Problems solved by technology

[0004] At present, there are also all-water-based colorful granite paints for interior and exterior walls on the market, but due to the simple physical coating used in its production, or the use of anion and cation external gel technology or colloidal polar substances and base paint gels (color particle surface The external gel technology of heterosexual metal ions) has a long gel reaction time (2-3 hours) and the color particles of the product are not stable enough, and it is easy to bleed and cross-color during storage, because the concentration of ions and the amount of addition will affect the color particles The lower the concentration of metal ions, the smaller the color particles, and the softer th...

Embodiment 2

[0023] The basic process of this example is the same as Example 1, the difference is that the color granite coating, including the dispersed phase, dispersion medium and suspoemulsion, has a weight ratio of 50:25:25.

[0024] The components and parts by weight of the dispersed phase are as follows:

[0025] 10 parts of deionized water, 2 parts of bentonite (half of magnesium aluminum silicate and half of hydrophilic organic bentonite), 60 parts of alkali-tackified waterborne polyurethane resin, 0.1 part of wetting agent, 0.5 part of dispersant, and 0.3 part of defoamer , 16 parts of fillers, 3 parts of ceramic pigments, 0.3 parts of anti-mold preservatives, 5 parts of film-forming aids, 0.8 parts of water-based isocyanate, and 2 parts of associative rheological agents.

[0026] The components and parts by weight of the dispersion medium are:

[0027] Bentonite solution (5% solution of magnesium aluminum silicate and half of hydrophilic organic bentonite) (percentage by weight...

Embodiment 3

[0031] The basic process of this example is the same as that of Example 1, the difference is that the weight ratio of the granite coating, including dispersed phase, dispersion medium and suspoemulsion, is 60:20:20.

[0032] The components and parts by weight of the dispersed phase are as follows:

[0033] 10 parts of deionized water, 2 parts of bentonite (half of lithium magnesium silicate and half of hydrophilic organic bentonite), 54 parts of alkali-tackified waterborne polyurethane resin, 0.2 part of wetting agent, 0.5 part of dispersant, and 0.3 part of defoamer , 20 parts of fillers, 5 parts of ceramic pigments, 0.2 parts of anti-mildew preservatives, 5 parts of film-forming aids, 0.8 parts of water-based isocyanate, and 2 parts of associative rheological agents.

[0034] The components and parts by weight of the dispersion medium are as follows:

[0035] Special bentonite solution (5% solution of lithium magnesium silicate and half of hydrophilic organic bentonite) (pe...

Abstract

Granite coating is disclosed. The granite coating comprises a dispersion phase, a dispersion medium and a suspension emulsion. The weight ratio of the dispersion phase, the dispersion medium and the suspension emulsion is 50-60:20-25:20-25. The dispersion phase comprises deionized water, bentonite, waterborne polyurethane resin tackified by an alkali, a wetting agent, a dispersing agent, a defoaming agent, a fuller, a ceramic pigment, a mildew-resistant antiseptic, a film coalescing aid, water-based isocyanate and an association type rheological agent. The dispersion medium comprises a bentonite solution and alkaline inorganic sol. The suspension emulsion comprises a PUA polyurethane dispersion or waterborne silicon resin, an association type rheological agent, a mildew-resistant antiseptic and deionized water. The high-solid-content exterior crosslinked type water-in-water granite coating is a high-solid-content fully-aqueous product adopting an interior and exterior crosslinking technique and is an environmentally-friendly decoration material having extremely good stability and a high spreading rate. The service lifetime of the granite coating can be more than 10 years. The granite coating is an idea substitute of marble, granite, rock sheet stone-like coating, and the like.

Description

technical field [0001] The invention relates to a coating, in particular to a granite coating. Background technique [0002] Natural granite is widely used in high-end exterior wall decoration projects because of its excellent durability, hard texture, rich texture, and good durability. After polishing, it is as bright as a mirror and has gorgeous and noble decorative and protective effects. However, as a brittle material, natural stone has poor material uniformity and large dispersion of bending strength. It is inevitable that some slight and difficult-to-find internal injuries will occur in the process of generation, mining and processing. Moreover, excessive mining will cause soil erosion, which is not conducive to the protection of the ecological environment. Although stone does not bear the load of the three-dimensional structure in the process of curtain wall, it must bear the influence of self-weight, wind, earthquake, temperature and other loads and effects, and the...
