Abstract

The invention belongs to the technical field of polymer composite materials, in particular to a water-based damping paint with wide temperature range heat preservation and a preparation method thereof. The water-based damping coating uses pure acrylic core-shell structure emulsion, styrene-acrylic core-shell structure emulsion, silicon-acrylic core-shell structure emulsion and VAE emulsion multi-glass transition temperature emulsion as the main bonding resin, and uses inorganic fillers and thermal insulation fillers as the main fillers. The fiber is used as a reinforcing filler, and it is prepared by introducing a nitrogen-phosphorus-based halogen-free flame retardant and a coating additive: the wide-temperature thermal insulation water-based damping coating disclosed in the present invention can be used for vibration at a temperature of -40°C-120°C The vibration and noise of the substrate is controlled, and the coating has a low thermal conductivity and anti-corrosion function, while taking into account the advantages of environmental protection, flame retardancy and simple construction.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a water-based damping paint with wide temperature range heat preservation and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards and the further development of science and technology, various large-scale infrastructure, as well as transportation tools such as automobiles and railway trains are all developing in the direction of high speed, which makes our travel faster and more convenient. Among them, it is found that the noise pollution caused by mechanical vibration is becoming more and more prominent, which affects people's living and working standards, and even causes damage to people's physical and mental health. Therefore, a lot of work has been put into vibration and noise reduction technology at home and abroad to suppress vibration and control noise. Among them, the free radical damping material composed of...
