Novel Damping Coating Integrating Shock Absorption, Noise Reduction and Heat Insulation and Preparation Method Thereof
The invention discloses a novel damping material for shock absorption, noise reduction and heat insulation and a preparation method thereof. The damping coating of the invention is prepared from the following raw materials in percentage by weight: 1-5% of deionized water, 0.05-0.1% of BR3 dispersant, 0.05-0.1% of wetting agent, 0.1-0.2% of dodecyl alcohol ester, 0.1-0.2% of amine neutralizer, 0.05-0.1% of antifoamer, 0.1-0.2% of thickener, 40-60% of binuclear shell epoxy modified acrylic emulsion resin, 5-10% of mica, 5-10% of heavy calcium, 5-10% of basalt powder, 5-10% of diatomite, 5-10% of aluminum hydroxide, 3-5% of mesoporous aluminum oxide, 3-5% of mesoporous silica, 3-5% OofCO304 fiber and 3-5% of seven-hole hollow polyester staple fiber. According to the invention, raw materials such as binuclear shell epoxy modified acrylic emulsion resin, mica, mesoporous alumina, mesoporous silica, heavy calcium, basalt, diatomite, aluminum hydroxide, C0304 fiber, seven-hole hollow polyester staple fiber and the like are reasonably proportioned. Due to the high hardness of the inorganic filler, the inorganic filler generates friction with the polymer hard chain during vibration, so that kinetic energy generated by vibration is converted into heat energy to dissipate, and the goal of realizing high damping performance in a wide temperature range is achieved. The inorganic filler is used in petrochemical industry, aerospace, mechanical power, transportation, military and national defense, and civil buildings. It has obvious shock absorption, noise reduction and heat preservation effects, and can curb noise from the source by reducing mechanical vibration, thus overcoming the disadvantages of traditional sound insulation materials such as high density, large thickness and high cost, which are not conducive to practical application. The inorganic filler prepares a damping coating which is cheap, easy to obtain, light and good in barrier effect.
