用于粘合纤维模制件的双组份聚氨酯粘合剂
摘要：
本发明涉及一种双组份聚氨酯粘合剂，其包含NCO/OH比为0.9∶1至1.5∶1的多元醇组分和由多异氰酸酯制得的交联组分，所述多元醇组分含有：2至30重量％的至少一种分子量大于1000g/mol的聚酯二醇；5至35重量％的至少一种3-至14-官能多元醇；5至35重量％的疏水性多元醇；2至65重量％的附加添加剂或辅助剂，其中总和结果是100％，其中交联的粘合剂的Tg高于50℃。
摘要（英）：

A two-component polyurethane adhesive comprising a polyol component, which contains 2 to 30 wt. % of at least one polyester diol having a molecular weight greater than 1000 g/mole, 5 to 35 wt. % of at least one 3 to 14 functional polyol, 5 to 35 wt.-% hydrophobic polyols, 2 to 65 wt. % further additives or auxiliary agents, wherein the sum is to result as 100%, and a cross-linking component made of polyisocyanates in a NCO/OH ratio of 0.9:1 to 1.5:1, wherein the cross-linked adhesive has a Tg greater than 50 DEG C.
