【摘要】：提出一套水工混凝土双层表面防护保温涂层材料系统,通过试验研究,验证了该系统面层涂料选用自主研发的CW620系列聚脲涂层,能与底层涂料较好地粘合,且其保温性能、耐候性和防渗抗裂能力良好,外表美观;底层材料选用聚苯乙烯、珍珠岩与环氧胶泥复掺,与混凝土粘结性能好,且具有较好的保温性能,还可填平混凝土表面凹凸不平的基面,形成相对平整的工作界面;此双层保温涂层材料系统可与水工混凝土形成一个整体,对水工建筑物起到有效的防护保温作用。
[Abstract]:A set of thermal insulation coating material system for double layer surface protection of hydraulic concrete is put forward. Through the experimental research, it is verified that the surface coating of this system selects CW620 series polyurea coating, which is developed independently, and can be bonded with the base coating well, and its thermal insulation performance is also verified. Good weather resistance, anti-seepage and crack resistance, beautiful appearance; Polystyrene is used as the bottom material, perlite and epoxy cement are mixed with each other, which has good bonding property with concrete, and has better thermal insulation property. It can also fill out the uneven base surface of concrete surface and form a relatively flat working interface. This double-layer thermal insulation coating material system can form a whole with hydraulic concrete and play an effective role in protection and insulation of hydraulic structures.
