Abstract

The invention belongs to the technical field of water-based industrial coatings, and provides a primer for an aluminum plate curtain wall, a preparation method of the primer, a composite paint vehicle for the aluminum plate curtain wall and a preparation method of the aluminum plate curtain wall. According to the primer for the aluminum plate curtain wall, the water-based hydroxyl acrylic emulsion HD-8102 is combined with the FB12 aliphatic isocyanate water-based closed curing agent, a net-shaped cross-linked film can be rapidly formed on the surface of a base plate through the primer, fluorocarbon finish paint cannot migrate after being sprayed, and a wet-to-wet process is beneficial to promoting the adhesive force between the primer and the finish paint. Meanwhile, due to the use of a King's 3525 acid drier, the surface drying time and the drying time of the primer are greatly shortened. Besides, under the combined action of the FB12 aliphatic isocyanate water-based closed curing agent, the Zhanxin 303 amino resin, the cosolvent DPM, the 105A thickening agent and the 53L thickening agent, the leveling time of the primer is greatly shortened, so that the primer can be subjected to surface coating after being leveled, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water-based industrial coatings, in particular to a primer for aluminum curtain walls and a preparation method thereof, a composite paint for aluminum curtain walls and a preparation method for aluminum curtain walls. Background technique [0002] With the rapid development of cities and the continuous improvement of living standards, people have higher and higher requirements for the exterior of buildings. Lime, tiles, mosaics and natural stone were the earliest materials used for exterior decoration of buildings; tiles and mosaics are often dropped and hurt people due to thermal expansion and contraction, endangering human life; , the situation of injuring people, there are also high prices, non-renewable, waste of resources and serious environmental pollution in mining. With the improvement of people's awareness of environmental protection and safety, ceramic tiles, mosaics and natural stones are grad...
