Aqueous medium coating formula and preparation method thereof

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...
