Embodiment 1

[0026] This embodiment provides a mechanism for testing interlayer adhesion, such as figure 1 and figure 2 As shown, the interlayer adhesion test mechanism includes a fixed base 1, a first puller 2, a second puller 3 and an upper pressing block 4, wherein:

[0027] The above-mentioned fixed base 1 may have a rectangular block structure, and a first sliding groove 12 is provided along the length direction on the fixed base 1 , and the first sliding groove 12 is used for placing the first drawing part 2 and the second drawing part 3 . Specifically, the cross-sectional shape of the first chute 12 is adapted to the cross-sectional shape of the first drawing member 2 and the second drawing member 3, such as the cross-sectional shape of the first sliding groove 12 in this embodiment may be a semicircle , while the cross-sectional shapes of the first drawing member 2 and the second drawing member 3 are circular. The cross-sectional shape of the first chute 12 may also be rectangul...

Embodiment 2

[0040] The difference between the present embodiment and the first embodiment is that the second drawing member 3 of the interlayer adhesion testing mechanism of the present embodiment is fixed on the fixed base 1 , and the second drawing member 3 is not connected with a tension detection member. Specifically, refer to image 3 , the second puller 3 of the interlayer adhesion testing mechanism of this embodiment is fixedly arranged at the first chute 12 , and only the first puller 2 is connected with a tension detection piece. The rest of the structure of the interlayer adhesion testing mechanism in this embodiment is the same as that in Embodiment 1, and will not be repeated here.

[0041] When the above-mentioned interlayer adhesion testing mechanism of the present embodiment is in use, first the first drawing part 2 is placed on the first chute 12, and then one of the film layer and the base layer of the sample to be tested is adhered to the second chute. One drawing part ...

Abstract

The invention belongs to the technical field of adhesive force testing, and discloses an inter-layer adhesive force testing mechanism. The mechanism comprises a fixed pedestal, a first drawing part, asecond drawing part and an upper pressing block, wherein the first drawing part is arranged on the fixed pedestal in a sliding mode, the second drawing part is positioned on the fixed pedestal, the upper pressing block cooperates with the fixed pedestal so as to press the first drawing part and the second drawing part tightly, two opposite end faces of the first drawing part and the second drawing part can be respectively adhered to two sides of a to-be-tested sample part, and the sliding direction of the first drawing part is vertical to the end face, to which the to-be-tested sample part isadhered, of the first drawing part. The first drawing part and / or the second drawing part are / is driven to move in the axial direction through drawing equipment such as a drawing machine so as to enable the first drawing part or the second drawing part to apply drawing force to the to-be-tested sample part, so that the inter-layer adhesive force testing of the to-be-tested sample part is realized. Moreover, the mechanism can guarantee that the drawing force is applied in a direction which is vertical to the inter-layer of the to-be-tested sample part, and then the inter-layer axial directionadhesive force testing of the to-be-tested sample part is realized.

Description

technical field [0001] The invention relates to the technical field of adhesion testing, in particular to an interlayer adhesion testing mechanism. Background technique [0002] The adhesive force of existing test film layer usually adopts adhesive tape method, and adhesive tape method is to adhere the viscous surface of a kind of specific adhesive tape on the film layer surface of sample to be tested, tape is pasted flat, removes all air bubbles, and then Peel off the adhesive tape with a steady pulling force. If the film layer is not peeled off the base layer of the sample to be tested, it means that the film layer has good adhesion. [0003] Although the adhesive tape method can indicate the adhesion of the film layer to a certain extent, the pulling force applied by it cannot be guaranteed to be perpendicular to the surface of the film layer, and the adhesion of the test is not the true sense of the film layer and the film layer of the sample to be tested. Axial adhesio...
