摘要
以水溶性酚醛树脂、水玻璃和抑水剂为材料,基于溶胶-凝胶技术合成出一种互穿网络结构的有机-无机凝胶体系。互穿网络凝胶体系的交联时间随水溶性酚醛树脂浓度增大而缩短,交联强度则增强。当体系中水玻璃质量分数为0~3%时,交联时间随浓度增大而延长,交联强度随浓度增大而增强。水溶性酚醛树脂-水玻璃互穿网络结构致密且匀称,满足深部封堵的要求,可作为耐温堵剂使用。
In this paper,an interpenetrating network（IPN）organic-inorganic gel system was prepared by water soluble phenol-formaldehyde resin,sodium silicate and water-resistant agent based on sol-gel technology.The gelation time of IPN gel system shortens with the concentration increase of water soluble phenol-formaldehyde resin,while gelation strength increase.When the concentration of sodium silicate is 0~3%,the gelation time lengthens and the gelation strength enhances with concentration increase.The interpenetrating network structure formed by water soluble phenolic-resin and sodium silicate is dense and symmetrical.The system can be used as a high temperature plugging agent and satisfied the deep sealing condition.
