摘要：应用丁腈橡胶粉(NBRP)对酚醛树脂进行改性,再与其他助剂复合在70℃制备改性酚醛泡沫材料。分析了NBRP的改性方式对酚醛泡沫材料性能的影响,进一步讨论了NBRP前期改性加入量对酚醛泡沫机械性能、易碎性能、燃烧性能和泡孔微观结构的影响。研究表明:NBRP前期改性酚醛泡沫性能优异,其中添加量2%时综合性能最佳,这为丁腈橡胶粉改性酚醛树脂提供了科学依据。
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.
