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.
