Embodiment 1

[0027] Embodiment 1 of a preparation method of a smooth elastic heat transfer film: a preparation method of a smooth elastic heat transfer film, the preparation steps are as follows

[0028] 1) Biaxially oriented polypropylene film is used as the base film, hereinafter referred to as BOPP base film;

[0029] 2) Coating on the surface of BOPP base film to form a smooth layer: mix 15% polyurethane resin and 80% methyl ethyl ketone, stir evenly at a speed of 900r / min, then add 5% organic silicone oil, continue stirring evenly to make Form a smooth layer of material liquid. Inject the smooth layer feed liquid into the trough, then use the 150-mesh anilox roll to strip the feed liquid, scrape the feed liquid evenly with a scraper, and coat the feed liquid evenly on the surface of the biaxially stretched polypropylene film, and then After 4 stages of oven reaction and drying, a smooth layer is formed; wherein, the addition of silicone oil within this concentration range can make th...

Embodiment 2

[0032] Example 2 of a preparation method of a smooth elastic heat transfer film: a preparation method of a smooth elastic heat transfer film, the preparation steps are as follows

[0033] 1) Biaxially oriented polypropylene film is used as the base film, hereinafter referred to as BOPP base film;

[0034] 2) Coating on the surface of the BOPP base film to form a smooth layer: mix 20% polyurethane resin, 40% methyl ethyl ketone and 30% nitrogen nitrogen-dimethylformamide, stir evenly at a speed of 1000r / min, Then add 10% organic silicon oil, and continue to stir evenly to make a smooth layer material liquid. Inject the smooth layer feed liquid into the trough, then take the material with a 200-mesh anilox roller, scrape the feed liquid evenly with a scraper, and coat the feed liquid evenly on the surface of the biaxially stretched polypropylene film, and then After 5 stages of oven reaction and drying, a smooth layer is formed; wherein, the addition of silicone oil within this...

Abstract

The invention discloses a smooth and elastic heat transfer film and a manufacturing method thereof. The smooth and elastic heat transfer film comprises a BOPP base film. The BOPP base film is sequentially coated with a smooth layer and an elastic layer. The thickness of the BOPP base film ranges from 20 microns to 25 microns. The BOPP base film with the thickness has high tensile strength, high toughness and dye wettability which are suitable for printing. Due to the smooth layer, the surface of the heat transfer film can be smooth after the heat transfer film is subjected to hot stamping, scraping resistance and wiping resistance are obviously improved, in addition, the smooth layer has the stripping performance, and the elastic layer can be separated from the BOPP base film; and due to the elastic layer, the heat transfer film can have different colors and also have elastic force and stretchability. After hot stamping and heat transfer are conducted, an elastic fabric surface layer can be smooth and resistant to scraping and wiping, a color layer is continuous, the attractiveness and the comfort level of fabric are improved, and the service life of the fabric is prolonged.

Description

technical field [0001] The invention relates to a thermal transfer film and a preparation method thereof. Background technique [0002] With the continuous development of light industry packaging technology, people's requirements for surface decoration materials have also increased. Due to the advantages of exquisite hot stamping patterns and convenient processing, heat transfer film occupies an increasingly important position in the surface decoration industry of fabrics. However, when the traditional heat transfer film is applied to elastic fabrics, there will be defects such as broken color layer, rough surface, poor scratch resistance and wear resistance, which will affect the aesthetics, comfort and service life of the fabric. 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 a kind of smooth elastic heat transfer film, after hot stamping and heat transfer, make the ...
