　　以双酚 A酚醛环氧树脂( NEP)为基础树脂，以苯甲酸(BA)为开环剂，将NEP的部分环氧基团打开合成含羟基的双酚A酚醛环氧树脂(BNEP)。通过马来酸酐(MA)与 BNEP上的羟基反应,在BNEP上引入羧基亲水性基团和碳碳双键，制得自乳化的阴离子双酚A酚醛环氧树脂(WNEP)。然后将其通过相反转乳化技术制备成WNEP乳液并作为浸渍剂应用于机油滤纸上。采用傅里叶红外光谱仪(FT-IR)和多功能光电子能谱仪(XPS)对WNEP的化学结构与被浸渍滤纸表面的化学成分进行表征，证明成功合成了WNEP。通过粒度分析仪和透射扫描电子显微镜(TEM)对WNEP乳液的粒子分布和形貌进行分析。对不同开环率的WNEP树脂和被浸渍滤纸进行热失重分析(TGA)，并用表面接触角测试仪测定被浸渍滤纸表面的水接触角。结果表明：热稳定性会随着树脂开环率的增加而降低，浸渍后的滤纸表面与水的接触角可达130°，WNEP的最佳开环率为35%，将其应用于机油滤纸时可显著提高滤纸的耐热性和抗水性。

An anionic waterborne epoxy resin emulsion was synthesized based on bisphenol-A novolac epoxy resin (NEP). The modification agents used are benzoic acid (BA) and maleic anhydride (MA). The anion waterborne bisphenol-A novolac epoxy resin (WNEP) emulsion was prepared by phase inversion emulsification technique, and was applied to treat the oil filter paper as impregnating agent. The chemical structure and surface chemical composition of the WNEP were characterized respectively by infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The granularity analyzer and transmission electron microscope (TEM) were used to examine the emulsion particle dispersion and microscopic properties of WNEP emulsion. The thermal degradation of WNEP with different ring-opening ratios and filter papers impregnated by them were studied by thermogravimetric analysis (TGA). The contact angle of impregnated filter paper surface and water was measured by static contact angle test. It was observed that the WNEP with 35%ring-opening ratio shows good results, and it could significantly improve the thermal stability and water resistance of the impregnated oil filter paper.
