摘　　要：环氧改性漆酚的涂料因具备成膜快、耐酸碱腐蚀良好、耐磨性高等特点,而被广泛应用于工业防腐、仿古建筑、家具涂装等领域。本文以生漆中的漆酚为基料,经环氧改性处理后,进一步研制出4种改性涂料:清漆I、防腐涂料I、底漆I、红色涂料I,并进行性能测试。结果表明:漆酚与环氧树脂E44投料比为1∶1,溶剂HB用量为40%-45%,反应温度在127℃~130℃反应6h制备的环氧漆酚性能最优;当环氧改性漆酚的粘度控制在60pa·s,固含量在36%~45%,增加2%湿润剂及1.8%增稠剂后制调制出的4种涂料稳定性好,性能指标优于国家标准。Epoxy modified urushiol coatings have been widely used in industrial anticorrosion,antique building,furniture coating and other fields because of its fast filmforming,good acid and alkali corrosion resistance and high abrasion resistance.In this article,four kinds of modified coatings have been developed with urushiol in lacquer as base material in lacquer modified by epoxy:Varnish I,anticorrosive coating I,primer I,red coating I,and performance testing.The results showed that the epoxy urushiol had the best performance when the ratio of urushiol to epoxy resin E44 was1∶1,the amount of solvent HB was 40%~45%,and the reaction temperature was 127℃~130℃for 6h.When the viscosity of epoxy-modified urushiol is controlled at 60pa·s,the solid content is 36%~45%,and 2%wetting agent and 1.8%thickener are added,the four coatings prepared have good stability and the performance index is better than the national standard.
