为制备绿色环保,对大气环境和人员健康均友好的临时保护性可剥离涂料,采用D40和200#溶剂油组成的复合溶剂溶解主成膜树脂,辅以耐老化树脂,添加合适的补强填料和助剂,制备了一种不起泡、开裂、脱落的高性能临时保护性可剥离涂料。该涂料附着力良好,又较易完整去除,还对强酸、强碱的浸蚀作用具有较强的耐受性及长效耐候性。与传统的以苯类混合溶剂制备的临时保护性可剥离涂料对比可知,该涂料黏度更低,工艺性更好,综合性能相当,但对施工人员及环境更加友好。

In order to prepare a temporary protective peelable coating that is environmentally and friendly to the atmospheric environment and personnel health.In this paper,the compound solvent of D40 and 200#solvent oil is used to dissolve the main film-forming resin,supplemented by anti-aging resin,and adding suitable reinforcing fillers and additives to prepare a high-performance temporary protective peelable coating without foaming,cracking and falling off.This kind of coating not only has good adhesion,but also can be easily removed completely.It also has strong resistance to the corrosion of strong acids and alkalis and long-term weather resistance.Compared with the traditional temporary protective peelable coating prepared with benzene mixed solvent,it is known that this coating has lower viscosity,better manufacturability and equivalent comprehensive performance,but is more friendly to construction personnel and the environment.
