Glass wool
The invention belongs to the technical filed of thermal insulation, and particularly to a glass wool. The glass wool comprises a plurality of glass fibers, and nanometer nanoparticles are attached to the surface of the glass fibers; the nanoparticles include nanometer SiO2; the mean grain size of the nanoparticles is within the range from 0 to about 100 nm; and the weight of the nanoparticles is less than or equal to 20% of the weight of the glass fibers. According to the glass wool, the nanoparticles are attached to the surface of the glass fibers in the glass wool, surface contact between glass fibers in the present glass wool is changed into point contact between nanoparticles, thermal conduction of the glass wool can be distinctly reduced, so that the glass wood has a low heat conduction coefficient. Compared with the present glass wool, the thermal insulation effect of a thermal insulation board made from the glass wool provided by the invention can be distinctly improved at the same thickness.
