Abstract

The invention discloses high-barrier aluminum-free coating paper. The high-barrier aluminum-free coating paper is composed of a surface effect coating layer, a body paper layer and a back surface coating layer. Coating materials of the surface effect coating layer or/and the back surface coating layer are PVDC emulsion for high-barrier paper. The PVDC emulsion for high-barrier paper comprises, by weight, 60% to 90% of PVDC emulsion, 2% to 10% of acrylate monomer and 8% to 30% of polyurethane prepolymers. According to the high-barrier aluminum-free coating paper, the safe and environment-friendly PVDC emulsion for high-barrier paper is used as barrier coating materials, so that the aluminum-free coating paper has the high dampproof and moisture-keeping effects, and constant moisture in a package is kept. As the PVDC emulsion for high-barrier paper is formed in the mode that graft modification is carried out to introduce polyurethane, the film-forming property and the crystallization completeness of the PVDC emulsion are greatly improved, the PVDC emulsion can form a high-compactness and high-crystallization coating on paper accordingly, and the barrier performance of the paper is improved accordingly.

Description

A kind of high-barrier is without aluminum coated paper
Technical field
The invention belongs to field of packaging material, be specifically related to a kind of high-barrier without aluminum coated paper.
Background technology
Coating paper is to coat a coating on body paper, makes paper and cardboard obtain barrier property by methods such as impregnation processability, paper-plastic stick technology and barrier coatings.Coating paper is the new type of paper of a kind of safety and environmental protection, replaces aluminium lamination with coating layer, reduces the demand to bauxite resource, decrease energy resource consumption, simultaneously self can natural degradation, alleviate the pressure of environment, meet sustainable development, environmental protection national development strategy planning.
But the coating paper existed in industry at present, the problem that such as aluminum-free internal lining paper etc. all exist barrier difference.After removing aluminium lamination, the barrier property of paper significantly declines, and steam and oxygen are all lacked certain barriering effect, therefore limits its development at packaging paper industry.
Summary of the invention
Present invention aim at providing a kind of high-barrier without aluminum coated paper, there is the strongest moistureproof humectation effect, the constant of the interior moisture content of packaging can be kept.
It is an object of the invention to be achieved through the following technical solutions:
A kind of high-barrier is without aluminum coated paper, and by surface effect coating layer, original paper layer, backsize layer forms, it is characterised in that: described surface effect coating layer is or/and the coating materials'use high barrier paper PVDC emulsion of backsize layer；Described high barrier paper PVDC emulsion is made up of the raw material of following percetage by weight: PVDC emulsion 60 ~ 90%, acrylate monomer 2% ~ 10%, base polyurethane prepolymer for use as 8% ~ 30%.
Described original paper layer is any one in soft stationery, art post paperboard, art paper.
Beneficial effects of the present invention: the present invention uses the high barrier paper PVDC emulsion of safety and environmental protection as barrier coat material, makes aluminum-free wrapping paper have the strongest moistureproof humectation effect, can keep the constant of the interior moisture content of packaging.High barrier paper PVDC emulsion used in the present invention, is through graft modification, introduces polyurethane.Greatly improve film property and the completing property of crystallization of PVDC emulsion, make PVDC emulsion can form high fine and close highly crystalline coating at paper, thus improve the barrier property of paper.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure: 1 surface effect coating layer, 2 original paper layers, 3 backsize layers.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment 1:
Be coated with conventional surface effect coating layer 1 on soft paper surface, the backsize layer 3 at soft paper uses high barrier paper PVDC emulsion to be coated.High barrier paper PVDC emulsion is made up of the raw material of following percetage by weight: PVDC emulsion 75%, acrylate monomer 4%, base polyurethane prepolymer for use as 21%.Before and after using high barrier paper PVDC emulsion to be coated with, gained intercepts numerical value contrast as shown in Table 1 and Table 2.
Embodiment 2:
At art post paperboard backsize conventional paper backsize layer 3, the surface effect coating layer 1 in art post paperboard uses high barrier paper PVDC emulsion to be coated.High barrier paper PVDC emulsion is made up of the raw material of following percetage by weight: PVDC emulsion 60%, acrylate monomer 10%, base polyurethane prepolymer for use as 30%.Before and after using high barrier paper PVDC emulsion to be coated with, gained intercepts numerical value contrast as shown in Table 1 and Table 2.
Embodiment 3:
Surface effect coating layer 1 and backsize layer 3 at soft paper all use high barrier paper PVDC emulsion to be coated.High barrier paper PVDC emulsion is made up of the raw material of following percetage by weight: PVDC emulsion 90%, acrylate monomer 2%, base polyurethane prepolymer for use as 8% form.Before and after using high barrier paper PVDC emulsion to be coated with, gained intercepts numerical value contrast as shown in Table 1 and Table 2.
Table 1 water vapour barriering effect
Table 2 oxygen obstruction effect
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, being appreciated that and these embodiments can carry out multiple change without departing from the principles and spirit of the present invention, revise, replace and modification, the scope of the present invention be defined by the appended.
