Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A waterproof leather release paper comprising: base paper 11, smooth layer 12, thermoplastic resin layer 13 and sticky layer 14. The base paper 11 is provided with a pattern 111 having a concave-convex shape. Smooth layer 12 is disposed over pattern 111 for water resistance. The thermoplastic resin layer 13 is provided on the surface of the base paper 11 for moisture resistance. The adhesive layer 14 is disposed between the base paper 11 and the thermoplastic resin, and is used for adhering the thermoplastic resin to the base paper 11. In this embodiment, through set up smooth layer 12 on concave-convex pattern 111, improved waterproof leather from smooth degree of type paper, when having water on smooth layer 12, also can flow away, prevent that water from oozing on the paper, improved waterproof leather from the waterproof performance of type paper, simultaneously, set up thermoplastic resin layer 13 on body paper 11 through gluing layer 14, thermoplastic resin layer 13 is the material of not afraid of water to waterproof leather from the dampproofing and waterproofing's effect of type paper has been improved.
