Problems solved by technology

Ammonia and organic amines generally have a special unpleasant smell, which cannot meet the requirements of low VOC or zero VOC for coatings
The high price of 2-amino-2-methyl-1-propanol (trade name AMP95) hinders its widespread use in the field of architectural coatings

Abstract

The invention relates to an organosilicon composition. The organosilicon composition can be used for adjusting the pH value of a water-based building coating.

Description

technical field [0001] The present invention relates to a silicone composition. The composition of the invention can be used for water-based architectural coatings to adjust pH. Background technique [0002] pH adjuster is an additive commonly used in water-based architectural coatings. Although its dosage is relatively low, it plays an essential role in maintaining the stability of architectural coatings. [0003] As we all know, when synthesizing a polymer emulsion, a small amount of polymerizable acrylic acid or methacrylic acid is usually added, and after the polymerization, a small amount of pH regulator needs to be added to keep the emulsion in an alkaline state. [0004] In the preparation process of water-based architectural coatings, the cellulose in the formula needs to be dissolved under slightly alkaline conditions. [0005] The alkali-swellable emulsion thickener in the formula is usually acidic. Only when it encounters an alkaline pH regulator, it reacts to f...
