Comparative example one: as a first comparative example, a combination glue for manufacturing a strip nail disclosed in Chinese patent application publication No. CN103923594A was used.
Comparative example two: in contrast to example one, the intermediate layer is absent.
The detection method comprises the following steps:
20 strip nails in a row are respectively bonded on the bonding agents of the first embodiment and the first and the second comparative examples, after 24 hours of bonding, force is applied on the adhesive tape to ensure that the strip nails do not bear any acting force in the vertical direction, and the detection time is respectively 1 day, 3 days, 7 days, 14 days and 30 days.
(1) Adhesion: through the test of the detection method, whether the strip nails fall off or not is observed;
(2) and (3) vertical stiffness: through the test of the detection method, whether the binder keeps a standing state or not is observed;
(3) thickness: the thickness of the example and comparative example one was measured with a vernier caliper.
The results of the adhesion test are shown in the following table:
according to the upper table, the row nails bonded by the embodiment are high in bonding firmness and can be prevented from falling for a long time.
The results of the measurement of the vertical stiffness are shown in the following table:
as can be seen from the above table, the paper tape of the present embodiment has good support for the strip nails, and the paper tape of the comparative example collapses after being bonded for 7 days, and cannot maintain a standing state for a long time.
The results of the thickness measurements are shown in the following table:
