Abstract:

Unsaturated polyester resin artificial marble with the fillers of Ca(OH)2 and Al(OH)3 were soaked by 10% NaOH, 20% H2SO4 and toluene by 15, 30, 60 days.The flexural strength was mensurated and the mechanical properties was analyzed. The results showed that flexural strength was reduced rapidly with prolonging of the soaking time in corrosion solutions. The artificial marble soaked into corrosion solutions was observed by microscope. The observations showed that corrosion was dead against the polymer of unsaturated polyester resin,and the cohesive force between the polymer and fillers was reduced. The results of corrosive tests showed that toluene as organic solvent had a corrosion strong effect on polymer of unsaturated polyester resin，sodium hydroxide was relative strong, and sulfuric acid was relative weak.
