Preparation and Characterization of Phenolic Foam Modified by Nitrile Butadiene Rubber Powder

摘要

Phenolic-Formaldehyde (PF) foam was improved by co-foaming of PF resin modified using Nitrile Butadiene Rubber Power (NBRP) and other additives in the closing mould at 70°C. The effects of amount of NBRP on mechanical properties and microscopic structure of NBRP-PF foam were investigated. The results indicated that NBRP can improve the mechanical properties. When 2 percent NBRP of foam was used, the comprehensive performance was the best. This could be a consequence of cooperation of NBRP and PF resin.
