Preparation method and application of hyperbranched polymer water soluble dispersant

The invention relates to a preparation method of a hyperbranched polymer water soluble dispersant and application of the dispersant in water-based color paste. The dispersant is poly (styrene-co-maleic anhydride)-g-(methoxypolyethylene glycol + EO-PO-EO + NR3), is biodegradable and does not contain alkylphenol. According to the preparation method of the hyperbranched polymer water soluble dispersant, the dispersant has an anionic nonionic-multi-branched-chain comb-shaped structure, the molecular structure contains aromatic rings, carboxyl, hydroxyl, amido, polyether and other pigment adsorption groups, and pigment particles are prevented from flocculating and settling by utilizing steric hindrance. The dispersant has excellent viscosity-reducing dispersibility, improves tinting strength, prevents floating and flooding, can be used for preparing resin-free / resin-system high-solid-content low-viscosity pigment concentrated slurry dispersions such as organic red, yellow and purple pigments, inorganic pigments and matting powder, can also be used for mixing and dispersing organic pigments, anti-rust pigments and fillers, and is suitable for water-based systems such as water-based color paste, water-based industrial paint, water-based ink, water-based anti-corrosion and anti-rust primer and the like.

Iron oxide red aqueous color paste for wood coating and preparation thereof

The invention relates to an iron oxide red aqueous color paste for wood coating, which comprises the following components in percentage by weight: 50-70% of iron oxide red pigment, 0.5-2.0% of surface modifier, 2.0-8.0% of wetting dispersant, 0.5-2.0% of defoamer, 0.05-0.2% of thickening agent, 0.5-2.0% of thixotropic agent, 0.1-0.5% of preservative and 20-40% of water. The color paste solid content is more than or equal to 60%, and fineness is less than 20 meshes; the color paste has strong tinting strength, stable color strength, high thixotropy and big viscosity during standby; viscosity is lowered when cutting; the color paste can be stably stored and does not have the defects of water distribution, clotting and the like; the color paste does not contain resin, can be compatible with various polymer emulsions and avoids the phenomena of flooding and floating of coating; the color paste takes water as dispersion medium and protects environment. The preparation method is as follows:firstly, preparing the surface-modified iron oxide red pigment powder, then preparing color paste predisperse body by the iron oxide red pigment powder, water and other assistants, and finally grinding to obtain the iron oxide red aqueous color paste. The color paste is used for mixing scarlet and light red aqueous wood true color coating and can be mixed with aqueous yellow color paste and aqueous blue color paste to prepare aqueous wood true color coatings with other colors.
