Abstract
A fluorocarbon resin coating and a preparation method thereof relate to a building coating and a preparation method thereof. According to the technical scheme, silicon dioxide surface hydroxy is utilized to have continuous polymerization reaction with a p-hydroxybenzoic acid surface group under existence of a catalyst, and thus the hydrophilic group on the nanometer silicon dioxide surface is modified, and nanometer silicon dioxide can be relatively well dispersed in an organic solvent. Then modified nanometer silicon dioxide fluorocarbon resin is used to prepare the composite coating. By employing the method, modification of silicon dioxide is performed under a relatively mild condition, and conventional abuses that silicon dioxide modification needs high temperature, high pressure, strong acid and strong alkali are overcome. The composite coating prepared through filling possesses relatively strong corrosion resistance, ultraviolet ageing resistance, acid-alkali resistance and hydrophobic self-cleaning performance, and is a functional coating with good prospect.
