doi:10.19491/j.issn.1001-9278.2021.02.002

Abstract

Abstract:

A permeable epoxy coating was prepared through a combination of bisphenol-A epoxy resin （E51）， furfural， acetone phenolic modified amine， 2，4，6-tris（dimethylaminomethyl）phenol （DMP-30） and other additives， and its reaction mechanism was analyzed. The influence of different additives on the film-forming ability of the coating was discussed. The depth of penetration to the surface of concretes with different strength grades along with other basic properties was also investigated. The results indicated that the BYK-333-modified coating exhibited an optimum film-forming ability and good permeability. The coating achieved bonding strength of 4.5 and 3.6 MPa on the dry base concrete surface and the wet base concrete surface， respectively. Moreover， the coating gained a maximum penetration depth of 5 mm on the C30 concrete surface， indicating good chemical resistance.
