Problems solved by technology

[0003] During the processing and transportation of transfer paper, it is often necessary to stack multiple sheets of transfer paper, but the general transfer paper is prone to electrostatic adhesion when stacked, and it needs to be carefully separated during subsequent processing or use, otherwise improper operation It is easy to cause damage to the surface of the transfer paper and be scrapped, which greatly reduces the production efficiency and increases the production cost

preparation example Construction

[0032] The method for preparing the above-mentioned transfer paper according to an embodiment of the present invention includes the following steps S10-S30:

[0033] S10, forming a transfer layer on the base film, performing aluminum plating on the transfer layer to form an aluminum plating layer, and forming a glue layer on the aluminum plating layer.

[0034] Specifically, the transfer coating was prepared by weighing the raw materials of each component according to the above-mentioned parts by mass, the base film was put into the unwinding device, the transfer coating was coated by the coating roller, and the transfer layer was formed after drying in a five-section oven.

[0035] Optionally, the method for preparing the above-mentioned transfer coating in one embodiment includes the following steps S11-S13:

[0036] S11. Weigh each raw material according to the parts by mass.

[0037] S12. Put the solvent, cellulose resin, polyacrylic resin and polyaniline into the reactio...

Embodiment 1

[0045] Weigh each raw material according to the following parts by mass: 10 parts of cellulose resin, 8 parts of polyacrylic resin, 6 parts of polyaniline, 0.9 part of tin tetrachloride, 3 parts of tetraacicular zinc oxide whiskers, 0.2 part of polypyrrole, 0.3 part of sodium styrene sulfonate, 0.1 part of multilayer graphene, 0.5 part of defoamer (BYK-054), 0.5 part of leveling agent, 0.5 part of wetting agent, 0.5 part of cosolvent and 60 parts of n-propyl acetate. Put n-propyl acetate, cellulose resin, polyacrylic resin and polyaniline into the reaction kettle, heat the reaction kettle to 70°C, start the stirring device at 900rpm and stir for 1.5 hours. Then put the remaining raw materials into the reaction kettle, continue stirring at 500rpm for 1.5 hours, cool to 25°C and filter through a 300-mesh filter to obtain the transfer coating.

[0046] Put the base film into the unwinding device, apply the transfer coating through the coating roller, and form the transfer layer a...

Embodiment 2

[0048] The experimental procedure of Example 2 is basically the same as that of Example 1, except that the raw material does not include tetraacicular zinc oxide whiskers.

Abstract

The invention relates to transfer paper and a preparation method thereof. The transfer paper comprises a back coating layer, a body paper layer, a glue layer, an aluminum plating layer, a transfer layer and a varnish layer, wherein the transfer layer is prepared from a transfer coating; the transfer coating is mainly prepared from the following raw materials in parts by mass: 8-12 parts of cellulose resin, 6-10 parts of polyacrylic acid resin, 5-8 parts of polyaniline, 0.2-1.5 parts of stannic chloride, 0.5-4 parts of auxiliary agent and 55-65 parts of solvent. The transfer paper disclosed bythe invention has good anti-static electricity capacity, static electricity is unlikely to be accumulated on the transfer paper so as to eliminate a problem that the transfer paper layers are mutuallyadhered due to static electricity when being overlaid, so that the transfer paper layer can be easily separated during processing, paper damage scrap due to improper separation is avoided, productionefficiency is effectively improved, production cost is lowered, and a market application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a transfer paper and a preparation method thereof. Background technique [0002] At present, in the packaging industry, transfer paper is widely used in tobacco, wine, tea and cosmetics because of its good performance in terms of gloss, smoothness, flexibility, environmental protection, printing adaptability and beautiful anti-counterfeiting effects. Packaging of high-end goods, especially tobacco products. [0003] During the processing and transportation of transfer paper, it is often necessary to stack multiple sheets of transfer paper, but the general transfer paper is prone to electrostatic adhesion when stacked, and it needs to be carefully separated during subsequent processing or use, otherwise improper operation It is easy to cause the surface of the transfer paper to be damaged and scrapped, which greatly reduces the production efficiency and increases the production...
