摘　　要：采用水性硅溶胶与硅丙树脂复配制备了水性硅溶胶-硅丙树脂复合金属防腐涂料。以Q235钢板为基材,研究了不同硅溶胶用量下涂层的力学性能、防腐性能及耐久性能,考察了喷砂与打磨两种不同的基材表面处理工艺对防腐涂料性能的影响。试验结果表明:硅溶胶改性后,复合涂层的耐盐雾时间长达3 000 h以上,氙灯照射250 h后,涂层不粉化、不脱落,附着力达0级,耐冲击性为50 cm,综合性能优异。Aqueous silica sol-silicone-acrylic resin composite metal anticorrosive coatings were prepared using water-based silica sol and silicone-acrylic resin. The mechanical properties, anti-corrosion performance and durability of the coating with different silica sol dosages were studied by using Q235 steel plate as the substrate. The effects of different surface treatment processes of sandblasting and polishing on the performance of anticorrosive coatings were investigated. The test results showed that the salt spray resistance of the composite coating are longer than 3 000 h after the modification of silica sol. After the coating were irradiated for 250 h under the Xenon lamp, it did not appear to be powdered or peeled off. Adhesive force of the coating reached grade 0 and impact resistance was 50 cm. The comprehensive performance of the coating was excellent.
