Matte water-based transfer coating and preparation method thereof

Abstract

The invention provides a matte water-based transfer paint and a preparation method thereof. The paint comprises the following components in parts by weight: 5-25 parts of water-based polyurethane resin, 0.2-2 parts of dispersing aid, 1-7 parts of water-based matte resin, 66-94 parts of water and 0.05-1 part of aid. Compared with the prior art, the paint avoids using matting powder, and is a water-based transfer matte paint solution capable of implementing matte effects without using matting powder. The matte water-based transfer paint has excellent storage stability and coating leveling effects. The matte water-based transfer paint completely adopts the water-based resin system, is free of any volatile organic compound, is an environment-friendly paint in deed, and implements zero volatile organic compound.

Description

technical field [0001] The invention relates to a matte water-based transfer coating and a preparation method thereof. Background technique [0002] Modern packaging is increasingly pursuing individualization. Among them, aluminum foil packaging with a matte effect is more and more popular in the market due to its high-end and atmospheric visual perception, and is more and more applied to some relatively high-end tobacco, wine, cosmetics, food Waiting for packing. Most of this kind of packaging adopts the aluminum foil back-mounting process to combine aluminum foil with paper or film and other substrates through adhesives, so that the matte visual perception of aluminum foil can be directly displayed on the outside of the packaging. However, this process of aluminum foil consumes a lot of money, is costly, and cannot be degraded. It does not conform to the general trend of modern packaging and environmental protection. It is gradually replaced by the more cost-effective tra...

Problems solved by technology

However, this process of aluminum foil consumes a lot of money, is costly, and cannot be degraded. It does not conform to the general trend of modern packaging and environmental protection. It is gradually replaced by the more cost-effective transfer aluminum plating process, that is, the matte transfer aluminum plating film is used. Package

[0003] The current mainstream process of transfer coatings for matte transfer aluminized films is to achieve a matte effect by adding matting powder (such as matting wax, silica powder, etc.) to the transfer coating. The poor compatibility of the polymer resin in the polymer resin is prone to stratification, and it cannot be stored for a long time. CN 102367348 A is the above situation

Although the prior application CN 103360934 A discloses a water-based matte silver transfer coating and its preparation method, it uses fumed alumina, alcohol and water to mix to obtain a matte paste, and in essence it uses an additional matting substance that is incompatible with the resin. Obtain matte effect, can not fundamentally solve the long-term storage problem; Although CN 105462471 A discloses a kind of self-extinction water-based transfer aluminized paint, still rely on two kinds of poor compatibility resin (water-based polyurethane emulsion B and water-based polyurethane modified acrylic acid) to obtain a matte effect, although its long-term storage stability will be improved compared with CN 102367348 A and CN 103360934 A, it still cannot meet the long-term stable storage requirements of more than 6 months
