Effect of sodium silicate addition on flame retardancy of the oil paint produced by modern paint company

Abstract EN

In order to produce a coating with suitable properties, many additives are included in a coating formulation to achieve specific property modifications. In this work , two kinds of flame retardant materials were used as additives to increase the combustion resistance , and to decrease the flame spread of oil paint, these are : soluble Sodium Silicate and Sodium Silicate powder with oil paint.

Different weight percent ratios (2.5 , 5 , 7.5 , 8.5 , 10 , 12.5 ,15 ) % for the two additives were added to oil paint to obtain different samples.

It was found that, good flame retardant, and distinct decreasing in flame spread (flame speed), of oil paint was obtained , in all weight percent ratios for all the samples of the two additives .

Self extinguishing was observed at the ratios (7.5, 8.5, 10, 12.5 ) % for the two additives , and ( no burning ) for them , were observed at (15) %.

The mechanical properties tests (adhesion force, impact strength) were carried out to painted samples with oil paint mixed with second additive for all the above ratios, after about month from its preparation , the samples complied with Iraqi standard specifications No.
