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 1 53.69°)with base course coating solvent content at 40 wt%,surface course coating resin content at 40 wt%,and namame-ter 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 1 50 ℃.Besides,the metal adhesion and anti-adhe-sion property were superior to nano-composite single-deck coating.It could reach the use standard of large chemical equipment.
