Abstract

The invention relate to the technical field of transfer film preparation, in particular to a baking printing ink transfer film and a preparation method thereof. The baking printing ink transfer film sequentially comprises a base film layer, a release layer, a baking protection layer and a baking printing ink layer from top to bottom, wherein baking printing ink of the baking printing ink layer is prepared from the following components: 18%-20% of inorganic pigments, 0.5%-1% of a wetting agent, 40%-42% of polyester resin, 4%-5% of modified epoxy resin, 10%-13% of n-butyl ether amino resin, 3%-6% of benzol amino resin, 0.5%-1% of a flatting agent, 1.5%-2% of modified polyester resin, 4%-6% of closed polyisocyanate, 1%-2% of coupling agent, 2%-7% of normal propyl alcohol and 3%-10.5% of normal propyl acetate. The baking printing ink transfer film is prepared by sequentially coating the base film layer with a release material, a baking protection layer and a baking printing ink layer, and drying to obtain the baking printing ink transfer film. The baking printing ink transfer film can be directly transferred to tinplate or aluminum sheets, so as to solve defects that the printing definition of the tinplate and the aluminum sheets is poor, lots of materials are wasted, and the yield is low in the traditional process; the baking printing ink transfer film has the characteristics of high printing definition and material utilization rate, no waste and high yield.

Description

technical field [0001] The invention relates to the technical field of transfer film preparation, in particular to a baking ink transfer film and a preparation method thereof. Background technique [0002] At present, tinplate and aluminum sheets with colorful and changeable patterns are mainly printed by baking ink roll coating and offset printing. Existing problems are 1. The layout resolution of the roller coating itself is low, so the definition of the roller coating process itself is poor. 2. The offset printing method is because the pressure of the contact between the offset plate and the metal affects the transfer of the ink, and there are shortcomings such as incomplete transfer and ink dot deformation. 3. Traditional tinplate or aluminum sheet printing is directly printed on the metal sheet. When printing, the sheet needs to be moved to overlap each color, and each color must be adjusted to match the color of the sample. Generally, it takes half an hour to an hour....
