The invention performs printing performance test on the black single-sided tape prepared in the embodiment 2, and adopts a dyne pen for test, and the test result shows that: the black single-sided tape prepared in example 2 had a dyne value of 59.
Example 3
2% Of carbon black color paste with 93% of model Dari refined A-601 polyurethane resin and 20% of solid content is stirred at 1000rpm for 20min, and 3% of printable functional auxiliary agent (starch, ethylene glycol phenyl ether, 2-dimethoxy propane and 2-ethylhexanol with the mass ratio of 1:1:1 and the granularity of 18-40 micrometers) is added and stirred at 1000rpm for 20min; and finally adding 2% of toluene diisocyanate curing additive, stirring for 20min at 1000rpm, and filtering by using two layers of 400-mesh metal filter screens to obtain the black non-sticky printable ink coating.
Mixing 76% of acrylic adhesive, 6% of carbon black color paste with the solid content of 20%, 14% of ethyl acetate and 4% of hexamethylene diisocyanate to obtain black acrylic sizing material;
And mixing the model Dari refined A-601 polyurethane resin with the mass ratio of 100:8 and a toluene diisocyanate curing agent to obtain the non-adhesive polyurethane resin sizing material.
Coating one side of the transparent base film with black acrylic rubber material, and curing to form a black acrylic rubber layer with the thickness of 15 micrometers; and sequentially coating a non-adhesive polyurethane sizing material and a black non-adhesive printable ink coating on the other surface of the transparent base film, curing to form a 4-micrometer non-adhesive polyurethane adhesive layer and a 20-micrometer black non-adhesive printable ink coating, and then coating a single-sided release film on the black acrylic adhesive layer to obtain the black single-sided adhesive tape with the super-strong printing function on the surface.
The invention tests the printing performance of the black single-sided adhesive tape prepared in the embodiment 3 by using a dyne pen, and the test result shows that: the black single-sided tape prepared in example 3 had a dyne value of 61.
From the above embodiments, the present application provides a black single-sided tape with super-strong printing function, comprising a release layer, a black acrylic adhesive layer, a transparent base film layer, a non-adhesive polyurethane adhesive layer and a black non-adhesive printable ink coating layer, which are sequentially contacted. The black single-sided adhesive tape has better printing force by arranging the black non-sticky printable ink coating as a printing layer. In addition, there is no need to provide a protective layer on the outside of the black non-tacky printable ink coating. The experimental results show that: the dyne value of the black single-sided tape provided by the application is 52-61.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
