    • The invention at its most basic is a process for improving the dimensional stability of wood by reducing the fluctuation in the wood fibers caused by changes in moisture content. This is accomplished by carrying a reactive silicone polymer into the wood to contact the internal micro pore structure of the wood, and altering the properties of the wood fiber so that less change in volume occurs with changes in moisture content. The invention may be viewed as a method of treatment useful for improving the properties of wood for use as a construction material that comprises contacting wood with at least one component selected from the group consisting of : (1) an aliphatic solvent composed primarily of C 7 - C 16 straight chain aliphatic, cycloparaffinic and isoparaffinic hydrocarbons, that contains less than 0.5% aromatics; (2) a natural product oil and further comprising at least one (3) silicone based polymer that forms a film in the presence of a catalyst and water comprising at least one component selected from the group consisting of (A) a copolymer of silicone units having the general formula: (M a D b T c Q d ) x where M is R 3 SiO 1 / 2 -; D is R 2 SiO-; T is RSiO 3 / 2 -; Q is Si(O 1/ / 2 ) 4 -; R is a generalized organic radical selected from: linear or branched hydrocarbon radicals of 1-8 carbons containing 0-1 degree of unsaturation, or phenyl, or trifluoropropyl radicals; a, b, c, d are real numbers and further provided the ratio of a/(c+d) is between 0 and 4; the ratio of b to the rest is not subject to limitation provided the final base viscosity is between 50-3500cSt; and at least one R group of each molecule must be a hydrolysable group; and (B) (M a D b T c Q d ) x formula the following parameters apply: the ratio of a/(c+d) is between 0 and 4; the ratio of b to the rest is not subject to limitation provided the final cross linker viscosity is below 350cSt; and R is a generalized organic radical selected from: linear or branched hydrocarbon radicals of 1-8 carbons containing 0-1 degree of unsaturation, or phenyl, or trifluoropropyl radicals and at least one R group of each molecule must be a hydrolysable group.
    • 本发明最基本的是通过减少由水分含量变化引起的木纤维的波动来提高木材的尺寸稳定性的方法。 这通过将反应性硅氧烷聚合物携带到木材中以接触木材的内部微孔结构并改变木纤维的性质来实现,使得随着水分含量的变化发生体积变化较小。 本发明可以被看作是可用于改善用作建筑材料的木材性能的处理方法,该建筑材料包括使木材与至少一种选自以下的组分接触:(1)主要由C < 含有少于0.5%芳族化合物的直链脂族,环烷烃和异链烷烃; (2)天然产物油,并且还包含至少一种(3)在催化剂存在下形成膜的硅氧烷基聚合物和水,所述水包含至少一种选自以下的组分:(A)硅氧烷单元的共聚物 具有以下通式:(M a,a,b,b,c)C x >其中M是R 3 SiO 2/2/2。 D是R 2 SiO-; T是RSiO 3/2/2。 Q是Si(O 1/2/2)4 - 。 R是选自以下的通式有机基团:含有0-1不饱和度的1-8个碳的直链或支链烃基,或苯基或三氟丙基; a,b,c,d是实数,进一步提供a /(c + d)的比率在0和4之间; b与其余的比例不受限制,条件是最终基础粘度在50-3500cSt之间; 并且每个分子的至少一个R基团必须是可水解基团; 和(B)(M)其中,(B)(C) 公式如下:a /(c + d)的比率在0和4之间; b与其余的比例不受限制,条件是最终交联剂粘度低于350cSt; 并且R是选自以下的广义有机基团:含有0-1不饱和度的1-8个碳原子的直链或支链烃基,或苯基或三氟丙基和每个分子的至少一个R基团必须是可水解基团。
