Problems solved by technology

This is because the absorption of CO2 will lead to silicate precipitation gelation. At this time, there is no dehydration between the silicon hydroxyl groups to form a siloxane network structure, so it cannot be effectively formed into a film, and it is easy to cause a large number of holes after the water evaporates.
Therefore, this kind of low modulus and low solid content is the root cause of poor paint film quality

Abstract

The invention belongs to the field of coatings. Corresponding products can be applicable to industrial corrosion prevention and architectural ornament. The invention discloses a multifunctional environmental-friendly inorganic silicate coating which comprises a component A and a component B, wherein the component A comprises pigments; the component B comprises a silicate solution and a modifier. The coating is excellent in stability and excellent in film-forming effect.

Description

technical field [0001] The invention relates to the field of coatings, and the corresponding product is applicable to industrial anticorrosion and architectural decoration, and is a multifunctional and environment-friendly inorganic silicate coating. Background technique [0002] Water-based inorganic coatings usually use inorganic polymers such as alkali metal silicate and silica sol as film-formers. Coatings in which silicate is used as the main film former have wider applications. Due to the good corrosion resistance of silicate coatings, especially the outstanding acid resistance and weather resistance, it has unique performance advantages in outdoor engineering anti-corrosion construction. As early as the 1970s and 1980s, silicate coatings, especially inorganic zinc silicate coatings, were widely used in the field of engineering anticorrosion abroad. [0003] Inorganic zinc silicate coating is a two-component coating, with silicate (sodium silicate, potassium silicate...
