Abstract: Embodiments of the present invention provide an adhesive requiring a low modulus of elasticity and a liquid epoxy resin composition that is used for the adhesive thereof. The liquid epoxy resin composition not only exhibits flexibility or a low modulus of elasticity to prevent magnet cracking in the manufacturing of a rotor, using a ferrite magnet in particular, but also does not undergo a decrease in weight while exhibits minimal dimensional change. This is true even if the liquid epoxy resin is immersed in an automatic transmission fluid, for a long period of time, in an environment which is used as a rotor. The liquid epoxy resin composition according to the embodiments of the present invention includes a bisphenol A type epoxy resin, an epoxy resin containing a polyoxyalkylene structure, and a curing agent as essential components, used for the adhesive.

Abstract translation: 本发明的实施方案提供了一种需要低弹性模量的粘合剂和用于其粘合剂的液体环氧树脂组合物。 液体环氧树脂组合物不仅具有柔软性或低弹性模量，以防止制造转子时的磁体破裂，特别是使用铁氧体磁体，而且在显示最小的尺寸变化的同时也不会发生重量的减轻。 即使液体环氧树脂在用作转子的环境中长时间浸入自动变速器油中也是如此。 根据本发明实施方案的液体环氧树脂组合物包含双酚A型环氧树脂，含有聚氧化烯结构的环氧树脂和用作粘合剂的必要组分的固化剂。
