Problems solved by technology

[0005] However, looking at the international and Chinese existing technologies, for pressure-sensitive adhesive products pasted on the object to be pasted, within the time specified in the contract or the time expected by consumers, or at least one year or longer, when the pressure-sensitive adhesive product is torn apart Or when the label is removed or discarded, the test method or test standard that does not leave adhesive on the object is still a blank spot in this field.

Embodiment 1- Embodiment 9

[0068] The above Examples 1 to 9 were tested according to the following methods:

[0069] Pressure-sensitive adhesive product residual glue grade test method, the test method includes the following steps:

[0070] 1) Selection of test board;

[0071] 2) Set the test board parameters: the surface tension of the test board is 32-50mN / m; the size of the test board is ≥150mm×35mm; the thickness of the test board is ≥50μm;

[0072] 3) Making the assembly: the pressure-sensitive adhesive test piece and the test board to be tested are glued manually or motorized with a cylindrical steel pressure roller coated with rubber, and the quality of the glue is tested with the pressure-sensitive adhesive After pasting, there is no air bubbles and virtual sticking phenomenon. The steel pressure roller has a diameter of 100mm, a width of 200mm, and no unevenness on the surface. The pressure-sensitive adhesive test piece is long, and the pressure-sensitive adhesive is tested during the pasting process. ...

Embodiment 10- Embodiment 19

[0080] The test method for the residual glue level of pressure-sensitive adhesive products. The test method includes the following steps:

[0081] 1) Selection of test board: use smooth polyester board as test board,

[0082] 2) Set the parameters of the test panel: reduce the surface tension by coating the surface with chemical substances (such as coating different doses of silicone oil or non-polar emulsion; the method of coating the polar emulsion to adjust the surface tension of the test panel 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 (Example 16), 46mN / m (Example 17), 48mN / m (Example 18), 50mN / m (Example 19) as a pressure-sensitive adhesive product residual adhesive grade gradient test; The size is 160mm×50mm; the thickness of the test board is 1000μm;

[0083] 3) Making assembly: The energy efficiency label applied to an electrical appliance will be pasted on the test board by manual...

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 pressure-sensitive adhesive product residual adhesive grade test method, by which the pressure-sensitive adhesive residual adhesive grade is determined, thereby determining the adhesive base quality of the pressure-sensitive adhesive product itself and the pressure-sensitive adhesive product The bonding quality between the objects to be affixed and the application range of the product. Background technique [0002] The adhesive properties of pressure-sensitive adhesive products are determined by the adhesive properties of the main material-pressure-sensitive adhesive. When using a pressure-sensitive adhesive product, 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 pressure-sensitive adhesive will wet the surface to be adhered and stick the object firmly to form Practical adhe...
