Problems solved by technology

[0004] 1) The aging resistance is poor, the holding force is low, and the peel strength gradually decreases during the placement process;
[0005] 2) Poor wettability to plastic films with low surface energy;
[0006] 3) The compatibility with printing ink is not good, and the ink transfer is not complete when peeling off;
[0007] 4) The drying speed is slow and cannot be coated at high speed;
[0008] 5) Laminated film products are prone to blistering and bursting during the indentation and concave-convex processes
However, most systems require two-component storage, which is inconvenient to use

Abstract

The invention discloses single component self-cross linking emulsion tackiness agent used for dry type compound and the preparation method thereof. The invention has the preparation method as follows: firstly, part of aqueous medium, part of emulsifying agent, and part of initiating agent and baking soda are measured and added in a reactor, and are warmed up 70 to 85 DEG C; secondly, then hard monomer, soft monomer, (methyl) acrylic acid and cross linking monomer are mixed, and form pre-emulsion together with part of the emulsifying agent and water; thirdly, 1 / 10 pre-emulsion is added firstly to form assistant emulsion by reacting, and then the pre-emulsion and initiating agent aqueous solution are added synchronistically to perform reaction, the time lasts for 3 to 5 hours. The water emulsion tackiness agent obtained has good stability, and is free from poison and dissolving agent, and is favor of good health of a worker and environmental protection. A compound produced product obtained by utilizing the emulsion tackiness agent of the invention has the advantages that the ageing resistance is excellent, the viscous force is high, and the foaming is not existent during the impressing and sagging process, and the invention has wide application market.

Description

Technical field: [0001] The invention belongs to the technical field of adhesives, and more specifically relates to a single-component self-crosslinking emulsion adhesive for dry lamination and a preparation method thereof. Background technique [0002] The dry laminating method is currently the most commonly used laminating method in China. It is to coat a layer of adhesive on the plastic film, and then evaporate the solvent or water in the adhesive through the drying tunnel of the laminating machine to dry, and then dry it. It is bonded with paper printed matter under hot pressing to form a laminated film product. The printed matter after lamination has a smoother and brighter surface due to the addition of a thin and transparent plastic film on the surface, which not only improves the gloss and fastness of the printed matter, but also prolongs the service life of the printed matter. Antifouling, abrasion resistance, folding resistance, chemical corrosion resistance and o...
