Durable concrete-based anti-corrosion and anti-fouling material and preparation method thereof
The invention relates to a durable concrete-based anti-corrosion and anti-fouling material and a preparation method thereof.The preparation method comprises the following specific steps that firstly, a plasma technology is used for etching the surface of concrete, the binding force of a coating and the concrete is improved, then epoxy asphalt is used for coating the surface of the concrete, drying is conducted, and the concrete has a waterproof function; then carrying out plasma treatment on the surface; and finally, coating the surface of the concrete base material with a mixture of the methacrylate block copolymer, the nano titanium dioxide and the graphene, and drying. The cured coating has low surface energy, marine organisms are difficult to attach to the surface of the coating, and the coating easily falls off under the action of water flow or other external forces even if the marine organisms are not firmly attached to the surface of the coating. Nanoscale titanium dioxide can greatly improve the performance of the coating, titanium dioxide has very strong oxidation ability under illumination conditions, can decompose a lot of organic pollutants, and can destroy the tissues of marine organisms to achieve the purpose of preventing and removing marine organisms. The antifouling paint can be applied to long-acting antifouling of marine facilities such as ship bottoms, offshore platforms, navigation marks, hydraulic steel gates and the like, and is used for preventing marine organism fouling.
本发明涉及一种耐久型混凝土基防腐防污材料及制备方法，其制备方法，具体步骤如下：先用等离子技术对混凝土表面进行刻蚀，提高涂层与混凝土的结合力，再用环氧沥青在混凝土表面涂层并干燥，使混凝土具有防水功能，然后再对表面进行等离子处理，最后将甲基丙烯酸酯嵌段共聚物和纳米二氧化钛、石墨烯混合物涂覆在混凝土基材表面并干燥。固化后的涂层具有低表面能，海洋生物难以在其表面附着，即使附着也不牢固，在水流或其他外力作用下很容易脱落。纳米级二氧化钛可以大大改善涂料的性能，由于二氧化钛在光照条件下具有很强的氧化能力，可以将许多的有机污染物进行分解，对于海生物，则可以破坏其组织，达到防除海生物的目的，可以应用于船舶船底、海上平台、航标、水工钢闸门等海洋设施的长效防污，用于防止海洋生物污损。
