    Abstract：Aiming at the high added value application of blast furnace slag fiber，selecting the appropriate concentration of PVA solution，using different concentration glutaraldehyde modified polyvinyl alcohol solution to product the new binder of blast furnace slag fiber. By testing its bulk density，moisture absorption rate and acid alkali resistance and other indexes to determine the glutaraldehyde concentration in the new binder. The results show that the optimum solution of the new binder for the preparation of blast furnace slag fiber insulation board is 5% polyvinyl alcohol solid content of glutaraldehyde to modify 3% polyvinyl
alcohol.
