摘要: 以环氧改性有机硅树脂作为涂层的底层材料、纳米SiO2-环氧改性有机硅树脂复合涂层作为面层材料,制备适用于大型化工设备的纳米复合双层防垢涂层.通过对涂层各层涂料主要成分配比进行分析,并分别对单、双层涂层的综合性能进行测试,结果表明:在底层溶剂含量为40 wt%,面层树脂含量为40 wt%,纳米SiO2含量为9.1 wt%时,所制备出的双层复合涂层,其疏水性能达到最佳状态(接触角为153.69°);双层涂层具有单层涂层良好的耐化学腐蚀性、理想的硬度(3H级)与150℃较低温固化等优点,而且其金属附着力和防粘污力明显优于纳米复合单层涂层,符合大型化工设备的使用标准.Abstract: Nano-composite bistratal antiscale coating for large chemical equipment was preparaed with epoxy modified organosilicone resin as base course material, with nano SiO2-epoxy modified organosilicone resin composite coating as surface course material. Through analyzing the ingredient ratio of each layer, and testing integrated performance of single-deck coating and double-deck coating by experiment, the results showed that hydrophobic of the bistratal composite coating could reach the best status (contact angle was 153.69°)with base course coating solvent content at 40 wt%, surface course coating resin content at 40 wt%, and namameter SiO2 content at 9.1 wt%. As single-deck coating, double-deck coating had good resistance to chemical corrosion, ideal hardness(3H) and could be solidified at 150℃. Besides, the metal adhesion and anti-adhesion property were superior to nano-composite single-deck coating. It could reach the use standard of large chemical equipment.
