Abstract

The invention belongs to the technical field of polymer composite materials, and particularly relates to a thermal insulation water-based damping coating with a wide temperature range and a preparation method thereof. The water-based damping coating is prepared with pure acrylic emulsion with a core-shell structure, styrene-acrylic emulsion with a core-shell structure, silicone acrylic core-shellstructure emulsion, VAE emulsion, and multi-glass transition temperature emulsion as main bonding resin, an inorganic filler and a thermal insulation filler as main fillers and fibers as reinforcingfillers; and a nitrogen-phosphorus halogen-free flame retardant and a coating additive are introduced to prepare the coating. The wide-temperature-range thermal-insulation water-based damping coatingcan be used for controlling the vibration noise of a vibration base material at the temperature of -40 DEG C to 120 DEG C. The coating has a relatively low heat conductivity coefficient and an anti-corrosion function, and also has the advantages of environmental protection, flame retardance and simplicity in 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...
