Problems solved by technology
Both of these lamination methods use adhesive hot pressing to compound solid BOPP / PET film, which consumes a lot of energy in production and processing, and the processing cost is high. Volatile organic solvents cause environmental pollution, and the cost of raw materials for these two lamination methods is relatively high, which brings certain economic pressure to the production enterprises

Embodiment 1
[0022] The cross-linked plasticized resin liquid consists of (weight %):
[0023]
[0024] Among the above raw materials: wherein the polyurethane resin liquid contains 22% C=C functional bond groups, the molecular weight is 3500, and the epoxy resin liquid has an epoxy value of 0.55 and a molecular weight of 8000.
[0025] The production method of the adhesive-free type paper printed matter lamination of the present invention is realized through the following steps:
[0026] Step 1: Ink printing is carried out on the printing surface of the paper, and the surface ink is completely dried;
[0027] Step 2: using the above-mentioned cross-linked plasticized resin solution;
[0028] Step 3: using a coating machine to coat the cross-linked plasticized resin solution on the surface of the paper print;
[0029] Step 4: Send the paper printed matter coated with the cross-linked plasticizing resin solution to the infrared drying device with a heating temperature of 150-180°C and ...

The invention relates to crosslinking plasticized resin liquid and a production method of a glue-free type paper-print composite film. The crosslinking plasticized resin liquid comprises the following materials in percent by weight: 30-40 percent of polyurethane resin liquid, 45-60 percent of epoxy resin liquid, 3-6 percent of benzophenone, 3-6 percent of 1-hydroxyl cyclohexyl phenyl ketone, 1-4 percent of diphenyl iodonium(diphenyliodonium) salt, 0.3-1.5 percent of siloxane auxiliary agent; the problems such as solvent volatization and environmental pollution in the processes of curing and plasticization are avoided; and after the materials are plasticized into a film, the film is completely attached to the surface of a paper print dispensing with other adhesives, the production process is simple and convenient, the efficiency is high and the processing cost is low.
Description
technical field [0001] The invention relates to the technical field of post-processing in the printing and packaging industry, in particular to a production method for laminating paper printed matter and a cross-linked plasticizing resin solution used therein. Background technique [0002] At present, most of the paper printing and packaging products in the printing and packaging industry are waterproof, moisture-proof, wear-resistant, and have high surface brightness. Toothpaste outer packaging boxes, food outer packaging boxes, books and periodicals, etc. There are currently two methods of laminating the surface of paper printed matter. One is to directly use BOPP / PET film to coat glue, and after drying, it is hot-pressed and bonded to the paper. The other is the pre-coated film composite method, that is, a special glue is coated on the BOPP / PET film and dried and then rolled up to form a BOPP / PET film with a dry adhesive on one side, that is, It is a BOPP / PET pre-coated ...
