Embodiment 1

[0021] Embodiment 1 of a preparation method of a high elastic heat transfer film: a preparation method of a high elastic heat transfer film, the preparation steps are as follows

[0022] 1) Use 20μm biaxially oriented polypropylene film as the base film, hereinafter referred to as BOPP base film;

[0023] 2) Coating the surface of the BOPP base film to form an elastic color layer: mix 22% polyurethane resin, 77% methyl ethyl ketone, and 1% accelerator and stir evenly, then add 2% dye and continue stirring evenly to prepare elastic Color layer material, and then apply the above elastic color layer material to the surface of BOPP base film with a 50-mesh screen roller, react and dry in a four-stage oven to form an elastic color layer, in which the highest temperature is 90 °C, and the speed is 45m / min;

[0024] 3) Slitting and winding the elastic film with a slitting machine to obtain the high elastic heat transfer film.

Embodiment 2

[0025] Example 2 of a method for preparing a high-elastic heat transfer film: a method for preparing a high-elastic heat transfer film, the preparation steps are as follows

[0026] 1) A 25 μm biaxially oriented polypropylene film is used as the base film, hereinafter referred to as the BOPP base film;

[0027] 2) Coating the surface of the BOPP base film to form an elastic color layer: first mix 30% polyurethane resin, 68% methyl ethyl ketone, and 1.2% accelerator and stir evenly, then add 0.8% dye and continue stirring evenly to prepare Elastic color layer material, and then apply the above elastic color layer material to the surface of the BOPP base film with a 60-mesh screen roller, and react and dry in a four-stage oven to form an elastic color layer. 80m / min;

Abstract

The invention discloses a high-elasticity heat transfer membrane and a preparation method thereof. The high-elasticity heat transfer membrane comprises a BOPP (biaxially-oriented polypropylene) base membrane, wherein the BOPP base membrane is coated with an elastic color layer; the BOPP base membrane has high tensile strength, high toughness, excellent transparency, excellent printing characteristics and high strippability; the elastic color layer has a tensile property, and the color of the heat transfer membrane can be changed by adjusting ingredients of dye. The color layer can stretch with stretching of cloth after hot stamping, and the attractiveness of the elastic cloth is improved.

Description

technical field [0001] The invention relates to a thermal transfer film and a preparation method thereof. Background technique [0002] At present, heat transfer film is widely used in various industries, especially in the surface decoration industry of cloth. Due to the limitations of production technology and production equipment, when hot stamping elastic fabrics, the traditional thermal transfer film cannot meet its elastic requirements, and cannot be stretched with the stretching of the fabric, which will cause the color layer to break and cannot cover the fabric. surface. Contents of the invention [0003] The purpose of the present invention is to provide a high-elasticity thermal transfer film in order to solve the above-mentioned deficiencies in the prior art. After hot stamping, the color layer can be stretched along with the stretching of the cloth, so as to improve the aesthetics of the elastic cloth. [0004] A technical solution of the present invention is:...
