Preparation method of tensile and aging resistant transfer film

Abstract

The invention discloses a preparation method of a tensile and aging resistant transfer film, and belongs to the technical field of film processing. According to the preparation method of the tensile and aging resistant transfer film, epoxidized soybean oil and acrylate are subjected to a hydroxyl condensation dehydration reaction to form a network interpenetrating cross-linking structure, and theepoxidized soybean oil contains polar groups such as epoxy groups, ether bonds and hydroxyl groups, and active groups. The epoxidized soybean oil in an emulsion solution of a printing layer has high oxidation resistance, and can promote curing and cross-linking of polyester resin, and anti-aging modified rubber powder absorbs and utilizes ultraviolet rays. As a release layer, a surface active release agent belongs to a nonionic surfactant. The surface active release agent does not generate ions and can protect ink of the printing layer to make the ink be difficult to emulsify and oxidize, andabsorption of ultraviolet light by titanium dioxide is improved. The photocatalytic action of the titanium dioxide can also accelerate curing of the polyester resin in the transfer film, and weaken the aging effect of the ultraviolet light on the transfer film, thus the gloss of protected prints is bright and durable, and the preparation method has broad application prospects.

Description

technical field [0001] The invention discloses a preparation method of a stretch-resistant and aging-resistant transfer film, which belongs to the technical field of film processing. Background technique [0002] The transfer film is an intermediate carrier, which exists on the transfer paper base or plastic base, carries the printed or printed pattern, and is used to transfer to a layer of chemical elastic film on the printed article. Widely used in advertising, decoration, etc. [0003] At present, in order to achieve the functions of rich color, fineness, brilliance, durability, wear resistance and high temperature resistance of leather, it is generally necessary to print on the surface of leather. Due to the unevenness of leather products, transfer technology is generally used in the process of selecting printing. Leather The transfer film came into being. When in use, the leather transfer film is hot-bonded with artificial leather, PU leather and genuine leather by pre...
