Description

technical field [0001] The invention relates to an enamel, in particular to an environment-friendly polyurethane surface enamel. Background technique [0002] In the prior art, paints such as alkyd enamel, acrylic enamel, and amino baking varnish are mostly used for surface coating protection of metal products such as traffic vehicles, motors, and electrical appliances. These paints generally contain toxic solvents such as toluene and xylene. , and the content of heavy metals is not controlled, therefore, it is not an environmentally friendly paint. Some paints are not wear-resistant and have poor weather resistance, and some paints need to be baked to cure and form a film. [0003] With the progress of society, people have put forward higher and higher requirements for product quality. For enamel applied to metal surfaces, it is required to have good gloss, hard wear resistance, good weather resistance, self-drying, and environmental protection....
