Abstract

The invention provides water-based baking epoxy paint, which is composed of a component A and a component B according to the mass ratio of 2: (1-2), and the component A is composed of water-based epoxy resin, color paste and a dispersing agent; and the component B is composed of a waterborne epoxy curing agent, a pigment filler, an antifoaming agent, a wetting agent and a leveling agent. The water-based baking epoxy paint provided by the invention is composed of the component A and the component B, has the characteristics of nonflammability and no harm to human bodies, can be cured by medium-temperature heating (100-120 DEG C), has good mechanical properties, scrubbing resistance, chemical resistance, salt spray resistance and the like after curing, is suitable for an assembly line production process. and is widely applied to adhesion, coating (electromechanical coating), pouring, encapsulation, impregnation, composite materials and the like, has good adhesion and strong cohesiveness,and has excellent high and low temperature resistance, and the alkali resistance of the hydrophilic aluminum foil anticorrosive coating exceeds 10 minutes.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based baking epoxy paint. Background technique [0002] As an important coating, epoxy paint has good corrosion resistance, excellent mechanical properties, wear resistance and impact resistance, heat resistance and water resistance, and non-toxic coating film. It is widely used in coating anticorrosion process, floor coating, automobile primer , metal anti-corrosion, chemical anti-corrosion, etc. However, the epoxy paint currently used has poor weather resistance, is easy to pulverize and change color, is poor in decoration, difficult to maintain gloss, has high requirements for construction environment, and is not resistant to scrubbing, and has poor resistance to chemicals and salt spray. Contents of the invention [0003] In view of the problems pointed out in the background technology, the present invention proposes a water-based baking epoxy paint, which has goo...
