Three, optics reflecting film test
1, baking: optics reflecting film 1-37 among the foregoing description 1-37 and the optics reflecting film among the comparative example 1-7 are put into baking oven (SC101-18, Cixi City baking oven factory), baking temperature is made as 150 ℃, film is after certain hour (being made as 1h, 3h, 5h, 10h, 20h, 50h, 80h, 100h respectively) baking, close baking oven, treat film cooling back taking-up film, carry out the warpage degree test.
2, warpage degree test:
The warpage degree of optics reflecting film of the present invention refers to after film is heated perk, film is put on the surface level, the peak of film perk leaves the distance (herein because the warpage degree of film much larger than the thickness of film, so ignore film thickness) of original surface level.As shown in figure 12, the optics reflecting film before the warpage takes place in 120 expressions, and 120 ' is the optics reflecting film after the generation warpage, and distance h is the warpage degree of optics reflecting film 120 '.The numerical value of h is more little, shows that the deformation resistance of optics reflecting film is good more.
Testing tool: feeler gauge (precision is 0.01mm, and range is 1.0mm); Rule (precision is 0.5mm, and range is 300mm).
When the warpage degree of optics reflecting film during, adopt feeler gauge to test its warpage degree less than 1mm; When the warpage degree of optics reflecting film during, adopt rule to test its warpage degree greater than 1mm.Concrete method of testing is as follows:
The optics reflecting film 1-37 among the test implementation example 1-37 and the warpage degree of the optics reflecting film among the comparative example 1-7 compare its warpage degree respectively.
