Flexible mute floor and preparation method thereof
According to the flexible mute floor and the preparation method thereof, the mute layer is arranged between the two layers of PVC hard base materials, the comfortable foot feeling can be achieved, vibration and sound generated by the floor are absorbed, and the sound insulation effect is enhanced. The mute layer is arranged between the two layers of PVC hard base materials instead of being arranged at the bottom of the floor, the mute layer is supported by the hard base materials, pressure received by unit area is reduced, and improvement of residual recession is facilitated. And the mute layer is foamed by adopting the microsphere foaming agent, so that compared with a mute layer obtained by adopting a common azodicarbonamide foaming agent, the floor has a sound insulation effect, can bear relatively high pressure and has relatively high rebound resilience, so that the floor has a good residual depression degree.
本发明公开了一种柔性静音地板及其制备方法，通过在两层PVC硬质基材之间设置静音层，不仅可以达到舒适的脚感，还增加吸收震动和地板产生的声音，达到增强隔音的效果。在两层PVC硬质基材之间设置静音层，而不是在地板底部设置静音层，静音层得到硬质基材的支撑，单位面积收到的压力减小，有利于残余凹陷度改善。且静音层采用微球发泡剂进行发泡，与普通的偶氮二甲酰胺发泡剂得到的静音层相比，既有隔音效果更能承受较大压力具有较大回弹性，从而使地板具有良好的残余凹陷度。
