用于驱油聚合物的改性纳米二氧化硅功能单体
摘要：
本发明涉及一种用于驱油聚合物的改性纳米二氧化硅功能单体，所述单体由以下方法制备得到：(1)利用纳米SiO2和氨基硅烷偶联剂反应得到氨基改性的纳米SiO2，并通过控制氨基硅烷偶联剂的添加量来控制纳米SiO2表面氨基的含量；(2)利用过量的含碳碳双键的改性剂与氨基改性的纳米SiO2反应得到具有反应活性的碳碳双键改性纳米SiO2单体。本发明所述的用于驱油聚合物的改性纳米二氧化硅功能单体，不仅可以根据需要在纳米SiO2表面可以定量的接枝上具有反应活性的碳碳双键，而且可以方便地通过控制含有氨基的硅烷偶联剂的量来控制接枝上的碳碳双键的含量。
摘要（英）：

The invention relates to a modified nanometer silica functional monomer for an oil-displacement polymer. A preparation method of the modified nanometer silica functional monomer comprises the following steps that 1, nanometer SiO2 and an aminosilane coupling agent undergo a reaction to produce amino-modified nanometer SiO2, and the content of amino groups on the surface of the nanometer SiO2 is controlled by control of a use amount of the aminosilane coupling agent, and 2, an excess amount of a modifier containing carbon-carbon double bonds and the amino-modified nanometer SiO2 undergo a reaction to produce a carbon-carbon double bond-modified nanometer SiO2 monomer with reaction activity. The modified nanometer silica functional monomer for an oil-displacement polymer can quantificationally graft carbon-carbon double bonds with reaction activity to the surface of the nanometer SiO2 according to demands and is convenient for control of the content of the grafted carbon-carbon double bonds by control of a use amount of the aminosilane coupling agent.
