(Normative)
Anti-blocking test method
A.1 principle
Specimen coating surface after bonding to each other, subject to a certain period of heating, pressure, and then observe the separation of the bonding layer, the adhesion between the coating
degree.
A.2 Instruments
Constant temperature oven with ventilation.
A.3 Sample Preparation
Sample size. 60mm × 60mm.
A.4 Test procedure
Take 6 samples, coating and coating on a total of 3 groups. The three groups of samples were respectively sandwiched in a 60 mm × 60 mm × 3 mm glass plate,
And the load on the glass plate 30N load, into the temperature (80 ± 2) ℃ constant temperature oven with a blowing device, heated 24h after
The sample was cooled at room temperature for 30 min and then the sample was peeled off slowly.
A.5 test results
The anti-blocking properties of each sample were evaluated as follows.
--- No adhesion. When the sample is separated, the coating surface has no signs of adhesion.
--- Light adhesion. When the sample is separated, a certain degree of adhesion occurs on the surface of the coating, but the coating is not damaged.
--- Adhesion. the coating surface is difficult to separate or separation of the coating layer or part of the coating is damaged.
To 3 groups of samples in the most serious assessment of adhesion, as the test results.
