of surface roughness reduction, abrasion resistance and the like for water conveyance projects.
本发明提供了一种用于水工混凝土的梯度复合防护涂层及其制备方法，涉及防护涂层技术领域。所述用于水工混凝土的梯度复合防护涂层包括隔离层与防护层；所述隔离层为YEP增韧型环氧腻子隔离层；所述防护层为高性能弹性涂层或高韧性涂层。基层混凝土—隔离层—防护层在基面垂直法向上形成刚性—韧性—弹性/高韧性的性能梯度，构成性能梯度复合涂层结构。其中韧性隔离层的作用是隔离多孔性混凝土的渗水通道，防止弹性涂层起鼓、破裂，并为弹性涂层提供良好的基面条件，封堵混凝土表面缺陷与气孔；弹性涂层的作用是为混凝土提供全方位的介质隔离防护，并可为输水工程提供表面降糙、抗冲磨等功能性效果。
