Problems solved by technology

However, some manufacturers also use the coating system of electrophoretic primer and acrylic polyurethane topcoat. The main reason for using this coating system is that some structural parts have complex structures. The utilization rate is low, resulting in a lot of waste, which is not conducive to cost saving, and the use of electrophoretic coating can improve the utilization rate of paint and reduce paint waste
However, although the use of electrophoretic coatings on these complex structural parts improves the utilization rate of the coatings and can also meet the anti-corrosion requirements, due to the particularity of the electrophoretic coating formulations and the differences between various electrophoretic coating manufacturers, some water-based construction machinery topcoats cannot be used. Effective adhesion of this coating cannot provide long-term anti-corrosion decoration effect for construction machinery and equipment

Abstract

The invention relates to a high-matching-property high-weather-resistance water-based engineering machinery finish paint and a preparation method thereof. The water-based engineering machinery finish paint is composed of a component A main agent and a component B curing agent, wherein the component A main agent is prepared by mixing the following raw materials: a water-based hydroxyl-containing acrylic acid dispersion, a cosolvent, a wetting agent, an antifoaming agent, a pigment filler, a dispersing agent, a leveling agent, a rheological additive and deionized water; and the component B curing agent is prepared by mixing the following raw materials: water-based modified polyisocyanate and a cosolvent. The invention further discloses the preparation method of the water-based engineering machinery finish paint. The water-based engineering machinery finish paint disclosed by the invention has good adhesion to an electrophoretic coating and a conventional epoxy primer coating, and a formed paint film has the advantages of high hardness, high fullness, good brilliance, high gloss, excellent solvent resistance, excellent aging resistance and the like.

Description

technical field [0001] The invention relates to a water-based engineering machinery topcoat, in particular to a highly compatible and highly weather-resistant water-based engineering machinery topcoat acting on electrophoretic coatings and conventional epoxy primer coatings and a preparation method thereof. Background technique [0002] At present, most of the metal surfaces of construction machinery and special vehicles in my country are painted with epoxy primers and polyurethane topcoats. However, some manufacturers also use the coating system of electrophoretic primer and acrylic polyurethane topcoat. The main reason for using this coating system is that some structural parts have complex structures. The low utilization rate causes a lot of waste, which is not conducive to cost saving. However, the use of electrophoretic coating can improve the utilization rate of paint and reduce paint waste. However, although the use of electrophoretic coatings on these complex struct...
