| Although have many features such as no solvent, pollution-free and high-recovery and utilization ratio, the powder dope is mainly used in decorated field in our country. Recently, several corrosion resistant powder dope developed by domestic researcher, but the property and the quality can't satisfy the demands of corrosion and prevention field obviously. The powder dope used to the corrosion resistance especially heavy corrosion resistance and special circumstance need to develop immediately. This thesis researched the basal prescription of epoxy powder dope, then attained preferable corrosion resistance property as well as the preferable mechanical and reserved property through the modifying of the powder dope. The detailed work was as follow:1. We analysed ingredients' dosage the means of the positive intersection experiment and then found the basal prescription of powder dope. 2. The solidifying temperature couldn't be debased distinctly if added the solidifying agent only. In the DSC chart the preliminary temperature reduce from 160℃to 80℃. The solidifying accelerant can improve the solidifying speed obviously and the mechanical property keeps constantly.3. The bakelite are added to the epoxy system to improve the property, and the result shows the water resistance, the acid resistance are improved apparently. Furthermore, this paper also discuss the cured mechanism ordinarily.4. The lanthanide is added to the epoxy system to reparation the brittleness of the dope. The investigation of IR, DSC, GPC shows that the water resistance, the corrosion resistance, the stockpiling property and mechanical strength are improved apparently.
