Embodiment 1

[0017] The steps to make transfer glue are as follows:

[0018] 1) Mix alcohol and water in a ratio of 1:1, and stir evenly, as a diluent;

[0019] 2) mixing the resin emulsion and the organic heat-curable polymethylurea resin in a ratio of 1:0.005, and stirring evenly, as a transfer adhesive;

[0020] 3) Mix the diluent and the transfer glue in a ratio of 1:20, and stir evenly to prepare the transfer glue.

[0021] Anilox roll gluing method is used for coating, the coating pressure is 0.2mpa, the cold cylinder pressure is 0.3mpa, and the drying tunnel tension is 0.2mpa.

[0022] The speed of the coating machine was 90 m / min.

[0023] The oven temperature during coating was 80°C.

[0024] In this embodiment, the combination of resin emulsion and organic thermal curing polymethylurea resin is used, and a diluent is added to reduce the adhesive force of the transfer glue, enhance the peeling effect of the aluminum layer of the transfer product and protect the integrity of the...

Abstract

The invention relates to a preparation method of transfer glue used for coating and a coating method of the transfer glue. The preparation method is characterized by including the following steps: 1) mixing alcohol and water with a proportion of 1:1, stirring evenly and forming diluent; 2) mixing emulsion resin and organic heat curing poly methylurea resin with a proportion of 1: 0.005, stirring evenly and forming transfer glue adhesive; 3) mixing the diluent and the transfer glue with a proportion of 1:20, stirring evenly and obtaining the transfer glue. The coating method is characterized in that an anilox roller is adopted to feed the glue when coating is conducted, coating pressure is 0.2 MPa, pressure of a cooling cylinder is 0.3 MPa, and pressure of a drying tunnel is 0.2 MPa. The preparation method of the transfer glue used for the coating and the coating method of the transfer glue have the advantages that adhesive force of the transfer glue is poor, a peeling effect of an aluminum layer of transfer products is enhanced, integrity of patterns is protected, a phenomenon of silk drawing in the coating process is completely eradicated, and due to the fact that the way of feeding the glue through the anilox roller is adopted, the coating is even and easy to control.

Description

technical field [0001] The invention specifically relates to a method for preparing transfer glue for coating and a coating method thereof. Background technique [0002] The processing steps of the laser film are coating, transfer and slitting. The technicians found that wire drawing is easy to occur during the coating process, resulting in hair spots after coating. In the subsequent transfer process, the aluminum layer is difficult to peel off. The integrity of the pattern cannot be guaranteed when peeling off, and the reject rate is high. After research, technicians found that the transfer glue used in the coating process had too strong cohesive force. Contents of the invention [0003] The purpose of the present invention is to solve the defects that the transfer glue used in the laser film coating process of the prior art has too strong cohesive force, which causes adhesion and hair point phenomenon to occur easily after coating, and provides an A method of making tr...
