Description
Technical field
The invention belongs to coating shear strength test technical field, particularly relate to a kind of aluminium flake substrate for coating shear strength test and test sample thereof.
Background technology
The shearing sample that the coating prepared under being applicable to rated condition of shear strength test is bonding with two parallel plates (or porcelain plate).Coating comes bonding with glass plate (or porcelain plate) by sulfuration.Sample is the bridging arrangement that coating is clipped between two parallel plates (or porcelain plate).The bonding plane of sample applies tensile shear power, measures the maximum tension shearing force of sample.Maximum tension shearing force on sample unit bonding plane is coating and glass plate (or porcelain plate) bonding tensile shear strength.
In the preparation of existing shear resistance sample, as shown in Figure 1, form one shear sheet by a glass sheets 2 is bonding with a slice aluminium sheet 1, with coating 3 to be measured, the glass-board surface of two of said structure shearing sheets is bonded together formation sample.Prepare sample and should use fixture, to ensure that sample is correctly bonding, the dislocation of bonding plane is not more than 0.2mm.When testing, regulate temperature to 23 ± 2 DEG C of experimental enviroment, humidity, to 40-70%, with length and the width of gage measuring sample bonding plane, is accurate to 0.05mm, is fixed on the upper and lower holder of tension tester by the aluminium sheet of sample end.Start testing machine, clamper is loaded sample with the speed of (50 ± 5) mm/min, until coating destroys completely with the bonding of glass plate, the Failure type of the maximum load that record sample destroys and bonding plane.
The defect of above-mentioned prior art is when holder aluminium sheet termination stretches, two power effects are not point-blank, there is moment of torsion, adopt original method film-making, moment of torsion is large, and (active line of power is calculated with the center line of aluminium sheet, when sheet thickness is 5mm, about 12mm), in testing, easily cause that aluminium sheet is bending, warpage, and aluminium sheet and glass plate bonding plane destroy, make net result invalid (be effective to destroy between two pieces of glass plates), or test data is inaccurate, the situations such as data fluctuations is large.
Summary of the invention
For above-mentioned prior art defect, the present invention proposes a kind of aluminium flake substrate for coating shear strength test and test sample thereof, comprise: be arranged on the side of aluminium flake substrate for mosaic glass plate or the caulking groove of porcelain plate and the one or more movable buckles for clamping this glass plate or porcelain plate after placing glass plate in caulking groove or porcelain plate, movable buckle comprises the pivotable movable clamping sheet being fixed on caulking groove side and the clip being fixed on caulking groove opposite side, and described movable clamping sheet is provided with the clamping slot that can coordinate with clip.
The thickness that described aluminium flake substrate is provided with the side of caulking groove is less than the thickness of the side not arranging caulking groove.
The Thickness Ratio that described aluminium flake substrate is provided with the side of caulking groove does not arrange the little 1.0mm of thickness of the side of caulking groove.
Described test sample is made up of the aluminium flake substrate that two parts are superimposed, two aluminium flake substrates are arranged in the mode that caulking groove is relative, the respective caulking groove of two aluminium flake substrates is inlaid with glass plate or porcelain plate, has the coating to be measured glass plate or porcelain plate part bonded together in the caulking groove of two aluminium flake substrates between incrusted glass plate or porcelain plate.
Described coating to be measured is Prospect on RTV of Solidified Silicon Rubber in Normal Temperature for Insulator.
The present invention is by being mounted in aluminium flake substrate by glass plate, (active line of power is calculated with the center line of aluminium sheet to reduce moment of torsion, when sheet thickness is 5mm, about 6mm), the simultaneously increase of the thickness of aluminium flake and the mode of inlaying make more to be not easy distortion, are convenient to dismounting simultaneously, can repeatedly use, without the need to bonding, not only solve the inaccurate problem of test data, also improve the convenience of test simultaneously.
The present invention may extend to the test of the shear resistance of any other bonding test material in addition, and adopting aluminium flake to make substrate is because glass plate cannot clamp, and can skid in testing, broken; If run into equally other materials when cannot directly test, also can adopt the method, make substrate to realize test with aluminium flake.Must carry out bonding in former method, when test material and aluminium flake poor attachment, cannot test; In of the present invention improving one's methods, employing is inlayed, the mode of compression, just can solve very well.Such as Thickness Ratio does not arrange the little 0.5 ~ 1.5mm of thickness of the side of caulking groove, preferably 0.8 ~ 1.2mm, more preferably from about 1.0mm.
Accompanying drawing explanation
Fig. 1 a and Fig. 1 b is vertical view and the side view of prior art shear resistance sample.
Fig. 2 a and Fig. 2 b is the present invention for the aluminium flake substrate vertical view of coating shear strength test and side view.
Fig. 3 a and Fig. 3 b is test sample vertical view of the present invention and side view.
Embodiment
Below in conjunction with accompanying drawing, embodiment is elaborated.
