A process for improving the dimensional stability and the mechanical properties of wood, in particular hardness, scratch resistance and gloss while substantially maintaining the wood material appearance combined with an easy processability with tools and industrial machines, characterized in that the wood is subjected to the following steps:
1) drying at 60 -80°C from 1 to 12 hours,
2) vacuum application,
3) wood impregnation with polymerizable monomers selected from C1-C8 alkyl (meth)acrylates, styrene/acrylonitrile, vinylacetate, silane monomers having formula (R1ZR2) ySi (OR3) x
and polymerization by using organic or inorganic redox catalysts, the polymerization temperature being comprised between -15 and 40°C, or between >40-80°C.
4) recovery of the wood containing the polymer.
一种改善木材尺寸稳定性和机械性能,特别是硬度、抗划伤性和光泽度,同时基本保持木质材料外观并易于使用工具和工业机械加工的工艺,其特征在于木材需经过以下步骤:
1) 在 60 -80°C 温度下干燥 1 - 12 小时、
2) 抽真空
3) 用可聚合的单体浸渍木材,这些单体选自 C1-C8 烷基(甲基)
丙烯酸酯、
苯乙烯/
丙烯腈、
乙酸乙烯酯、
硅烷单体,其式为 (R1ZR2) ySi (OR3) x。
并使用有机或无机氧化还原催化剂进行聚合,聚合温度在 -15-40°C 之间,或 >40-80°C 之间。
4) 回收含有聚合物的木材。
