The invention relates to an ether epoxy flexibilizer and a preparation method and application thereof, the chemical structure is as shown in the specification: # imgabs0 #, the value range of n is 3-40, and R is a molecular structure containing a benzene ring, a condensed ring or a plurality of connected rigid rings. By adding a small amount of the epoxy flexibilizer, the flexibility of the epoxy resin can be greatly improved while the thermal performance of the epoxy resin is maintained, and meanwhile, the strength and modulus of the epoxy resin can be improved. 一种醚类环氧增韧剂及其制备方法和应用，化学结构如下所示：#imgabs0#其中，n的取值范围为3～40，R为含有苯环、稠环或几个刚性环相连的分子结构。本发明添加少量的此种环氧增韧剂在保持其热性能下，可大幅提高环氧树脂的柔韧性，同时还能提高其强度和模量。
