Description
Technical Field
The invention relates to a preparation method of an inorganic modified water-based environment-friendly interior wall coating.
Background
The first generation of inorganic paint is a two-component paint composed of powder composed of inorganic pigment and filler and potassium silicate liquid, and is only applicable to the surface coating of a firm and absorptive mineral substrate, and is inconvenient to construct. The second generation is a single-component coating prepared by using potassium silicate as a main binder and an organic emulsion base material (less than 5 percent) as an auxiliary material and adding a proper amount of inorganic pigment, filler and multifunctional auxiliary agent, but is not suitable for the surface of an organic coating. Silica sol silicate coatings based on potassium silicate and silica sol as the main inorganic binders have been developed today. Today's inorganic coatings, which are effective in reducing cure shrinkage stress, are suitable for most building substrates, including robust organic coating surfaces, and are useful for wood surfaces and tropical rain forest climates.
Although a great improvement over previous systems, many drawbacks still exist with inorganic coating technology. The storage property, water resistance, scrub resistance and the like are more prominent. On one hand, the inorganic coating in the current market generally has the problems of unstable storage and incapability of effectively controlling viscosity, and the phenomenon of continuous rise of viscosity occurs; more systems can not pass the national relevant detection standards, particularly the detection of the heat storage stability, the viscosity can rise by more than sixty KU after being stored for 15 days at 50 ℃, and the stirring can not be uniform at the later stage, thereby greatly influencing the normal production, storage and use. On the other hand, the product quality of inorganic resins, emulsions and some related auxiliaries, which are core materials used in inorganic coating systems, is uneven, so that the water resistance and scrub resistance of the produced inorganic coatings are also greatly different. After a paint film is dried for 7 days at normal temperature, the related tests of water resistance and scrubbing resistance are carried out, the phenomenon of coating surface powder falling can occur when the inorganic paint with poor quality is soaked in water for 1 day, and the phenomenon of bottom exposure can occur when the paint film is scrubbed for about 600 times; the inorganic coating with relatively good quality can generate the phenomenon of coating surface powder falling after being soaked in water for 10 days, and can generate the phenomenon of bottom exposure after being scrubbed for about 4500 times, so that the inorganic coating can not reach the relevant national standard, and the quality problem can be generated at the later stage when the inorganic coating is forcibly used.
