Abstract

Provided is a multifunctional thickener for waterborne paint. The multifunctional thickener for the waterborne paint is prepared through the steps that 620-640 parts by weight of propylene glycol is added into a vessel, 18-22 parts by weight of pure water is added into the vessel, and stirring is conducted for 8 min to 15 min under the stirring condition of 400 revolutions / minute to 600 revolutions / minute; 11-15 parts by weight of wetting dispersant is added into the vessel, and stirring is conducted for 12 min to 18 min under the stirring condition of 400 revolutions / minute to 600 revolutions / minute; 340-360 parts by weight of xanthan gum is added into the vessel, and stirring is conducted for 25 min to 35 min under the stirring condition of 800 revolutions / minute to 1,000 revolutions / minute. The multifunctional thickener for the waterborne paint can achieve the anti-settling, anti-layering and anti-sagging effects in the production and use processes of the waterborne paint and can achieve thickening in paint with different pH values.

Description

[0001] technical field [0002] The invention relates to a multifunctional thickener for water-based paint. Background technique [0003] Thickener for water-based paint is a kind of rheological additive, which can thicken the paint, prevent sagging during construction, and endow the paint with excellent mechanical properties and storage stability. For water-based paints with low viscosity, the thickener is essentially a rheological additive. After adding the thickener, it can adjust the rheology of the paint, thicken the adhesive and sealant, prevent the filler from settling, and Endow the coating with good physical and mechanical stability, control the rheology of the construction process (no sagging, no dripping, no flying liquid when sizing), and also play a role in reducing costs. However, the existing thickeners for paints cannot achieve the effect of thickening in paints with different pH values, and their performance in anti-settling, anti-lamination, and anti-sag...
