Description

一种实木复合地板 技术领域
本技术涉及实木复合地板。
背景技术
当前，室内外铺装的实木复合地板通常包括三层实木复合地板或者多层实木复合地板。
三层实木复合地板一般有表层、芯层和底层组成，芯层多为实木木条，由于实木木条对于木材的利用率相对较低，且芯层的拼接增加了额外的工序，且实木木条的生产过程比较复杂，一般包括原木剖方、截断、切板、干燥等步骤。另外，翘曲度较大，不平整，而且因为只有三层结构，表层木材纤维方向地板一般要平行于地板长度方向，而芯层与表层交错组坯，所以芯层木材纤维方向是垂直于地板长度方向的。这样，开在芯层两侧的沿地板长度方向延伸的榫槽只能与芯层木材纤维方向垂直，榫槽表面不光滑，视觉上不美观，而开在芯层两端的沿地板宽度方向延伸的榫头与木材纤维方向平行，且长度较小，因而两端的榫头能承受的力较小，地板容易损坏，通常需要额外增加榫头板来解决。
多层实木复合地板一般也是由表层、芯层和底层组成，芯层多为多层胶合板(4层以上)。多层胶合板一般用2mm以下的旋切单板胶合层压而成，层数多，胶水使用量大，环保性有待提高；多层胶合板开槽后，企口或者锁扣处非常粗糙，视觉很不美观；由于胶水使用量大，胶线多，开榫头和榫槽时极大缩短了刀具的利用率和使用寿命，从而增加额外的加工成本。
发明内容
本技术的目的是提供一种生产效率高、质量稳定、地板变形小、翘曲度低、表面美观无毛刺、施胶量少、成本低的实木复合地板。
一种实木复合地板，包括表层、次表结构层、芯层、底层结构层及防变形对称底层五层结构，所述表层为薄木或浸渍纸，次表结构层和底层结构层为旋切单板，芯层为旋切木材层，防变形对称底层为浸渍纸或薄木。
上述的实木复合地板，作为表层的薄木外表面具有涂饰层。薄木外表面的涂饰层如清漆，具有装饰作用，同时可以提高耐磨性。
上述的实木复合地板，作为表层的薄木厚度为0.2-2.5mm。
上述的实木复合地板，次表结构层和底层结构层厚度均为2-6mm。
上述的实木复合地板，芯层厚度为5-14mm。
上述的实木复合地板，作为防变型对称底层的薄木厚度为0.2-2mm。
上述的实木复合地板，次表结构层和底层结构层的材质密度为0.5-1.0g/cm3，且大于芯层的材质密度。例如：次表结构层和底层结构层为杉木、桉木等偏硬树种，芯层为松木、杨木等偏软树种。
上述的实木复合地板，芯层木材的纤维方向平行于地板长度方向，芯层的四边开榫头和榫槽。
本实用新型的有益效果：由于采用了厚旋切木材层(5mm-14mm)作为芯层，而摒弃了常用的以实木木条或者多层胶合板作为芯层的结构，所以在制备芯层时，对原木截得的木段旋切制得旋切木材即可，加工方便，制备快捷，降低了实木复合地板的生产成本。采用基本对称的五层结构，地板变形小，翘曲度低。次表结构层和底层结构层作为结构层，对芯层起到了压紧作用，提高了地板的整体强度。以浸渍纸或薄木作为表层或者防变形对称底层，外形美观。次表结构层和底层结构层的材质密度大于芯层的的材质密度，对芯层起到了束缚，防止了芯层的变形，提高了地板的平整度。芯层木材的纤维方向平行于地板长度方向，开在芯层两侧沿地板长度方向延伸的榫槽或者锁扣平行于芯层木材的纤维方向，榫槽表面光滑，无毛刺；开在芯层两侧沿地板宽度方向延伸的榫槽能够承受较大的力。同时，厚芯旋切木材层的使用可有效降低实木复合地板的施胶量，可延长地板在后期加工过程中刀具的使用寿命而节约成本。
附图说明
图1是实木复合地板的截面示意图。
具体实施方式
下面结合附图和具体实施方式对本实用新型作进一步说明。
实施例1：
参见图1所示实木复合地板，包括表层1、次表层结构层2、芯层3、底层结构层4及防变形对称底层5。表层为厚度约0.6mm的刨切薄木，次表层结构层为3.5mm桉木单板，芯层为8mm旋切松木单板、底层结构层为3.5mm桉木单板，防变型对称底层为浸渍纸。
芯层木材纤维方向平行于地板的长度方向，在芯层的四边分别开有榫头31和槽口32。
该实木复合地板在长度方向的翘曲度不超过1％，宽度方向翘曲度不超过0.3％。
表层为薄木、浸渍纸后者或者具有涂饰层的薄木，一方面可以起到装饰的作用，赋予实木复合地板的外观特性，另一方面，可以通过涂饰层或浸渍纸装饰起到表面耐磨的作用，提高地板的使用寿命。
防变形对称底层一方面可以平衡表层薄木在木材干缩湿胀过程中的张缩力，另一方面，浸渍纸的使用可以减少水分从实木复合地板底部进入板体内部道，从而提高实木复合地板的尺寸稳定性的作用。
