A preparation method of a medical glove quick-binding adhesive tape attaching adhesive tape comprises the following steps:
1) a steel wire scraper direct coating method is adopted to coat a layer of release agent on the OPP film, so that the adhesive force of the base material is enhanced; the coating temperature is 105 ℃, and the coating speed is 40 m/min;
2) a steel wire scraper direct coating method is adopted, and a layer of primer is coated on the other surface of the OPP film, so that the adhesive force of the base material is enhanced; the coating temperature is 105 ℃, and the coating speed is 40 m/min;
3) and (3) coating a pressure-sensitive adhesive on the primer by adopting a transfer method to obtain the medical glove quick-binding adhesive tape attaching adhesive tape, wherein the coating temperature is 105 ℃, and the coating speed is 38 m/min.
Comparative example 1
The preparation method of the common medical glove quick-binding adhesive tape on the market comprises the following steps: the pressure sensitive adhesive is coated directly on the base film.
The test results of the examples and comparative example 1 are shown in Table 1, comparing the situation of tearing the tape after 12h of glove application:
TABLE 1
| Detachment situation | Degumming situation | |
| Example 1 | Does not fall off | Without degumming |
| Example 2 | Does not fall off | Without degumming |
| Example 3 | Does not fall off | Without degumming |
| Example 4 | Does not fall off | Without degumming |
| Comparative example 1 (primer-free) | Falling off | Degumming |
As can be seen from Table 1, the examples with the primer do not have the phenomena of falling off and degumming, which shows that the primer has good protective effect on the permeation of the plasticizer, enhances the adhesive force of the primer on the base material, and effectively ensures that the glove adhered with the adhesive tape for a long time does not have the phenomena of falling off and degumming.
The above description is only exemplary of the present invention and is not intended to limit the scope of the present invention, which is defined by the claims appended hereto, as well as the appended claims.
