Wherein first test board is a square, and the length of side is 80cm, and thickness is 2mm; The second test board length is 160mm, and width is 80mm, thickness 2mm, the position of the osculatory of second test board and counterweight hitch point as shown in Figure 4, all the other are with embodiment 1.
Represented the paste position of tested sample on test board in the present embodiment among Fig. 6, if the width of test board is L, then the width of tested sample is 1/2nd L, its length is one and 1/2nd L, wherein the stickup length of tested sample 25 on first test board 24 is a L, stickup length on the second test board 23-2 is 1/2nd L, leaves the space about 2mm between first and second test boards.
Specimen preparation and testing procedure in the present embodiment method of testing are substantially the same manner as Example 1, and difference is second test board
Be fixed on by securing member on the fixed mount of support, the paste position of tested sample on test board undertaken by position shown in Figure 6, and all the other processes are identical with embodiment 1 with step, no longer repeat at this.
Present embodiment is used for the situation that the actual face of sealing of simulation test is a right angle (90 °) (as common employed commodity inner packaging box), under the action of gravity of counterweight, second test board is divided into axle with the blade portion of vertical support frame, lateral rotation takes place (among the figure for being axle with the edge of a knife, rotate from right to left), seal the actual loading situation of pressure sensitive adhesive tape or pressure-sensitive label with imitation commodity inner packaging box, timing is measured tested sample and is sealed the time of being drawn back, and is the sealing-strength of tested sample.
When adopting the present invention to test the sealing-strength of pressure sensitive adhesive tape or pressure-sensitive label, can select different method of testings according to the different using method of pressure sensitive adhesive tape or pressure-sensitive label.If the actual face of sealing is a plane, can select embodiment 2 described 180 ° of sealing-strength method of testings; If the actual face of sealing is a right angle, can select embodiment 3 described 90 ° of sealing-strength method of testings.During actual test, the employed time when only considering that pasting a sample is drawn back, survey suitable timer range by choosing, the test selectable range is extremely wide, and short tested several seconds, and the long hundreds of tested hour does not wait.
Because the present invention is when testing tested sample, the method of testing of selecting is very near the actual use stressing conditions of pressure sensitive adhesive tape or pressure-sensitive label product, therefore, test the inherent quality that the data that obtain more can reflect pressure sensitive adhesive tape or pressure-sensitive label product efficiently and accurately.
The present invention can be widely used in the sealing-strength test that various pressure sensitive adhesives seal adhesive product (as the joint sealing pressure sensitive adhesive tape or seal label etc.).
