In the process of preparation sticking agent constituent, what have in the aqueous vapor entering reaction environment, or solvent itself contains moisture.White atomizing takes place, as if using the not good problem of display effect that in optical component, can cause if react with the sticking agent constituent in aqueous vapor easily in coating process.The composition of degree, speed and the sticking agent constituent of aqueous vapor and the reaction of sticking agent constituent has relation.Result by table 1 can know that the sticking agent constituent of embodiment 1 to 6 is difficult for producing reaction with aqueous vapor.
4. [initial stage adhesion (pulling force) test]
Adhesion is by puller system (Dachang is made by wide rhenium instrument) test.The PET adhesive film that has adhering layer on the surface is cut into the wide long strip type test piece of 25mm.After dicing film in the test piece removed; Using 2Kg spreading roller to make test piece stick together face, to stick in TN on glass; And after the environment held of 23 ± 1 ℃/50 ± 2%RH (relative humidity) 20 minutes, utilize puller system to measure test piece and stick together 180 degree adhesions in the face of glass with the speed that draws high of 300mm/min.
The result is presented in the table 1, and appraisal procedure is:
X: less than 500gf/25mm
Zero: greater than 500gf/25mm
The adhesion of test piece representes that less than 500gf/25mm adhesion is not enough; The element that may cause the sticking agent attaching rocks the top in being transported to the client way quite makes sticking agent separate with element, or in airtight high temperature transportation means, presents the phenomenon of peeling off because of temperature contrast.Result by table 1 can know, the adhering layer of embodiment 1 to 6 has excellent adhesion (greater than 500gf/25mm), even therefore under hot and humid harsh environment, still can avoid the risk of peeling off.
5. [gel fraction]
After the oven dry of sticking agent constituent, get the sample of suitable weight and put into ETHYLE ACETATE immersion 24 hours, filter with filter screen then.To there be residue filter screen from the teeth outwards to place in 110 ℃ the baking oven after 2 hours; The weight of residue (with whole filtering net (the comprising residue) weighing of taking away, then the weight that obtains being deducted the original weight of filter screen (before filtering)) is promptly obtained gel fraction divided by the weight of primary sample.
The result is presented in the table 1, and appraisal procedure is:
X: less than 80%
Zero: greater than 80%
Gel fraction is bigger, and the cross-linking density between the expression sticking agent is higher.Cross-linking density is high more, is entangled with manyly more, and the intensity of glue is strong more, and therefore the back is difficult for producing the space under hot and humid environment, and produces the defect problem that foams etc.
The solvent composition of table 1 embodiment and comparative example and the character of material
Though the present invention discloses as above with preferred embodiment; Right its is not in order to limiting the present invention, anyly is familiar with this art, do not breaking away from the spirit and scope of the present invention; When can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the claim person of defining.
