Abstract

The invention provides a formula system and a manufacturing method of high-hardness waterborne acrylic acid modified alkyd resin baking enamel. The matrix of high-hardness waterborne alkyd resin is formed by mixing benzoic acid modified alkyd resin, waterborne acrylic acid modified alkyd resin, epoxy modified acrylic acid resin and amine resin. In the formula system, n-butanol is adopted as a film-forming agent, zinc oxide powder and cellulose powder are added as a filling supplement, and a titanate coupling agent is adopted to improve the interfacial properties in the system and improves thedispersibility of the filler while enhancing the adhesion to a metal substrate together with phosphate. Through the combination of the above formula, a final product has better gloss, high hardness, high adhesion, good weather resistance and good water washing resistance after curing at a high temperature than conventional water-based alkyd resin, and has a great advantage.

Description

technical field [0001] The invention relates to the field of high-temperature-resistant coatings, in particular to a high-hardness water-based acrylic modified alkyd resin baking varnish. Background technique [0002] With the development of society and the advancement of science and technology, environmental protection issues have gradually become the mainstream awareness of people, and the country's environmental protection requirements for industrial enterprises are also getting higher and higher. Specifically, in terms of coatings, it is limited to the mandatory requirements of VOC. Many solvent-based coatings are It is no longer suitable for the current production and life. In view of this, water-based coatings with water as the dispersion medium have begun to flourish worldwide due to their good environmental affinity and safety in use. Among them, water-based alkyd resin coatings have become the most widely used water-based coatings because of their low price and good...
