Anti-aging super-hydrophobic composite coating for road
The invention relates to an anti-aging super-hydrophobic composite coating for roads, and belongs to the technical field of super-hydrophobic coatings. The problems that an existing super-hydrophobic coating is prone to aging under ultraviolet illumination, not firm in bonding with a base body at low temperature, prone to abrasion and falling off under the repeated action of driving loads and the like are mainly solved. The anti-aging super-hydrophobic composite coating is mainly composed of a hydrophobic layer, a bonding layer and a base body, the bonding layer composed of waterborne polyurethane, oily polyurethane and fibers is sprayed on an asphalt pavement, then a powdery super-hydrophobic material prepared from modified rutile type nanometer titanium dioxide and stearic acid is sprayed on the bonding layer, and finally the anti-aging super-hydrophobic composite coating is obtained after curing. The key innovation point of the invention is that the bonding layer simultaneously has the characteristics of water resistance, low temperature resistance and the like of two kinds of polyurethane, and the super-hydrophobic composite coating is made of modified rutile type nano titanium dioxide with extremely strong light catalytic activity, so that the ageing resistance and wear resistance of the super-hydrophobic material are enhanced.
本发明是一种路用耐老化超疏水复合涂层，属于超疏水涂层技术领域。主要解决现有超疏水涂层在紫外线光照下易老化，低温下与基体粘结情况不牢，在行车荷载的反复作用下易磨损脱落等问题。本发明主要由疏水层、粘结层和基体组成，在沥青路面上喷涂由水性聚氨酯、油性聚氨酯、纤维组成的粘结层，再在粘结层上喷涂由改性金红石型纳米二氧化钛、硬脂酸制成的粉末状超疏水材料，最终固化后得到耐老化超疏水复合涂层。本发明的关键创新点在于粘结层同时具有两种聚氨酯防水、耐低温等特点，超疏水复合涂层使用有极强光催化活性的改性金红石型纳米二氧化钛制成，增强了超疏水材料的抗老化性和耐磨性。
