CN106928657A 一种用于光弹实验测试的环氧树脂板的生产方法 无效 - 驳回

一种用于光弹实验测试的环氧树脂板的生产方法
摘要：
本发明公开了一种用于光弹实验测试的环氧树脂板的生产方法，该方法以环氧树脂、顺丁烯二酸酐为、邻苯二甲酸二丁酯和聚酯树脂作为原料，通过对原料用量的调配，并优化混合原料的固化工艺，能够制得不同性能的环氧树脂板。本发明方法简单，原材料丰富，易生产，光学灵敏度高，透明度好，时间边缘效应小，能制作出弹性模量从1.29MPa～57.32MPa，泊松比从0.35～0.68的新型环氧树脂光弹性材料，可用来制作机械、水利、土木等工程中的结构相似模型，是平面应力模型光弹性实验的优良材料。
摘要（英）：

The invention discloses a production method of an epoxy resin board for a photo-elastic experimental test. The method can prepare epoxy resin boards of different performances through a curing process by blending raw materials and optimizing the mixed raw materials by taking epoxy resin, maleic anhydride, dibutyl phthalate and polyester resin as the raw materials. The method disclosed by the invention is simple, raw materials are rich, production is easy, optical sensitivity is high, transparency is good and time fringe effect is small, and a novel epoxy resin photo-elastic material, the elasticity modulus of which is 1.29-57.32MPa and the poisson ratio of which is 0.35-0.68 can be produced. The material can be used for manufacturing structural similar models in engineering such as machinery, hydraulic engineering and civil engineering and is an excellent material for a photo-elastic experiment of a planar stress model.
