Abstract

The invention belongs to the technical field of coatings and discloses an environmental-friendly heat-isolating high-performance aqueous damping coating and a preparation method thereof. The coating is prepared from the following components in parts by weight: 30-45 parts of an aqueous emulsion, 5-20 parts of a damping pigment and filler, 10-20 parts of rigid polyurethane foam, 15-25 parts of inorganic filler, 5-10 parts of a flame retardant, 1-5 parts of an antifreezing agent, 0.5-1.0 part of a base material wetting agent, 1.0-5.0 parts of an aqueous wetting dispersing agent, 0.5-2.0 part of an aqueous defoamer, 0.5-3.0 parts of a coupling agent, 0.5-2.0 parts of a coalescing agent, 0.5-1.5 parts of a thickener and 5-10 parts of water. The aqueous emulsion is a self-crosslinked acrylate emulsion. The coating provided by the invention has the advantages of being high in damping value, wide in damping temperature domain, good in heat-isolating property and the like and is good in covering force to a base material and strong in decorativeness. The method provided by the invention is simple and easy to operate, and green and environmental-friendly.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to an environmentally friendly heat-insulating high-performance water-based damping coating and a preparation method thereof. Background technique [0002] Damping coatings use the viscoelastic properties of organic polymer materials to convert the vibration mechanical energy of sound waves into thermal energy and dissipate them (ie, mechanical loss), thereby achieving the purpose of reducing amplitude, reducing vibration, and suppressing noise. [0003] As the society pays more and more attention to environmental protection, water-based damping coatings are currently being used in the fields of automobiles, trains, ships, aircraft, construction machinery and other household appliances to play the role of sound insulation, sound absorption, vibration reduction and heat preservation. The damping coating can play a damping and vibration reduction effect, which mainly depends on the int...
