Novel waterborne acrylic resin modified by cellulose acetate butyrate was successfully synthesized by a homogeneous solution polymerization with 2-butoxy ethanol, cellulose acetate butyrate and acrylic monomers as raw materials, N, N - dimethyl ethanolamine as neutralization and γ-aminopropyltriethoxysilane (KH-550) as curing agent. The influences of the cellulose acetate butyrate and curing agent content on the properties of the waterborne acrylic resin were investigated. As a curing agent, KH-550 not only improved the cross-linking density of the resin effectively, but also bonded to the substrate to form a molecular layer of silane. Cellulose acetate butyrate and KH-550 were found to reduce the curing temperature of the resin. The tensile strength of the coating added with the curing agent (5.89 MPa) was significantly improved compared to that of cellulose acetate butyrate modified resin (1.49 MPa). This kind of environment-friendly waterborne acrylic resin has a strong potential application in wood coatings, automobile coatings and other fields.

以2-丁氧基乙醇，乙酸丁酸纤维素和丙烯酸类单体为原料，以N，N-二甲基乙醇胺为中和剂，γ-氨基丙基三乙氧基硅烷（KH-550），通过均相溶液聚合成功合成了乙酸丁酸纤维素改性的新型水性丙烯酸树脂。作为固化剂。研究了乙酸丁酸纤维素和固化剂含量对水性丙烯酸树脂性能的影响。作为固化剂，KH-550不仅有效地改善了树脂的交联密度，而且还与基材结合形成了硅烷分子层。发现乙酸丁酸纤维素和KH-550降低了树脂的固化温度。添加了固化剂的涂层的拉伸强度（5。与醋酸丁酸纤维素改性树脂（1.49 MPa）相比，显着提高了89 MPa）。这种环保型水性丙烯酸树脂在木器涂料，汽车涂料等领域具有广阔的应用前景。
