From the specimen size that power is required for particular requirement, it is adaptable to the test of raw material supplied materials.And the shading rubber belt size after being die cut is wide
Degree and difference in length are very big, therefore can not unify peel test force standard.For the shading rubber belt after cross cutting, adhesive tape is quickly judged
Difference would generally use hand to touch adhesive tape, and sticky difference is distinguished with feel, and feel judges also tested person personnel, the shadow of pressing dynamics etc.
Sound is larger, judges more subjective；Easily obscure after test is excessive in addition, cause erroneous judgement.
The content of the invention
The technical problems to be solved by the invention there is provided a kind of determination methods of the sticky difference of two-sided tape, for mould
Adhesive tape after cutting, the sound that the present invention is sent when being peeled off using adhesive tape and adherend body judges difference that adhesive tape two sides is sticky
It is different, it is bigger according to the stronger stripping sound of test commensurateiy wide adhesive tape viscosity, compared with the method that existing feel distinguishes sticky difference, this
The determination methods of invention are accurately objective, simple and quick, do not result in erroneous judgement.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of determination methods of the sticky difference of two-sided tape, it comprises the following steps：The adhesive tape front is fitted in a flat board
On, stripping tape or flat board obtain first and peel off sound；The adhesive tape back side is fitted on a flat board, stripping tape or flat
Plate, obtains second and peels off sound；Compare the first stripping sound and second and peel off the power of sound, quickly to judge the adhesive tape
The sticky difference of front and back.
In the present invention, the sticky difference refer to the adhesive tape two sides viscosity difference one times and more than.
In the present invention, the flat board is the non-layer upper surfaces of PET or steel plate.
In the present invention, the adhesive tape is shading rubber belt.
In the present invention, the shading rubber belt is black glue.
The present invention has the advantages that：For the adhesive tape after cross cutting, the present invention peels off when institute using adhesive tape with adherend body
The sound sent come judge adhesive tape two sides viscosity difference, according to test commensurateiy wide adhesive tape viscosity it is stronger stripping sound it is bigger, with
The method that existing feel distinguishes sticky difference is compared, and determination methods of the invention are accurately objective, simple and quick, do not result in mistake
Sentence, reduce product fraction defective and probability is reprocessed in reduction, when one times of biadhesive strength difference and the above, reprocess probability relative
The method that existing feel is distinguished reduces more than 50%.
Embodiment
The adhesive tape marked for the adhesive tape after cross cutting or inviscid difference, quickly judges that adhesive tape difference would generally be touched with hand
Adhesive tape, sticky difference is distinguished with feel, and feel judges also tested person personnel, and the influence of pressing dynamics etc. is larger, judges compared with based on
See；Easily obscure after test is excessive in addition, cause erroneous judgement.
For above-mentioned technical problem, the present invention proposes a kind of judgement side of the sticky difference of quick detection two-sided tape
Method.To ensure that the size of adhesive tape after peeling off all is to separate adhesive tape from the release surface such as PET layer upper surfaces or release liners, the glue of this process
There will not be sound with peeling off.It is existing and the adhesive tape after cross cutting stripping can not carry out initial bonding strength again or tensiometer is tested
There is the sticky difference that adhesive tape two sides is mainly distinguished by feel, but subjective easily cause erroneous judgement.The present inventor is unintentionally
The adhesive tape being die cut after peeling off is fitted with the non-layer upper surfaces of PET and peeled off again, finds what is sent when different sticky adhesive tapes are peeled off
Peel off intensity of sound to have any different, viscosity is stronger, and its stripping sound with adherend body is bigger, and relative another side viscosity declines one
Half and it is more after adhesive tape there is no sound when peeling off.The sound that is sent when can then be peeled off using adhesive tape and flat board judges adhesive tape
The difference of two sides viscosity, specifically, comprises the following steps：The adhesive tape front is fitted on a flat board, stripping tape or flat
Plate, obtains first and peels off sound；The adhesive tape back side is fitted on a flat board, stripping tape or flat board, obtains second and peel off
Sound；Compare the first stripping sound and second and peel off the power of sound, quickly to judge the viscous of the adhesive tape front and back
