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 easy to stick to each other when stacked, and it needs to be carefully separated during subsequent processing or use, otherwise improper operation will easily lead to The surface of the transfer paper is damaged and scrapped, which greatly reduces the production efficiency and increases the production cost

preparation example Construction

[0031] The method for preparing the above-mentioned transfer paper according to an embodiment of the present invention includes the following steps S10-S30:

[0032] 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.

[0033] S20, forming a back coating on one side of the base paper, and then attaching the side of the base paper away from the back coating to the glue layer.

[0034] Specifically, the paper back-coating emulsion is prepared by weighing each component raw material according to the above-mentioned parts by mass, putting the base film into the unwinding device, coating the paper back-coating emulsion through the coating roller, and forming the back coating after drying in a three-section oven. Pass the compound roller directly without winding to make the emulsion-coated side of the uncoated paper stick to the undried glue layer,...

Embodiment 1

[0043] The raw materials were weighed according to the following parts by mass: 12.6 parts of water, 13.98 parts of acrylic emulsion, 2.1 parts of wax emulsion, 1.8 parts of γ-polyglutamic acid, 0.9 parts of sodium alginate, 0.9 parts of calcium chloride, and 1.2 parts of ketone removal additive , 0.5 parts of silk fibroin, 0.5 parts of cattail fiber, 0.3 parts of molybdenum disulfide, 0.2 parts of cellulose ether, 0.2 parts of starch ether, 0.03 parts of defoamer, 0.03 parts of preservative and 0.06 parts of leveling agent (BYK-331) share. Put water, wax emulsion, ketone-removing additives and additives into the reactor, heat the reactor to 55°C, start the stirring device at 1000rpm and stir for 0.5 hours. Then remaining raw material is dropped into reaction kettle, 800rpm continues to stir 1.5 hours, adopts 200 order filter screens to filter after cooling and obtain paper back coating emulsion.

[0044] Put the base film into the unwinding device, apply the transfer coating...

Embodiment 2

[0046] The experimental procedure of Example 2 is basically the same as that of Example 1, except that the raw materials do not include silk fibroin and cattail fibers.

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 back coating layer is prepared from paper back coating emulsion; the paper back coating emulsion is mainly prepared from the following raw materials in parts by mass: 10-14 parts of water, 12-16 parts of acrylic emulsion, 1-4 parts of wax emulsion, 1-4 parts of gamma-polyglutamic acid, 0.5-1.5 parts of sodium alginate, 0.5-1 part of calcium chloride, 0.5-2 partsof ketone removal additive and 0.03-0.2 part of accessory ingredient. The transfer paper has good water retaining capacity and water absorptivity, the moisture of the body paper is prevented from permeating, meanwhile, moisture cohered to a surface in the environment is absorbed so as to eliminate a problem that the transfer paper layers are mutually adhered when being overlaid, so that the transfer paper layer can be easily separated during subsequent processing, damage scrap due to improper separation is avoided, production efficiency is effectively improved, production cost is lowered, anda 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] With the fierce competition in the market and the continuous improvement of consumers' taste, the packaging industry is also facing great challenges. In recent years, the packaging and printing industry has developed in the direction of energy conservation and environmental protection along with the market, and transfer paper is one of them. The transfer paper is transformed from the original composite paper, and has strong market adaptability in terms of printing technology and environmental protection. At present, transfer paper is widely used in the packaging of high-end commodities such as tobacco, wine, tea and cosmetics, especially tobacco products, because of its good performance in terms of gloss, smoothness, flexibility, environmental protection, and printing adaptability. package of. ...
