使用使用拉力试验机的腰果酚基环氧树脂进行应力应变性能测试。在甲苯和戊酸/乙酸的环镜下，将602A与过氧化氢以一定的比例反应4h，反应后的混合物纯化；将602A原料与环氧后的产物与E51按照6：4的质量比复配制备涂层；将涂层裁剪为10×2mmm大小，进行拉伸测试。

Stress-strain performance testing using cashew phenol-based epoxy using a tensile testing machine. Under the ring microscope of toluene and valeric acid/acetic acid, 602A and hydrogen peroxide were reacted in a certain ratio for 4h, and the reacted mixture was purified; The coating was prepared by compounding the raw material of 602A with the epoxy product and E51 according to the mass ratio of 6:4; The coating is cut to a size of 10×2 mm, and tensile test is performed.
