Description

一种多层复合地板及其生产方法
技术领域
本发明涉及一种多层复合地板及其生产方法，尤其涉及一种多层复合地板及其生产方法。
背景技术
随着经济快速发展，木材资源的开发越来越快，地球植被日渐消退，人类的生存环境岌岌可危。
而地板产业对于木材的需求量极大，因此如何在地板产业中减少木材的使用成为了解决环境问题的关键。但是，在地板生产中，木材又具有很多难以替代的特性。
目前，有一些厂家已经开始使用塑料材质去替换木材，但是它们一般都是使用整体塑料(或木塑合成材料)做成地板形状，这种地板在强度、质地手感等多方面都无法比及实木材质的地板。
发明内容
本发明的目的在于，提供一种多层复合地板及其生产方法。本发明可以有效地减少木材资源的使用，更加节能环保，同时具有较高的结构强度和整体稳定性。
为解决上述技术问题，本发明提供的技术方案如下：一种多层复合地板，其特点是：包括PVC基材层,PVC基材层的上表面设有面皮层，面皮层上设有油漆层，所述面皮层为木皮或竹皮，所述面皮层和PVC基材层之间设有聚氨酯粘接层。
上述的多层复合地板中，所述PVC基材层的下表面设有3mm～5mm的EVA底层。
前述的多层复合地板中，所述PVC基材层的上表面和下表面均设有多个沿地板长度方向的V型槽，不仅可以增加两层材料的结合强度，而且可以作为应力槽来提高地板的整体强度，不仅不易翘曲，而且负载能力大大增强。
前述的多层复合地板中，所述V型槽的开口角度为25～50°，深度为1.5mm～2.5mm，各个V型槽的间距为12mm～35mm，可最大化提高结合强度和整体强度。
前述的多层复合地板中，所述PVC基材层为PVC发泡材料层。
前述的多层复合地板中，所述面皮层与PVC基材层的厚度比例为1∶3至1∶5。
前述的多层复合地板的多层复合地板的生产方法，具体包括以下步骤：
a、对面皮层进行表面碳化，形成0.2mm～0.3mm的碳化层；
b、将表面碳化的面皮层置于聚氨酯浆液中浸泡1～1.5小时；
c、将面皮层从聚氨酯浆液中取出，刮除其中一面的残留聚氨酯，另一面粘压在PVC基材层上；
d、固化聚氨酯；
e、在面皮层表面涂覆油漆层。
前述的多层复合地板的生产方法中，所述PVC基材层由PVC材料挤压成型，并挤压得到直落式锁扣结构。
前述的多层复合地板的生产方法中，当需要增加EVA底层时，所述步骤e和d之间还设有将EVA底层热压在PVC基材层未粘贴面皮层的一面的步骤。
与现有技术相比，本发明通过使用PVC作为基材层,并使用木质或竹质材料进行复合，可以得到具有较高的结构强度和整体稳定性的地板。本发明可以减少木材的使用，更加的节能环保。而且本发明的地板相对于普通复合地板，具有更高的尺寸稳定性，不易出现翘曲变形的情况。另外本发明还具有防水、静音的特点。
本发明的生产方法中，利用了碳化后产生的孔隙去吸收聚氨酯，固化后面皮层可具有更高的强度。本发明的方法，工艺精简，相对于传统木地板的加工具有更高的生产效率。
