Embodiment 1

[0041] Embodiment 1 of a preparation method for an anti-graffiti thermal transfer film for leather: a preparation method for an anti-graffiti thermal transfer film for leather, the preparation steps are as follows:

[0042] Step 1: Take the biaxially stretched polyester film as the base film, hereinafter referred to as the PET base film;

[0043] Step 2: Coating on the surface of the PET base film to form a release layer: mix cellulose acetate and organic solvent evenly to prepare a release layer material solution, and apply the material solution evenly on the PET base film through a 200-mesh anilox roller The surface is then reacted and dried in a five-stage oven to form a release layer. The temperature of each section of the oven is 80°C-100°C-130°C-130°C-90°C, and the speed of the machine is 80m / min. The temperature of each section of the above-mentioned oven can ensure the occurrence of curing reaction and the volatilization of organic solvents. Cooperating with the corres...

Embodiment 2

[0050] Embodiment 2 of a preparation method of an anti-graffiti thermal transfer film for leather: a preparation method of an anti-graffiti thermal transfer film for leather, the preparation steps are as follows:

[0051] Step 1: Take the biaxially stretched polyester film as the base film, hereinafter referred to as the PET base film;

[0052] Step 2: Coating on the surface of the PET base film to form a release layer: Mix cellulose acetate and an organic solvent evenly to prepare a release layer material solution, and evenly coat the material solution on the PET base film through a 250-mesh anilox roller The surface is then reacted and dried by a five-stage oven to form a release layer. The temperature of each section of the oven is 90°C-120°C-140°C-140°C-100°C, and the vehicle speed is 110m / min. The temperature of each section of the oven can ensure the occurrence of resin curing reaction and the volatilization of organic solvents. Cooperating with the corresponding vehicl...

Abstract

The invention discloses an anti-scrawling heat transfer film for leathers and a preparation method thereof. The anti-scrawling heat transfer film comprises a PET base film; and the PET base film is coated with a release layer, an anti-scrawling layer, a coloring layer, an aluminum plating layer and a back glue layer in sequence, wherein the anti-scrawling layer is formed by mixing and curing silicon auxiliaries and polyurethane resins, can enable scrawled printed objects to recover brightness and tidiness after wiping, has the leather texture and the toughness, and achieves the effect of protecting the coloring layer. The anti-scrawling heat transfer film is excellent in anti-scrawling effect, high in leather texture, excellent in toughness, high in brightness, bright in color and excellent in friction and solvent resistance.

Description

technical field [0001] The invention relates to a thermal transfer film and a preparation method thereof. Background technique [0002] In recent years, thermal transfer film has been widely used in the surface decoration of many materials due to its excellent performance, such as: cloth, paper, plastic products and leather and other materials. However, the traditional leather heat transfer film is not easy to clean after being polluted when applied to the leather substrate, and has poor abrasion resistance and solvent resistance. Contents of the invention [0003] The object of the present invention is: in order to solve the above-mentioned deficiencies in the prior art, provide an anti-graffiti effect for leather with good anti-graffiti effect, strong leather feeling, good toughness, high brightness, bright color, good abrasion resistance and solvent resistance. Thermal transfer film and its preparation method. [0004] A technical scheme of the present invention is: a...
