Adhesion test method is as follows:
Detect styrene-acrylic emulsion and UV finishing coat adhesive force reference standard GB/T9286-1998.Specific embodiment are as follows: existed with cross-cut tester
10 × 10 (100) 1mm × 1mm small grids are drawn on test sample surface, and each scribing line should deep and paint bottom；Use hairbrush
The fragment of test zone is cleaned down；Tested small grid is firmly clung with the gummed paper of 3M600 gummed paper or equal efficiency, is used in combination
Erasing rubber firmly wipes adhesive tape, to increase the contact area and dynamics of adhesive tape and tested region；Adhesive tape one end is held, is being hung down
Histogram shuts down rapidly gummed paper to (90 °), and same position carries out 2 identical tests.Ranking score are as follows: the complete light in the edge of 5B notch
Sliding, grid edge does not have any peeling；4B has small pieces peeling in the intersection of notch, and actual spoilage≤5%:3B is cut in the area Hua Ge
The edge and/or intersection of mouth, which have, to be peeled off, and area is greater than 5%~15%；2B has part peeling or whole sheet along notching edge
It peels off or partial grid is peeled off by full wafer.The area of peeling is more than 15%~35%1B；0B notching edge sheet peeling/or one
A little grids partly or entirely peel off, and area is greater than the 35%~65% of the area Hua Ge.
Following table is the attachment test result of the embodiment of the present invention and comparative example:
