The obtained double faced adhesive tape of embodiment 1-5 and comparative example 1-4 is tested.Test result is as follows shown in table 1:
Table 1
Note: sample is first cut into the sheet of 33mm × 33mm by falling sphere experiment, is cut then at the four inside 3mm in side edge interior
Portion's rectangular opening, four side right angles are unable to severing, are first pasted on PMMA plate after peeling the sample cut off release material on one side,
The release material for removing another side again is pasted on the rectangle frame position of ABS plate, it is desirable that stickup wants smooth, and bonding area is
360mm2 is placed at room temperature for for 24 hours after the test model prepared is pressed 5s with 10Kg counterweight, then test model is obtained PMMA plate one
It is placed on the ground every sky down and by test position, bilateral tubing one end of a length of 125cm is disposed vertically in test mould
Then the surface of type test position allows No. 25 steel balls from bilateral tubing upper end center position free-falling shock-testing position,
Falling ball impact test for several times is carried out according to shock-testing result, at most carries out 15 Secondary Shocks tests.If test model is rushed in 15 times
Open, record falling sphere number, if after 15 times test model be not rushed to open if need to only record falling sphere number.
Sample, is first cut into the sheet of 20mm × 20mm, is pasted onto after taking side release film off by dynamic shearing test
On 304 steel disc bottom position of 20mm × 100mm × 2mm specification, other side release film is then taken off, by same specification
The bottom position of 304 steel discs is bonded with glue surface, bonding area 400mm2, by the test model prepared 10Kg counterweight pressure
It is placed at room temperature for after 5s for 24 hours, 180 ° of shearing forces, unit Mpa is then tested with 10mm/min with puller system.
Solvent resistance test will take out room temperature after doing jig immersion alcohol (75% concentration) for 24 hours that ball falling impact experiment posts
2h is placed, room temperature peeling force is tested, the peeling force being calculated is divided by initial stage peeling force, institute's calculated value >=60%, then solvent resistant
Property OK, on the contrary then NG.
