一种高固含纳米水性色浆及其制备方法
By preparing high-solids-content nano-aqueous pigments, an electrostatically stable layer is formed using terminal amino hyperbranched polymers and chloride salts, solving the problem of pigment brightness and viscosity compatibility. This achieves stable dispersion and transparency of high-concentration organic pigments, making it suitable for high-end furniture coating.

AI Technical Summary
Existing common color pastes have compatibility issues in maintaining vibrancy and system viscosity or storage stability, especially in the coating of high-end mahogany furniture, where it is difficult to simultaneously meet the requirements of transparency and vibrancy.
High-solids-content nano-aqueous pigment pastes are used, containing terminal amino hyperbranched polymers, chloride salts, emulsifiers, and defoamers. The dispersibility and stability of organic pigments are improved through an electrostatic stabilizing layer and hyperbranched structure. The electrostatic stabilizing layer formed by chloride ions and amino groups prevents pigment particle aggregation, and the pigment particle size is controlled at the nanoscale through grinding and filtration technology.
It achieves low viscosity and excellent dispersion stability of high-solids nano-aqueous pigments under high concentrations of organic pigments. The pigment particle size is in the nanoscale, and it can form a bright and transparent paint surface when applied, making it suitable for high-end furniture coating.
