Description

Environment-friendly coating for buildings
Technical Field
The invention relates to a coating, in particular to an environment-friendly coating for buildings.
Background
With the continuous improvement of the living standard of material culture, people are more and more exquisite in living environment and must carry out indoor decoration before moving; for wall decoration, the coating is mainly used for decoration, high-grade decoration is wall paper or soft cloth package, and the two have the advantages and disadvantages: for paint decoration, the paint has the advantages of continuous film coating, rich colors, good protectiveness and single decorative effect, has no luxurious three-dimensional texture and is relatively common; the wallpaper or soft cloth bag is noble and elegant, rich in color and strong in stereoscopic impression, and has the defects of splicing seams, easy falling off due to moisture, difficult maintenance and high price.
The paint industry has been developed in recent industries, but the paint itself has a long history. China is a world in which natural resin is used as a film-forming substance and is commonly called a lacquer. Early painters used mineral pigments, which may be referred to as the earliest waterborne paints, formulated with aqueous suspensions, or albumin. In the middle of the 19 th century, it was really understood how to dissolve solid natural resins with solvents to produce quick-drying coatings. In this sense, water-based coatings have a much longer history of use than solvent-based coatings. The simplest aqueous paints are lime emulsions, and the earliest latex paints were modified by adding emulsified linseed oil to lime emulsions, perhaps about a hundred years ago.
The stone-like paint is a kind of building paint with decorative effect similar to marble and granite, and has unique appearance and excellent performance. The main formula of the existing stone-like paint comprises the following components: emulsion: mainly plays a role in binding and film forming, such as pure acrylic emulsion or acrylate polymerized emulsion. Film-forming auxiliary agent: typically organic solvents such as alcohol ester-12, ethylene glycol. Aggregate, so that the stone-like paint can achieve the stone-like effect, such as natural mica powder or artificial sand. Other auxiliary agents: such as thickeners, preservatives and the like.
The stone-like paint in the prior art is easy to form color difference, cracks and hollows in the interior and the like after construction, and particularly in the construction of large-plane walls, the color difference is easy to form, so that the attractiveness of the outer wall surface is influenced; the defects of cracks, hollowing and the like are formed inside the paint, so that the paint layer is easy to fall off, the service life of the paint surface is shortened, the paint surface cannot be matched with the service life of a building, and the requirements of an owner cannot be met; moreover, the whole construction method is relatively complicated and inconvenient to operate.
