| Abstract: | The optimal conditions for preparing a nano-composite modified water-based epoxy coating were ascertained by orthogonal test and single factor experiment with the impact strength as index. The coating was characterized by infrared spectroscopy and thermal analysis. Results showed that the prepared nanocomposite-modified waterborne epoxy coating has good comprehensive properties when the dosage of curing agent 1,2–ethylenediamine is 10%,methacrylic acid(MAA) 4%,benzoyl peroxide(BPO) 2%,reaction temperature 50 °C and time 40 min,and the dosages of SiO2 and TiO2 are 4% and 2%,respectively. The coating has good thermal stability as well as water,acid and alkali resistance. Its tensile strength is 9.17 MPa,impact strength 40 kg·cm and adhesion strength 0 grade. |
