采用含单宁和多官能醛的路易斯酸催化的粘合剂组合物制造的复合产品
摘要：
采用含一种或更多种单宁，一种或更多种多官能醛，和一种或更多种路易斯酸的粘合剂组合物制造的复合产品及其制造方法。该方法可包括接触多个基底与该粘合剂组合物，和至少部分固化该粘合剂组合物，生产复合产品。一种或更多种多官能醛化合物可包括(1)两个或更多个碳原子和两个或更多个醛官能团,或(2)两个或更多个碳原子，至少一个醛官能团，和除了醛官能团以外的至少一个官能团。至少一个醛官能团中的碳原子可具有与第一单宁分子的第一化学键，和与(a)第一单宁分子,(b)第二单宁分子,或(c)至少一个醛官能团的氧原子的第二化学键。
摘要（英）：

Composite products made with binder compositions that include one or more tannins, one or more multifunctional aldehydes, and one or more Lewis acids and methods for making same. The method can include contacting a plurality of substrates with the binder composition and at least partially curing the binder composition to produce a composite product. The one or more multifunctional aldehyde compounds can include (1) two or more carbon atoms and two or more aldehyde functional groups, or (2) two or more carbon atoms, at least one aldehyde functional group, and at least one functional group other than an aldehyde functional group. A carbon atom of at least one aldehyde functional group can have a first bond with a first tannin molecule and a second bond with (a) the first tannin molecule, (b) a second tannin molecule, or (c) an oxygen atom of the at least one aldehyde functional group.
