Abstract

The invention relates to the technical field of heat transfer films, and specifically relates to a high elasticity silicone rubber heat transfer film and a preparation method thereof. The high elasticity silicone rubber heat transfer film comprises following components from bottom to top: a bearing base material, a release layer, a silicone rubber surface layer, an interface bonding agent layer, and a TPU hot melt adhesive membrane; wherein the interface bonding agent layer is prepared an interface bonding agent, which comprises two resin components. The provided heat transfer film has the advantages of silicone rubber and TPU, such as excellent elasticity, high tearing resistant strength, weatherability, yellowing resistance, washing resistance, and the like. Layering is difficult to happen. Even if the heat transfer film is exposed under the sun, color change or fading is difficult to happen. The water washing fading rate is not more than 0.5%. When the color transfer film is washedwith materials with other colors, other materials will not be dyed easily. The stability is high. The heat transfer film can be easily adhered on multiple materials, the bonding strength is strong, the heat transfer film is not easy to peel off, the stability is good, the hand feeling is fine, the appearance is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of thermal transfer lettering film, in particular to a highly elastic silicone rubber lettering film and a preparation method thereof. Background technique [0002] Thermal transfer lettering film is a newer process for making patterns or LOGOs on cloth or textiles than screen printing. Most of the lettering films sold on the market are lettering films made of TPU material. The process is to first coat the back of the biaxially stretched polyester film with a 200-line anilox roller to coat the back coating liquid of the protective layer, and then further Oven drying; then apply a release agent on the front of the biaxially oriented polyester film with a comma scraper, and dry in the oven; then apply the color layer TPU ink to the release layer of the biaxially oriented polyester film with a comma scraper On the surface, enter the oven to dry the solvent in the ink; then use the hot-melt die head gap extrusi...
