Sound-absorbing damping coating containing piezoelectric ceramic fibers and preparation method of sound-absorbing damping coating
The invention discloses a sound absorption damping coating containing piezoelectric ceramic fibers and a preparation method thereof, and belongs to the technical field of chemical coating production; wherein the sound absorption damping coating comprises an acrylic emulsion, a styrene-acrylic emulsion, piezoelectric ceramic fibers, carbon fibers and other auxiliary materials, auxiliaries and the like; the acrylic emulsion comprises a first acrylic emulsion with high Tg and a second acrylic emulsion with low Tg, and the acrylic emulsion comprises a second acrylic emulsion with high Tg and a third acrylic emulsion with low Tg. The two matrix resins are matched, so that the use temperature range of the coating can be expanded, and the coating has relatively good sound absorption and damping performance in a relatively wide temperature range; meanwhile, the piezoelectric ceramic fibers and the carbon fibers in the coating are combined for use, vibration of sound in the coating can be converted into electric energy, and the electric energy is dissipated in a heat energy form through the conductive carbon fibers, so that the sound absorption damping performance of the coating is excellent.
本发明公开了一种含有压电陶瓷纤维的吸声阻尼涂料及其制备方法，属于化工涂料生产技术领域，包括丙烯酸乳液、苯丙乳液、压电陶瓷纤维、碳纤维和其他辅料、助剂等，丙烯酸乳液包括高Tg的第一丙烯酸乳液和低Tg的第二丙烯酸乳液，两种基体树脂的搭配使用，可扩大涂料的使用温度范围，在较宽的温域内均具有较好的吸声阻尼性能；同时该涂料中压电陶瓷纤维和碳纤维结合使用，可将涂料中声音的振动转化为电能，并通过导电的碳纤维以热能的形式耗散出去，因此涂料的吸声阻尼性能优异。
