Embodiment Construction

[0008] An environment-friendly polyurethane surface enamel, comprising hydroxyacrylic resin, biuret, non-heavy metal pigment, butyl acetate, and low-distillation range aromatic hydrocarbon solvent, wherein the weight percent content of each component is respectively: the described hydroxyacrylic resin is 50%, the biuret is 15%, the non-heavy metal pigment is 20%, the butyl acetate is 10%, and the low-distillation aromatic hydrocarbon solvent is 4.95%.

[0009] The distillation range of the low-distillation-range aromatic hydrocarbon solvent is 155-175°C.

[0010] In the present invention, chemical additives that do not affect its performance can be added, such as adding 0.05% by weight of hexamethyldisiloxane as a leveling agent. Methyldisiloxane is commonly known as silicon ether, and its molecular formula is: (CH 3 ) 3 SiOSi (CH 3 ) 3 , its structural formula is as follows:

[0011]

[0012] Methyldisiloxane can increase the compatibility of polyurethane slurry and s...

Abstract

The invention discloses an environment-friendly polyurethane surface enamel comprising the following raw materials (by weight percent): hydroxy acrylic resin 40-60%, biuret 10-20%, non-metal pigment 15-30%, butyl acetate 5-15%, and low distillation range aromatic solvent 3-10%.

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....
