The invention relates to a preparation method of a photovoltaic wear-resistant flame-retardant self-cleaning antireflection coating, which comprises the following steps: preparing an AlOOH nanosheet and an Al2O3 nanosheet, further preparing a reticular SiO2 sol loaded with the Al2O3 nanosheet and the AlOOH nanosheet, and obtaining a reticular SiO2 coating. The preparation method has the beneficial effects that the Al2O3 nanosheets are added, so that the balance between anti-reflection performance and wear resistance can be achieved, the AlOOH nanosheets are added, the hydrophobic performance of a film layer can be improved, and SiO2 is prepared into a net-shaped structure, so that the light transmission performance of the coating can be further ensured. 本发明涉及一种用于光伏的耐磨阻燃自清洁减反射涂层制备方法，包括：制备AlOOH纳米片和Al2O3纳米片，进一步制备负载有Al2O3纳米片和AlOOH纳米片的网状SiO2溶胶，并获取网状SiO2涂层。本发明的有益效果是：本发明添加了Al2O3纳米片能做到减反性能和耐磨性能之间的平衡，并添加了AlOOH纳米片，可以使得膜层的疏水性能得到改善，并将SiO2制备成网状结构，可以进一步保证涂层透光性能。
