用于复合材料制品的增粘剂
摘要：
复合材料制品包括多个木质纤维素片和位于多个木质纤维素片上用于粘接多个木质纤维素片的粘合剂体系。粘合剂体系包括粘结剂组分和增粘剂组分。增粘剂组分包括丙烯酸类或苯乙烯-丁二烯聚合物。增粘剂组分可用于在复合材料制品的制备期间维持多个木质纤维素片的定向。复合材料制品可以是各种工程木质纤维复合材料，例如碎料板。
摘要（英）：

A composite article comprises 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 comprises a binder component and a tackifier component. The tackifier component comprises an acrylic or a styrene -butadiene polymer. The tackifier component is useful for maintaining orientation of the plurality of lignocellulosic pieces during manufacture of the composite article. The composite article may be various engineered lignocellulosic composites, such as particleboard.
