Abstract

The invention relates to a quick-drying high-solid low-viscosity epoxy paint for engineering machinery and a preparation method thereof. The paint is prepared by blending a component A and a componentB, wherein the component A comprises bisphenol F epoxy resin, hydroxymethyl bisphenol A epoxy resin, a dispersing agent, a leveling agent, an anti-settling agent, special liquid resin, pigment and filler, an antirust pigment and a solvent; and the component B comprises a modified polyamide curing agent, modified aliphatic Mannich base, a curing accelerator and a solvent; and the solvent is xyleneand n-butyl alcohol. The invention further discloses a preparation method of the paint. The paint is high in solid content and low in viscosity, air spraying or airless spraying can be conducted during construction, and the one-time film forming thickness is larger than or equal to 100 micrometers; the construction efficiency is high; a coating film has a quick drying speed, and the surface drying time is less than or equal to 10min; the coating has strong adhesion to a substrate, good impact resistance, good flexibility, and excellent salt spray resistance and medium resistance; the VOC emission is low, and environmental friendliness is achieved; the preparation method of the paint is simple to operate and is suitable for industrial production.

Description

technical field [0001] The invention relates to a high-solid and low-viscosity epoxy coating and a preparation method thereof, in particular to a high-solid and low-viscosity epoxy coating for quick-drying engineering machinery and a preparation method thereof. Background technique [0002] With the rapid development of modern industry and the continuous strengthening of people's awareness of environmental protection, the development and research and development of coatings are also developing in the direction of 5E, that is, excellent quality, economy, efficiency, ecology, and energy. Countries around the world are increasingly restricting VOC emissions, which promotes the development of high-solid coatings. In the development of heavy-duty coatings in the 21st century, as people pay more and more attention to environmental protection, it is particularly important to control the solvent content in coatings for heavy-duty coatings. [0003] Modern heavy-duty anti-corrosion ...
