Summary

Acetylated wood-silicate (AWS) composites and propionylated wood-silicate (PWS) composites were prepared and their dimensional stability and flame resistance evaluated. The results displayed that: (1) With the existing of silicate gels, the AWS and PWS composites showed lower values of bulking coefficient (B), antiswelling efficiency (ASE) during water and moisture absorptions, and moisture excluding efficiency (MEE) than the corresponding acetylated wood and propionylated woods, but the AWS and PWS composites still exhibited a fairly good dimensional stability. (2) The oxygen indexes (OIs) of the AWS and PWS composites were higher than those of untreated wood specimens, and increased with an increase in weight percent gain (WPGs) of silicate gel, endowing them with flame-resistance.
