This invention relates to a method for synthesizing high-
viscosity magnesium silicate and its derivatives using complexation and dispersion effects. The method includes the following steps: mixing a
magnesium-containing compound, a
silicon-containing compound, a modified compound, and an additive, wherein the additive is one or more of a complexing agent, a dispersant, and a steric hindrance agent. After meeting the
reaction conditions, the mixture is transferred to a
pressure vessel. After the reaction is complete, the mixture is removed, cooled, and dried to obtain the high-
viscosity magnesium silicate and its derivatives. The beneficial effects are: This invention utilizes the complexing agent and the
barrier effect of the dispersant to intensify the
hydration reaction during
grinding, avoiding
particle aggregation and condensation. This ensures thorough mixing of magnesium,
silicon, and other reactants, meeting the
chemical reaction conditions. It can replace
bentonite to achieve a higher thickening effect, and the product can be made into a colorless and transparent thickening solution. Specifically, a 2 t%
aqueous solution can form a gel-like jelly with complete swelling, resulting in a wider range of applications and a better market prospect.
