Embodiment 1

[0015] 1) Take 3kg of nitrocellulose resin, 3kg of cellulose acetate propionate resin, 4kg of cellulose acetate butyrate resin, 15kg of carboxy-modified acrylic resin and 1kg of blocked isocyanate resin, and take several kinds of resin for later use;

[0016] 2) Add 5kg of ethanol, 10kg of n-propanol, 25kg of ethyl acetate, 15kg of n-butyl acetate, and 10kg of propylene glycol methyl ether into the reaction kettle, heat it to 70°C, and keep the temperature constant, and put several resins that have been weighed into the reactor at one time. In the reactor;

[0017] 3) Turn on the stirring and control the stirring rate to 1000rpm, and continue to stir for 3 hours to dissolve all the resin in the reactor;

[0018] 4) After the resin is completely dissolved, put 0.5kg of slip agent, defoamer, and crosslinking agent into the reaction kettle, and continue to stir for 0.6h to disperse the additives evenly;

[0019] 5) Stop heating the reactor, continue stirring to cool the reaction...

Abstract

The invention provides a preparation method of a highly-stain-proof coating for wine box external packaging. Cellulosic resin and modified acrylic resin are used as a main body, a little amount of isocyanate resin is added in the main body, and the various kinds of resin are dissolved in an organic solvent and then added with an appropriate amount of additive to prepare a novel coating which can be used for wine box product external packaging. The stain-proof performance of the wine box external packaging coating is improved, the adhesion, printing adaptability and the like of the coating are improved, and the preparation method of the highly-stain-proof coating has the advantages of being simple in production procedures, easy to operate and low in cost, and has the extremely high popularization value in the wine box external packaging field.

Description

field of invention [0001] The invention relates to a coating for wine box outer packaging, in particular to a preparation method for a type of coating for wine box outer packaging that requires extremely high anti-fouling properties. Background technique [0002] Wine as a commodity appears on almost all shopping mall shelves, and the first thing that catches people's eyes on the dazzling array of wine shelves is often the outer packaging of wine—wine box. Wine box packaging plays a very important role in the sales of wine, especially its role in attracting consumers, increasing product added value, satisfying consumers' spiritual needs, and consolidating the brand and corporate image has become more and more recognized by people. At present, in the selection of wine box packaging materials, carton-style outer packaging still plays a dominant role. In carton packaging products, many use OPP film as the coating base material to be used together with paper, but this method no...
