MESOPOROUS GLASS FIBER AND PREPARATION METHOD THEREFOR AND GRADED POROUS FIBER COTTON AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2022/257359

A1

The present invention relates to the field of glass fibers, and in particular to a mesoporous glass fiber and a preparation method therefor and graded porous fiber cotton and a preparation method therefor. The diameter of the glass fiber is 0.25 μm-5 μm, and the glass fiber has a mesoporous structure, and has good heat insulation and sound insulation effects. The graded porous fiber cotton comprises a resin adhesive and the mesoporous glass fiber. The glass fiber cotton is good in porosity, contains a mesoporous and microporous graded pore structure, and is low in heat conductivity coefficient and excellent in sound insulation and heat insulation performance, the lowest heat conductivity coefficient of the glass fiber cotton can reach 0.015W/(m·K), a fire resistance grade is A1 grade, and the highest loss of 2000 Hz of sound transmission can reach 2.1 dB.
