Abstract

The invention relates to APAO-modified water-based alkyd resin and a preparation method thereof. The APAO-modified water-based alkyd resin is composed of the following components in parts by weight: 20.0-35.0 parts of vegetable oil fatty acid, 5.0-10.0 parts of maleic anhydride grafted APAO, 20.0-42.0 parts of a polyacid, 25.0-60.0 parts of a polyol, 10.0-20.0 parts of xylene, 2.5-5.0 parts of n-heptanoic acid, 3.5-7.0 parts of dimethylolpropionic acid, 4.0-12.0 parts of a neutralizing agent, and 100.0-150.0 parts of deionized water. The APAO modified water-based alkyd resin prepared by the method has the characteristics of good adhesion, water resistance, good fullness, and good sagging resistance, can be used for interior and exterior wall coatings, water-based industrial coatings, water-based floor coatings, water-based wood coatings and the like, and has huge application potential.

Description

technical field [0001] The invention relates to a modified water-based alkyd resin, in particular to an APAO modified water-based alkyd resin and a preparation method thereof, belonging to the technical field of water-based resin synthesis. Background technique [0002] Traditional solvent-based alkyd resins contain a large amount of organic solvents, especially benzene solvents, which volatilize into the atmosphere after drying, causing a large amount of first pollution to the air. A large amount of hydrocarbon solvents are used in alkyd resins, which can promote Photochemical smog causes secondary pollution to the air and is also a massive waste of resources and energy. Therefore, water-based alkyd resin is the development direction of alkyd resin, and it also meets the requirements of environmental protection. Water-based alkyd resin uses water as the dispersion medium, which is the most effective environment-friendly resin for reducing pollution and saving resources. ...
