The invention relates to the technical field of anti-fog rearview mirrors, in particular to an anti-scraping and anti-fog automobile rearview mirror and a preparation method thereof. The method comprises the following steps: step 1, putting a rearview mirror basic lens into a piranha solution, soaking for 8-12 hours at room temperature, washing with deionized water, and blow-drying with nitrogen; obtaining a preprocessed lens body; step 2, sequentially adding acidic silica sol, pyrrolidone siloxane and sodium pyrrolidone sulfonate into deionized water, and stirring and homogenizing at room temperature; adding hydrochloric acid and uniformly stirring; sequentially adding water-based polyacrylic resin and tetraethyl silicate, heating to 50-60 DEG C, and stirring for 10-12 hours, so as to obtain an anti-scraping and anti-fogging liquid; step 3, uniformly spraying an anti-scraping and anti-fog liquid on the surface of the pretreated mirror body, and curing at room temperature for 24 hours to form an anti-fog composite coating; the anti-scraping and anti-fog automobile rearview mirror is obtained.
本发明涉及防雾后视镜技术领域,具体为一种抗刮擦、防雾汽车后视镜及其制备方法。步骤1:将后视镜基础镜片置于食人鱼溶液中,室温浸泡8~12小时,去离子水冲洗,氮气吹干;得到预处理镜体;步骤2:将酸性硅溶胶、吡咯烷酮基硅氧烷、吡咯烷酮基磺酸钠依次加入去离子水中,室温下搅拌均质化;加入盐酸搅拌均匀;依次加入水性聚丙烯酸树脂、硅酸四乙酯,升温至50~60℃搅拌10~12小时,得到抗刮擦防雾液;步骤3:将抗刮擦防雾液均匀喷涂在预处理镜体表面,室温固化24小时,形成防雾复合涂层;得到抗刮擦、防雾汽车后视镜。
