Micro-foaming stone plastic floor and preparation method thereof
The invention discloses a micro-foaming stone plastic floor and a preparation method thereof. The micro-foaming stone plastic floor sequentially comprises a surface layer, a micro-foaming stone plastic base material and a mute layer from top to bottom. The expanded microsphere foaming agent and the hollow glass bead foaming agent are added into the formula of the micro-foaming stone-plastic base material layer, the expanded microsphere foaming agent is of a core-shell structure, the shell can still keep a complete sealed sphere after high-temperature expansion, and the shell has good elasticity and can bear large pressure, so that it is guaranteed that the specific gravity is reduced, good residual depression performance can still be kept, and the foaming agent plays a role in assisting foaming and reinforcing so that the floor still has good residual depression, dimensional stability and lock catch tension; in addition, the PVC foaming layer is adopted as the mute layer, and the mute layer can be directly recycled and does not need to be stripped in advance due to the fact that the PVC foaming layer is consistent with the upper main material during recycling treatment so that the recycling procedure is simplified, and the labor cost is reduced.
本发明公开了一种微发泡石塑地板及其制备方法，从上至下依次包括表皮层、微发泡石塑基材、静音层。在微发泡石塑基材层的配方中加入了膨胀微球发泡剂以及中空玻璃微珠发泡剂，前者为一种核壳结构，壳体在高温膨胀后仍能保持一个完整的密封球体，壳体有良好的弹性并可承受较大压力，因此，保证在降低比重的同时，仍能保持较好的残余凹陷性能，后者起辅助发泡及补强的作用，使得地板仍具有较好的残余凹陷、尺寸稳定性和锁扣拉力；此外，静音层采用PVC发泡层，回收处理时，由于与上部主材料一致，可直接回收，不需预先剥离，简化回收再利用程序，降低了人工成本。
