聚对苯二甲酸乙二醇酯/蒙脱土纳米复合材料的制备方法
摘要：
一种聚对苯二甲酸乙二醇酯/蒙脱土纳米复合材料的制备方法，包括如下步骤：(1)向反应器中加入对苯二甲酸、乙二醇，反应器加热升温并进行搅拌，进行酯化反应，生成酯化产物；(2)酯化产物进行打碎，研磨至细小粉末状，得到酯化产物粉体；(3)将酯化产物粉体和负载催化剂的改性蒙脱土的混合物进行低真空缩聚反应；(4)低真空缩聚反应过后进行高真空缩聚反应，得到聚对苯二甲酸乙二醇酯/蒙脱土纳米复合材料。
摘要（英）：

A preparation method of a polyethylene glycol terephthalate/montmorillonite nano composite material comprises the following steps: 1) adding terephthalic acid and ethylene glycol into a reactor, heating the reactor to increase the temperature with stirring to perform an esterification reaction to obtain an esterification product; 2) crushing and grinding the esterification product into fine powder to obtain an esterification product powder; 3) performing low-vacuum condensation polymerization to a mixture of the esterification product powder and modified montmorillonite supporting a catalyst; and 4) performing high-vacuum condensation polymerization to obtain the polyethylene glycol terephthalate/montmorillonite nano composite material.
