Problems solved by technology

The tungoleic acid used in it leads to poor color and gloss retention of the resin film, and is prone to yellowing, so it is not suitable for topcoats that require high color and gloss retention.
[0007] Liu Dehui disclosed in the article "Synthesis of Alkyd Resin with Trihydroxyethyl Isocyanurate" (see "Painting Industry". Formula design and process flow for preparing oil-modified alkyd resin, the prepared coating dries quickly, has high hardness and good heat resistance, but the color paint has poor water resistance and is not suitable for coating standard parts of tower cranes

Abstract

The invention relates to a primer-topcoat type waterborne epoxy ester coating for tower crane standard parts, and a preparation method thereof. The coating is prepared by mixing vinyl modified epoxy ester resin, an environment-friendly pigment, a hydrolytic stable filler, a dispersing agent, an antifoaming agent, a thickener, an anti-sagging agent, a leveling agent, a wetting agent, a drier, an anti-flash-rust agent, a pH regulator, a cosolvent and deionized water. The invention further discloses the preparation method of the coating. The coating disclosed by the invention is rapid to dry, tough in paint film, high in gloss, excellent in initial water resistance, stacking resistance and weather resistance, and convenient to construct; and the preparation process is simple.

Description

technical field [0001] The invention relates to a bottom-surface-integrated water-based coating, in particular to a bottom-surface-integrated water-based epoxy ester coating for standard parts of tower cranes and a preparation method thereof. Background technique [0002] With the development of society and the improvement of residents' living standards, the people's strong yearning for a better quality of life drives the improvement of environmental protection policies. The materials used in the coating process are becoming more and more environmentally friendly, so as to avoid adverse effects on the environment, ecology and residents' lives. [0003] In consideration of construction efficiency and operating cost, coatings for tower crane standard parts require good storage stability, fast drying speed, excellent coating resistance to palletizing, high gloss, weather resistance, and excellent initial water resistance. [0004] At the painting site of standard parts of towe...
