Abstract

The invention discloses a preparation method of a microcapsule-based photo-thermal self-repairing anti-icing coating, and relates to the technical field of functional coating materials. The method comprises the following steps: acquiring core material component parameters and wall material component parameters of microcapsules, and collecting polyacrylamide concentration and dopamine polymerization duration; constructing a morphology-photo-thermal correlation model of the microcapsule, and obtaining predicted photo-thermal conversion efficiency; performing multi-target optimization on component parameters of the core material and the wall material by taking the target photo-thermal conversion efficiency as a constraint, and performing iterative inversion to obtain an optimal microcapsule configuration; preparing a primary microcapsule, and compounding a dopamine photo-thermal modified layer on the surface of the primary microcapsule to obtain a photo-thermal self-repairing microcapsule additive; the photo-thermal self-repairing microcapsule additive and epoxy resin-based paint are mixed according to a self-adaptive mass ratio, and the anti-icing coating is obtained after coating and curing. According to the method, accurate prediction of the photo-thermal conversion efficiency of the microcapsule and intelligent optimization of component parameters are realized, and the anti-icing coating with high photo-thermal conversion efficiency and rapid self-repairing capability is obtained.
