Abstract
The invention relates to the technical field of printing information coating, in particular to a folding resistant paint and a preparation method thereof. The folding resistant paint is prepared from the following raw materials in percentage by weight: 75%-95% of waterborne polyurethane resin, 4%-25% of a diluent and 0.0002%-0.0005% of a flatting agent. Compared with the prior art, the folding resistant paint provided by the invention has high folding resistance and relatively good tensile resistance; the printing adaptability is not lower than that of existing coating resin on the market; and the folding resistant paint is free of the phenomena of reverse drawing, ink dropping and the like in the printing process. The invention further provides an application of the folding resistant paint to a packing box. The folding resistant paint with high folding resistance and relatively good tensile resistance is adopted by the packing box, so that the folding resistant paint is especially suitable for packing boxes, such as a cigarette packet packing box and a 350g gray-background white cardboard, with relatively large backing paper thickness. Therefore, the packing box employing the folding resistant paint can have relatively good texture and unique and novel design.
