Description

塑料地板块及其加工方法及利用其铺设而成的地板
技术领域
本发明涉及一种塑料地板及加工方法，尤其涉及一种具有自助安 装功能的塑料地板。
背景技术 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。但随着塑料地板被日益广泛的使用， 其缺点也越来越多的显 现出来。传统的带胶或不带胶地板受地面基材的限制暴露出与地面接 触差、 胶水有机物的挥发、 铺装复杂、 施工耗费较多的人力、 使用后 不易拆除和重复使用的劣势。还有一类组合地板， 不论是锁扣结构或 凹凸插口结构， 都存在加工工序复杂、 加工精度要求高， 铺装拆装繁 琐、资源浪费大的不足， 在使用过程中还可能因为结构组合的公差问 题影响产品的美观， 比如中国发明专利申请公布说明书， 公开号为
CN101029534A, 名称为聚氯乙烯地砖及其铺装方法， 该专利是在地板 砖的底料层上加工出凹部与凸部， 不但加工复杂， 而且由于加工精度 要求高， 容易影响产品组合后的美观。
另外， 已上市的一种易拼接悬浮结构的塑料地板（比如本申请人 已经授权的实用新型专利， 授权公开号： CN2791155Y,名称： 易拼接 塑料地板）， 虽然在很大程度上解决了上述遇到的种种问题， 然而在 使用过程中这种易拼接悬浮结构的塑料地板易产生热熔胶受水分湿 度或胶本身粘性强度的影响而脱胶开裂的现象。再者， 这种易拼接悬 浮结构的塑料地板铺装完后是一整体，因塑料的热胀冷缩特性会造成 积累的膨胀或收缩现象，因而不利于在环境温度变化较大或铺装面积 较大的场合使用。 这是此结构难以克服的缺陷。
发明内容 本发明所要解决的技术问题是提供一种塑料地板块，它可以在不 增加生产工序的情况下， 优化生产工艺， 实现塑料地板的拼装、拆装 简易化， 并使塑料地板真正可以反复使用， 大大降低了使用成本， 特 别是通过优化产品结构， 降低了塑料热胀冷缩对地板的影响程度， 使 塑料地板更加美观实用。另外还提供了一种地板块的加工方法， 同时 可以解决上述问题。 并且还提供了根据上述地板块形成的一种地板。
为了解决以上技术问题，本发明提供了一种塑料地板块，它由上、 中、 下三层塑料地板块复合而成， 其中， 中间层与上、 下两层同向错 位， 在中间层位置形成凸起和凹槽， 所述上、 中、 下三层塑料地板块 的每层均至少包括底料层。
所述上层地板块设有带图案的面层，所述下层地板块也设有带图 案的面层。
另外， 本发明还提供一种地板块加工方法， 第一歩， 选取三块塑 料地板块； 第二歩， 将三块塑料地板块分上、 中、 下三层错位复合而 成， 同时在中间层位置形成凹槽和凸起。
另外， 本发明还提供了一种地板， 所述地板有多个所述的地板块 组合而成，相邻地板块之间通过其中一块地板块的凸起和相邻另一块 地板块的凹槽插合连接。
因为本发明地板块为三层独立的地板块叠加错位成形， 自动形成 了凹槽和凸起， 并且由于所述凹槽和凸起均为中间层形成， 因此其大 小可以自动匹配， 这样在生产工艺中一次成型， 减少生产工序， 节约 资源能源。另外， 本发明地板在施工中拼装、拆装简单， 可重复使用。 还有， 可以在上下层地板块面均设有带图案的面层， 也就形成了双面 型地板， 这样也就给客户多一种选择， 且产品自然形成装饰嵌条的铺 装效果。

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歩阐述。 图 1 是本发明塑料地板块的结构示意图。 本发明塑料地板块由 上、 中、 下三层独立的塑料地板块 1、 2、 3复合而成， 其中， 中间层 地板块 2与上层地板块 1、 下层地板块 3同向错位， 在中间层地板块 2位置形成凸起 4和凹槽 5 ; 结合附图 2可以看出， 三者之间是独立 的三层塑料地板块，当然这三层塑料地板块的每层均可以是完整的地 板块，所谓完整的地板块也就是同时包含有耐磨层、印刷层和底料层， 也可以是其中一层或两层是为完整的地板块，比如仅仅上层地板块块 为完整的地板块， 这也是目前普通的地板的样式。相对于现有技术不 同的是， 本发明可以采取上下两层均为完整的地板块， 也就是可以实 现双面使用。
当然这里的塑料地板块， 尤其是上下两层， 可以不是所谓的完整 的地板块， 只要设有带图案的面层（相对于现有技术中的印刷层）即 可， 也就是满足美观需要而已， 所谓的完整的地板块的定义不是用于 限定， 而只是一个说明现有的单个地板块的形式， 因此本发明的带图 案的面层可以类似于现有技术中的印刷层或类似定义即可。当然在上 下层均带有面层时， 面层应当是位于塑料地板块的上下面。
当然也不排除一种特殊情况， 就是上、 中、 下三层地板块 1、 2、 3均只包括底料层， 这也是本发明的最低要求， 就是三者最少包括底 料层， 为什么必须这样要求呢， 主要在于， 底料层具有一定厚度， 三 者的结合可以自然形成本发明需要的凸起 4和凹槽 5， 因此这里的底 料层的定义和含义也是一种相对开放的，只要具有一定厚度的塑料层 或类似或可以替代的层即可， 当然也可以采取多层叠加， 但只要目的 和结构起到相同或类似作用， 均在本发明保护范围。
关于三层塑料地板块的大小问题， 当然厚度本身可以不同， 但中 间层地板块 2的厚度有一定要求， 就是要满足能够基本连接需要， 当 然这个厚度多少合适， 根据实际需要设定。这主要在于本发明的凸起 4的厚度就是中间层地板块 2的厚度， 同时凹槽 5的宽度也是中间层 地板块 2的厚度。
而三层地板块的长宽可以是完全一样， 当然理想的方式是， 如果 是单面， 也就是只有上层地板块带有图案面层的情况下， 上层地板块 1长宽略大于中间层地板块 2和下层地板块 3， 或者上下层地板块 1、 3均大于中间层地板块 2。 当然也不排除中间层地板块 2的长宽略大 于上层地板块 1的长宽， 或大于下层地板块 2的长宽， 或者同时大于 上下层地板块 1、 3的长宽。
当然在下层地板块的端部可以刻有刻沟，本文所指的刻沟是指除 去面层， 露出底料层， 因此刻沟应当是很浅的沟痕， 这样从表面看象 是嵌条一样， 主要起到装饰作用。这样在双面使用时， 下层地板块将 作为上层使用，此时由于刻沟处的露出的颜色（一般是底料层的颜色) 不同于下层地板块的面层颜色， 这样在组合形成的地板中间， 刻沟可 以起到类似于嵌条的作用。当然这里的端部一般而言是指下层地板位 于凹槽一侧的相邻两边的端部， 即形成 L形刻沟。
三层塑料地板块可以采用热熔压敏胶经专有设备粘合而成， 当然 也可以采取类似手段， 因此三者形成的地板块为一体成型的整体结 构。 另外， 在上下层地板块 1、 3可以同时涂有热熔压敏胶， 当然应 当是上层地板块 1的下面 6和下层地板块 3的上面 7， 因为这主要用 于粘结，另外这样做的一个好处在于形成的凹槽 5中也同时具有了上 述热熔压敏胶， 而不需要另外涂抹， 这样在两片地板块扣和时， 凹槽 和凸起之间就有胶合粘结， 增强了连接力度。 当然也可以仅仅在中间 层地板块 2的上下面均涂上热熔压敏胶。
如图 3所示， 它是图 1中 A部的放大示意图。在图 3中可以更清 晰地看出凹槽 5的结构， 同时也可以看到在位于凹槽 5的一侧， 在上 层地板块 1上形成有倒角 9， 在下层地板块 3上形成有倒角 8。 这里 的倒角 8、 9主要用于后续组合时起到导向作用， 比如图 5中两块地 板块组合时， 倒角 8、 9主要可以顺利地将凸起 4导入到凹槽 5中。 当然也可以将凸起 4进行倒角处理， 这样也可以起到导向作用。 关于中间层地板块 2与上层地板块 1、 下层地板块 3同向错位， 是指中间层地板块 2在同一个水平面与上层地板块 1、 下层地板块 3 在同一个方向错位， 这样才能形成同时形成凸起 4和凹槽 5。 当然是 否完全一致也不是一定要这样， 理想状态是完全一致最好， 当然也排 除特殊情况下不一完全一致更好的情形。 而对于后续形成的地板而 言， 关键地是每块塑料地板块错位一致即可。
图 4以及图 4A、 4B、 4C是本发明各方向视图， 通过这些视图可 以看出， 中间层地板块 2与所述上、 下层地板块 1、 3呈 L形错位， 比较明显的是凸起 4相对于地板块而言呈 L形，当然与此同时形成的 凹槽 5也是 L形。 当然 L形错位是一种比较理想的方式， 当然也可以 采取类似错位， 之所以要求 L形错位， 主要在于 L形错位可以实现在 长宽两个方向均有错位， 这样每片地板块可以实现在四周连接， 因此 能够实现类似功能的类似结构都可以。上述 L形错位主要在于三层地 板块均为方形地板块， 如果三层地板块采取其它规则或不规则形状 时， 则可以采取与之对应的错位形状， 尤其考虑中间层的形状。
本发明地板就是根据本发明地板块组合而成的，相邻地板块之间 通过其中一块地板块的凸起和相邻另一块地板块的凹槽插合连接。如 图 5所示， 它是两块地板块组合示意图， 其中地板块 101不动， 地板 块 102向地板块 101方向运动，然后将地板块 102的凸起插入到地板 块 101的凹槽中组合起来。
而图 6、 7是六块地板块组合而成的结构示意图， 其中通过图 7 可以看出组合之间的关系， 从图中可以看出有六块地板块 103、 104、 105、 106、 107、 108组成， 其中纵向铺设有地板块 103、 104、 105， 横向铺设有地板块 103、 106、 107、 108。 当然图中所示位置是一种 理想方式， 在实际铺设时， 地板块 104、 105与地板块 103是错位的， 比如地板块 104、 105可能同时与地板块 103、 107组合， 或者同时与 地板块 103、 106组合； 或者地板块 104与地板块 103、 107组合， 而 地板块 105与地板块 103、 106组合， 这样做的目的主要在于抵压横 向地板块之间的接触缝隙， 比如地板块 104与地板块 103、 107组合， 地板块 104可以抵压地板块 103、 107之间的接触缝隙， 这样可以加 强组合强度。 图 8是图 6中的 B部放大示意图。通过图 8就可以更清晰地看出 组合的情况， 其中第一块由上层地板块 11、 下层地板块 31以及中间 层地板块 21复合而成， 第二块由上层地板块 12、 下层地板块 32以 及中间层地板块 22复合而成， 其中第一块形成有凹槽 5以及倒角 8、 9， 第二块形成有凸起 4， 二者组合后的形状就如图 8所示， 凸起 4 插入在凹槽 5中， 上层地板块 11、 12抵靠在一起， 下层地板块 31、 32有错开。 当作为双面地板使用时， 可以在下层地板块 31的端部， 也就是靠近下层地板块 32处刻沟，这样从外部看，在下层地板块 31、 32 之间表面形成有类似嵌条一样的刻沟， 这样就可以掩盖了下层地 板块 31、 32之间的很小的缝隙。
本发明的地板块为什么操作方便呢， 和现有技术对比就可以知 道， 比如中国发明专利申请公布说明书， 公开号为 CN101029534A , 名称为聚氯乙烯地砖及其铺装方法的专利， 也是采取类似的结构， 但 由于凹部和凸部是加工形成的， 这样的结构不易控制， 而本发明的凹 槽的宽度和凸起的厚度均是由中间层形成的，因此只要中间层的厚度 一致， 基本上就可以控制了整个地板块之间的配合了， 当然做到这一 点非常容易， 没有特别的加工精度要求。
另外， 本发明和上述现有技术相比而言， 由于采取独立的三层地 板块复合而成， 不但加工简单， 而且各种配合很容易控制。
因此要求每个地板块大小相匹配， 每个塑料地板块的错位相同， 所述每个塑料地板块的相对应的三层大小一致就可以了。当然略有不 同也不会影响到使用， 甚至故意完全不同， 也同样可以起到标新立异 的效果。
并且实现每个地板块大小匹配，只要每个地板块的加工工艺和选 材均按照本发明的地板块的形成方法制成即可。即首先， 选取三块塑 料地板块； 其次，将三块塑料地板块分上、中、下三层错位复合而成， 同时在中间层位置形成凹槽和凸起， 其中中间层与上下层为同向错 位。
另外， 还有一个问题， 就是附图中上、 中、 下三层地板块 1、 2、 3的材质一般而言， 采用相同的材质， 当然也可以根据具体情况选用 具有兼容性的材质。虽然附图中的三层采用不同的纹理标注， 它只是 为了示意不同的层， 而不是表明材质不同。
还有就是为了防止热胀冷缩， 可以分别在上下层地板块 1、 3上 进行刻沟线， 当然为了美观需要， 一般而言是在上层地板块 1的下面 6以及下层地板块 3的上面 7进行刻沟线。
工业实用性
由于本发明是在现有技术上的改进，将现有三个独立的塑料地板 块复合而成， 并且该复合而成的地板自动形成的凹槽和凸起， 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。
