Description
技术领域
本发明涉及一种地板,更具体而言,涉及一种可易于提供手工效果以增强地板的天然表面纹理并且可防压、防划痕和防变色等的地板。
背景技术
一般而言,铺设地板是为了覆盖和装饰铺设在建筑物室内地板上的混凝土表面,从而呈现高档的室内环境并提供天然木材纹理的效果。
随着胶合板生产技术的发展,对硬木的使用已增加,并且,能够提供各种具有良好性能的胶合板。胶合板通过以下步骤生产:将硬木磨薄,而非直接将硬木切割成木料或板材;切割所述薄木板;以木纹彼此成直角排列的方式层压薄板;用粘合剂粘合薄板以形成预定厚度的板体。
通过上述步骤生产的胶合板不易变形,这是因为,与具有纹理的木板相比,其纹理方向不同,并且,通过上述步骤生产的胶合板能够提供增加的各个方向的公差。然而,所述胶合板的问题在于,由于其因生产方法的特点而不具有图案,例如木纹,因而装饰性能差。
因此,为了将胶合板用于地板或其他建筑材料,对胶合板的表面进行装饰以具有类似于平切单板(sliced veneer)的图案,并用树脂清漆涂覆胶合板,从而具有耐水性和耐划痕性。
作为所述地板的生产方法的实例,有这样一种生产地板的方法:通过使用尿素树脂将装饰性单板粘合在胶合板的上表面上而生产木板,但所述木板生产方法的缺点在于,生产成本增加且耐水性和耐热性非常差。
此外,使用木材的地板能够提供手工效果以确保真实性,但却难以确保生产率,原因在于手工效果是通过手工劳动实现的。特别是,木板存在若干问题,所述问题在于,使用通常使用的0.5mm的平切单板难以呈现手工效果,还在于生产成本增加,因为要使用至少2mm的硬木。
发明内容
技术问题
因此,本发明致力于解决现有技术中存在的上述问题,且本发明的目的在于,提供一种地板,所述地板可使用PLA(聚乳酸)树脂而非木材形成层压在基层上面的表层,从而能够确保环境友好,可通过在生产表层时使用压花辊在表层的表面上施用弯曲图案而容易地提供手工表面纹理,并且,与木材相比,可防压、防刮痕、防变色等。
技术方案
为了实现上述目的,本发明提供一种地板,所述地板铺设在建筑物的地面上,所述地板包括:由MDF、HDF和胶合板之一制成的基层;和具有依次层压在基层上面的增强层、印刷层和透明层的表层,所述增强层、印刷层和透明层的至少一层由PLA(聚乳酸)树脂制成,其中,弯曲图案形成于表层的上面。
所述地板通过在表层上面形成弯曲图案而提供手工表面纹理。
此情况下,弯曲图案通过使表层通过一对压花辊之间的压制法形成,所述压花辊通过接收发动机供给的驱动力旋转。
此外,至少一个压花辊具有布置于其外周表面上的预定形状的凸起部件,以通过压制表层的一侧形成弯曲图案。
此外,表层通过一种热固性三聚氰胺树脂的粘合层作为介质层压在基层的上面。
此外,表层包括层压在其上表面上的UV涂层。
此外,地板还包括置于基层下部的平衡层,所述平衡层用于对地板的上部和下部的卷曲保持平衡。
有益效果
本发明的地板可使用PLA(聚乳酸)树脂而非木材形成层压在基层上面的表层,从而确保环境友好并降低生产成本,可通过在生产表层时使用压花辊在表层上施用弯曲图案而容易地提供手工表面纹理,并且,与木材相比,可防压、防刮痕、防变色等,从而确保良好的表面性能。
附图说明
图1为本发明地板的截面视图。
图2为示出本发明地板的弯曲图案的照片。
图3为示出用于形成弯曲图案的压制设备的照片。
图4为示出一对置于压制设备上的压花辊的照片。
具体实施方式
将参考附图详细阐述本发明的优选实施方案。
在附图中,即使相同的部件示于不同的图中,其附图标记也是相同的。
图1为本发明地板的截面视图,图2为示出本发明地板的弯曲图案的照片。
参考图1和图2,本发明优选实施方案的地板100铺设在建筑物的地面上,且包括:基层110;和具有依次层压在基层110上面的增强层131、印刷层133和透明层135的表层130,所述增强层131、印刷层133和透明层135的至少一层由PLA(聚乳酸)树脂制成。弯曲图案137形成于表层130的上面。
本文中,优选弯曲图案137通过如下方法形成:在将表层130通过一对旋转的压花辊(R)之后,压制表层130。(参见图3)
此情况下,一对压花辊(R)彼此之间保持预定的间隔,从而以预定的压力形成弯曲图案137,而不是以一个方向加压来碾压表层130的上面。此外,至少一个压花辊(R)具有布置于其外周表面上的预定形状的凸起(R1),以通过压制表层130的一侧形成弯曲图案137。本文中,凸起(R1)优选形成于上辊上。(参见图4)
压花辊(R)沿着放置在一侧的表层130的上面的纵向方向反复形成弯曲图案137,同时通过接收置于压花辊(R)的一侧的发动机(图中未示出)供给的驱动力以预定速度旋转。
同时,基层110提供地板的大部分预定厚度。所述基层110可由MDF(中密度纤维板)、HDF(高密度纤维板)和胶合板之一制成。众所周知,MDF和HDF通过如下步骤生产:将硬木磨成粉末;将胶混合至粉末并将混合物聚集成块;以及将混合物压制成板例如胶合板。
更具体而言,由于MDF在整个厚度具有均匀的纤维分布和致密的纹理,因此适于复杂的机械加工,且所述复杂机械加工的实施不破坏表面或侧面。此外,MDF非常适合于覆盖或印刷装饰膜或单板,原因在于,MDF具有坚硬且光滑的表面。此外,MDF还用作抽屉侧面、柜子的滑轨、镜框、模塑物和地板用的材料。
HDF广泛用作胶合板的替代品、家具材料和层压地板,原因在于其密度为900kg/m且强度高于MDF。
此外,表层130的PLA(聚乳酸)树脂为丙交酯或乳酸热塑性聚酯,且可通过使乳酸聚合而制备,所述乳酸通过发酵提取自玉米、马铃薯或其他物质的淀粉制备。
所述PLA树脂的优点在于,其可以解决因消耗油资源而产生的问题,因为其是可再生的,还在于,PLA树脂对环境有害的材料的释放量仍然较低且可比其他树脂例如氯乙烯更加快速地降解。
PLA树脂可分为结晶PLA(c-PLA)树脂和无定型PLA(a-PLA)树脂。由于结晶PLA可造成增塑剂流出片材表面的渗出,因此本发明使用无定型PLA树脂。
优选使用100%无定型PLA树脂,但根据场合需要,也可使用具有结晶和无定型结构的PLA树脂。
此外,PLA树脂可含有用于形成丙烯酸共聚物的非邻苯二甲酸酯基增塑剂、碳酸钙、硅胶和二氧化钛作为填料,以增加熔体强度。此情况下,增塑剂为用于根据使用目的而提供物理性能的添加剂,所述物理性能例如加工性、柔性及其他性能,且在本发明中,使用对人体无害的非邻苯二甲酸酯基增塑剂。
具有上述材料和结构的表层130通过一种热固性三聚氰胺树脂的粘合层100作为介质层压在基层110的上面。
此外,UV涂层139层压在表层130的上面,用于保护表层130,以通过与木材相比防压、防划痕、防变色等确保良好的表面性能。
此外,地板还可包括置于基层110下部的平衡层(图中未示出),所述平衡层用于对地板100的上部和下部的卷曲保持平衡。
如上所述,本发明的地板100可通过形成的弯曲图案137而提供表面纹理,所述表面纹理看上去像是工人使用例如刨等工具把地板表层130的表面磨光,所述弯曲图案137通过在将表层130通过旋转的压花辊(R)之后,对表层130进行压制形成,因此,本发明的地板100可向使用地板100的消费者提供手工的美感。
虽然参考本发明的优选实施方案具体呈现并描述了本发明,但是,本领域普通技术人员应理解,本发明并非限于上述实施方案,而是可在不偏离本发明的技术主旨的前提下作出各种变化。
