【摘要】 采用热塑性弹性体为基体材料制备不同配方的铝合金化学铣切保护涂料。实验包括涂料中酚醛树脂的合成,涂料的制备。所做涂料的性能考核包括外观、粘度、固体含量、抗张性、断裂伸长率、浸蚀比、致密性、剥离强度等。最后与美国同类产品性能对比。研究表明,自制的铝合金化学铣切保护涂料的涂膜透明均匀、剥离强度大小适中、耐强碱,满足化学铣切工艺要求,也基本上与美国同类产品性能相当。更多还原

【Abstract】 This study adopted thermoplastic elastmer as the base material of protect coating for chemical milling of aluminum alloy.The experiment included synthesis of PF resin;preparation of protective coating with different kinds of formula;analysis of the performances of protective coating: such as appearance,viscosity,solid content,tensility,rupture elongation ratio,etching ratio,compatibility,peel ability and so on.Finally,the performance of the protect coating is compared with that of the similar products of the USA.Experiment proves that characteristics of the self-produced protective coating,such as transparent uniform film,proper peel strength,perfect aldaline resistance,meets the requirements of chemical milling,approaches that of American products basically.更多还原
