Description

含茶生物活性成分的大生物石塑地板
技术领域
本发明涉及石塑地板制备技术领域，尤其涉及一种含茶生物活性成分的大生物石塑地板。
背景技术
石塑地板又称之为石塑地砖，是"PVC片材地板"的简称。石塑地板是一种高品质、高科技研究开发出来的新型地面装饰材料，采用天然的大理石粉构成高密度、高纤维网状结构的坚实基层，表面覆以超强耐磨的高分子PVC耐磨层，经上百道工序加工而成。与传统的地板相比，石塑地板具有绿色环保、超轻超薄、超强耐磨、超强防滑、高弹性和超强抗冲击性等优点。然而，现在的石塑地板大多功能单一，缺乏功能性。
茶叶中含有茶生物活性成分，主要包括生物碱以及茶生物活性成分，茶生物活性成分中含有黄烷醇类、花色苷类、黄酮类、黄酮醇类和酚酸类等，茶生物活性成分具有很强的抗氧化性以及抗菌防腐性能。因此，利用茶生物活性成分与石塑材料相结合制备一种具有抗菌性能的石塑地板具有一定的市场前景。
发明内容
有鉴于此，本发明提供了一种含茶生物活性成分的大生物石塑地板，在石塑地板中添加茶生物活性成分，能够增加石塑地板的抗菌性能，且制备的石塑地板无异味，绿色环保。
本发明提供的含茶生物活性成分的大生物石塑地板，包括树脂基材及表面耐磨层；所述树脂基材包括以下重量份的原料：PVC树脂200～300份、白云石400～600份、茶生物活性成分50～100份、稳定剂10～20份、分散剂15～20份、润滑剂10～15份；
所述茶生物活性成分为茶多酚。
优选的，所述表面耐磨层包括以下重量份的原料：热塑性丁苯橡胶100～150份、PVC树脂100～150份和茶生物活性成分50～70份；
所述茶生物活性成分为茶多酚。
优选的，所述树脂基材的厚度为10～20mm，所述表面耐磨层的厚度为0.1～2mm。
优选的，所述稳定剂为钙锌稳定剂。
优选的，所述分散剂为烷基酚聚氧乙烯醚。
优选的，所述润滑剂为聚乙烯蜡或氯化石蜡。
本发明的另一目的是提供一种含茶生物活性成分的大生物石塑地板的制备方法，包括以下步骤：
(1)将白云石粉碎至400～500目后与PVC树脂按比例加入混料机中，在温度为140℃～150℃下进行加热搅拌20～30min；
(2)再将茶生物活性成分、稳定剂、分散剂和润滑剂按比例加入步骤(1)的混料机中，继续混合10～15min，得到均匀的混合物料；
(3)将步骤(2)的混合物料冷却至50～60℃；
(4)将冷却后的混合物料加入挤出机中，于温度为165～180℃下挤出成型，得到树脂基材；
(5)按比例称取热塑性丁苯橡胶、PVC树脂和茶生物活性成分，并在温度为140℃～150℃下加热搅拌混合30～50min，冷却至50～60℃后，在温度为165～180℃下挤出成型得到表面耐磨层；
(6)将树脂基材与表面耐磨层进行热压处理，然后进行分板、养生、开槽处理。
优选的，步骤(6)所述热压的温度为120～140℃，压力为15～20MPa。
优选的，步骤(6)所述养生过程是将石塑地板置于温度15～25℃，湿度为50～60％的室内静置30～50小时。
与现有技术相比，本发明具有以下优点：本发明制备的大生物石塑地板，制备方法工艺简单，能够在线连续生产。本发明的石塑地板的树脂基材采用PVC树脂、白云石和茶多酚为主要原料，加入少量的稳定剂、分散剂和润滑剂，由此得到的石塑地板不仅具有良好的力学强度、弯曲弹性、尺寸稳定性好等特点，在树脂基材及表面耐磨层中分别添加茶多酚，茶多酚作为天然的添加剂，无污染、绿色环保，使石塑地板具有良好的抗菌、抗氧化性能。本发明的石塑地板在树脂基材的表面增加了一层耐磨层，进一步增强了石塑地板的耐磨性能。
