Effect of Sulfuric Acid /Sodium Hydroxide /Sodium Chloride on Properties of Polyurea
This paper mainly studies the glossnesschange、mechanical properties change and hardness change of polyurea coatings during the immersing experiment. The result of the glossness experiment shows that Qtech-116 polyurea sample glossness declining rate were 18.33%, 3.69% and 0.83% after immersed in 5％H2SO4、5％NaOH and 3.5％NaCl for 60d.The mechanical properties results shows that the tensile strengt decrease rate were 16.30%、2.69% and 2.28% after immersed in 5％H2SO4、5％NaOH and 3.5％NaCl for 60d. Qtech-116 polyurea sample hardness showns declined 0.83%、no change and increased 35.81% respectively after immersed in 5％H2SO4、5％NaOH and 3.5％NaCl for 60d.
