The sweat-resistant water-based polyurethane composite paint and the method have the advantage that the water-based polyurethane composite paint is excellent in sweat-resistant performance.

Description

Technical field: [0001] The invention relates to a coating, in particular to an anti-perspiration type water-based polyurethane composite coating and a preparation method thereof. Background technique: [0002] Polyurethane (PU for short) is a resin polymerized by polyisocyanate (containing -NCO) and macromolecular polyol (containing -OH). Due to the existence of a large number of hydrogen bonds in the polyurethane macromolecules, the intermolecular forces are large, and the macromolecular chains are stable to most chemical substances. Permeability, wear resistance, toughness and strong adhesion, etc., and there are many factors that can be changed in polyurethane macromolecules. Molecular design and structure adjustment can be carried out according to different actual conditions, so that it can better meet actual needs. Polyurethane coatings can be divided into two categories: solvent-based and water-based. [0003] With the progress of society, the development of scienc...
