Acrylate resin is a common material in relic protection,but the cost of pure acrylate resin isrelatively higher. The vinyl acetate(VAc)had the lower price and the better weather resistance,so the F-Si-vinylacetate-acrylate copolymers containing different nano-SiO_2 contents were prepared when the part VAc wasused as replacing MMA(methyl methacrylate),and the nano-SiO_2 and TFEMA(trifluoroethyl methacrylate)wereintroduced into system. The research results showed that the F-Si-vinyl acetate-acrylate copolymer...
