AI Technical Summary

Problems solved by technology

The main disadvantage of this kind of coating is that the elasticity of the coating film is easy to age, which leads to a decrease in the elongation rate, and cannot effectively protect the strength of the bottom layer of the wall, resulting in cracking and falling off of the wall surface, which not only affects the appearance of the building, but also cracks on the wall surface, causing the wall surface to crack and fall off. surface leaking

Abstract

The invention discloses an aqueous nano-coating. The aqueous nano-coating is characterized by being prepared from a component A and a component B, wherein the formula of the component A is as follows: 60-80 parts of hydroxyl polyacrylate dispersoid, 0.2-0.3 parts of leveling wetting agent, 12-25 parts of polyacrylic acid, and 20-30 parts of polyisocyanates; the component B comprises 6-9 parts of polyisocyanate curing agent; the aqueous nano-coating is prepared through the following steps: adding the component A to a container according to the formula, stirring at the middle speed, sequentially adding deionized water, the leveling wetting agent, a cosolvent, a defoaming agent and a thickening agent, dispersing for 20-30min at high speed, adding the water-dispersibility polyisocyanate curing agent according to the certain proportion, and fully stirring to obtain the aqueous nano-coating.

Description

technical field [0001] The invention belongs to the technical field of coatings and paints, in particular to a water-based nano coating. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. Water-based coatings include three types: water-soluble coatings, water-dilutable coatings, and water-dispersible coatings. Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products. There are also water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins, etc.; water-dilutable coatings refer to coatings prepared after emulsified emulsions become films, which are solvent-based resins dissolved in organic solvents, and then re-emulsified. With the help of strong mechanical stirring, the resin is dispersed in water to form an emulsion, which is called a post-emulsification emulsion. The paint ...
