阅读说明：本技术 具有良好粘附性能的湿固化组合物 (Moisture-curing composition with good adhesion properties ) 是由 S·雷曼 N·库贝 M·施伦普夫 于 2020-04-02 设计创作，主要内容包括：本发明涉及在室温下为液体的、任选糊状的湿固化组合物,其包含：-至少一种含异氰酸酯基团的聚醚氨基甲酸酯聚合物(P1),其聚醚链段中的1,2-亚丙基氧单元的含量为至少80重量％,和-至少一种在室温下为液体且疏水的含异氰酸酯基团的聚合物(P2),其由至少一种单体二异氰酸酯和OH-值在28至120mg KOH/g范围内的疏水二元醇的反应获得,其中聚合物P1和P2彼此分开制备,并且聚合物P1和聚合物P2以70/30至98/2的重量比存在。根据本发明的组合物由于存在疏水聚合物(P2)而在开放时间、粘附、可施加性和耐候性方面具有改进的性能,同时具有不变的良好储存稳定性、固化速度、强度、可拉伸性、弹性和危险物质等级。这种组合物特别适合作为弹性粘合剂用于车辆玻璃更换。(The invention relates to a moisture-curing composition which is liquid at room temperature and optionally pasty, comprising: -at least one isocyanate group-containing polyether urethane polymer (P1) having a content of 1, 2-propyleneoxy units in the polyether segments of at least 80% by weight, and-at least one isocyanate group-containing polymer (P2) which is liquid at room temperature and hydrophobic, and which is obtained from the reaction of at least one monomeric diisocyanate and a hydrophobic diol having an OH "value in the range from 28 to 120mg KOH/g, wherein polymers P1 and P2 are prepared separately from one another and polymer P1 and polymer P2 are present in a weight ratio of 70/30 to 98/2. The compositions according to the invention have improved properties in terms of open time, adhesion, applicability and weathering resistance, owing to the presence of the hydrophobic polymer (P2), while having invariably good storage stability, curing speed, strength, stretchability, elasticity and hazardous substance ratings. The composition is particularly suitable as an elastic adhesive for vehicle glazing replacement.)
