- the balance adsorption layer 104 is made of a PVC tape, thereby overcoming the technical problem of the unequal tension between the upper layer and the lower layer, effectively compensating and balancing the tensile forces generated between each other.
- the equilibrium adsorption layer 104 is directly laid on the ground during installation, and forms several micro-vacuum regions with the ground to generate adsorption force.
- the vacuum zone is designed to simulate the design of an octopus sucker using bionics.

- Figure 2 The micro-vacuum region 107 is schematically illustrated by a hexagonal shape. Actually, as long as it is a line-closed geometry (whether or not it is regular), it can be used as the micro-vacuum region, and a circular shape can be preferably used as the micro-vacuum region for convenience of fabrication.

- the downward force will squeeze the micro-vacuum region 107 located below to partially or completely discharge the air in the small space of the region. Since the air in the micro-vacuum region 107 is discharged, the internal pressure is less than The atmospheric pressure is strong, thus producing an upward adsorption force. Since the equilibrium adsorption layer 104 is densely packed with thousands of tiny microvacuum regions 107, the adsorption force generated per unit area is sufficient to keep the floor blocks in a relative position after installation.
- P Absolute pressure The absolute vacuum in vacuum, the unit is: KPa (kPa)
- S suction cup area is the effective area of the suction cup, the unit is: cm2 (cm 2 ) If the S suction cup area is equal to 0. 16cm2, P absolute pressure is 50. 5, therefore micro vacuum
- the ideal adsorption force in the region is about 0.28 Kgf. It can be seen that the adsorption force of a single micro-vacuum region is not small, and a plurality of micro-vacuum regions are uniformly distributed in a unit area, and the adsorption force is sufficient to keep the relative position of the floor block and the ground from shifting.
- the floor block and the floor block may be misaligned or otherwise realized, and it is only necessary to ensure that there is no gap between the floor piece and the floor piece. Since the plastic floorboard is easy to process, it can be pre-machined into a square or rectangular shape depending on the place where it is laid. Even in order to achieve a special splicing pattern, the plastic floorboard can be machined into a circular or other profile.

Description
塑料地板块及其制造方法及利用其铺设而成的地板
技术领域
本发明涉及一种用于建筑物内部地面装修的材料，尤其涉及一种 塑料地板及其制造方法及利用其铺设而成的地板。 背景技术
塑料地板， 即用塑料作为主要材料的地面装饰材料。塑料地板以 其装饰性强、 脚感好、 轻便的优势， 克服了实木地板、 强化地板、 瓷 砖等传统地面材料的劣势， 一直以来深受国内外消费者的青睐。塑料 地板按其使用状态可分为块材 (或地板砖)和卷材 (或地板革)两种，其 中块状地板（或称地板块）便于运输和铺贴， 内部能够含有大量填料， 具有价格低廉、 耐烟头烧灼、 耐污染、 耐磨性好、 损坏后易于调换等 一系列优点。 现有技术中，铺设塑料地板块的方法一般是采用粘胶剂将地板粘 贴地面或者在地板与地板之间以不干胶连接，或者地板与地板之间以 卡扣方式连接铺设。胶水铺设的方式需要在铺设安装地板前增加一道 涂设胶水的工序， 既耗费人力有耗费时间， 而且增加胶水也容易导致 甲醛等有害人体的物质含量超标。而且利用胶水铺设地板， 随着使用 时间的增长， 胶水逐步老化以及本身地板所承受的张力不平衡， 地板 很容易发生脱胶起翘、 开裂、 拱起等现象。卡扣式塑料地板不仅生产 工艺复杂， 精度要求高， 而且遇潮湿环境同样会出现开裂、 起翘等问 题。
因此，急需要一种新的技术方案以解决现有技术中存在的诸多缺 陷。
发明内容
本发明的目的在于提供一种无需胶水安装的塑料地板块，同时该 塑料地板块还能克服容易开裂上翘或拱起的技术缺陷。
为了解决上述技术问题， 本发明公开一种塑料地板块， 包括图案 层、基材层，还包括一平衡吸附层，所述平衡吸附层直接与地面接触， 并且平衡吸附层上设有与地面产生吸附力的若干个微真空区域。
更进一步， 该塑料地板块还包括一 PVC层， 所述 PVC层位于所述 图案层上方。
该微真空区域由线条封闭的几何图形组成。该微真空区域均匀分 布，单个几何图形的直径小于等于 8mm。该微真空区域的形状是圆形。 该基材层至少由塑料、 碳酸钙、 增塑剂及铁粉组成。 该塑料的成分比 例为 20-40%, 所述碳酸钙的成分比例为 20-60%, 所述增塑剂的成分 比例为 7-20% , 所述铁粉的成分比例为 20-50%。 该平衡吸附层由 PVC 胶布组成。
本发明同时还公开一种塑料地板的制造方法， 包括： 将 PVC层、 图案层、基材层及 PVC胶布按从上至下的顺序设置； 将上述材料热压 后形成一个整体并在所述 PVC胶布上形成若干个微真空区域。
更进一步， 该基材层至少由塑料、 碳酸钙、 增塑剂及铁粉组成， 该塑料的成分比例为 20-40%, 该碳酸钙的成分比例为 20-60%, 该增 塑剂的成分比例为 7-20%, 该铁粉的成分比例为 20-50%。
本发明同时还公开一种利用该塑料地板块铺设而成的塑料地板。 与现有技术相比较，本发明所提供的技术方案无需使用胶水而能 够依靠自身的重力产生吸附力， 能够有效解决现有技术中所存在的
铺设工序繁杂， 易造成环境污染的技术问题； 同时该地板块还能克服 传统塑料地板块容易拱起、 上翘、 不能防潮等技术问题。
附图说明
图 1是本发明所涉及的塑料地板的结构示意图；
图 2是本发明所涉及的塑料地板的平衡吸附层的结构示意图； 图 3是本发明所涉及的塑料地板的工作原理图。
最佳实施例
下面结合附图和具体实施方式对本发明做进一步阐述。 本发明提供一种新型的塑料地板块，该地板块在铺设时不需要胶 水作为粘结工具。 该地板块被放置于地面上时， 直接与地面相接触， 并能依靠自身的重力产生吸附力，并且该地板块还能克服传统塑料地 板块容易拱起、 上翘、 不能防潮等技术问题。
如图 1所示， 图 1是本发明所涉及的塑料地板的结构示意图。从 图 1中可以看出， 该地板块由多层结构组成。 其中， PVC层 101是该 塑料地板的耐磨层，该耐磨层可以根据图案层的材料的选择或使用场 合的改变而作为可选择层使用。
图案层 102用于为地板提供变化丰富的各种花紋图形，该图案层 102通常由 PVC材料制成， 也可根据地板块适用场合的改变而选用其 他材质作为图案层 102。 图案 102以下则是为整个地板块提供支撑的 基材层 103。
传统的塑料地板块中，一般将增塑剂及碳酸钙作为填充剂加入其 中。 配制塑料时加入填充剂， 其目的是改善塑料的成型加工性能， 提 高制品的某些性能， 赋予塑料新的性能。增塑剂的功用是使塑料地板
的柔韧性增加， 易于弯折， 而碳酸钙的加入则使塑料制品的稳定性更 好。本发明所提供的基材层 103的组成成分， 除了上述两种普通的填 充剂以外还增加了铁粉。 由于铁粉的比重远超过塑料及碳酸钙， 因此 增加铁粉后本发明所提供的地板其比重也远大于普通塑料地板块。现 有技术中也使用石英砂作为大比重的填充剂，但是因为石英砂本身吸 水且比重比铁粉小，因此由石英砂制成的塑料地板不能防潮而且不能 产生足够的重力和吸附力。在基材层 103中增加铁粉， 不但使塑料稳 定性更好， 而且还能防水防潮。为了使本发明所涉及的地板块的技术 效果最佳， 即既满足稳定性强、 柔韧性佳、 比重大、 防水防潮等技术 特点， 基材层 103 中各材料的成分比例大约为塑料 20-40%, 碳酸钙 20-60%, 增塑剂 7-20%, 铁粉 20-50%。
由于基材层 103中除了塑料还添加了其他物质，因此基材层的塑 料所占的总比重远远小于耐磨层 101和图案层 102， 因此基材层 103 和耐磨层 101及图案层 102各自的张力不一致，也因此彼此之间所产 生的拉力不对等， 时间一长地板块就容易蜷曲、 拱起或变形。 为了进 一步解决该技术问题， 在基材层 103下面设置一平衡吸附层 104。 该 平衡吸附层 104由 PVC胶布制成，因此克服了上层与下层之间拉力不 对等的技术问题， 有效地弥补和平衡了彼此之间所产生的拉力。
同时该平衡吸附层 104在安装时直接铺设在地面上，并与地面形 成若干个微真空区域以产生吸附力。该真空区的设计是利用仿生学模 拟章鱼吸盘的设计。如图 2所示， 图 2是平衡吸附层 104与地面接触 的一面上布满了无数的一个接一个的小型的微真空区域 107。 图 2中
该微真空区域 107是以六边形作为示意性说明，实际上只要是线条封 闭的几何图形（无论是否规则）均可作为该微真空区域， 为了制作方 便可以优选圆形作为该微真空区域。
如图 3中所示， 图 3是本发明所涉及的塑料地板的工作原理图， 也是该吸附力产生的原理图。基材层 103位于平衡吸附层 104的上方， 平衡吸附层 104上布满了无数个微真空区域 107， 该平衡吸附层直接 紧贴地面 105。 当本发明所提供的地板块被安装时， 不需要胶水， 只 需要将地板块放于地面上即可。如图 3所示， 由于基材层 103的特殊 设计， 使其重量是普通地板块的数倍， 因此由基材层 103的自重会产 生一个向下的力。该向下的力在安装的一瞬间， 会挤压位于下方的微 真空区域 107使该区域的小空间内的空气部分或全部被排出，由于微 真空区域 107内空气被排出， 其内部压强小于大气压强， 因此产生一 个向上的吸附力。由于该平衡吸附层 104上布满密密麻麻成千上万个 微小的微真空区域 107， 因此单位面积内产生的吸附力足以使地板块 在安装后保持相对位置的不变。
真空的吸附力计算公式为：
F^O. 01 X ( 101— P绝对压力） X S吸盘面积
上式中，
F: 理论吸附力大小， 单位： Kgf (公斤力）
P绝对压力： 为真空内的绝对真空度， 单位取： KPa (千帕） S吸盘面积： 为吸盘有效面积， 单位取： cm2 (平方厘米） 假如 S吸盘面积等于 0. 16cm2， P绝对压力为 50. 5， 因此微真空
区域内的理想吸附力约为 0. 28 Kgf。 由此可见， 单个微真空区域的 吸附力已经不小， 而单位面积内均匀分布着若干个微真空区域， 其吸 附力足以保持地板块与地面的相对位置不发生偏移。
由该塑料地板块铺设地板的过程中，地板块与地板块之间错位或 以其他方式均可以实现，只需保证地板块与地板块相互之间没有缝隙 即可。该塑料地板块由于其加工简易方便， 因此可根据铺设的场合不 同将其预先加工为正方形或矩形的形状。甚至， 为了实现特殊的拼接 花紋， 可以将该塑料地板块加工成圆形或其他异形。
在该地板块的使用过程中， 即该地板块铺设完成后， 由于人们在 地板块上行走往来， 因此持续不断地挤压空气， 形成一个又一个的微 真空， 因此无论使用多久， 都不会发生卷曲、 拱起的现象。 在铺设时 除了可以直接铺设于地面上外，还可以通过在地表洒水或洒其他液体 的方式增加吸附力。
本发明同时提供一种塑料地板的制造方法， 该塑料地板在制造 时， 首先将 PVC层、 图案层、 基材层及 PVC胶布按从上至下的顺序设 置， 然后利用热压机将上述四种材料热压成型， 在热压成型的过程中 同时可以利用模具在 PVC胶布上热压形成若干均匀分布的线条封闭 的几何图形作为真空吸附区。基材层由塑料、 碳酸钙、 增塑剂及铁粉 组成， 该塑料的成分比例为 20-40%, 该碳酸钙的成分比例为 20-60%, 该增塑剂的成分比例为 7-20%, 该铁粉的成分比例为 20-50%。
工业实用性
由于本发明是在现有技术上的改进，在现有的塑料地板上增设一 平衡吸附层，该平衡吸附层不但能够增强该塑料地板与地面形成的吸
附力， 还能防止地板开裂上翘或拱起， 这样不但可以克服了现有技术 的不足， 而且可以适用于工业上的大量生产。
