Abstract

The invention relates to a colored hot-melting pre-coating film and a preparation method thereof. The colored hot-melting pre-coating film is prepared from the following materials in percentage by weight: 0.5 to 15 percent of pigment and / or organic toner, 1 to 15 percent of water-based spot color ink, 0.5 to 2 percent of styrene, 0.5 to 5 percent of crylic acid, 0.2 to 1 percent of isooctyl ester, 0.5 to 2 percent of hydroxyethyl acrylate, 2 to 10 percent of acrylic ester, 1 to 6 percent of acetic ether, 0.01 to 5 percent of ABO, 0.1 to 0.5 percent of ammonium persulfate, 1 to 5 percent of mixture of diacetone acrylamide and ADH, 0 to 3 percent of aziridine, 0.1 to 1.5 percent of mixture of tert-butyl hydroperoxide and formaldehyde hydrosulfite, 0.02 to 0.5 percent of oleic acid polyoxyethylene ester, 25 to 35 percent of EVA and 40 to 65 percent of BOPP or PET. The colored hot-melting pre-coating film and the preparation method thereof, provided by the invention have the advantages that the preparation process is simpler without needing films and a published printing laminating process, a printing laminating product superior to printing can be obtained, pollution is avoided, the production efficiency is high, the quality is good, the color is even and beautiful, and the lamination can be performed without needing an expensive printing process. The film obtained by preparation can be directly used for surface lamination of a paper product.

Description

[technical field] [0001] The invention relates to a colored hot-melt film, in particular to a colored hot-melt precoat film and a preparation method thereof. [Background technique] [0002] With the rapid development of printing technology, the application fields of lamination technology are becoming more and more extensive, and its post-press processing technology is also facing more and more technical challenges. Improving the performance and reducing cost of printing laminating adhesive has become the top priority of many domestic manufacturers. At present, the production technology of laminating adhesive is very mature, and its performance and cost are closely related, so it cannot be at the cost of reducing performance while reducing cost. At present, the lamination of domestic packaging and printing enterprises is still dominated by dry lamination. With the rapid development of the economy and the gradual maturity of various conditions, the printing and laminating pr...
