- 为提高建筑常用 Q345 钢板的抗污性能，采用磷化并结合喷涂工艺在 Q345 钢板表面构建超疏水膜层。首先通过调控磷化液温度在 Q345 钢板表面制备具有较为规则微米级结构的锌系磷化膜，然后均匀喷涂含 TiO 2 颗粒的树脂涂料，树脂固化成膜与锌系磷化膜紧密结合并将分散的疏水性 TiO 2 颗粒固定，从而构建超疏水膜层。结果表明：磷化液温度 60 ℃ 条件下成膜均匀并且形成规则致密的微米级结构，树脂固化成膜与锌系磷化膜紧密结合使得超疏水膜层具有良好的机械稳定性和化学稳定性。超疏水膜层的化学成分为 Zn 、 P 、 O 、 Ti 、 C 和 Si 元素，表面接触角达到 153.2 ° ，其表面能低并且形成微纳米复合结构，能有效抑制模拟污染物的聚集和黏附，表现出良好的抗污性能。
- Abstract:
- ： A superhydrophobic film was constructed on the surface of Q345 steel plate by phosphating combined with spraying process in order to improve the antifouling performance of Q345 steel plate. Firstly ， a zinc phosphating film with relatively regular micron structure was prepared on the surface of Q345 steel plate by adjusting the phosphating solution temperature. Then ， the resin coating containing TiO 2 particles was sprayed uniformly on the zinc phosphating film. The resin curing film was closely bonded with zinc phosphating film and the dispersed hydrophobic TiO 2 particles were fixed ， so as to construct superhydrophobic film. The results show that the film is uniform and the regular compact micron structure is formed under the condition of phosphating solution 60 ℃ ， and the resin curing film is closely bonded with zinc phosphating film which makes the superhydrophobic film have good mechanical and chemical stability. The chemical composition of the superhydrophobic film is Zn ， P ， O ， Ti ， C and Si elements ， and the surface contact angle reaches 153.2 °. The superhydrophobic film has low surface energy and micro-nano composite structure ， which can effectively inhibit the accumulation and adhesion of simulated pollutants ， showing good antifouling performance.
