摘要
通过改变组分比、无机颜填料类型及引入极性单体(AA、HEA)的比例,系统研究了涂层的力学性能和噪音衰减程度。结果表明,主链结构中增加旋转阻力大的单体,阻尼值增高。共聚链段中引入极性单体,不仅改善体系的相容性,而且提高涂层的附着力。无机填料提高了阻尼值,也使阻尼温度区间加宽,片状结构的云母效果最佳。添加无机填料,有助于噪音衰减,可以制备衰减噪音5~8dB/mm的阻尼涂料。
AbstractA PS/PA LIPN latex damping coating has been de-veloped, and the mechanical properties and dampingextent for noise of the coating film have been studiedsystematically through change of component ratio ,in-organic fillers and introduction of polar monomers (e.g. AA, HEA). It has shown that increase of the vol-ume of rotation prohibited monomer in the main chaincan not only improve the compatibility of the system .but also increase the adhesion of the coating film. Ad-dition of inorganic fillers can increase the damping ef-fective value ,as well as expand the temperature rangefor effective damping ,and flake structure fillers ,e. g.mica has shown the best result. Addrtion of inorganicfillers also helps reduce the noise and formulate adamping coating that can reduce the noise 5~8 dB/mm .
