丁腈橡胶粉改性酚醛树脂泡沫的性能与微观结构研究
Properties and Microstructure of Phenolic Foam Modified by Nitrile Butadiene Rubber Powder
摘要
Abstract
The performance of phenolic-formaldehyde(PF) foam was improved by co-foaming of PF resin with nitrile butadiene rubber power(NBRP) and other additives in the closing mould at 70 ℃.The influence of NBRP modification method including pre-NBRP and post-NBRP on the properties of phenolic foams was studied.The effects of amount of pre-NBRP modification on mechanical properties,fragile properties,flame-retardant properties and microscopic structure of NBRP-PF foam were further investigated.The results indicated that the pre-NBRP-modified PF foam had better properties compared with that of Post-NBRP,when 2 ％ NBRP was used.The overall performance of PF foam was the best.This could be a consequence of cooperation of NBRP and PF resin.关键词
