Abstract
In order to solve weakness, undesirable abrasion resistance, and hardness of a water-based wood coating film, modified surface nano-alumina was made in the water-based wood coating. The effect of surfactant type and amount on the performance of nano-alumina slurry was investigated. How the performance of the polyacrylate wood coating was affected by the size, amount, and mixing method of nano slurry was studied, as well as the characterization of nano-alumina slurry and modified polyacrylate wood coating. The results showed that, by compounding the non-ionic surfactant polyoxyethylene octylphenol ether (OPEO) and anionic surfactant sodium polyacrylate of surface modification of nano-alumina, the nano-alumina slurry had excellent performance and good stability when the amount of nano-alumina was 0.6 wt% and 3.2 wt%, respectively. When 1.5 wt% of nano slurry was mixed with the water-based polyacrylate emulsion to a hybrid during the pre-emulsification phase, the wood coating film had high performance, and good abrasion resistance and hardness.
