preparation example Construction

[0028] The preparation method of the above-mentioned transfer coating according to one embodiment of the present invention includes the following steps S1-S3:

[0029] S1. Weigh each raw material according to the parts by mass.

[0030] S2. Put the solvent, cellulose resin, polyacrylic resin and polyaniline into the reaction kettle, and stir at 60° C. to 80° C. for 1 to 2 hours.

[0031] Specifically, the stirring speed is 800rpm-1000rpm.

[0032] S3. Put the remaining raw materials into the reaction kettle, continue to stir for 1-2 hours, and obtain the transfer coating after filtering.

[0033] Specifically, the stirring speed is 450rpm-600rpm, and a 300-mesh filter is used for filtration.

[0034] The preparation method of the above-mentioned transfer coating is simple in process and easy to realize. The obtained transfer coating is used to prepare the transfer layer of the transfer paper, which can reduce the accumulation of static electricity on the transfer paper, and ...

Embodiment 1

[0037] 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.

Embodiment 2

[0039] 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 a transfer coating and a preparation method thereof. The transfer coating is mainly prepared from the raw materials in parts by mass: 8 to 12 parts of cellulsic resin, 6 to 10parts of polyacrylic resin, 5 to 8 parts of polyaniline, 0.2 to 1.5 parts of stannic chloride, 0.5 to 4 parts of auxiliary agents and 55 to 65 parts of a solvent. The transfer coating provided by theinvention is used for preparing a transfer layer of transfer paper and can reduce accumulation of static electricity on the transfer paper, so that the problem that the transfer paper adheres to eachother because of static electricity when the transfer paper is stacked is solved; therefore, the transfer paper is easier to separate in a processing process, and meanwhile, paper surface damage andscrap caused by improper separation are also avoided; the production efficiency is effectively improved; the production cost is reduced; the market application prospect is broad.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a transfer coating 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 producti...
