Abstract

The invention belongs to the technical field of finish paint for buildings, and particularly discloses finish paint for a building aluminum veneer curtain wall and a preparation method thereof. The finish paint for the building aluminum veneer curtain wall comprises a component A and a component B. The component A is prepared from the following raw materials: fluorocarbon resin, filler, modified carbon nanotubes, methyl methacrylate resin, silica sol, a dispersing agent, 3-(trihydroxysilyl) propyl methyl phosphate, 4-aminophenylboronic acid, diethylenetriamine, ethylene glycol butyl ether, a defoaming agent, a thickening agent, dioctyl phthalate, a pH regulator and a solvent; and the component B is prepared from hexamethylene diisocyanate resin and sodium hexametaphosphate. On the basis of good corrosion resistance, the finish paint also has good heat insulation and wear resistance.

Description

technical field [0001] The invention relates to the technical field of architectural topcoats, in particular to a topcoat for architectural aluminum veneer curtain walls and a preparation method thereof. Background technique [0002] With the development of the construction industry, people have higher and higher requirements for building curtain walls, which need to have better properties such as flame retardancy, heat insulation, corrosion resistance, and wear resistance. [0003] Fluorocarbon coatings refer to coatings with fluororesin as the main film-forming substance; also known as fluorocarbon coatings, fluorine coatings, fluororesin coatings, etc. Among all kinds of coatings, fluororesin coatings have particularly superior properties due to the high electronegativity of the introduced fluorine element and strong carbon-fluorine bond energy. The performance of the curtain wall can be improved by spraying the fluorocarbon coating on the building curtain wall to form a...
