Studying the effect of Nano filler on epoxy properties used in storage tank low carbon steel protection

الملخص EN

In this study a nano epoxy coating had been prepared to be used for the protectionof the internal and external surfaces of storage tank (low carbon steel) from corrosion.

Apolymeric coating was reinforced with fillers such as red iron oxide, Zinc phosphate andnano titanium dioxide (TiO2) which have been used as anticorrosion.

Pieces from lowcarbon steel was picked from storage tank and coated with two layers, the first layer wasprepared from organic polymer (epoxy) with red iron oxide, the second layer wasprepared from epoxy with (a nano titanium dioxide and Zinc phosphate).

The fillers weight percentages were (0, 7, 10 and 13 % wt).

The nano epoxy coatinggave good results in limiting the corrosion, the corrosion rate results show that the bestpercentage of additives was (13, 10 % wt) in salt solution 1.0 % wt ( NaCl, Na2SO3 andKCl ).

The coating samples were immersed for 3 month at 25 OC in gas oil and cuttingoil then was characterized using spectroscopic method (FTIR), physical and chemicaltests add to characterization of particles size was done by SEM.

The samples of TiO2were characterized by XRD and evaluation of corrosion was made by using staticpotential test.
