Abstract

The invention relates to the technical field of coatings, in particular to a water-based crack paint as well as a preparation method and an application method thereof. The water-based crack paint comprises a water-based crack base paint and a water-based crack finish paint, wherein the water-based crack base paint comprises an aliphatic polyurethane dispersoid emulsion I, a defoamer, a substrate wetting agent, a thickener and water; and the water-based crack finish paint comprises an aliphatic polyurethane dispersoid emulsion II, high-TG (glass-transition temperature) acrylic acid resin, a defoamer, a substrate wetting agent, a thickener and water. A film can be formed by the specific high-TG acrylic acid resin and aliphatic polyurethane dispersoid emulsions without addition of a pigment, filler and a film-forming additive, so that the environment is protected; and after the water-based crack paint is applied, a beautiful and vivid crack decoration effect can be formed on the upper surface of a base material to be decorated and the base material can be protected and decorated.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based crack paint, a preparation method and an application method thereof. Background technique [0002] Crackle paint is a description of European decoration art and a portrait of classical decoration style. It is noble, romantic, and full of artistic charm; it can quickly and effectively produce cracks, and the crack texture is uniform, varied, patchwork, and very three-dimensional. It has rich patterns, some are vigorous and criss-crossing, and some are natural and lifelike like a magnificent picture of mountains, rivers and rivers. It has a unique artistic beauty and is a combination of classical art and modern decoration. [0003] In recent years, with the development of the national economy and the improvement of living standards, the style of architectural decoration is changing with each passing day. There are more and more varieties of materials used in decorati...
