Problems solved by technology

[0005] When consulting literature, market research and customer needs, it is found that some mechanical occasions generate a lot of heat, and the damping coating is generally a thick coating type. Due to its sound insulation requirements, there will be some gaps and the heat preservation function is more prominent. Therefore, the general water-based The damping coating will prevent the temperature of the mechanical parts from dissipating well, causing the temperature to be too high and reducing the mechanical life

Abstract

The invention belongs to the technical field of polymer water-based composite materials, and particularly relates to a high-thermal-conductivity water-based damping coating and a preparation method thereof. The water-based damping coating is prepared by taking a vinyl versatate-acrylate emulsion, a water-based epoxy emulsion and a core-shell-structured silicone acrylic emulsion multi-glass transition temperature emulsion as main bonding resins, an inorganic filler as a main filler and adding a coating additive. The high-thermal-conductivity water-based damping coating disclosed by the invention can be used for controlling the vibration noise of a vibration base material at a temperature of 30-130 DEG C; and the coating has a high heat conductivity coefficient and anti-corrosion and flame-retardant functions, can be dried at normal temperature and at a high temperature of 120-160 DEG C, and has the advantages of environmental protection, flame retardance and simple construction.
