发布时间：2019-01-04 21:33
【摘要】：玻璃纤维纸是一种优良的阻燃保温隔音过滤材料,在高铁、航空航天和航海领域有广泛的应用。本文通过湿法打浆工艺制备不同纤维混合的玻璃纤维纸,重点探究其孔径分布、透气性能、保温性能以及隔音性能。结果表明:随着玻璃纤维纸中细纤维含量的增加,平均孔径和透气率先减小后增加;随着玻璃纤维纸中细纤维含量的增加,纸张的导热系数先降低后升高,隔音量先升高后降低。纤维配比为粗纤维50%+细纤维50%,玻璃纤维纸的保温隔音性能最佳。
[Abstract]:Glass fiber paper is a kind of excellent flame retardant, insulation and sound filter material, which has been widely used in the fields of high-speed, aerospace and navigation. In this paper, glass fiber paper with different fibers was prepared by wet beating process, and its pore size distribution, air permeability, heat preservation and sound insulation were investigated. The results show that the average pore size and air permeability decrease first and then increase with the increase of the content of fine fiber in glass fiber paper. With the increase of the content of fine fiber in glass fiber paper, the thermal conductivity of paper first decreases and then increases, and the sound insulation content increases first and then decreases. Fiber ratio is 50% coarse fiber fine fiber 50, glass fiber paper insulation sound insulation performance is the best.
