| Résumé : |
Self-matting acrylate has attracted much interest due to excellent weather resistance, hardness, water resistance, and chemical resistance. However, the poor mechanical properties of acrylate limit its application in coatings. To overcome this problem, a series of self-matting acrylate emulsions (SMAE) modified by xylitol-based hyperbranched urethane acrylate (HP-IH) were successfully synthesized. The results revealed that the amount of emulsifier was the primary factor affecting the gloss of the films. Upon the incorporation of HP-IH, the elongation at break and fracture energy of the SMAE films were significantly improved by 52.6% and 59.6%, respectively, due to the internal plastic effect and increased crosslink density induced by HP-IH. The S-2-1.5 sample exhibited the excellent comprehensive performance, i.e., tensile strength of 12.7 MPa, elongation at break of 952%, fracture energy of 71.1 MJ/m3, adhesion of 5B, temperature of 5% weight loss at 350 °C, and gloss at 60° of 14.8, respectively, indicating its great application potential in the field of low-gloss coatings. |
