Description
Technical Field
The utility model relates to the technical field of laminating paper, in particular to high-toughness waterproof laminating paper.
Background
The laminated paper is a composite material which coats plastic particles on the surface of paper through a casting machine, can resist oil, is relatively waterproof, can be thermally sealed and resists high temperature, can be used for foods, chemical products, wood products, paper and the like, and is mainly used for food industry packaging.
At present, the laminated paper adopts a traditional structure, namely, high polymer such as PE (polyethylene) with water resistance and high temperature resistance is sprayed and foamed on the surface of a substrate paper to form a water-resistant and high temperature-resistant protective layer, but the structure has relatively weak strength and limited bearing capacity, so that the high-toughness waterproof laminated paper is provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide high-toughness waterproof laminating paper, which improves the toughness and the waterproof performance, greatly improves the overall performance and meets the use requirement.
In order to achieve the purpose, the utility model provides the following technical scheme: the straw pulp paper comprises a plurality of layers of composite straw pulp paper, a sodium polyacrylate water-absorbing resin layer and a film coating layer, wherein the plurality of layers of composite straw pulp paper comprises a layer of straw pulp paper, two layers of straw pulp paper, pulp silk and an adhesive, the pulp silk is positioned between the layer of straw pulp paper and the two layers of straw pulp paper, the straw pulp paper is combined by the adhesive, the cost of the straw pulp paper is low, the production process is simple, the overall toughness can be greatly improved after the pulp silk is added, the upper surface and the lower surface of the straw pulp paper are both provided with the sodium polyacrylate water-absorbing resin layers, and the film coating layer is arranged on the surface of the sodium polyacrylate water-absorbing resin layer.
Preferably, the upper surface of the straw pulp paper layer and the lower surface of the straw pulp paper layer are rough surfaces, so that the adhesion of the sodium polyacrylate water-absorbing resin layer is facilitated.
Preferably, the pulp silk can adopt straw pulp silk, and each silk is between 0.03 and 0.05 mm.
Preferably, the adhesive is a food grade silicone adhesive.
Compared with the prior art, the utility model has the beneficial effects that: the utility model has better toughness and waterproof performance, greatly improves the overall performance and can meet the use requirement.
Drawings
FIG. 1 is a schematic structural view of the high-toughness waterproof laminated paper of the present invention.
In the figure: 1-one layer of straw pulp paper, 2-two layers of straw pulp paper, 3-pulp silk, 4-adhesive, 5-sodium polyacrylate water-absorbing resin layer and 6-laminating layer.
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.
Referring to fig. 1, the present invention provides a technical solution: comprises a plurality of layers of composite straw pulp paper, a sodium polyacrylate water absorption resin layer 5 and a film lamination layer 6,
the multilayer composite straw pulp paper consists of a layer of straw pulp paper 1, a layer of straw pulp paper 2, pulp silk 3 and an adhesive 4, wherein the pulp silk 3 is positioned between the layer of straw pulp paper 1 and the layer of straw pulp paper 2;
the first layer of straw pulp paper 1, the second layer of straw pulp paper 2 and the pulp silk 3 are compounded through an adhesive;
the sodium polyacrylate water absorption resin layer 5 is positioned on the surface of the straw pulp paper;
the film lamination layer 6 is positioned on the surface of the sodium polyacrylate water absorption resin layer 5.
Furthermore, the upper surface of the one-layer straw pulp paper 1 and the lower surface of the two-layer straw pulp paper 2 are rough surfaces, so that the adhesion of the sodium polyacrylate water-absorbing resin layer 5 is facilitated, the rough surfaces of the straw pulp paper can be designed into lines, and the straw pulp paper also has the adhesion stability.
Furthermore, the straw pulp paper is low in cost and simple in production process, and the overall toughness can be greatly improved after the pulp filaments 3 are added.
Furthermore, the pulp silk 3 can adopt straw pulp silk, each silk is 0.03-0.05mm, the straw pulp silk can be replaced by harmless glass fiber silk, and the material component of the glass fiber in the harmless glass fiber silk is silicon dioxide, so that the harmless glass fiber silk has no harm to human bodies.
Further, the adhesive 4 is a food grade silica gel adhesive.
Furthermore, the sodium polyacrylate water-absorbing resin layer 5 is a synthetic resin which can absorb a large amount of moisture to swell and can keep the moisture not to flow out, and has very good waterproof performance.
Further, the film coating layer 6 is made of polyethylene material, and is coated on the surface of the sodium polyacrylate water-absorbing resin layer 5 by professional equipment after being converted into liquid flowing glue, so that uniform fusion is realized.
The high-toughness waterproof laminating paper structure provided by the utility model has high-efficiency toughness and waterproof performance, the structural strength is improved, and the requirements of more industries are favorably met.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
