Embodiment 1

[0026] Such as figure 1 Shown, a kind of production method of imitation solid wood thermal transfer film adopts thick 25 μ biaxially stretched polyester film (BOPET) matte film as carrier film 1, and adopts the double group of polyurethane resin and isocyanate to form on this carrier film Resin is used for local coating treatment to obtain partial treatment layer 2, and a solid wood pore pattern is formed on carrier film 1; then solid wood pore effect is formed after curing in an oven at 70°C for 36 hours, and then coating release layer 3 and protective layer 4 are released. The material of the type layer and the protective layer is acrylic resin, and then the pattern information layer 5 and the following layer 6 are printed, and the material of the following layer 6 is acrylic resin, and finally an imitation solid wood transfer film is formed.

Embodiment 2

[0028] A method for producing imitation solid wood thermal transfer film, the method comprising the following steps:

[0029] (1) A biaxially stretched polyester film (BOPET) bright film with a thickness of 15 μ is used as a carrier film, and a two-component resin of polyurethane and polyester is used for partial coating on the carrier film to obtain a partial treatment layer. A solid wood air hole pattern is formed on the film;

[0030] (2) The film obtained in step (1) is placed in a 60°C oven for curing, the curing time is 48 hours, and a solid wood pore pattern is formed on the carrier film;

[0031] (3) on the partial treatment layer of the film that step (2) obtains, coat release layer and protective layer successively, release layer is polyamide resin, and protective layer is polyester resin;

[0032] (4) Print the information layer graphic layer on one side of the protective layer, such as solid wood pattern;

[0033] (5) Coating an adhesive layer on the information ...

Embodiment 3

[0035] A method for producing imitation solid wood thermal transfer film, the method comprising the following steps:

[0036] (1) A biaxially stretched polyester film (BOPET) bright film with a thickness of 30 μ is used as the carrier film, and a two-component resin of vinyl acetate resin and acid ketone resin is used for partial coating on the carrier film to obtain a partial treatment layer , forming a solid wood pore pattern on the carrier film;

[0037] (2) Place the film obtained in step (1) in an oven at 80° C. for curing, and the curing time is 24 hours to form a solid wood pore pattern on the carrier film;

[0038] (3) on the partial treatment layer of the film that step (2) obtains, coat release layer and protective layer successively, release layer is vinyl chloride resin, and protective layer is polyurethane resin;

[0039] (4) Print the information layer graphic layer on one side of the protective layer, such as solid wood pattern;

[0040] (5) Coating an adhesiv...

Abstract

The invention relates to a production method of a heat transfer film imitating solid wood, comprising the following steps of: (1) partially processing a carrier film in a coating way by using bi-component resin so as to obtain a partial processing layer, and forming solid wood pore patterns on the carrier film; (2) placing the film obtained in the step (1) into a drying oven at 60 DEG C-80 DEG C for curing for 24-48 hours; (3) sequentially coating a releasing layer and a protecting layer on the partial processing layer of the film obtained in the step (2); (4) printing an information layer onone surface of the protecting layer; and (5) coating a bonding layer on the information layer so as to obtain the heat transfer film imitating the solid wood. Compared with the prior art, the invention has less production procedure, convenient production, good transferring effect, and the like.

Description

technical field [0001] The invention relates to a production method of a transfer printing film, in particular to a production method of a thermal transfer printing film imitating solid wood. Background technique [0002] Imitation solid wood transfer film is a thermal transfer film that imitates the pattern and pores of solid wood and has exactly the same pattern effect as solid wood, and then transfers the pattern pattern to the printing substrate (such as wood-plastic board, PVC board, PS board) to form a imitation solid wood decorative board with exactly the same effect as solid wood, which is widely used in furniture production and interior decoration instead of wood. At present, the existing wood grain transfer film, the carrier film used needs to be treated with corona on the surface before use, the production process is long, and the curing conditions generally need to be carried out at a high temperature of 80-150 ° C, which is easy to deform the carrier film , cau...
