摘要
应用溶解度参数理论 ,通过对环氧树脂、聚酰胺树脂、酚醛树脂 3种树脂均相溶液的适当掺混 ,并对各种清漆配方性能测试比较 ,选择出附着力好、抗冲击强度好、耐酸耐碱等化学腐蚀性强等综合性能优良的溶剂型环氧 -酚醛 -聚酰胺树脂清漆。其适宜配方(wB)为 :E -4 4环氧树脂 3 0 52 % ,低分子聚酰胺树脂 1 0 2 6% ,酚醛树脂 1 0 2 7% ,邻苯二甲酸二丁酯 3 51 % ,二甲苯 /环己酮 (质量比 1 /1 ) 8 94 % ,二甲苯 /正丁醇 (质量比 4 /1 )2 0 85% ,二甲苯 /环己酮 (质量比 3 /1 ) 1 5 3 9%。
In this work, with the solubility parameter theory, solvent-based varnish with excellent properties was prepared by mixing epoxy, polyamide and bakelite resins with a proper composition. The most suitable formula for varnish is as follows in weight percent: E-44 epoxy resin 30 52%, bakelite resin 10 27%, low-molecular weight polyamide 10 26%, dibutyl (o-)phthalate 3 51%, xylene/cyclohexanone(mass ratio 1/1)8 94%, xylene/n-butanol(mass ratio 4/1)20 85% and xylene/cyclohexanone(mass ratio 3/1)15 39%.
