Description

一种红外光谱FTIR检测透明剂NX8000含量的方法
技术领域
本发明属于分析检测领域，具体涉及一种红外光谱FTIR检测透明剂NX8000含量的方法。
背景技术
超高熔融指数聚丙烯树脂的透明料产品，使用透明剂MilladNX8000解决了第三代透明剂的制品透明性偏低、颜色发黄、析出物过高无法通过医用等级认证等问题，第四代透明剂在使用过程中产品的雾度不会随着熔融指数的升高而变大，尤其适用于高指数的透明料，第四代透明剂还因透明料的加工温度降低带给下游用户能耗的降低和成本的下降。
发明内容
本发明的目的在于建立了红外光谱FTIR测试透明剂NX8000含量的方法，由此可测出MilladNX8000物质的含量。进行超高熔融指数透明料的生产。具体技术方案如下：
一种红外光谱FTIR检测透明剂NX8000含量的方法，包括如下步骤：
1、样品制作
把聚酯片置于铝板上，取少许样板放在其上，然后以聚酯片和铝板覆盖，把此组件放在预先调整到180℃的加热机的加热板上，持续1分钟后，在压力为4MPa条件下保压约30s，降压后，把组件从加热机中取出，冷却至室温，移取聚酯片即可取到所需薄膜；在制得的薄膜中寻找一处两面光滑且厚度均匀约为1mm左右(以测微计测得)的区域，在此区域切割2cm×4cm长方形片备用。
2、制作标准曲线
根据制得的不同含量及浓度的标准样品500-5000mg/Kg七个，制备标准曲线数据，储存好备用；。
3、扫描样品：将样品放入样品室，对样品进行扫描。
进行标准浓度分析：可从“组成”中看到待测样品参照标准曲线文件计算的浓度。直接报出结果即可。
本发明的有益效果
本方法是把试样按要求制成1mm左右的样板，然后测其红外光谱强度，再与事先作好的标准曲线对照查得试样含量。本发明的方法可以与雾度测试结果相互印证，为品质控制提供更好参考。
具体实施方式
下面结合具体实施例对本发明作进一步说明。
实施例1
由于物质自身官能团和总体构型(如双键、叁键)的差异，对红外光谱强度产生增强或减弱的效应，此过程与试样含量成正比，由此可测出MilladNX8000物质的含量。
用红外光谱测试NX8000K的原理是利用它的特征吸收峰的面积来计算的。我们制备了标准NX8000K含量的雾度板片，含量从500ppm～5000ppm，在红外光谱上分别进行扫描，并计算628-1吸收峰的面积，分析发现这个峰的面积与NX8000K的含量几乎成正比，可以拟合成一条标准曲线。然后在设备上建立了一个NX8000K含量的计算方法。
当对一个未知NX8000K含量的板片测试时，先扫描仪器背景，然后放上板片(扫描中心位置)，扫描样品。然后选取设定好的NX8000K定量计算方法，即可自动计算出NX8000K的含量。
本方法是把试样按要求制成1mm左右的样板，然后测其红外光谱强度，再与事先作好的标准曲线对照查得试样含量。
