资源简介:
Binder compositions are described that contain (1) a reducing sugar and (2) a reaction product of a urea compound and an aldehyde-containing compound. A specific example of the binder compositions include dextrose and an imidazolidine compound such as 4,5-dihydroxyimidazolidin-2-one. The binder compositions may be applied to collections of fibers and cured to form a fiber-containing composite, such as fiberglass insulation.
本文描述了一类粘合剂组合物(binder compositions),其组分包含(1)还原糖(reducing sugar),以及(2)脲类化合物(urea compound)与含醛化合物(aldehyde-containing compound)的反应产物。该类粘合剂组合物的具体实例包括右旋糖(dextrose)以及咪唑烷类化合物(imidazolidine compound),例如4,5-二羟基咪唑烷-2-酮。此类粘合剂组合物可施用于纤维集合体,经固化处理后可制得含纤维复合材料,例如玻璃纤维保温棉(fiberglass insulation)。
