Synthesis of bromo‐cardanol novolac resins and evaluation of their effectiveness as flame retardants and adhesives for particleboard

ABSTRACT The synthesis of bromo derivatives cardanolic novolac resins (BCNR) using infrared, thermogravimetric analysis, differential scanning calorimetry, gel permeation chromatography, nuclear magnetic resonance 1H and 13C methods was studied. The mechanism of thermal degradation of BCNR is propos...

Description
Summary:ABSTRACT The synthesis of bromo derivatives cardanolic novolac resins (BCNR) using infrared, thermogravimetric analysis, differential scanning calorimetry, gel permeation chromatography, nuclear magnetic resonance 1H and 13C methods was studied. The mechanism of thermal degradation of BCNR is proposed. It is shown, that particleboards manufactured using PU‐(BCNR) as an adhesive are materials with enhanced flame retardant properties, meeting the requirements of P7 class to EN 312 (especially durable moisture‐resistant particleboards) and the requirements of the emission class Super E0. The bromine in the structure of the cardanol‐containing polyurethane binder allows achieving both high physical and mechanical characteristics of the particleboards and resistance to flame. © 2017 Wiley Periodicals, Inc.
