Description

Adhesive bonding force testing device and testing method

Technical field

The invention relates to the field of adhesive testing, in particular to an adhesive bonding force testing device and testing method.

Background technique

Adhesives are materials that have good adhesive properties and can form a film between the surfaces of two objects and firmly bond them together. They are generally composed of bonding substances, curing agents, toughening agents, diluents and modification It is formulated with ingredients such as chemicals, and is widely used in packaging, electronics, building materials, automobiles and transportation, machinery manufacturing, new energy, medical and health, aerospace and other fields.

Adhesive force is the most important indicator of adhesive performance. At present, the measurement method of interlayer adhesion is mostly concentrated in the field of electronic components, such as the preparation of copper-clad laminates for electronic components. The invention patent with authorization number CN101017131B discloses one. This kind of interlayer adhesion test method and manufacturing tool has simple process, low cost, and strong practicability, but it is limited to PCB board and is not suitable for the test of adhesion between flexible materials.

The adhesive force of the flexible material is usually tested by a peeling test method. During the test, the flexible material is fixed on a solid substrate, and peeling is generally performed at a 180° or 90° state. At present, both the 180° test and the 90° test require separate equipment, additional laboratory space and personnel training, which consumes manpower and material resources, and the test angle cannot be changed, is not flexible enough, and for flexible materials with less deformability For example, for elastoplastic materials, even if the 90° peel angle is used for the peel test, there are cases where the product is not resistant to bending and stress cracks.

The US patent with grant number US09945772B2 discloses a method for testing the adhesion between layers of semiconductor materials, which can measure the adhesion between layers with a certain flexible material, but the method and equipment are aimed at the field of electronic components. The precision is high and the production cost is high. For the chemical industry, the adhesion test is generally for horizontal comparison and does not require too precise measurement. Therefore, this method is not suitable for promotion and use in the chemical industry.

Boeing has published a patent with application number CN201810478864.2, which provides an adhesive testing system and method that can accurately perform peeling tests on flexible materials using a tensiometer, eliminating the buckling of the substrate, and passing tensile forces at different angles. , Displacement and angle data are used to measure the size of the adhesive force, but, similarly, the cost of this equipment is high and it is not suitable for promotion.

In addition to the above problems, the current measuring method of adhesive bonding force is mainly aimed at molded products. The test samples are obtained by cutting or polishing the molded products. However, for adhesive manufacturers, In the process of adhesive formulation design, it is also necessary to conduct multiple lateral bonding force comparison experiments to obtain the optimal performance plan. Therefore, the preparation method of the test sample is also important, and there are fewer references on the sample preparation method.

The angle is more suitable for rigid materials that do not have deformation characteristics. For rigid materials, the implementation is completely the same, but the length of the adhesive coating area during sample preparation should be determined according to the standard size in order to accurately obtain peeling length.

Data processing method:

The adhesive 503 in Examples 1-4 can be replaced with adhesives of different formulations or commercially available adhesives for comparison experiments to obtain lateral comparison data.

Fix the peel test time T and the tensile force F of the tensile tester 1, and record the peel length ΔS of the test sample 5. The sample peel length ΔS is the reading S ₀ of the scale line 403 on the sample substrate 4 at the initial peeling, and at the end of the peeling _{The difference between the readings S 1} of the scale line 403 on the sample substrate 4, that is, ΔS=S ₁ -S ₀ , because the elastic material has tensile deformation characteristics, the tensile distance data on the tensile tester 1 cannot be regarded as the standard.

The work W used for peeling can be obtained by calculating W=F·△S. The smaller the value of W, the greater the bonding force of the adhesive.

Fix the peel test tensile force F, and record the time T it takes for the tensile tester 1 to peel the test sample 5 to the specified length ΔS. The longer the time T, the greater the bonding force of the adhesive.

The above-mentioned embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the above-mentioned embodiments, and any other changes, modifications, substitutions, combinations, etc. made without departing from the spirit and principle of the present invention Simplified, all should be equivalent replacement methods, and all are included in the protection scope of the present invention.
