Modified aqueous alkyd resin coating

Abstract

The invention discloses modified aqueous alkyd resin coating, which comprises the following raw materials in parts by weight: 70-85 parts of acrylic-modified aqueous alkyd resin, 10-25 parts of aqueous epoxide resin, 10-25 parts of nano silica sol, 2-5 parts of amino resin, 2-5 parts of rutile-type titanium dioxide, 2-6 parts of nano calcium carbonate, 1-4 parts of nano titanium dioxide, 2-5 parts of aluminum oxide, 2-6 parts of nano ferric oxide, 0.1-0.5 part of nano silver, 0.3-1 part of polyethylene glycol, 0.1-0.5 part of proprylene glycol monomethyl ether, 0.2-1 part of ethylene glycol butyl ether, 0.5-1.5 parts of triethanolamine, 0.1-0.5 part of benzotriazole, 0.05-0.5 part of a dispersant, 0.1-0.8 part of a defoaming agent, 1-4 part of a dryer, 1-3 parts of a silane coupling agent and 20-50 parts of water. The modified aqueous alkyd resin, coating is high in hardness and excellent in impact resistance, water resistance, corrosion resistance and bacterium resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a modified water-based alkyd resin coating. Background technique [0002] Coatings are indispensable materials for national production and various sectors of the economy, and are widely used in the decoration of buildings and industrial products, as well as the anti-corrosion coating protection of various hardware and vehicles. Alkyd resin coatings have the advantages of cheap and easy-to-obtain raw materials, good coating adhesion, brightness, plumpness, and good wetting performance on pigments, and have good construction properties. They have always occupied a considerable proportion in the field of traditional coatings, but traditional Alkyd resin coatings contain a large amount of organic solvents, and they are often diluted with organic solvents during use. These organic solvents volatilize into the atmosphere during construction and have a serious impact on the human body ...

Alkyd resin coatings have the advantages of cheap and easy-to-obtain raw materials, good coating adhesion, brightness, plumpness, and good wetting performance on pigments, and have good construction properties. They have always occupied a considerable proportion in the field of traditional coatings, but traditional Alkyd resin coatings contain a large amount of organic solvents, and they are often diluted with organic solvents during use. These organic solvents volatilize into the atmosphere during construction and have a serious impact on the human body and the ecological environment. In addition, the hardness and water resistance of alkyd resin coatings Poor performance and corrosion resistance, need to be modified
