Description

一种合成聚酯/聚碳酸酯树脂合金的方法
技术领域：
本发明属于聚合物改性中的聚合物合金制备技术，特别是涉及一种聚酯/聚碳酸酯树脂合金的制备方法。
背景技术：
目前聚酯类工程塑料是工程塑料领域中的一个重要发展方向，现在市场上用于工程塑料的聚酯品种主要有PBT、PC和PET三大类，其中聚碳酸酯树脂(PC)的综合性能优异，尤其具有突出的抗冲击性、透明性和尺寸稳定性，优良的机械强度和电绝缘性，使它在电子、电气、汽车、建筑等领域得到广泛的应用。但是PC对缺口的敏感性较大，加工时容易发生应力开裂，并且加工温度较高，使得加工困难，并且价格偏高。为克服PC的性能缺陷并降低价格，许多以PC为主要原料的共混合金正在大力开发。
由于PET聚酯纤维应用等技术与市场趋于饱和，世界各国面对日益增长的PET聚酯产量，纷纷开发PET的非纤维用已成为发展的必然趋势，PET用于工程塑料的一个最大的缺点是耐冲击性差，这是由于PET聚酯大分子链的刚性引起的，因此提高PET工程塑料的抗冲击性能是拓展其产品应用领域的关键问题之一。聚酯和聚碳合金不仅增强了PET聚酯的韧性，也改进了耐化学性能，具有很高的耐冲击性能。
发明内容：
本发明的目的是提供一种聚酯(PET)/聚碳酸酯树脂(PC)合金的制备方法。通过加入第三组分作为聚合物合金材料的增韧剂，改善聚酯和聚碳合金二元共混物的力学性能，从而扩展PET聚酯在工业中的应用领域，提高产品的附加值，同时为制备高性能PET聚酯工程塑料提供新的途径。
本发明是通过以下技术方案来实现的：
通过选用普通聚酯切片/聚碳酸酯树脂为原料，选用合适的塑料加工助剂，采用双螺杆熔融共混的工艺路线，制备聚酯和聚碳合金聚合物合金材料。
首先对聚酯切片(PET)、聚碳酸酯树脂(PC)两种原料进行干燥处理，以除去切片中的水分，从而保证熔融挤出过程的正常进行。聚碳酸酯树脂在110～115℃下干燥10小时，PET聚酯切片在120～125℃下干燥10小时；按重量百分比称取干燥后的聚酯(PET)切片60％和聚碳酸酯树脂(PC)40％，加入原料总重量的0.2～0.3％抗氧剂1010，将上述原材料在高速混合机中混合均匀；双螺杆挤出机各段温度：机身温度220℃，235℃，255℃，265℃，265℃；机头温度265℃；经熔融共混，熔体挤出后经水冷，然后经过切粒机切粒，粒料干燥后在注塑机上制成标准试样，试样注塑后，平衡24小时进行力学性能测试。
采用南京科亚塑料机械有限公司的TE-35双螺杆挤出机，通过熔融共混工艺路线，制备聚酯和聚碳酸酯树脂合金材料；
采用深圳市新三思材料检测有限公司生产的CMT6104电子万能实验机测试聚酯和聚碳酸酯树脂合金材料的力学性能。
发明效果：
本发明聚酯和聚碳酸酯树脂合金的制备方法属于聚合物改性技术。其特征在于：选择聚碳和PET聚酯切片为基本原料，EVA为增韧剂，1010为抗氧剂，通过双螺杆熔融共混的工艺路线，得到聚酯和聚碳酸酯树脂合金材料。
本发明的目的是通过高分子共混改性的方法，扩展PET聚酯在工业中的应用领域，提高产品的附加值，同时为制备高性能PET工程塑料提供新的途径。用本发明得到的聚酯/聚碳酸酯树脂合金切片可用于加工各种仪器、仪表及汽车配件等。开展聚酯/聚碳酸酯树脂合金合金的研究一方面拓宽了PET的应用领域，另一方面又增加了PET的附加值。目前PC的售价约为3.5万元/吨，PET的价格大约在1.2万元/吨左右，成功开发聚酯/聚碳酸酯树脂合金，并能在PC的应用领域部分取代PC，必将大大拓宽PET的应用领域，也将带来可观的经济效益。
