Description

一种环保PVC膜及其制备方法
技术领域
本发明属于PVC膜技术领域，具体地说，涉及一种环保PVC膜及其制备方法。
背景技术
聚氯乙烯，英文简称PVC(Polyvinyl chloride polymer＝PVC分子结构)，是由氯乙烯在引发剂作用下聚合而成的热塑性树脂，是氯乙烯的均聚物。氯乙烯均聚物和氯乙烯共聚物统称之为氯乙烯树脂。PVC为无定形结构的白色粉末，支化度较小。工业生产的PVC分子量一般在5万～12万范围内，具有较大的多分散性，分子量随聚合温度的降低而增加；无固定熔点，80～85℃开始软化，130℃变为粘弹态，160～180℃开始转变为粘流态；有较好的机械性能，抗张强度60MPa左右，冲击强度5～10kJ/m2。
PVC为微黄色半透明状，有光泽，透明度胜于聚乙烯、聚丙烯，差于聚苯乙烯，随助剂用量不同，分为软、硬聚氯乙烯，软制品柔而韧，手感粘，因此PVC膜被广泛应用于各个行业。
但是，现有的PVC膜使用寿命有限，尤其是低温和高温环境。
发明内容
本发明克服了现有技术中的缺点，提供了一种环保PVC膜及其制备方法，具有环保无污染的特点，而且稳定性好，经久耐用，寿命长。
为了解决上述技术问题，本发明是通过以下技术方案实现的：
一种环保PVC膜，按照质量比，包括：PVC 80-90，DOP 40-45，碳酸钙2-5，稳定剂2-3，大豆油5-10，TiO2 0.5-2，颜料0.2-0.4。
进一步，还包括所述PVC质量分数0.5-1％的石墨烯。
进一步，还加入所述PVC质量分数0.5～1％的蛋白质粉。
进一步，还加入所述PVC质量分数2～4％的尿素。
进一步，还加入所述PVC质量分数0.2～0.4％的羟丙基甲基纤维素。
进一步，还加入所述PVC质量分数1～2％的低秒硝化棉。
进一步，还加入所述PVC质量分数3～4％的儿茶酚。
一种环保PVC膜的制备方法，包括以下步骤：
1)对以上配比的物质进行配料，然后对其以1300-1400转/min的转速搅拌均匀；
2)经过密炼和精炼工序，其中，密炼温度140-150℃，密炼时间4-5min，精炼温度160-170℃，6-7min。
3)降温至150-160℃下挤出过滤经压延和温炼后冷却定型和切边。
与现有技术相比，本发明的有益效果是：
本发明所述一种环保PVC膜及其制备方法，按照质量比，包括：PVC80-90，DOP 40-45，碳酸钙2-5，稳定剂2-3，大豆油5-10，TiO2 0.5-2和颜料0.2-0.4，环保无污染，通过该配比制备的产品经久耐用，使用寿命长。
具体实施方式
以下对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
本发明所述一种环保PVC膜，按照质量比，包括：PVC 85份，DOP 42份，碳酸钙3份，稳定剂2.5份，大豆油6份，TiO2 1份和颜料0.3份，还包括PVC质量分数0.6％的石墨烯，0.7％的蛋白质粉，2.5％的尿素，0.3％的羟丙基甲基纤维素，1.5％的低秒硝化棉，3.5％的儿茶酚。
石墨烯具有超高的表面硬度，当在PVC膜中平均分布时，可以提供产品表面超高耐磨性。
蛋白质粉具有气吸湿传导性，可赋予其透气吸湿的功能。
尿素具有阻燃的作用，羟丙基甲基纤维素具有pH稳定性、保水性、尺寸稳定性、以及广泛的耐酶性、增稠性和粘结性等特点，低秒硝化棉使PVC膜的硬度与柔韧性取得了很好的平衡，儿茶酚提高PVC膜的稳定性。
一种环保PVC膜的制备方法，包括以下步骤：
1)对以上配比的物质进行配料，然后对其以1300-1400转/min的转速搅拌均匀；
2)经过密炼和精炼工序，其中，密炼温度140-150℃，密炼时间4-5min，精炼温度160-170℃，6-7min。
3)降温至150-160℃下挤出过滤经压延和温炼后冷却定型和切边。
对得到的环保PVC膜进行性能测试，其结果如下：
最后应说明的是：以上仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换，但是凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
