The invention is applicable to the technical field of water transfer printing paper manufacturing, and discloses a top coating and a preparation method thereof as well as water transfer printing paperand a preparation method of the paper. The preparation method of the top coating comprises the following steps: performing mixing: mixing water and potato starch according to a mass ratio of (10:3) to (10:4) in a reaction kettle to obtain a potato starch mixed solution; performing heating and stirring: heating the potato starch mixed solution under stirring, and when the potato starch mixed solution is heated to a preset heating temperature, stopping heating; performing heat preservation: performing heat preservation on the heated potato starch mixed solution, and stopping stirring to obtaina pasty top coating; and performing cooling: cooling the pasty top coating to a preset cooling temperature to obtain the top coating. The top coating prepared by the method coats a bottom coating filmof water transfer printing paper to generate a top coating light film, the reaction time of the top coating light film can be controlled within 10-20 seconds after the water transfer printing paper is in contact with water, the demolding reaction time is shortened, and the transfer efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of water transfer printing paper production, in particular to a surface coating and a preparation method thereof, water transfer printing paper and a preparation method thereof. Background technique [0002] Water transfer printing paper mainly realizes the transfer of exquisite patterns to the transfer target object through draping transfer printing. As people's requirements for the accuracy of product packaging are getting higher and higher, the production and processing parties have higher requirements for the transfer efficiency of water transfer printing paper. Also getting higher and higher. [0003] At this stage, the pigment pattern on the water transfer printing paper circulating in the market generally has the characteristics of long release reaction time and low transfer efficiency during the transfer decal process. The applique workers need to wait for the water transfer paper and the pigment pat...
