The Development of Polymer Fire-Resistant Thermal Insulation Coating Filled with Anthropogenic Waste

Abstract

The research presents the development results of the polymer coating possessing good insulation and fire-resistant properties, containing electroplating production waste from the machine-building enterprise. This coating is designed for thermal insulation and fire protection of concrete and metal surfaces of various construction structures and industrial equipment. The coating is developed basing on siloxane rubber, catalyst K-18, hollow carbon microspheres and anthropogenic waste-electroplating sludge, used as flame retardant additive. The hollow carbon microspheres provide the increase in coating strength and thermal insulation properties. The electroplating sludge in the amount of 5–15 wt.p. facilitates self-extinguishing effect of thermal insulation coating, reducing the burning time without deterioration of the operational properties – strength, adhesion, while solving another important task-safe disposal of electroplated sludge. The studies have shown that this composition allows producing relatively inexpensive, but quite effective polymer coating characterized by good thermal insulation, fire-resistance and physico-mechanical properties.
