The invention belongs to the technical field of the technical field of water-based industrial coatings, and provides a primer for an aluminum plate curtain wall and a preparation method thereof, a composite paint for the aluminum plate curtain wall and a preparation method for the aluminum plate curtain wall. The primer for the aluminum panel curtain wall of the present invention uses the water-based hydroxy acrylic emulsion HD-8102 combined with the FB12 aliphatic isocyanate water-based blocking curing agent, so that the primer can quickly form a reticulated cross-linked film on the surface of the substrate, and the sprayed fluorocarbon topcoat will not migration, and the wet-to-wet process helps promote adhesion between primer and topcoat. At the same time, the use of King's 3525 acid drier greatly shortens the surface drying and drying time of the primer. In addition, under the combined action of FB12 aliphatic isocyanate water-based blocking curing agent, allnex 303 amino resin, cosolvent DPM, 105A thickener and 53L thickener, the leveling time of the primer is greatly shortened, and the primer is Surface coating can be carried out after leveling, which improves work efficiency. |
