Embodiment 1

[0043] The sample used for the peel strength test of paper-based materials, including: the first base material 1, the main body of paper-based material 3 and the second base material 2 which are stacked in sequence; The base material main body 3 is connected by an adhesive layer 4, and the adhesive layer 4, the first base material 1 and the second base material 2 all cover the paper base material main body 3; wherein, in the first base material 1 and the second base material 2 At least one of them is a flexible material, and the flexible material is provided with a leading end 5 relative to the main body 3 of the paper-based material for applying force during the test.

[0044] The present invention provides a kind of suitable for paper base, especially the grammage is less than 500g / m 2 Or the test samples of paper base and related paper base products with a thickness of less than 0.5mm, through the setting of the base material on both sides, play a role in protecting the mai...

Embodiment approach

[0046] like figure 1 As shown, it shows the first embodiment in which both the first base material 1 and the second base material 2 are flexible materials. In this way, the first base material 1 and the second base material on the top and bottom layers in the figure The base material 2 is provided with a lead-out end 5, and by applying force to both, the top and bottom layers of the paper-based material body 3 are respectively subjected to forces from the top and bottom through the adhesive layer 4, thereby achieving the purpose of peeling; and During this process, due to the connection established between the first base material 1 and the second base material 2 with the paper base material main body 3 through the adhesive layer 4, the top and bottom layers of the paper base material main body 3 are stabilized, thereby avoiding Damage and breakage are avoided, and only the peeled state is achieved.

[0047] or, as in figure 2 As shown, it shows the second specific embodimen...

Embodiment 2

[0056] The method for making a sample for the peel strength test of the paper-based material comprises the following steps: respectively covering the first base material 1 and the second base material 2 on both sides of the paper-based material main body 3; The adhesive establishes respectively the connection of the first base material 1 and the paper base material main body 3, and the connection of the second base material 2 and the paper base material main body 3; Cutting with the second base material 2 to obtain a sample of required size.

[0057] Wherein, at least one of the first base material 1 and the second base material 2 is a flexible material, and the flexible material is drawn out relative to the edge of the paper base material main body 3 to form a force application position during the test.

[0058] As described in the above-mentioned embodiment, the adhesive can be purchased from the adhesive tape, and in this way, the part where the flexible material is led out...

Abstract

The invention relates to the technical field of material testing, in particular to a sample piece for testing the peel strength of a paper-based material, which comprises a first base material, a paper-based material main body and a second base material, the first base material and the second base material are respectively connected with the paper-based material main body through a bonding layer, and the bonding layer, the first base material and the second base material all cover the paper-based material main body; at least one of the first base material and the second base material is a flexible material, and the flexible material is provided with a leading-out end relative to the paper-based material body. The sample piece suitable for testing the peel strength of the paper-based material is provided, the paper-based material main body in the test is protected through the arrangement of the base materials on the two sides, and the paper-based material main body is prevented from being damaged or broken in the test process, so that the overall performance index of a product is accurately tested. The invention further discloses a manufacturing method and a testing method of the sample piece for testing the peel strength of the paper-based material.

Description

technical field [0001] The invention relates to the technical field of material testing, in particular to a sample, a manufacturing method and a testing method for peeling strength testing of paper-based materials. Background technique [0002] Peel strength is a measure that can be found in different items, specifically when measuring various processed products in coated abrasives such as abrasive cloth, sandpaper, plastic film and scouring pads, etc. , requires targeted methods or tools. [0003] For example, for abrasive cloth products, there is currently a "peel strength" evaluation method, the principle of which is to measure the peeling force after the adhesive is used to bond the abrasive cloth on a plane; Peel strength between multiple layers of paper. However, no matter which method is used above, the matrix is ​​required to have a certain strength and thickness, and the matrix generally will not be damaged during the test. The matrix includes materials such as cl...
