Disclosed herein is a method of manufacturing a bonded particulate article by admixing particulate material with a binder system, the binder system being formed by admixing a polyol selected from the group comprising a saccharide, a saccharide polymer, and a glyco protein with a heterocyclic compound of the formula
wherein R1 and R2 are, independently, aryl of from 6 to 12 carbon atoms, alkyl of from 1 to 6 carbon atoms or substituted alkyl of from 1 to 6 carbon atoms wherein the substituting group is hydroxy, alkoxy of from 1 to 6 carbon atoms, hydroxyalkoxy of from 1 to 6 carbon atoms, cyano, carboxy, carbalkoxy of from 1 to 7 carbon atoms or carbamoyl, or when R1 is -CxH2x-, R2 is -CxH2xO-, x being from 1 to 6, X is oxygen, sulfur or imino and Z is a divalent bridging radical, with a solvent, and an acid effective to control the rate of crosslinking between said polyol and said heterocyclic compound; forming the admixture in a shape; and curing to form the bonded article.
本发明公开了一种通过将微粒材料与粘合剂体系混合来制造粘合微粒制品的方法,该粘合剂体系是通过将选自包括糖、糖
聚合物和糖蛋白的多元醇与式中的
杂环化合物混合而形成的。
其中 R1 和 R2 独立地为 6 至 12 个
碳原子的芳基、1 至 6 个
碳原子的烷基或 1 至 6 个
碳原子的取代烷基,其中取代基为羟基、1 至 6 个
碳原子的烷
氧基、1 至 6 个
碳原子的羟基烷
氧基、
氰基、羧基、1 至 7 个
碳原子的羧基烷
氧基、当 R1 为-CxH2x-,R2 为-CxH2xO-,x 为 1 至 6,X 为
氧、
硫或亚
氨基,Z 为二价桥基时;将混合物制成一定形状;并固化以形成粘合制品。
