Lignocellulosic composite articles

A lignocellulosic composite article includes a plurality of lignocellulosic pieces and an adhesive system disposed on the plurality of lignocellulosic pieces for bonding the plurality of lignocellulosic pieces. The adhesive system includes a binder component and a compatibilizer component. An example of a suitable binder component is an isocyanate component， e.g. a diphenylmethane diisocyanate (MDI)， a polymeric diphenylmethane diisocyanate (pMDI)， and combinations thereof. The compatibilizer component includes a trialkyl phosphate. The compatibilizer component is utilized in an amount of at least about 0.5 parts by weight based on 100 parts by weight of the binder component. The compatibilizer component is useful for reducing the amount of press time required during manufacture of the composite article. The adhesive system can include additional components， such as an isocyanate-reactive component. The composite article may be various lignocellulosic composites， such as oriented strand board (OSB)， particleboard (PB)， fiberboard (e.g. medium density fiberboard; MDF)， etc.木质纤维素复合材料制品（lignocellulosic composite article）包含多块木质纤维素构件，以及涂覆于该批木质纤维素构件之上、用于实现构件间粘接的胶粘剂体系。该胶粘剂体系包含黏合剂组分与相容剂组分。合适的黏合剂组分示例为异氰酸酯类组分，例如二苯基甲烷二异氰酸酯（diphenylmethane diisocyanate，MDI）、聚合型二苯基甲烷二异氰酸酯（polymeric diphenylmethane diisocyanate，pMDI）及其复配体系。所述相容剂组分包含磷酸三烷基酯。以100质量份黏合剂组分为基准，相容剂组分的添加量不低于约0.5质量份。该相容剂组分可缩短该复合材料制品生产过程中所需的热压时长。该胶粘剂体系还可包含其他组分，例如异氰酸酯反应型组分。该复合材料制品可涵盖多种木质纤维素复合材料，例如定向刨花板（oriented strand board，OSB）、颗粒板（particleboard，PB）、纤维板（如中密度纤维板（medium density fiberboard，MDF））等。
