1.发明申请Amphiphilic Block Copolymer-Toughened Epoxy Resins and Powder Coatings Made Therefrom 有权两亲嵌段共聚物增韧环氧树脂和粉末涂料公开(公告)号：US20080188626A1
公开(公告)日：2008-08-07
申请号：US11663803
申请日：2005-11-02
CPC分类号： C08L63/00 , C08L71/02 , Y10S525/934 , Y10T428/31511 , C08L2666/02 , C08L2666/22
摘要： A curable resin composition and powder coating compositions made therefrom including (a) an epoxy resin; (b) an amphiphilic block copolymer containing at least one epoxy resin miscible block segment and at least one epoxy resin immiscible block segment; wherein the immiscible block segment comprises at least one polyether structure provided that the polyether structure of said immiscible block segment contains at least one or more alkylene oxide monomer units having at least four carbon atoms; such that when the epoxy resin composition is cured, the toughness of the resulting cured epoxy resin composition is increased; and (c) at least one curing agent required for the manufacturing, application and proper performance of the powder coating. The amphiphilic block copolymer is preferably an all polyether block copolymer such as a PEO-PBO diblock copolymer or a PEO-PBO-PEO triblock copolymer.
摘要翻译： 一种可固化树脂组合物和由其制成的粉末涂料组合物，包括（a）环氧树脂; （b）含有至少一种环氧树脂混溶性嵌段和至少一种环氧树脂不混溶嵌段的两亲性嵌段共聚物; 其中所述不混溶性嵌段部分包含至少一种聚醚结构，条件是所述不混溶嵌段的聚醚结构含有至少一个或多个具有至少四个碳原子的环氧烷单体单元; 使得当环氧树脂组合物固化时，所得固化的环氧树脂组合物的韧性增加; 和（c）粉末涂料的制造，施用和适当性能所需的至少一种固化剂。 两亲性嵌段共聚物优选为全聚醚嵌段共聚物，例如PEO-PBO二嵌段共聚物或PEO-PBO-PEO三嵌段共聚物。
