Polystyrene Paint for Protecting Concrete Structures from Corrosion

Abstract

The purpose of this work is development and study the properties of varnish paint materials based on a foam polystyrene solution, intended for corrosion protection of concrete and reinforced concrete building structures. This goal determined the formulation of the following tasks:
•     Select solvents and determine the optimum polymer concentration
•     To develop optimal compositions of varnish paint materials
•     Determine the durability of the developed varnish paint materials under various operating conditions.

Information about the possibility of using foam polystyrene waste in the development of paint formulations is given. The optimal types of solvents have been determined. The optimum concentration of the polymer in the solvent has been selected. The long-term strength of polymer coatings has been investigated. The fragile mechanism of destruction for films based on expanded polystyrene solution has been established. It was revealed that in the process of thermal aging of plasticized polymer films based on expanded polystyrene solutions, the nature of the destruction of the coating changes from forced elastic to brittle. The change in the value of the structure-sensitive factor was revealed depending on the content of the plasticizer. In the course of aging, a change in the ratio between the short-term and long-term strength of plasticized coatings is observed.
