Embodiment 1- Embodiment 9
[0068] Above-mentioned embodiment 1-embodiment 9 carries out test according to following method respectively:
[0069] Test method for residual adhesive level of pressure-sensitive adhesive products, the test method includes the following steps:
[0070] 1) Selection of test boards;
[0071] 2) Set the test plate parameters: the surface tension of the test plate is 32-50mN / m; the size of the test plate is ≥150mm×35mm; the thickness of the test plate is ≥50μm;
[0072] 3) Make the assembly: the pressure-sensitive adhesive test piece to be tested and the test plate are pasted by a cylindrical steel roller covered with rubber by manual or motorized methods. The quality of the paste is tested with the pressure-sensitive adhesive. It is qualified if there are no air bubbles and false pasting after the parts are pasted; the diameter of the steel pressure roller is 100mm, the width is 200mm, and there is no unevenness on the surface; the pressure-sensitive adhesive test piece is lon...
Embodiment 10- Embodiment 19
[0080] Test method for residual adhesive level of pressure-sensitive adhesive products, the test method includes the following steps:
[0081] 1) Selection of test board: smooth polyester board is used as the test board,
[0082] 2) Set the parameters of the test plate: reduce the surface tension by coating the surface with chemical substances (such as coating different doses of silicone oil or non-polar emulsion; adjust the surface tension of the test plate to 32mN / m ( Example 10), 34mN / m (Example 11), 36mN / m (Example 12), 38mN / m (Example 13), 40mN / m (Example 14), 42mN / m (Example 15), 44mN / m (embodiment 16), 46mN / m (embodiment 17), 48mN / m (embodiment 18), 50mN / m (embodiment 19) are used as pressure-sensitive adhesive products residual glue level gradient test; The size is 160mm×50mm; the thickness of the test plate is 1000μm;
[0083] 3) Make the assembly: the energy efficiency label applied to an electrical appliance is pasted on the test board by a cylindrical steel rolle...

Abstract
The invention discloses a method for testing the grade of adhesive residue of a pressure-sensitive adhesive product. The test method comprises the following steps: (1) selecting a test board, namely utilizing one of a metal plate, a metal sheet, a plastic board and a plastic plate as the test board; (2) setting parameters of the test board, wherein the surface tension of the test board is 32-50mN / m, the size of the test board is greater than or equal to 150mm*35mm, and the thickness of the test board is greater than or equal to 50 microns; (3) manufacturing an assembly, namely adhering a to-be-tested pressure-sensitive adhesive test piece onto the test board so as to form the assembly; (4) processing the assembly, namely respectively placing the assembly in a thermo-hygrostat which has temperature higher than 30 DEG C and humidity higher than 60% or a thermostat at a temperature lower than 30 DEG C; and (5) performing a stripping test, namely stripping the test piece in the assembly treated in the step (4) from the test board. The test method disclosed by the invention can be used for determining the grade of adhesive residues of the pressure-sensitive adhesive, thus determining the viscous force of the pressure-sensitive adhesive product and the adhesion quality of the pressure-sensitive adhesive product and an adhered object.
Description
technical field [0001] The present invention relates to the technical field of detection methods, in particular to a method for testing the residual adhesive level of pressure-sensitive adhesive products. By the method, the residual adhesive level of pressure-sensitive adhesive is determined, thereby determining the quality of the adhesive base of the pressure-sensitive adhesive product itself and the relationship between the pressure-sensitive adhesive product and the pressure-sensitive adhesive product. The bonding quality between the objects to be pasted and the scope of application of the product. Background technique [0002] The adhesive properties of pressure-sensitive adhesive products are determined by the adhesive properties of its main material - pressure-sensitive adhesives. When a pressure-sensitive adhesive product is in use, as long as its pressure-sensitive adhesive layer is in contact with a clean surface to be adhered, and a certain pressure is applied, the...
