Modification of Chinese Fir with Silica Sol/Acrylate Emulsion
A silica sol/acrylate emulsion was prepared to impregnate Chinese fir.Effects of impregnating pressure and duration on properties of the modified wood were evaluated.The results showed that silica sol/acrylate emulsion entered into the wood under pressure and was then cured and filled in the gaps of the wood.Compared with untreated wood,mechanical properties of the modified wood were increased due to new chemical bonding.The optimum modification parameters obtained were impregnating pressure of 1.0 MPa maintained for 90 minutes.
