Water-based sound insulation coating as well as preparation method and application thereof
The present invention relates to a water-based sound insulation coating and a preparation method and application thereof, the water-based sound insulation coating comprises a first component and a second component, the first component comprises a polymer elastic emulsion, the second component comprises cement, a filler and a sound insulation material, the mass ratio of the cement to the filler to the sound insulation material is 1: 0.1-10: 0.6-10, and the mass ratio of the polymer elastic emulsion to the sound insulation material is 1: 0.1-10: 0.6-10. The sound insulation material is composed of elastic damping rubber, mica powder and asbestos-free mineral fiber according to the mass ratio of 1: (0.05-0.5): (0.1-1), and the water-based sound insulation coating further comprises nano sodium silicate. On one hand, the inorganic cross-linked network material formed by reaction of the cement and the nano sodium silicate with the high-molecular elastic emulsion is matched with the filler for use, so that the obtained sound insulation coating has higher surface density, and on the other hand, the sound insulation material composed of the elastic damping rubber, the mica powder and the asbestos-free mineral fibers is combined for use, so that the sound insulation effect is better. The sound insulation coating with three functions of shock absorption, sound insulation and sound absorption can be obtained, and a better sound insulation effect is achieved.
本发明涉及一种水性隔音涂料及其制备方法和应用，包括第一组分和第二组分，第一组分包括高分子弹性乳液，第二组分包括水泥、填料和隔音材料，水泥、填料和隔音材料的质量比为1：0.1～10：0.6～10，隔音材料为弹性阻尼橡胶、云母粉和无石棉矿物纤维按质量比1:0.05～0.5:0.1～1组成，水性隔音涂料还包括纳米硅酸钠。本发明一方面，利用水泥和纳米硅酸钠与高分子弹性乳液反应形成的无机交联网络材料配合填料的使用使得获得的隔音涂层具有更高的面密度，另一方面，结合由弹性阻尼橡胶、云母粉和无石棉矿物纤维构成的隔音材料的使用，能够获得兼具减震、隔音和吸音三重功能的隔音涂层，具有更好的隔音效果。
