Abstract

The invention relates to a water-based epoxy ester resin composition, a preparation method thereof and water-based coating prepared from the water-based epoxy ester resin composition. The waterborne epoxy ester resin composition comprises the following components in parts by weight: 10-15 parts of epoxy resin, 30-50 parts of vegetable oil fatty acid, 7-10 parts of organic phosphate, 10-15 parts of sorbitol, 5-10 parts of tricarballylic acid, 1-3 parts of ammonia water, 0.1-0.5 part of a catalyst and 5-10 parts of a solvent, and the weight sum of the sorbitol and the tricarballylic acid is twice that of the organic phosphate. According to the waterborne epoxy ester resin composition, the organic phosphate, the sorbitol and the tricarballic acid are added and interact with the epoxy resin and the vegetable oil fatty acid, so that the viscosity is improved, the stability is improved, and the corrosion resistance is enhanced.

Description

technical field [0001] The present invention relates to the technical field of components of water-based paints and a preparation method thereof, in particular to a water-based epoxy ester resin composition, a preparation method thereof, and an aqueous paint prepared by the same. Background technique [0002] Since the extensive use of solvent-based coatings can cause environmental pollution and threaten human health, their use has been banned by more and more countries. Therefore, people focus on the research and development of environmentally friendly water-based coatings. However, the existing water-based coatings generally have problems of high viscosity, inconvenient use and poor corrosion resistance. and process improvements to prepare coating products with good performance. SUMMARY OF THE INVENTION [0003] Aiming at the technical problems of high viscosity and poor corrosion resistance of the existing water-based paint, the present invention obtains a water-based ...
