Abstract

The invention discloses a wide-temperature range and high-performance water-based damping paint. By the compounding of core-shell structure water-based polyacrylic emulsion and interpenetrated network structure water-based epoxy / polyurethane emulsion, the paint is combined with the advantages of three resins including acrylic resin, epoxy resin and polyurethane resin, based on different viscoelastic state temperature scopes of acrylic resin and epoxy / polyurethane resin, the temperature range after compounding is expanded, the wide temperature range scope from -20 to 60 DEG C is realized, and the paint is excellent in mechanical property; meanwhile, functional fillers including hindered phenol, lamellar mica powder and flake graphite are added, by the friction between viscoelastic state macromolecular chain segments, the hydrogen-bond interaction between the small molecular hindered phenol, the friction between the lamellar filler mica powder and the flake graphite, and the friction between the fillers and the macromolecular chain segment, the damping performance of the material is improved; with the additional flame retardant, the flame retardant property of the material is improved, so that the paint is environment-friendly and safe, and the oxygen index of the paint is more than 30; the technology is simple, special equipment is not needed, and the price is low.

Description

technical field [0001] The present invention relates to a preparation method of a high-performance water-based damping coating in a wide temperature range, in particular to a high-performance water-based damping coating in a wide temperature range and a preparation method thereof ， It belongs to the field of paint. Background technique [0002] All kinds of mechanical equipment will generate vibration and noise to varying degrees during operation. The polymer composite damping material absorbs the vibration through the friction between the viscoelastic macromolecular segments, the small molecular fillers, and the chain segment and the filler. The energy is converted into heat and dissipated, thus playing the role of shock and noise reduction. At present, there are many kinds of damping coatings at home and abroad. According to the type of solvent, there are mainly solvent-based and water-based. Traditional solvent-based products have problems such as harmful gas volatilizat...
