Abstract
Development of a protective polymer coating with high hydrophobic and adhesive properties
Incoming article date: 09.05.2020The results of the development of a polymer protective coating based on oligopiperylene styrene binder for the protection of concrete and metal surfaces of structures of buildings and structures from the effects of adverse natural and technogenic factors are presented. Modification of this binder with tetraethoxysilane in an amount of 3-20 wt. including allows you to get a protective coating with good hydrophobic properties. Introduction to the composition of 1-12 wt. including tetraisopropyl titanate significantly improves the adhesive and strength properties of the protective coating, which is associated with the formation of bonds between oligopiperylene styrene and tetraisopropyl titanate, due to chemical interaction between the reactive groups of these compounds. The developed protective polymer coating provides good adhesion to the working surface, is easy to apply technologically, the curing of the coating occurs at room temperature, and the improvement of the strength and hydrophobic characteristics of the coating will significantly expand its field of application.
