摘要

A CaO-SiO sub 2 -H sub 2 O macromolecular-ionomer complex was found to be formed in the superficial layers of MMA-TMPTMA copolymer composite films made with filler containing hydraulic cement during exposure in an autoclave at temperatures up to 200 exp 0 C. This superficially formed complex in terms of self-healing protective layers, acted to prevent the hydrothermal deterioration of the original composite films, which is important if the films are used as protective layers on metals. Studies of the adhesion of the complex composite coatings to chemically treated metal surfaces were also performed. It was found that the surface topography of hopeite crystalline layers results in an increase in wetting forces and mechanical interlocking forces. (ERA citation 09:050172)
