Scrape-prevention heat transfer film and preparation method thereof

Abstract

The invention discloses a method for preparing a scrape-prevention heat transfer film. The method comprises the following steps of: (1) substrate preparation, wherein a substrate can be stickness-resistance release paper which can be recycled and reused or a polar material with a plastic laminating film on the surface; (2) gluing: printing hot-melting glue on the surface of the release paper or the polar material to form a hot-melting glue layer; (3) priming paint and golden oil applying: printing or jet-printing priming paint, and adding golden oil for mutual blending on the surface of the hot-melting glue layer; (4) color ink layer preparation, wherein a color ink layer is provided with various patterns, colors, decorative lines or trademarks; (5) scrape-prevention layer preparation: printing or jet-printing a scrape-prevention layer on the surface of the color ink layer and heating and drying with ultraviolet rays at high temperature; and (6) protective film covering: attaching a protective film on the surface of the scrape-prevention layer in a pseudo way, and stripping the protective film off a product after heat transfer. A scrape-prevention heat transfer film prepared with the method disclosed in the invention has high hardness and scrape-prevention effect and has a wear-resisting surface. The invention also discloses a scrape-prevention heat transfer film prepared with the method disclosed in the invention.

Description

technical field [0001] The present invention relates to a transfer printing film and its production method improved by breaking through the thermal transfer printing process technology, especially to a transfer printing pattern, texture or LOGO on an object after being subjected to high temperature and hot pressing, without the need for a second printing process. The processing of UV (ultraviolet) irradiation, or the painting and baking processing will have high hardness and wear-resistant surface, and the anti-scratch hot soft printing film with anti-scratch effect and its manufacturing method. Background technique [0002] Generally speaking, various patterns, patterns and logos are often printed on the surface of various shells, building materials, leather, wood or plastic products, etc., and are matched with colors to highlight the texture, beauty and quality of the product. effect. In order to achieve the above effects, the most traditional construction method is bakin...

AI Technical Summary

Problems solved by technology

[0010] Although the construction method of the aforementioned heat transfer film is very convenient and low in cost (about 1 / 3 of the cost of baking paint), the scratch resistance of the surface is very weak. When the heat transfer film is attached to the product, the base film It will be peeled off from the thermal transfer film, so that the release gold oil layer is the outermost layer to protect the color ink layer, but the hardness of the release gold oil layer is poor (less than 1H), so the wear resistance is not good, mainly because of the low density The high-density release gold oil has good ink adhesion ability. If high-density release gold oil is used, the ink adhesion ability will be reduced, and it may even peel off or be difficult to adhere. Therefore, in order to make the color ink have high adhesion Focus on using low-density release gold oil as the protective layer of color ink, but its main disadvantages are low hardness and poor wear resistance, and the surface is easy to scratch
