摘要
Abstract
The surface modification of shellac was carried out using the titanate coupling agent NDZ102,and the modified shellac(MSP)was filled into the FEVE coating to prepare the MSP/acrylic/FEVE composite coating.Fourier transform infrared spectroscopy(FTIR),contact angle meter and scanning electron microscope(SEM)were used to characterize the shellac before and after modification,and the abrasion and anti-corrosion properties of the coatings were analyzed by low-temperature friction and wear testing machine and electrochemical impedance spectroscopy(EIS).The results showed that the surface modification of shellac by NDZ102 can be realized by using anhydrous ethanol as the dispersant,NDZ102 mass fraction of 3％,reaction temperature of 90 ℃ and reaction time of 30 min.The wear rate of the MSP/acrylic/FEVE composite coating was 13.2％when the amount of MSP added was 10％,which was enhanced by 30.41％relative to that of the pure FEVE coating;and the |Z|0.01Hz of the coating was 3.89×107Ω·cm2 after immersing in 3.5％NaCl solution for 20 days,which was enhanced by two orders of magnitude compared with that of the pure FEVE coating.This indicates that the addition of a certain amount of MSP can enhance the corrosion and friction resistance of the coating.关键词
