Abstract

The invention relates to a water-in-water faux marble paint and a preparation method thereof and belongs to the field of paint preparation. The paint is prepared by blending the following components in parts by weight: 150 to 200 parts of a protection glue solution, 150 to 200 parts of colored paint and 250 to 300 parts of a mixed emulsion. The water-in-water faux marble paint adopts a simple preparation process and is low in cost; after the water-in-water faux marble paint is sprayed, a coating has a vivid faux marble effect; the water-in-water faux marble paint overcomes the defect of poor decoration of a common paint, adopts a simple construction process and can be sprayed up at a time by using a spraying gun after the components are mixed.

Description

technical field [0001] The invention belongs to the field of paint preparation, in particular to a water-in-water imitation marble paint and a preparation method thereof. Background technique [0002] In recent years, architectural coatings are dominated by latex paints, which occupy the vast majority of the market share. The decorative effect of traditional architectural coatings makes people feel aesthetically tired, which affects the application of architectural coatings to a large extent. Thereby, people hope to have the appearance of new architectural decoration coating. [0003] Water-in-water imitation marble paint is mainly used for exterior walls. The emulsion is usually elastic emulsion, mainly polybutylacrylate emulsion. The polybutylacrylate elastic microspheres in the emulsion have excellent elasticity and are used as stress concentrates in the paint. , can not only induce crazes and shear bands to absorb energy, but also terminate crazes, but its dimensional s...
