Description
技术领域technical field
本实用新型涉及一种试验用夹具，特别涉及胶黏剂粘接的柔性非金属薄膜与刚性金属材料之间的胶黏剂低温剥离强度测试工装夹具，适用于胶黏剂粘接的柔性非金属膜与刚性金属材料之间室温～4.2K剥离强度的测试。The utility model relates to a fixture for testing, in particular to a fixture for testing the low-temperature peeling strength of an adhesive between a flexible non-metallic film bonded by an adhesive and a rigid metal material, and is suitable for flexible non-metallic films bonded by an adhesive The test of the peel strength between the film and the rigid metal material at room temperature to 4.2K.
背景技术Background technique
目前，随着胶黏剂种类的增多及应用领域的不断扩大，不同种类的胶黏剂不仅应具有良好的导电、导热、绝缘等性能，还需要有良好的粘接强度。特别是随着胶黏剂在低温环境下的应用增多，此环境下众多的非金属材料与金属材料除了通过胶黏剂来实现导热、导电、绝缘等要求外，还需要胶黏剂具有牢靠的粘接力，防止彼此剥离脱落。这就需要通过试验获得利用胶黏剂粘接在一起的非金属材料与金属材料之间的剥离强度。如何获得胶黏剂在低温环境下的剥离强度，特别是柔性非金属薄膜通过胶黏剂粘接的刚性金属之间的低温剥离强度，是一个急需解决的问题。At present, with the increase in the types of adhesives and the continuous expansion of application fields, different types of adhesives should not only have good electrical conductivity, thermal conductivity, insulation and other properties, but also need to have good bonding strength. Especially with the increasing application of adhesives in low temperature environment, many non-metallic materials and metal materials in this environment not only need adhesives to meet the requirements of heat conduction, electric conduction, insulation, etc. Adhesive force to prevent peeling off from each other. This requires testing to obtain the peel strength between non-metallic materials and metal materials bonded together by adhesives. How to obtain the peel strength of adhesives at low temperature, especially the low-temperature peel strength between rigid metals bonded by flexible non-metal films through adhesives, is an urgent problem to be solved.
目前GB/T 7122-1996里面介绍了胶黏剂剥离强度的室温测试工装，但是该测试工装不适合在低温环境中应用。一方面是室温测试工装不能够根据实际测试的需求提供不同剥离角度的剥离测试；另一方面是室温测试工装需要的测试区域过大，由于测试区域必须是稳定的低温温度场，特别是有些低温剥离测试需要在77K～4.2K的温度下进行，这就要求测试的空间尽可能的缩小，以实现稳定控制温度场并尽可能的减少战略资源液氦的消耗量从而节约测试的成本等。基于此，有必要研制适用于低温环境下的胶黏剂剥离测试工装。国内目前还没有报道胶黏剂低温环境下的剥离试验工装，研制适合胶黏剂室温～4.2K的剥离强度的试验工装显得尤为迫切。At present, GB/T 7122-1996 introduces the room temperature test tool for adhesive peel strength, but this test tool is not suitable for application in low temperature environment.

Based on this, it is necessary to develop an adhesive peel test tool suitable for low temperature environment. At present, there is no report on the peeling test tooling of adhesives in low temperature environment in China, and it is particularly urgent to develop test tools suitable for the peeling strength of adhesives at room temperature ~ 4.2K.
