摘　　要：以砂浆块为基材,考察了表面活性剂对渗透型环氧树脂防水涂料渗透性能和力学性能的影响。结果表明,通过添加表面活性剂,能有效降低涂料的接触角,从而改善其润湿性能,进而提高其渗透性能。添加了表面活性剂的渗透型环氧树脂防水涂料对砂浆块的渗透深度最大达到10 mm以上,砂浆的抗压强度最大提高了278%。添加表面活性剂能提高渗透型环氧树脂防水涂料的防水和补强作用。Influences of surfactants on permeability and mechanical properties of permeable epoxy waterproofing coatings are investigated taking mortar as the substrate. The results show that the contact angle of the coating can be effectively reduced by adding the surfactant, so the wettability and the permeability of the coating are improved. By adding surfactants, the penetration depth of the coating on the mortar block is up to 10 mm, and the compressive strength is increased by 278%. The addition of surfactants improves the waterproofing and reinforcing effect of permeable epoxy waterproofing coating.
