Aspects described herein generally describe epoxy resins and methods of epoxy resin formation. In some embodiments, a resin includes the reaction product of one or more polythiols, one or more polyepoxides, one or more fillers and one or more amine catalysts. Polythiols have between two and about ten thiol moieties. Polyepoxides have between two and about ten epoxy moieties. One or more amine catalysts of the formula NR1R2R3, wherein each of R1, R2, and R3 is independently linear or branched C1-20 alkyl or two or more of R1, R2, and R3 combine to form cycloalkyl. The resin has a compressive strength of at least 14 ksi at 2% offset at 70°F and at least 8 ksi at 2% offset at 190°F.
本文所述各方面一般描述环氧树脂和环氧树脂的形成方法。在某些实施例中,树脂包括一种或多种聚硫醇、一种或多种聚环氧化物、一种或多种填料和一种或多种胺催化剂的反应产物。聚硫醇具有两个到十个硫醇分子。聚环氧化物有两个到十个环氧基。一种或多种式 NR1R2R3 的胺催化剂,其中 R1、R2 和 R3 中的每一个都是独立的直链或支链 C1-20 烷基,或两个或两个以上的 R1、R2 和 R3 结合形成环烷基。该树脂在 70°F 时,偏移 2% 时的抗压强度至少为 14 ksi,在 190°F 时,偏移 2% 时的抗压强度至少为 8 ksi。
