FLY ASH-DOPED GLASS FIBER CORE MATERIAL AND PREPARATION METHOD THEREOF
(Figure 1) The present disclosure discloses a fly ash-doped glass fiber core material and a preparation method thereof. In the core material, a high alkali glass fiber is used as a matrix which accounts for 60%-70% by mass. A binder is coated among the fibers, and the binder is silicon oxide or sodium silicate and accounts for 5%-10% by mass. Fly ash is doped in a pore among fibers, and the fly ash has a particle size of 100-300 mesh and accounts for 25%-30% by mass. In the present disclosure, a glass fibre felt is prepared by a wet process, and a silane coupling agent is sprayed onto a surface of the glass fibre felt uniformly during a drying process. After curing, a vibration fly ash adding machine is placed above the glass fiber core material, and fly ash particles are added into the glass fiber core material in such a way that the fly ash particles are uniformly distributed in the pores among fibers. The rigidity is greatly enhanced after doping with fly ash, which effectively solves the problem, i.e., when a surface internal barrier film is damaged, the core material in the traditional vacuum insulation panel quickly absorbs air and rebounds because of its great elasticity, thereby causing further damages to the structure thereof, and greatly prolongs the service life of the vacuum insulation panel. - 1/1 Figure 1
