Description
Technical field
This utility model belongs to coating shear strength test technical field, particularly relates to a kind of aluminium flake substrate for coating shear strength test and test sample thereof.
Background technology
Shear strength test is applicable to the coating of preparation under rated condition and the shearing sample that two parallel plates (or porcelain plate) are bonding. Coating is next bonding by vulcanizing with glass plate (or porcelain plate). 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 tensile shear strength bonding with glass plate (or porcelain plate).
In prepared by existing shear strength sample, as it is shown in figure 1, constituted a shearing sheet by a glass sheets 2 is bonding with a piece of aluminium sheet 1, with coating 3 to be measured, the glass-board surface of the two of said structure shearing sheets is bonded together one sample of composition. Preparing sample and should use fixture, to ensure that sample is correctly bonding, the dislocation of bonding plane is not more than 0.2mm. When test, regulating the temperature of experimental enviroment to 23 �� 2 DEG C, humidity, to 40-70%, by the length and width of gage measuring sample bonding plane, is accurate to 0.05mm, is fixed on the upper and lower holder of tensile testing machine by the aluminium sheet of sample end. Start testing machine, make clamper with the speed of (50 �� 5) mm/min, sample be loaded, until coating destroys completely with the bonding of glass plate, record the maximum load of sample destruction and the Failure type of bonding plane.
Above-mentioned prior art has the drawback that 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 big, and (position of power is calculated with the centrage of aluminium sheet, when sheet thickness is 5mm, about 12mm), in testing, it is easily caused aluminium sheet bending, warpage and aluminium sheet and glass plate bonding plane destruction so that final result invalid (to destroy between two pieces of glass plates be effective), or test data are inaccurate, the situations such as data fluctuations is big.
Utility model content
For above-mentioned prior art defect, the utility model proposes a kind of aluminium flake substrate for coating shear strength test and test sample thereof, including: it is arranged on the caulking groove for mosaic glass plate or porcelain plate of the side of aluminium flake substrate and for placing one or more movable buckles of this glass plate of clamping or porcelain plate after glass plate or porcelain plate in caulking groove, described movable buckle includes being fixed on the pivotable movable clamping sheet of caulking groove side and being fixed on the clip of caulking groove opposite side, and described movable clamping sheet is provided with the clamping slot that can coordinate with clip.
Described aluminium flake substrate is provided with the thickness thickness less than the side being not provided with caulking groove of the side of caulking groove.
Described aluminium flake substrate is provided with the thickness 1.0mm less of the thickness of the side being not provided with caulking groove of the side of caulking groove.
Described test sample is made up of the aluminium flake substrate of two part overlappings, two aluminium flake substrates are arranged in the way of 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.
This utility model by being mounted in aluminium flake substrate by glass plate, (position of power is calculated with the centrage 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 inlayed make more to be not easy deformation, simultaneously facilitate dismounting, can repeatedly use, without bonding, not only solve the test inaccurate problem of data, also improve the convenience of test simultaneously.
Additionally this utility model may extend to the test of the shear strength of any other bonding test material, adopts aluminium flake to make substrate and is because glass plate and cannot clamp, and can skid in testing, broken; If running into equally other materials when cannot directly test, it would however also be possible to employ the method, making substrate with aluminium flake and realizing test. Former method must carry out bonding, when testing material with aluminium flake poor attachment, it is impossible to test; In improved method of the present utility model, employing is inlayed, the mode of compression, it is possible to solve very well. Such as thickness 0.5��1.5mm less of the thickness of the side being not provided with caulking groove, it is preferable that 0.8��1.2mm, more preferably from about 1.0mm.
