Detection method for fogging performance of protective film

The invention relates to the technical field of plastic protective films, in particular to a method for detecting fogging performance of a protective film. In the embodiment of the invention, the protective film can be pasted on the surface of the pasted object with the surface cleanliness reaching the standard, then the pasted object pasted with the protective film is placed under the preset test condition to be stored for preset time, and the protective film on the surface of the pasted object is torn off; in a dark environment, a pasted object is irradiated by strong light, and whether the surface of the pasted object has a fogging phenomenon or not is observed under the irradiation of the strong light. Therefore, the detection of the fogging performance of the protective film can be realized. 本申请涉及塑胶保护膜技术领域，特别是涉及一种保护膜发雾性能的检测方法。在本申请的实施例中，可以将保护膜粘贴在表面清洁度达标的被贴物表面，然后将粘贴有保护膜的被贴物置于预定的测试条件下存放预定时间后，撕去被贴物表面的所述保护膜；在黑暗环境中，通过强光照射被贴物，在强光的照射下观察所述被贴物表面是否出现发雾现象。因此，本申请实施例可以实现对保护膜发雾性能的检测。
