Abstract

The invention provides a water-based epoxy paint and a preparation method thereof. The paint comprises an amino resin, a leveling agent, distilled water, a water-based epoxy acrylic resin, a dispersing agent, a defoaming agent, iron oxide black, superfine talcum powder, precipitated baryte, zinc phosphate, a rust inhibitor and the like; and a nano MoS2 anti-wear agent and a nano CaCO3 ultraviolet absorbent are further added to enhance the properties. By reasonably designing the component types and contents, the thickness of the paint film can reach 100 mu m above, the water resistance is greater than 240 hours, the transmittivity for ultraviolet light with the wavelength of 290-400nm is less than 0.4, the wear-resistant revolution number is up to 1000-1400, the mass loss of the paint film is less than 0.07 g / 100r, and the salt spray resistance is greater than 200 hours. The paint can be brushed on the internal and external walls of an iron building, has excellent protective effect, and is especially suitable for protecting iron building cultural relics.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based epoxy coating and a preparation method thereof. Background technique [0002] Coatings refer to materials that are coated on the surface of objects, can bond with the substrate and form a complete and tough protective film. Since its inception, coatings have been widely used in the field of architectural technology, and their functions can be summarized into three aspects, namely, the protection of buildings, decoration and other specific functions. In the prior art, in order to protect buildings, coatings should be designed according to the use environment, building type, and substrate characteristics. For example, in order to improve the fire performance of wooden buildings, the relevant coatings should have certain flame retardant properties. [0003] Iron buildings represented by iron towers have been in the outdoor environment for a long time. With the erosio...
