Description
Technical field
The invention belongs to tackifier stickiness field tests, specifically is a kind of method that adopts the vertical tension method testing original viscosity of adhesive.
Background technology
At present, in the industry, testing original viscosity of adhesive adopts following four kinds of methods more:
1, the spin plane stops test method(s): this method is adopted and formulates one of the national standard that can test into pressure sensitive adhesive goods original viscosity by the U.S., be ASTMD-3121-73, during test, the steel ball that with diameter is 11.1mm is from highly rolling down horizontal by the top of the inclined slope of α angle for 65.1mm, on the gluing face of the pressure sensitive adhesive goods of smooth horizontal positioned, roll across, because of the retardance of the stickiness of pressure sensitive adhesive stops, distance L is measured for this original viscosity energy, and the more little performance of L is good more.
2, the spin slope stops test method(s): will be directly during test roll down from the hang plate that is 30 ° of angles with horizontal plane successively from big to small through different a series of steel balls, through the smooth gluing face that is placed on the pressure-sensitive tape of hang plate lower end, find out wherein stickiness retardance because of pressure sensitive adhesive and can stop at maximum steel ball on the gluing face fully, measure the original viscosity of the gluing face of pressure-sensitive tape with the ball N of steel ball.The method is as the national standard of the original viscosity of the gluing face of China and Japan's test pressure-sensitive tape
3, cushion rubber tension method: the long sticking tape sample of the wide 300mm of 25mm is curved glue towards outer pyriform circle, it is suspended on the tension tester, descend with certain speed then, allow the sticking tape circle contact with the breadboard surface, when area to be pasted reached 25mm * 25mm, testing machine stopped to descend, and rises with certain speed then at once, cushion rubber is stripped down from breadboard, survey and peel off the original viscosity that numerical value is the gluing face of pressure-sensitive tape.
4, peel off method fast for 90 °: during test with pressure sensitive adhesive tape under the situation that does not apply any pressure, only depend on self gravitation to stick on the smooth stainless steel breadboard surface, carry out 90 ° at tension tester with certain speed then and peel off, measured peel strength numerical value is the original viscosity energy of this pressure-sensitive tape at once.
In above method commonly used, there has been following deficiency in method 1,2:
1) owing to be subjected to the influence of acceleration of gravity, it is also different that therefore different test sections clings the needed viscous force just of bead when falling for bead.
2) be subjected to objective factor to influence error very big, for example the friction factor of the homogeneity of the flowability of temperature, tackifier, coating and tackifier is all bigger to its influence, therefore the test result dispersiveness is too big, and particularly the test result to synthetic rubber-like and acrylic tackifier is very big in actual feel difference.
There has been following deficiency in method 3,4:
1) rigidity of base material and flexibility have a significant impact test result.
2) different test sections and peel angle are also changing, so the mensuration numerical value of different test sections may differ bigger.
Therefore the method for testing of prior art all is difficult to test out accurately the parameter value of tack, and the ordinary production of enterprise has been caused many adverse effects, has directly influenced the stability of end product quality.
Summary of the invention
The objective of the invention is to solve above-mentioned deficiency of the prior art, prior art is improved, providing a kind of can glue obedient service check to single sign, and test number is accurate, the method for the employing vertical tension method testing original viscosity of adhesive that error is little.
For achieving the above object, the present invention is achieved by the following technical solutions:
Be a kind of method that adopts the vertical tension method testing original viscosity of adhesive, comprise tension tester, the present technique main points are to finish by following steps:
1) on tension tester by the clean steel ball of backguy vertical hanging;
2) sticking tape is flattened on the article carrying platform of clean steel ball below;
3) start tension tester, clean steel ball is at the uniform velocity descended with the speed of 250～350mm/min, extremely clean steel ball remains static on the sticking tape surface, upwards promotes clean steel ball to clean steel ball with 250～350mm/min speed fast by tension tester then and leaves sticking tape.
Through repeatedly experiment, decline of clean steel ball the best or pulling speed are 300mm/min.
In order to guarantee test accuracy, backguy is inelastic conventional backguy, and the diameter of institute's employing steel ball is 6～10 millimeters, and weight is 8～12 grams.
After the present invention improved prior art, prodigiosin is enough to glue obedient service check to single sign, and test number is accurate, the advantage that error is little.
