Problems solved by technology

Because the dielectric coating in the prior art is oily, after use, the dyne value on the surface of the aluminum plating layer is unstable, resulting in low adhesion between the UV glue layer and the aluminum plating layer; The medium coating is mainly based on oily acrylic resin, therefore, the volatile organic compound (VOC) content of the film prepared by it is high, which does not meet the requirements of environmental protection
Therefore, it is necessary to further improve the existing dielectric coating formula, to overcome the low adhesion of the dielectric coating to the aluminum coating in the prior art and the high content of volatile organic compounds (VOC) in the finished product. defect

Abstract

The invention relates to an aqueous medium coating formula coated on a cold revolving membrane. The formula comprises the following components in percentage by weight: 10-18 percent of styrene monomer, 10-15 percent of acrylic monomer, 2-10 percent of butyl acrylate, 30-40 percent of water, 20-30 percent of alcohol, 0.1-0.2 percent of polydimethylsiloxane and 0.1-0.3 percent of carboxylate anion active agent. The preparation method includes the following two steps: firstly, according to the formula, sequentially adding the alcohol and the water to a stirring drum and stirring for 5-10min at the constant temperature of 25-30 DEG C; and secondly, according to the formula, adding the styrene monomer, the acrylic monomer, the butyl acrylate and the polydimethylsiloxane to the stirring drum and finally wholly stirring evenly for 10-15min. After use, the aqueous medium coating formula leads to high adherence degree between a UV glue layer and an aluminum coated layer, and the content of volatile organic compounds (VOC) in a finished thin membrane reaches the standard.

Description

technical field [0001] The invention relates to the technical field of coating formulations, in particular to an aqueous medium coating formulation applied to a cold transfer film and a configuration method thereof. Background technique [0002] When using cold transfer technology to transfer metal texture patterns, usually a printing machine is used to coat UV glue on the cold transfer film, and then irradiate with UV light to achieve the transfer of metal texture patterns. Generally, the UV glue and the aluminum layer cannot be completely adhered. Therefore, it is usually necessary to add a medium layer between the UV glue layer and the aluminum layer, and to increase the adhesion between the UV glue layer and the aluminum layer by coating the medium layer. In the prior art, the dielectric coating is mainly made of oily acrylic resin. In actual use, the dielectric coating has the following two defects. Because the dielectric coating in the prior art is oily, after use, th...
