Foreword
This standard equivalently adopts the to the part 8. 180° adhesion test method
of JIS Z 0237-1991 Pressure-sensitive adhesive tape test method.
1. Differences between this standard and part 8 of JIS Z 0237.
(1) JIS Z 0237 specifies that the material of the test plate is SUS 304, which
is the domestic brand Cr18Ni9. This standard specifies that the material
of the test plate is 0Cr18Ni9 or 1Crl8Ni9Ti.
(2) JIS Z 0237 does not clearly specify the preparation of double-sided
pressure-sensitive adhesive tape specimen.
2. This standard mainly revises the following contents of GB/T 2792-1981.
(1) ADD the specimen preparation and test of double-sided pressure-
sensitive adhesive tapes.
(2) ADD the specifications for the material of test plates.
(3) ADD the treatment of the surface of the test plate and test plate cleaning
before the test.
(4) CHANGE the hardness of the roller wrapping rubber (Shore A) from 60°
± 5° to 80° ± 5°.
This standard will replace GB/T 2792-1981 as of the date of implementation.
This standard was proposed by the Chemical Industry Ministry of the People's
Republic of China.
This standard shall be under the jurisdiction of the National Adhesives
Standardization Technical Committee.
This standard was drafted by Shanghai Rubber Products Research Institute.
The main drafter of this standard. Shen Zhengying.
This standard was first published in 1981.
For this standard, the National adhesives Standardization Technical Committee
is entrusted for its interpretation.
Test method for peel strength of
pressure-sensitive tape at 180° angle
1 Scope
This standard applies to the 180° peel strength determination for the single,
double-sided pressure-sensitive adhesive tape and stainless steel plate, it is
also applicable to other materials, such as PVC, ABS, PE, etc.
2 Normative references
The provisions contained in the following standards are incorporated into this
standard and constitute the provisions of this standard. At the time of publication,
the versions indicated were valid. All standards will be revised and all parties
using this standard shall explore the possibility of using the latest version of the
following standards.
GB/T 3280-1992 Stainless steel cold rolled steel plate
JB/T 7499-1994 Waterproof sandpaper
3 Definitions
This standard uses the following definition.
Peel strength
Under the specified peeling conditions, the load that can be withstood per unit
width when the adhesive sample is separated, expressed in kN/m.
4 Test devices
4.1 Compression roller (as shown in Figure 1)
Where.
S - Area within the value range of the recording curve, mm2;
L - Length within the value range of the recording curve, mm;
b - The actual width of adhesive tape, mm;
C - Load per unit height of recording paper, kN/m.
8.3 Reading method calculation
Within the peeling value range, read a number at the interval of 20 mm, read 4
numbers in total, calculate the average value.
8.4 The number of specimens in each group shall be not less than 3, and the
test results shall be expressed as the arithmetic mean of peel strength.
9 Test report
The test report includes the following several parts.
a) The number and name of this standard;
b) Description of the pressure-sensitive adhesive tape for test, including the
type, source, manufacturer's grade, batch size, lot number, etc.;
c) Materials to be bond, surface treatment methods;
d) The material grade of the test plate;
e) Test environment and test date;
f) Standing time after sample preparation.
g) The type of failure of the specimen;
h) Test results and calculation methods;
i) Test phenomena that need to be reported;
j) Any inconsistency with the prescribed steps that may affect the test results.
