一种NON-PVC基材类 3D打印地板及其制备方法 技术领域
本发明涉及一种室内地板，尤其涉及一种NON-PVC基材类3D打印地板，本发明还涉及一种NON-PVC基材类3D打印地板的制备方法。
 背景技术
作为装饰材料中的一种，木质装饰板因其自然、质朴的独特风格得到了广泛应用。但因现有木质装饰板的面料一般都采用木皮、竹片等材料，产品材质比较单一，而且图案也比较简单，与当前不断丰富发展的多元化装饰风格相比，其装饰效果显得越来越平淡，无法满足当前广大消费者的使用及审美需求。
为此，专利公开号为CN208686011U的中国实用新型专利于2019年4月2日公开了一种3D打印实木地板，利用UV打印工艺形成UV油印层，可以根据预设样式或用户定制样式进行打印生产，再于表层UV淋漆形成保护层，不仅使得地板款式多彩多变，效果精细，而且生产加工方便，通过漆面保护层的厚度或材质选择可解决地板耐磨度问题，同时满足用户的视觉和对产品品质的追求。但是由于采用实木，对生态环境造成极大的影响，而且实木地板价格高，后期维护保养成本也较高。
 技术问题
申请人也针对上述缺陷提出过一种生物质复合材料贴合木皮地板工艺及复合地板，专利公开号为CN110593518A，公开于2019年12月20日，通过含有生物质的聚烯烃基层代替实木，在聚烯烃基层上贴覆实木皮。但是也存在一些缺陷，例如实木皮与聚烯烃基层之间的连接牢固度不佳，随着使用年限的延长，或者地板所处环境的影响，实木层容易发生翘曲，与聚烯烃基层发生脱离。
 技术解决方案
本发明提供了一种NON-PVC基材类3D打印地板，采用NON-PVC的材质作为基材，通过铺设实木层来达到仿真实木的效果，借助平衡层来克服现有的此类复合地板实木层容易发生翘曲，与聚烯烃基层发生脱离的缺陷。
本发明解决上述问题的技术方案是：
一种NON-PVC基材类3D打印地板，至少包括：
用于形成地板主体并提供地板强度的NON-PVC基材层；
形成于所述NON-PVC基材层之上用于提供仿真效果的实木层；
用于平衡NON-PVC基材层与实木层之间涨缩差异、且位于NON-PVC基材层与实木层之间的平衡层；
位于所述实木层之上的图案层；
位于所述图案层之上、提供3D立体效果的凹凸效果层。
上述技术方案，通过采用非PCV基材，达到降低成本、更加环保的效果；
通过贴合实木层，来实现仿真效果，弥补非PCV基材的不足；
设置图案层和凹凸效果层，来实现地板的美观、多样性，满足不同客户的需求，图案层可以通过打印获得，能够实现定制；
由于实木材质与聚烯烃材质的线性膨胀系数不一致，存在涨缩差异，导致两者之间易发生变形，实木层容易发生翘曲，上述方案通过平衡层来平衡基材层与实木层之间的涨缩差异，确保实木层与基材层之间连接的牢固度。
作为优选，所述平衡层在平衡连接网上涂覆粘胶剂而形成，平衡层采用平衡连接网结合粘胶剂的方式，既能保持实木层与基材层纵向上连接力，又能增强横向上的连接力，综合提供理想的连接牢固度。
粘胶剂采用木材采用的粘胶剂，例如大豆胶或者酚醛胶等。

作为优选，所述NON-PVC基材层的主成分为聚烯烃和木粉。基材层的上述组成，所得的基材层的线性膨胀系数更接近实木，涨缩差异更小，相比单独使用聚烯烃，地板更不易翘曲变形。

进一步优选，聚烯烃和木粉的重量比为：4~5：2~4。
更进一步优选，聚烯烃和木粉的重量比为：5：2~3。

作为优选，所述白色UV漆层的表面设有相容剂层，所述相容剂层上设图案层。
进一步优选，相容剂层为20-30微米。
作为优选，所述凹凸效果层的表面设有UV面漆层。
进一步优选，UV面漆层的厚度略大于UV底漆层的厚度，约为80~100微米。
本发明还提供一种上述NON-PVC 3D打印室内地板的制备方法，包括如下步骤：
S-1.对NON-PVC基材层表面进行预处理，预处理后在NON-PVC基材层上铺设平衡层；所述预处理的具体操作为对NON-PVC基材层表面进行加热，并维持表面温度在42-56℃；
S-2.在平衡层上复合实木层，实木层表面涂覆UV底漆；
S-3.UV底漆干燥固化后涂覆白色UV漆，确保底色均匀一致，以免影响打印的整体效果；
S-4.待UV白漆固化干燥后，通过平板喷墨打印机打印出打印图案层，再在其上形成凹凸效果层，为达到耐磨的效果，之后在凹凸效果层上涂覆UV耐磨漆，得到地板。
作为优选，步骤S-4中凹凸效果层通过打印形成或者通过冲击形成。
作为优选，步骤S-3中的UV白漆层上辊涂相容剂后再通过平板喷墨打印机打印图案。
作为优选，步骤S-4中在制得图案层的表面涂覆UV耐磨漆，待UV干燥后，用平板喷墨打印机打印凹凸效果层，实现3D效果，由汞UV灯照射固化后涂覆UV面漆。
作为优选，步骤S-4中在UV白漆层上辊涂相容剂后，再通过平板喷墨打印机打印出图案层。
