Bromo-cardanol-novolac resins as adhesives for particleboards

Wednesday, 5 July 2017

In a study, researchers have demonstrated the efficacy of bromo-cardanol-novolac resins as adhesives for particleboards. In addition, they discovered another important advantage of the binders.

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.

Enhanced flame retardant properties

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.

The study is published in: Applied Polymer Science, Vol. 134, Issue 38.
