采用拉伸试验机对环氧腰果酚涂层的应力-应变性能进行了测试。制备工艺：将环氧腰果酚与双酚A型环氧树脂复合，用四面制备器刮涂在PE膜上固化。将固化的涂层与PE膜分离，并切割成50*2（mm）样品用于拉伸测试。制备步骤，醇钠：环氧化腰果酚：1.5：1，搅拌4h，离心40min。精制后的环氧化腰果酚与双酚A型环氧树脂复配。制备环氧化腰果酚涂层，测拉伸。重复测试。

The stress-strain properties of epoxy cashew phenolic coating were tested using a tensile testing machine. Preparation process: Compound epoxy cashew phenol with bisphenol A epoxy resin, and use a four sided preparator to scrape and cure on the PE film. Separate the cured coating from the PE film and cut it into 50 * 2 (mm) samples for tensile testing. Preparation steps: Sodium alcohol: epoxidized cashew phenol: 1.5:1, stirred for 4 hours, and centrifuged for 40 minutes. The refined epoxidized cashew nut phenol is compounded with bisphenol A epoxy resin. Preparation of epoxidized cashew phenol coating and measurement of tensile strength. Repeat the test.
