Description
技术领域
本发明属于高分子材料技术领域，尤其涉及一种透明生物基片材及其制备方法。
背景技术
目前市面上的片材类透明包装材料主要有PP(聚丙烯)、PS(聚苯乙烯)、PET(聚对苯二甲酸乙二醇酯)、PVC(聚氯乙烯)、PA(聚酰胺)等，这些材料大部分都来自石化产业或者高耗能产业。包装材料在生产过程中会产生或需要添加一些有毒有害物质，对人体和环境造成危害，而且废弃的包装材料在自然环境中难以分解，会造成白色污染，因此寻找一种低碳环保的材料来替代这些包装材料成了当务之急。在生物基塑料中，淀粉这种天然高分子物质具有来源广泛、价格低廉、再生周期短等优点，当使用不同的淀粉、改性剂以及其他辅料，并且采用不同配比时，材料的透明度和机械性能也不同。目前的生物基塑料透明度和撕裂强度不够，影响其使用范围。
发明内容
鉴于上述问题，本发明的目的在于提供一种透明生物基片材及其制备方法，旨在解决现有生物基塑料透明度和撕裂强度不够的技术问题。
为了达到上述目的，一方面，本发明提供了一种透明生物基片材，其包含的原料以及各原料组分质量配比如下：
进一步的，所述淀粉为玉米淀粉、甘薯淀粉、小麦淀粉、绉皮豌豆淀粉中的一种或以上。
进一步的，所述增塑改性剂为聚乙烯醇、马来酸二丁酯、甘油三乙酸脂、山梨醇、丙三醇、柠檬酸三丁酯、甲基丙烯酸、马来酸酐-丙烯酸共聚物、烷基磺酸苯酯中的一种或以上。
进一步的，所述偶联剂为硅烷偶联剂、铝酸酯偶联剂或钛酸酯偶联剂。
进一步的，所述聚丙烯为拉丝级聚丙烯。
进一步的，所述成核剂为山梨醇类透明成核剂、有机磷酸盐类成核剂或羟酸盐类成核剂。
进一步的，所述润滑剂为聚乙烯蜡、白油、氧化聚乙烯蜡、环氧硬脂酸辛酯中的一种或以上。
另一方面，本发明还提供了一种透明生物基片材制备方法，包括下述步骤：
1)、按照如权利要求1-7任一项所述的透明生物基片材的原料配比备料；
2)、将准备好的淀粉经粉碎机磨碎，细化至1000目以上；
3)、将细化好的淀粉加入到高速搅拌机中，再加入准备好的增塑改性剂进行改性，温度设置为60～140℃，搅拌10～40min；
4)、按照配比加入准备好的偶联剂、聚丙烯、茂金属聚乙烯、成核剂以及润滑剂，保持温度与改性时温度一致，搅拌5～20min，然后放出物料；
5)、将放出的物料加入到冷混锅内搅拌10～15min，待物料冷却到50℃以下；
6)、将冷却后的物料加入到双螺杆挤出机挤出造粒；
7)、将造粒后的物料加入锥形双螺杆片材机，经过三辊制成所述透明生物基片材。
进一步的，步骤6)中，所述双螺杆挤出机的长径比为44:1～52:1，机筒各区温度设置为120℃～200℃，机头温度设置为160℃～170℃，螺杆转速为240～280转/分。
进一步的，步骤7)中，所述锥形双螺杆片材机中的挤出机料筒温度设置为180℃～230℃，模头温度设置为170℃～190℃，模头出口大小根据所需片材的宽度和厚度设定。
本发明的有益效果是：本发明选材主料为淀粉，是可再生资源，可以减少对不可再生资源的依赖，而且片材在加工过程中不加入有毒害的物质，不产生有毒有害的气体，整个加工过程对人体和环境无害。本发明通过选取适合原料以及设计各原料的质量配比，制得的生物基片材具有很高的透明度和抗拉撕性能。
