Problems solved by technology

However, the current water-based alkyd resin still needs to add a small amount of organic solvents and co-solvents during the preparation process, and the VOC content is high
Moreover, the existing water-based alkyd resins have poor stability and are easily hydrolyzed, resulting in poor film formation of the paint, poor film stability, and slow drying speed of the paint, which affects the use of water-based resin paints under complex outdoor construction conditions

Abstract

The invention discloses quick-drying environment-friendly water-based alkyd resin, and relates to the technical field of water-based resin. Linoleic acid and maleic anhydride are adopted to prepare water-based alkyd resin, the obtained alkyd resin contains unsaturated double bonds and can be polymerized with monomers such as methyl methacrylate and methacrylic acid to form a cross-linked structure; after the alkyd resin is prepared into paint, the hardness and the water resistance of a paint film can be improved; styrene is introduced into a resin structure through free radical polymerization, and the hydrophobic effect of styrene can further improve the stability and hydrolysis resistance of the resin; monomers with high glass transition temperature, such as acrylamide and methacrylic acid, are introduced into the resin, so that the paint film is better in stability, and the hydrophilicity of the resin is improved; the prepared quick-drying environment-friendly water-based alkyd resin is low in VOC content, good in stability and high in drying rate, molecules are of a cross-linked molecular structure, the paint prepared from the quick-drying environment-friendly water-based alkyd resin has high hardness and water resistance and good stability at high temperature, and the quick-drying environment-friendly water-based alkyd resin meets the construction requirements of outdoor complex environments.

Description

technical field [0001] The invention relates to the technical field of water-based resins, in particular to a quick-drying and environment-friendly water-based alkyd resin. Background technique [0002] Ordinary paints are mostly solvent-based, in which a large amount of organic solvents are added, such as toluene, xylene, ethyl acetate, etc. During use, organic solvents will volatilize into the air, causing serious environmental pollution and endangering human life healthy. [0003] As a new type of environmentally friendly material, water-based resin is widely used in the preparation of paints and coatings. Water-based resins use water as the medium without using or using a small amount of organic solvents, which can effectively reduce the content of volatile organic compounds (VOC). In addition, due to the advantages of bright luster and good weather resistance, water-based alkyd resin coatings are the first choice for various metallic paints and high-grade paints. How...
