Description

一种玻纤增强PVC塑胶托板及其制备方法
技术领域
本发明属于复合材料领域，具体涉及一种玻纤增强PVC塑胶托板及其制备方法。
背景技术
免烧砖塑胶托板是一种专门用于免烧砖生产过程中托起砖胚的辅助板材，因其长期承托大重量的砖块，所以对其强度有着很高的要求，否则容易断裂；同时由于长期经受水泥浆和日晒雨淋的使用环境，又要求其有较高的耐腐耐磨性和超长的使用寿命，目前市面上的免烧砖托板在承重强度和使用寿命上存在不足。
发明内容
为解决上述问题，本发明目的在于提供一种玻纤增强PVC塑胶托板及其制备方法。
为实现上述目的，本发明所采用的技术方案是：
一种玻纤增强PVC塑胶托板，其原材料成分及重量份数为：PVC树脂粉42～48份、废旧塑料粉12～18份、纳米碳酸钙18～22份、玻璃纤维8～12份、增韧剂2～3份、硅烷偶联剂3～4份、抗氧剂1～3份、润滑剂2～4份。
作为优选，所述的玻纤增强PVC塑胶托板原材料成分及重量份数为：PVC树脂粉45份、废旧塑料粉15份、纳米碳酸钙20份、玻璃纤维10份、增韧剂2份、硅烷偶联剂3份、抗氧剂2份、润滑剂3份。
所述的增韧剂为增韧剂ACR、SBC、MBS中的一种。
所述的抗氧剂为抗氧剂DNP或抗氧剂CA。
所述的润滑剂为石腊。
一种玻纤增强PVC塑胶托板的制备方法，包括以下步骤：1)按重量份数取PVC树脂粉、废旧塑料粉和纳米碳酸钙入混炼机中在100℃条件下混炼10min；2)再加入增韧剂、硅烷偶联剂、抗氧剂和润滑剂在100℃条件下继续混炼5min；3)将混炼后的混合料通过双螺杆挤出机挤出，挤出时采用侧向喂料方式向双螺杆挤出机内添加玻璃纤维，共同挤出成型。4)待成型后的板材冷却后裁切即得成品。
有益效果：
本发明的玻纤增强PVC塑胶托板以PVC和废旧塑料粉为主要原料，通过纳米碳酸钙作为补强剂，同时采用玻璃纤维增强，其机械性能大大提高，具有高强度、高硬度、高耐磨耐腐的特点，使用寿命长、成本低。
具体实施方式
下面对本发明做进一步的描述：
实施例1：
本发明的玻纤增强PVC塑胶托板原材料成分及重量份数为：PVC树脂粉45份、废旧塑料粉15份、纳米碳酸钙20份、玻璃纤维10份、增韧剂ACR 2份、硅烷偶联剂3份、抗氧剂DNP 2份、润滑剂石蜡3份。
