Abstract

The invention relates to the technical field of high polymer materials, in particular to micro-foamed water-based damping coating and a preparation method thereof and aims to solve the problem that the size and the density of cells of the damping coating in the prior art are difficult to control. To solve the problem, the micro-foamed water-based damping coating is prepared from a water-based emulsion serving as a main agent, damping filler serving as main filler, organic filler serving as auxiliary filler as well as a proper amount of a crosslinking agent, a catalyst, a gas foaming agent and water; specifically, the micro-foamed water-based damping coating is prepared from raw materials by weight as follows: 10-60 parts of the water-based emulsion, 20-80 parts of the damping filler, 0.5-10 parts of the organic filler, 10-50 parts of the crosslinking agent, 0.01-2 parts of the catalyst and 5-30 parts of water, wherein the temperature of the gas foaming agent ranges from 220 DEG C to 250 DEG C, and the pressure of the gas foaming agent ranges from 8 Mpa to 10 Mpa. Besides, the invention further provides a method for preparing the micro-foamed water-based damping coating. The size and density of cells of the damping coating can be controlled effectively after the coating is foamed through the gas foaming agent.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, and specifically provides a microfoaming water-based damping coating and a preparation method thereof. Background technique

[0002] Damping coatings use the viscoelastic properties of polymer materials to absorb part of the vibration energy and then release it in the form of heat (that is, mechanical loss), so as to achieve the purpose of reducing the amplitude, reducing vibration and suppressing noise. Water-based damping paint is an environmentally friendly paint that uses water as the main dispersion solvent, uses inorganic and organic matter as fillers, and does not contain toxic organic solvents. Due to the advantages of good flame resistance, high adhesion, corrosion resistance, aging resistance, high damping performance and low cost at the same time, water-based damping coatings are currently being widely used in automobiles, trains, ships, aircraft, construction machinery and o...
