Drawings
Fig. 1 is a schematic view of a high-strength PP regenerated winding film provided in an embodiment of the present invention.
In the figure:
1. a substrate layer; 2. an elastic layer; 3. a waterproof layer; 4. and (4) an antistatic coating.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1, the high strength PP regeneration winding film that provides in this embodiment, including substrate layer 1, elastic layer 2, waterproof layer 3 and antistatic coating 4, substrate layer 1, elastic layer 2, waterproof layer 3 and antistatic coating 4 are coincide by lower supreme in proper order, the material of elastic layer 2 is the conifer fibre, the conifer fibre is the main material that is used for making the kraft paper, the conifer fibre is longer, can play the effect of reinforcing winding film intensity, setting through the elastic layer, the tensile strength and the penetration resistance of PP winding film have been improved, the damaged condition is torn to the winding film has been reduced, the availability factor of winding film has been improved.
In order to improve the fiber strength of the elastic layer 2, the conifer fibers of the elastic layer 2 are further treated with caustic soda and sodium sulfide, and the conifer fibers are treated with caustic soda and sodium sulfide chemicals, so that the chemical effects of the conifer fibers are mild, the original strength of the wood fibers is less damaged, and the treated conifer fibers are tightly dependent on the fibers.
In order to improve the stability of the elastic layer 2, the elastic layer 2 is further in a grid shape.
In order to increase the water resistance of the wrapping film, further, the water-proof layer 3 is a polymer plastic matrix composite.
In order to enhance the connection among the layers of the winding film, further, the base material layer 1, the elastic layer 2, the waterproof layer 3 and the antistatic coating layer 4 are bonded by heat pressing.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
