Abstract
The invention relates to a preparation method of a phosphate-reinforced zirconia fiber high-efficiency thermal-insulation composite material, and belongs to the technical field of inorganic composite material preparation. The preparation method comprises following steps: 1, pretreatment of zirconia fiber; 2, preparation of a phosphate binder; 3, preparation of a thermal-insulation composite material molding slurry; 4, pumping filtration moulding; and 5, heat treatment. Operation of the preparation method is simple; the obtained target product can be used at 1500 DEG C for a long term; intensity is low; high temperature stability is high; and the mechanical properties of the obtained phosphate-reinforced zirconia fiber high-efficiency thermal-insulation composite material are improved greatly.
