Abstract

The invention provides a skin feeling aqueous polyurethane coating and a preparation method thereof. The aqueous polyurethane coating is prepared from the following components in parts by mass: 10-15parts of adhesive force promoted resin, 40-45 parts of hand feeling resin, 2-3 parts of a curing agent, 1-2 parts of a flatting agent, 3-5 parts of water and 45-50 parts of a cosolvent. The aqueous polyurethane coating has the advantages of being scratch-resistant, solvent-resistant, waterproof, yellowing-resistant and good in weather resistance, is moderate in price and wide in application range,and can improve the material living standard of people greatly.

Description
