Abstract

The invention relates to water-based amino acrylic stoving varnish which is prepared from the following raw materials in parts by weight: 38-51 parts of water-based hydroxyl acrylic resin, 1.5-6.3 parts of dimethylethanolamine, 35-45 parts of deionized water, 0.3-0.5 part of a defoamer, 1.2-2.0 parts of a dispersant, 5.0-6.8 parts of high color carbon black and 5.5-7.5 parts of amino resin. A water-based environment-friendly and efficient decorative protective coating is obtained to meet the performance requirements of solvent type stoving varnish, and volatilization of organic solvents is greatly reduced, the environmental damage is reduced, and the production cost can be saved, so that the water-based amino acrylic stoving varnish satisfies the industrial policy requirement on national environment protection and energy saving, and can effectively replace related solvent based coatings.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based aminoacrylic acid baking varnish. Background technique [0002] The ever-growing modern coating industry has higher and higher requirements for environmental protection. Reducing the discharge of organic solvents not only protects the environment, but also reduces costs, and is more secure for the health and safety of operators. [0003] At present, there are a considerable number of metal parts used in automobiles, household appliances, instruments and meters, and most of them need to be treated with corresponding anti-corrosion decoration. Many manufacturers are still using traditional solvent-based paints for painting. The discharge of a large amount of organic solvents pollutes the environment and poses hidden dangers to the health and environmental safety of construction workers. Therefore, inventing environmentally friendly and efficient decorat...
