Antiseized isolating membrane on product removes the preparation-obtained water-soluble film of the formula by the embodiment of the present invention 2, and (thickness is
0.3mm) stick, replace antiseized isolating membrane, then according to method described in GB/T23457-2009 carries out cement mortar glass stripping
Experiment.Experimentation is as follows:
According to 5.21 part in GB/T23457-2009, take passages as follows:
Coiled material and cement mortar peel strength test
Cement mortar mix ratio is: strength grade 42.5 Portland cement: medium sand: water=1；2；0.4
Cut the test sample of a size of 300mm × 50mm
Test specimen adhesive surface a size of (100 × 50) mm, goes out the adhesive of test specimen adhesive surface, test specimen is lain in mould
Tool bottom, adhesive surface upward, then by cement mortar mixture import mould, on a vibration table jolt ramming, thickness about 50mm (as
Fig. 3), place in (20 ± 2) DEG C
The 24h demoulding, in standard curing condition maintenance to 7d.
4h placed at (23 ± 2) DEG C by test specimen, is contained in by reinforced cement-mortar board on the fixture of testing machine one end, will be for bonding volume
Material one end overturns in 180 ° of fixtures being clipped in the testing machine other end, makes longitudinal axis and cupping machine and the axle of fixture of test specimen
Line overlaps, such as Fig. 3.Spacing jig is at least 100mm, is not subject to preload.Experiment is carried out in (23 ± 2) DEG C, draw speed
(100±10)mm/min.Record pulling force is until test specimen separates continuously.
Calculating mean peel strength by GB/T328.20-2007, unit is N/mm.
Test taken coiled material sample and should take from same volume coiled material product, then make coiled material experimental sample with water-soluble film
Test, and and contrast with the test result of volume the done sample of coiled material.
Carrying out cement mortar peel strength detection by above said content, acquired results is: thin, water soluble film coiled material sample
For 2.13N/mm, reel material sample is 2.10N/mm.Thus testing result is visible, and water-soluble film of the present invention is applied at coiled material
On, obtain the effect consistent with original product.After illustrating to apply water-soluble film of the present invention, coiled material performance can maintain original effect
And it is unaffected.
Above-described be only presently preferred embodiments of the present invention, all made in the range of the spirit and principles in the present invention appoint
