硅氧烷的水性分散体降低木质基材的涨筋的应用以及含有防涨筋涂层的制品
摘要：
本发明涉及硅氧烷的水性分散体降低木质基材的涨筋的应用以及含有防涨筋涂层的制品。所述制品包含(a)木质基材，其具有至少一个主表面；(b)直接涂覆在所述木制基材的主表面上由硅氧烷的水性分散体形成的防涨筋涂层；和(c)涂覆在所述防涨筋涂层上的由水性涂料组合物形成的一个或多个涂层，其中，所述硅氧烷包含化学键合到所述硅氧烷的分子骨架上的一个或多个疏水性基团和一个或多个亲水性基团；并且其中，所述硅氧烷的粒径在5-100nm范围内。
摘要（英）：

The present disclosure relates to use of an aqueous dispersion of siloxane for reducing grain puffing of a wood substrate and an article comprising an antt grain puffing coating. The article comprises (a) a wood substrate having at least one major surface; (b) an anti grain puffing coating directly applied on the major surface of the wood substrate, formed from an aqueous dispersion of siloxane; and (c) one or more coatings applied on the anti grain puffing coating, formed front an aqueous coating composition, wherein the siloxane contains one or snore hydrophobic group and one or more hydrophilic group chemically bonded to its molecule skeleton; and wherein the. siloxane has a particle size in the range of 5 to 100 nrrs.
