| Résumé : |
Phosphorus-containing liquid epoxidate polybutadiene (PDCP-LEPB) is synthesized and used as a reactive additive to improve the water, wear and fire resistance of UV-curable acrylate coatings containing nano-SiO2 as a filler. The structure of PDCP-LEPB and the curing condition are confirmed by Fourier transform infrared spectroscopy (FTIR). The addition of PDCP-LEPB should be controlled at around 10% as shown by thermal stability measurements; with the addition of PDCP-LEPB, composites show earlier degradation to release flame-retardant components, and thus the fire resistance of plywood is improved when its surface is applied by the composite coatings containing PDCP-LEPB. Besides, the fire protecting ability can be greatly enhanced with SiO2 addition due to the synergistic effect of P, Si and Cl coexistence in the matrix. The addition of PDCP-LEPB improves the water resistance of plywood as reflected by the water absorption rates, contact angle measurements and stain resistance test due to the hydrophobic nature of olefin backbone and increment of crosslinking density; the addition of nano-SiO2 has a much more positive effect on the improvement in their stain resistance and wear resistance due to the increase in surface roughness and stiffness, respectively. |
