Abstract:An acrylate environmental adhesive was prepared by solution polymerization which used ethanol as solvent and N,N'-Methylenebisacrylamide(MBA) as crosslinking monomer,octadecyl acrylate as long-chain hydrophobic monomer,the NMR, IR, GPC, SEM, TGA and contact angle of the polymer were tested.Effects of reaction time,reaction temperature,crosslinking monomer and hydrophobic monomer on polymer,the optimal ratio of hard to soft monomer and the physical properties of the polymer film were studied.When reaction time was 4h,reaction temperature was 80 ℃,crosslinking monomer was 1 % (basd on the total mass of monomers,the same below),hard to soft monomer was 2:1~3:1,the molecular average weight of polymer was 12.86×104,thermal decomposition temperature was 309.3 ℃,glass transition temperature was 85.2 ℃ film,hardness reached to 4 H.With the addition of hydrophobic monomer,tensile strength and hydrophobicity of polymer film enhanced,when hydrophobic monomer was 3 %,tensile strength was 0.789 Mpa which improved 36.37 %,contact angle was 78.6 °,which improved 219.5 %.The prepared adhesive could be used for the solidification of sand soils and the fixation of sand panting,sand bottle drawing and relief painting for the effumability,fast permeability and no-pollution of ethanol.
