flame retardants

Today, an urgent problem in modern construction is the development of highly functional fire-resistant solutions to protect the timber from destruction and the effect of fire on it, which are characterized by the high efficiency of the penetration of these solutions into the middle of the timber, the durability of their protection and operational properties to ensure the longevity of the operation of timber structures. One of these fire-resistant solutions is a solution invented on the basis of the method of impregnation of timber based on area.

The curing system for newly developed solid state fire safe epoxy resins using dicyandiamide (DICY) was introduced. Composites of epoxy resins obtained from diglycidyl ether of 1,1-dichloro-2,2bis(4-hydroxyphenyl)ethylene bisphenol-C (BPC) and bisphenol-A (BPA) epoxy resins in the reaction with BPC and BPA and DICY hardener were studied. Solid epoxy resins were synthesised by the use of two different heating methods: conventional and microwave reactor. The quantities of DICY additions were 0.5–5.0 %, optimum was found to be 3 %.
