Entirely, its thickness is tested using calibrator, chooses the sample of film thickness needed for providing, guarantee that effective area is greater than 25cm2, it is made
3 groups of samples；
Step 2: preparing moisture vapor transmission cup: desiccant being put into clean cup ware, additional amount should make desiccant away from sample table
Face about 3mm is advisable；
The cup ware for filling desiccant is put into moisture vapor transmission cup, then moisture vapor transmission cup is put on glass platform, sample is placed on moisture vapor transmission cup
Gland is added in addition fixing the position of sample with guider ring after cup ring in center；
Guider ring carefully is removed, the sealing wax of melting is poured in the groove for being filled in moisture vapor transmission cup, is not allowed after sealing wax solidification
It cracks and bubble；
After wax solidification to be sealed, gland and cup platform are removed, the sealing wax for being sticked to moisture vapor transmission cup side and bottom is removed；
Step 3: weighing the moisture vapor transmission cup sealed；
Step 4: moisture vapor transmission cup being put into climatic chamber (60 DEG C/90%RH), is taken out afterwards for 24 hours, 23 ± 2 DEG C of environment are put into
Under drier in, balance 30min after weighed；
Step 5: moisture vapor transmission cup is reentered into climatic chamber after weighing, be per interval time for weighing twice later for 24 hours,
48h or 96h；
Step 6: step 5 is repeated, until mass incremental can terminate to test no more than 5% twice for front and back.
The above technical solution is further limited in that calculation method are as follows: steam penetrating capacity WVT=24 Δ m/ (A
t)
In formula: WVT: steam penetrating capacity, g/m2·24h；
T: the interval time twice after mass incremental is stable, h；
Mass incremental in the Δ m:t time, g；
A: the area of sample moisture vapor permeable, m2。
The above technical solution is further limited in that vapor transfer rate is excessive as samples in step 5, it also can be to initial balance
Time and weighing interval time adjust accordingly, but should control moisture vapor transmission cup increment not less than 5mg.
The above technical solution is further limited in that when weighing every time, moisture vapor transmission cup sequencing should be consistent in step 6,
The weighing time must not exceed the 1% of interval time, and the desiccant in slight vibration moisture vapor transmission cup is answered to keep it mixed up and down after weighing every time
It closes, desiccant moisture absorption total increment must not exceed 10%.
The invention has the following advantages: a kind of permeable rate test method of adhesive of the present invention solves adhesive not
The problem of easily carrying out permeability rate test；It is easy to operate, convenient and low in cost.
