本发明涉及塑料地板领域技术，尤其是指一种具有较高止滑系数的PVC止滑地砖及其制备方法。
背景技术
众所周知，以高分子化合物(树脂为主要原料)所制成的地板覆盖材料称为塑料地板。它有以下特点：(1)价格适度与地毯、木质地板，石材和陶瓷地面材料相比，其价格相对便宜。(2)装饰效果好：其品种、花样、图案、色彩、质地、形状的多样化，表面为高密度特殊结构，能满足不同人群的爱好和各种用途的需要，如仿真木纹/大理石纹/地毯纹/花岗岩等纹路，模仿天然材料，十分逼真。(3)兼具多种功能：足感舒适，有暖感，能隔热、隔音、隔潮。(4)施工铺设方便，无需水泥沙子，不需要兴木动土，专用胶浆铺贴、快速简便；消费者更可亲自参与整体构思，选材和铺设。(5)施工重量轻，比木地板施工后重量轻10倍，比瓷砖施工后重量轻20倍，比石材施工后重量轻25倍，最适合三层以上之高建筑物、办公大楼等实用,减低其大楼的承重量，安全有保证，且搬运方便。(5)易于保养：易擦，易洗，易干，耐磨性好，使用寿命长。由此可见，塑料地板虽具有诸多特点和优势，具有广阔的市场前景。
在塑料地板中，止滑性能一值是业内不断研究与攻坚的重要课题之一。止滑性能是指塑料地板的防滑能力，止滑系数的大小是其止滑性能高低的重要指标。目前，曾有人提出一种在塑料地板与地面接触的底面上设置止滑纹路的设计，其止滑纹路多样，有正六边形、圆形或波浪形等。但是，这些纹路设计与组合不尽合理，导致塑料地板之止滑系数仍然较低，现有塑料地板的止滑系数只能达到1.1而已，而无法进一步提升，成为塑料地砖业内的一大瓶颈。
发明内容
本发明的主要目的是提供一种免胶PVC止滑地砖及其制备方法，其具有更优异之止滑性能。
为实现上述目的，本发明采用如下之技术方案：
一种环状结构的免胶PVC止滑地砖，包括自下而上依次叠层热压复合在一起的PVC止滑层、PVC底料层、PVC中料层、PVC印刷层和PVC耐磨层，该PVC止滑层之与地面接触的底面上热压形成有柔性热压纹路，该热压纹路包括连续重复连接的复数个封闭非等边六边形凸肋，由各非等边六边形凸肋围构出一封闭凹腔式吸盘；
其中，该PVC止滑层的材料配方为：按重量份计，包含：聚合度1000的PVC58.5%～63.5%、增塑剂34.9～39%、稳定剂0.95%～2.1%、色粉0.5%～0.69%、800目的碳酸钙0.06%～0.08%，前述物质总量之和为100%；
以及，该非等边六边形凸肋的形状与尺寸大小为：由两条等长平行的正短边和四条两两平行等长的斜长边围构形成，该各正短边的边长是4～8mm，各斜长边的边长是5～9mm，并其该斜长边的长度一定大于该正短边的长度，正短边和斜长边的宽度相同均是1mm、高度也相同均是0.25～0.35mm。
前述免胶PVC止滑地砖的制备方法，包括下述步骤：
（一）首次热压组合工序：将PVC止滑层、PVC底料层和PVC中料层自下而上依次叠放后热压贴合成一支撑体；热压时，加热温度为130℃/24分钟，热压过程采用分段式加压：第一段压力50-60kgf/cm2，时间24-27分钟；第二段压力60-80kgf/cm2，时间1-3分钟；第三段压力110-130kgf/cm2，时间15-20分钟；
（二）二次热压纹路工序：将PVC耐磨层和PVC印刷层自上而下依次叠置于前述支撑体上进行热压，热压时，加热温度为130℃/24分钟，热压过程采用分段式加压：第一段压力50-60kgf/cm2，时间24-27分钟；第二段压力65-95kgf/cm2，时间1-3分钟；第三段压力110-140kgf/cm2，时间20-24分钟；热压的过程中，PVC耐磨层与PVC印刷层复合，PVC印刷层与支撑体中的PVC中料层复合，同时于PVC止滑层底面和耐磨层的顶面热压出纹路；其中PVC止滑层之底面上的热压纹路为连续重复连接的复数个封闭非等边六边形凸肋；该非等边六边形凸肋的形状与尺寸为：由两条等长平行的正短边和四条两两平行等长的斜长边围构形成，该各正短边的边长是4～8mm，各斜长边的边长是5～9mm，并其该斜长边的长度大于该正短边的长度，正短边和斜长边的宽度均是1mm，高度均是0.25～0.35mm。
本申请人经过深入研究和无数次的试验后发现，止滑层的柔软性、止滑纹路的形状设计等多重因素组合决定着其止滑性能，唯有在这些因素得到最佳之组合时，产品的止滑系数才会最高。采用本发明之技术方案，其利用止滑层的特殊配方用量获得所需之柔软度，并结合该特殊大小、形状的非等边六边形止滑纹路，是止滑层之柔软性和止滑纹路形状的最佳结合，使其止滑系数可达1.5以上，较传统地砖的止滑系数1.1提高了36%以上，攻克了塑料地砖业内之止滑性能提升的瓶颈。以及，本发明在潮湿地面仍保持优良的止滑性能，而更适合于潮湿地面使用，例如浴室、阳台，易安装方便拆卸，遇水愈涩、不滑，大大提升了塑料地砖的止滑效果，从而使家居铺装可解除老年人及儿童的安全顾虑。
