Embodiment 1～5
[0028] A kind of anti-stick flower water transfer coating described in embodiment 1~5, its preparation method is as follows:
[0029] Weigh according to the parts by weight in each example in Table 1, put the water-based polyurethane resin, water-based silicone acrylic resin, and water-based vinyl acetate resin in the reaction kettle and stir evenly, the stirring speed is 100-200rpm, and the stirring time is 5-10min ;
[0030] Add the film-forming aid and deionized water premix into the reaction kettle under stirring state, stir evenly, the stirring speed is 100-200rpm, and the stirring time is 10-15min;
[0031] Increase the stirring speed to 300-500rpm, then add the leveling agent, anti-scratch agent, and defoamer into the reaction kettle in sequence, stir evenly, and stir for 20-30 minutes.
[0032] After stirring evenly, use a 300-mesh filter to filter and pack.

Abstract
The invention provides an anti-flower sticking water-based transfer coating and a preparation method thereof. The coating comprises the following components in parts by weight: 10-25 parts of water-based polyurethane resin, 5-10 parts of water-based silicone acrylic resin, 1-5 parts of water-based vinyl chloride-vinyl acetate resin, 60-84 parts of deionized water, 0.5-5 parts of film forming assistant and 0.05-1 part of other assistants. The water-based transfer coating prepared by the preparation method provided by the invention overcomes the problem of easy flower sticking of a general water-based transfer coating in summer and autumn, the service performance of the water-based transfer coating is increased, and the range of application is widened.
Description
technical field [0001] The invention relates to an anti-stiction water-based transfer coating and a preparation method thereof, in particular to an anti-stiction vacuum aluminized transfer coating with excellent temperature resistance and solvent resistance and a preparation method thereof. Background technique [0002] Vacuum aluminized transfer coating (hereinafter referred to as "transfer coating") has been widely used in the packaging industry, especially the cigarette packaging industry, and has gradually penetrated into the packaging of high-end food and daily necessities such as chocolate packaging and cosmetic packaging. At present, the vast majority of transfer coatings used in the market are solvent-based systems, using a large number of ester ketone solvents such as ethyl acetate, butyl acetate, butanone, and some even use toxic organic solvents such as toluene and xylene. , has caused serious pollution to the production and use environment, and also endangered th...
