Study on Anti-Crack Mechanism in Geopolymer Based Inorganic Coating
2010
Building coating which prepared with geopolymer can easily develop crack when it is applied, this article analyzes the reasons of crack of our inorganic coating with inorganic material crack theory. And we bring forward to the better approaches that can solve the problem of coating crack:e.g. apply to smaller particle size, fitting thickness of coating, add organic polymer into the inorganic coating and become or- ganic-inorganic hybrid coating, increase rates of absorbing stress of coating by adding nano-ZnO, we improve the capability of the coating anti-crack through these means, and solved the crack problems of geopolymer inorganic coating.
