Abstract：

The　SiO2/VAc-MMA-AA　core-shell　composite　latex　was　prepared　by　coating　silica　sol　with　polyvinyl　acetate-acylate　copolymer.　Then　the　core-shell　composite　emulsion　was　introduced　into　poplar　wood　materials　to　form　an　inorganic/organic　core-shell　composite　wood.　The　structure　of　the　core-shell　composite　latex　and　the　modified　wood　were　investigated　by　TEM　and　FT-IR.　TG　measurement　of　the　modified　wood　showed　that　the　temperature　of　thermal　degradation　of　the　modified　wood　was　higher　than　that　of　the　primal　wood.　The　limited　oxygen　index　of　the　modified　wood　with　45%　WPG　was　40.1%.　Compared　with　that　of　primal　poplar　wood,　the　mechanical　properties　of　composite　wood　were　greatly　improved.
