Disclosed are a barium titanate foam ceramic/thermosetting resin composite material and a preparation method therefor. An organic additive is used as an auxiliary; deionized water is used as a solvent; nanometer barium titanate is used as a ceramic raw material; and all of same are mixed and ground so as to form a slurry with a certain solid content. A pre-treated polymer sponge is impregnated into the slurry for slurry coating treatment, and then redundant slurry is removed and the polymer sponge is dried so as to obtain a barium titanate foam ceramic blank, and same is then sintered so as to obtain a barium titanate foam ceramic. A resin, being in a molten state and thermosettable, submerges the pores of the barium titanate foam ceramic, and a barium titanate foam ceramic/thermosetting resin composite material is obtained after a thermosetting treatment.

An exterior sheathing cementitious panel which prevents water penetration and air leakage is provided methods for manufacturing exterior sheathing cementitious panels with a highly efficient integrated air/water barrier membrane are provided as well.

In a method of preparing a modified barium titanate foam ceramic/thermosetting resin composite material, an organic additive is used as an auxiliary; deionized water is used as a solvent; nanometer barium titanate is used as a ceramic raw material; and these components are mixed and grounded to form a slurry. A pre-treated polymer sponge is impregnated in the slurry for slurry coating treatment and a barium titanate foam ceramic is obtained after drying and sintering. Then, through dopamine modification, micrometer/nanometer silver is deposited in situ on a skeleton surface. A resin, which is in the molten state and is thermosettable, is immersed into pores of the modified barium titanate foam ceramic, and the modified barium titanate foam ceramic/thermosetting resin composite material is obtained after a thermosetting treatment.
