Dry 10~20min is air-dried, the pyroceram plate is taken out, is cooled to room temperature；It is identical finally to cut to obtain size using cut-off knife,
With a thickness of the test piece of 0.05 ± 0.001mm, test piece constant temperature at least 2h under 23 ± 2 DEG C of temperature, relative humidity 50% ± 5%
For use；
The test piece test adjusts the test piece, makes the universal test to clamp the test piece on universal testing machine
The tension uniform of machine is distributed in the test piece, is opened the universal testing machine and is carried out stretching experiment, from described after being completed
Tensile strength and elongation at break are read on universal testing machine.
Further, the swelling mixed slurry obtained in the step b) water bath with thermostatic control is poured on pyroceram plate
On, using drawdown rod by the swelling mixed slurry scratch uniformly, blade coating uniformly after the swelling mixed slurry with a thickness of
0.07mm。
Further, the cut-off knife is that national standard I type dumbbell cut-off knife is obtained with the film-making on sheet-punching machine of national standard Ι type dumbbell cut-off knife
To length 115mm × narrow parallel width 6mm test piece.
Further, the universal testing machine is WD-P1501 electronic universal tester, after being completed, the electronics ten thousand
Energy testing machine can show tensile strength and elongation at break result automatically.
The average value repeatedly tested is taken, as test result.
Advantages of the present invention: PVC paste resin glove material tensile strength and elongation at break test method of the present invention instead of
The complicated technology of PVC paste resin glove line is produced test piece instead of fingerprint in use for laboratory pyroceram plate, and is made
Standby test piece out is similar to PVC finished product gloves performance, simplifies experimental facilities, saves material cost and time cost；Can be
