首先用亚麻酸与丙烯酸将双酚A型环氧树脂的环氧基开环酯化,制备出单脂肪酸环氧酯丙烯酸酯(中间体),再将中间体与丙烯酸(酯)单体接枝共聚,由此制备水性环氧酯-丙烯酸酯树脂杂化体;讨论了开环催化剂、终点酸值、中间体/丙烯酸酯单体质量比、亲水单体AA用量等对水性杂化体的合成和性能的影响. 结果显示:第一步开环催化剂选择四丁基溴化铵,第二步为氧化锌;开环反应最终酸值控制在9~14 mg(KOH)/g;中间体/丙烯酸酯单体最佳质量比为0.8∶1~1.1∶1;亲水单体最佳用量为5.2%~6.9%. 通过对树脂的性能测试,结果表明树脂固含可达40%,具有挥发性有机物低、黏度低、耐水性、防腐性能好等优点. 该树脂可用于配制低温烘烤型底面合一防腐涂料用于金属防护.
- Abstract:

The linolenic acid epoxy-ester acrylate(an intermediate product)was produced by ring-opening esterification of bisphenol A epoxy with linolenic acid and acrylic acid(AA).By using its grafting copolymerization with acrylate monomers, the water-borne hybrid of epoxy ester-acrylate resin was synthesized. The effect of ring opening catalyst, hydrophilic monomer AA, final acid value, and the intermediate product/acrylate monomers on synthesis and performance of the water-borne hybrid was discussed. The results show that Tetrabutyl ammonium bromide and Zinc oxide are chosen for two step ring opening catalyst; the final acid values are 9-14 mg(KOH)/g, the optimal values of the intermediate product/acrylate monomer are 0.8∶1-1.1∶1, and the optimal dosage of AA is 5.2-6.9%. Through the detection of the water-based hybrid properties, it can be discovered that the solids content of resin reaches 40%, which has lower volatile organic compounds and viscosity, better water resistance and corrosion resistance.
