Using the poly-acrylic acid ester modified porous silica as fillers, the E-44 epoxy resin as matrix, ethylene diamine as curing agent prepared the sound absorption coating, and the sound absorption properties of and wear resistance were tested. The results showed that: the coating wear resistance increased with the addition of filler increasing,and then decreased. The wear mass of 60%filler coating is the lowest. The absorption coefficient increases with the filler increasing, the average absorption coefficient can reach 0.22 of 1000Hz frequency sound.
