Investigation of adhesive-strength characteristics of fire-retardant epoxy polymers modified with metal-containing additives

Abstract

Abstract Composite materials based on epoxy oligomers due to their unique properties are widely used in various fields of construction and mechanical engineering, including fire retardant coatings. The introduction of flame retardants and dispersed inert fillers as a rule, affects the structure of epoxy polymers. When addressing issues related to the creation of flame-retardant, composite materials, there is insufficient data on the impact of dispersed mineral fillers on their performance properties. Attention is mainly paid to the indicators of flammability, toxicity of combustion products and thermophysical properties of the coating. Therefore, the aim of this work is to conduct experimental studies of changes in the adhesive and strength characteristics of fire-retardant epoxy polymer from the content of metal-containing additives. As a result of experimental studies, it was found of that changing the component composition of the composition can vary widely the adhesive strength characteristics of fire-retardant epoxy polymers. The obtained data must be taken into account when developing epoxyamine coatings for fire protection of building structures and technological communications.
