Problems solved by technology

[0003] At present, although there are many imitation solid wood furniture and panel products on the market, most of the surface wood grain patterns are presented by pasting solid veneer or using artificial PVC film, and all of them are It has certain defects: the former is prone to warped skin, which affects the service life; the latter has the shape of wood grain, but it is difficult to present the texture of wood grain, and the degree of simulation is poor.
The traditional wood thorn transfer film can simulate the three-dimensional effect of wood grain, but the wood thorn mold needs to be made by long-term curing or UV curing, and the operation is complicated

Embodiment 1

[0027] like figure 1 As shown, a concave-convex handle process transfer film is composed of a PET base film 2, a back coating 1 coated on one side of the PET base film 2, and a release film coated on the other side of the PET base film 2 from the inside to the outside. Layer 3, hard layer 4, wood grain pattern layer 5, base color layer 6 and glue layer 7 are composed; the wood grain pattern layer is made of the following raw materials by weight percentage: color layer ink 85%, microcapsule foaming agent 15% %.

[0028] The weight composition of each raw material of the microcapsule foaming agent is: 67 parts of EVA resin, 300 parts of toluene, 33 parts of sodium bicarbonate, and 500 parts of anti-solvent (butanone); wherein, the VA content of the EVA resin is 25 wt%. The microcapsule foaming agent is obtained by the following method: heat-dissolve EVA resin in toluene, add sodium bicarbonate when the temperature drops below 40 degrees, disperse for 2 hours using a high-speed...

Embodiment 2

[0037] A concave-convex handle process transfer film, the difference from Example 1 is that the wood grain pattern layer is made of the following raw materials in weight percentage: 80% of color layer ink, and 20% of microcapsule foaming agent. The weight composition of each raw material of the microcapsule foaming agent is: 70 parts of EVA resin, 320 parts of toluene, 30 parts of sodium bicarbonate, and 550 parts of anti-solvent (absolute ethanol); wherein, the VA content of the EVA resin is 32wt%. Others are with embodiment 1.

[0038] The preparation method of the microcapsule foaming agent and the production method of the concave-convex handle process transfer film refer to Example 1.

Embodiment 3

[0040] A concave-convex handle process transfer film, the difference from Example 1 is that the wood grain pattern layer is made of the following raw materials in weight percentage: 90% of color layer ink, and 10% of microcapsule foaming agent. Each raw material weight of described microcapsule whipping agent consists of: 75 parts of EVA resin, 300 parts of toluene, 25 parts of sodium bicarbonate, anti-solvent (by volume ratio 1:1 by butanone, dehydrated alcohol and Virahol: 1 mixed) 480 parts; wherein, the EVA resin VA content is 35wt%. Others are with embodiment 1.

[0041] The preparation method of the microcapsule foaming agent and the production method of the concave-convex handle process transfer film refer to Example 1.

Abstract

The invention relates to a technology transfer film with an unsmooth hand feeling. The film is composed of a PET base film, a back coating, which is painted on one surface of the PET base film, a release layer, a hard layer, a wood-grain pattern layer, a background color layer, and a glue layer, wherein the release layer, the hard layer, the wood-grain pattern layer, the background color layer and the glue layer are painted on the other side of the PET base film in sequence, and the wood-grain pattern layer is composed of the following raw materials in percentage by weight: 80 to 90% of color layer printing ink, and 10% to 20% of microcapsule foaming agent. The transfer film is characterized in that a wood-grain pattern layer containing a microcapsule foaming agent is added. During the painting and drying process, sodium bicarbonate in the microcapsule foaming agent is decomposed and foam is generated, so wood-grain patterns with a mimetic unsmooth wood-touch hand feeling will be printed on the PET base film, the stereo perception is very strong, the wood resources are saved, the product class is lifted, and the transfer film has a very high market promotion value.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a thermal transfer film capable of printing a real hand-touched concave-convex feeling of solid wood and a manufacturing method thereof. Background technique [0002] Solid wood furniture often sees people with its natural wood color, which naturally reveals a simple and calm beauty, which meets the psychological needs of modern urbanites advocating nature, so it will last forever. However, under the high price pressure of solid wood furniture, many consumers are discouraged and turn their attention to imitation solid wood furniture. [0003] At present, although there are many imitation solid wood furniture and board products on the market, most of the surface wood grain patterns are presented by pasting solid wood veneer or using simulated PVC film, and all have certain defects: the former is prone to warping, which affects the service life The latter has the shap...
