Abstract

The invention discloses an anti-corrosion fiber board and a preparation method for the same. The fiber board comprises a moulding additive, zirconium oxide fibers, a thickener, a defoamer, a filler, aluminum silicate fibers, a binder, a stabilizer, titanium carbide and dibromocyanoacetamide. The preparation method includes the steps of: a) cutting the zirconium oxide fibers and the aluminum silicate fibers and adding the cut fibers into a reactor; b) successively adding the titanium carbide, the stabilizer, the binder, the filler, the moulding additive, the thickener, the defoamer and the dibromocyanoacetamide into the reactor to carry out a reaction for 50-60 min to prepare a pre-mixture material; and c) mixing and stirring the pre-mixture material with water, allowing the mixture to stand to prepare a fiber board blank body, and drying the fiber board blank body to prepare the fiber board. The fiber board has excellent mechanical performance, strong anti-corrosion performance, excellent high-temperature stability and high strength. In preparation of the fiber board, addition sequence of the raw materials is reasonably adjusted, so that the method improves the strength of the fiber board and is environment-friendly and pollution-free.
