充分な硬さや強度が与えられない。However, when the porous body is made of a hydrophobic material such as polyurethane foam, the impregnated synthetic resin emulsion does not spread throughout the porous body due to the water-repellent action of the hydrophobic material, resulting in uneven impregnation and porosity. The mass cannot be given sufficient hardness and strength as a structural material.

に硬化性を与えるかまたは硬化触媒を添加してもよい。The above-mentioned porous body is soft and lacks moldability and hardness as it is, and therefore cannot be used as a structural material such as a base material for an automobile interior. Therefore, in the present invention, moldability and hardness are imparted to the porous body by impregnating it with a synthetic resin emulsion. As the synthetic resin emulsion, an acrylic resin emulsion, an epoxy resin emulsion, a polyester resin emulsion, etc. are used. Desirably, the synthetic resin constituting the emulsion is hard with a glass transition point of 40°C or higher, and is heated to 150°C or lower. Alternatively, it is desirable to cure at room temperature. The above synthetic resin may be given curability or a curing catalyst may be added.

には合成樹脂が含浸されていることが望ましい。The synthetic resin emulsion used in the present invention usually has a solid content of about 30 to 60 parts by weight, and the organic solvent is usually 5 parts by weight per 100 parts by weight of such synthetic resin emulsion.
About 40 parts by weight of the synthetic resin emulsion mixed with the organic solvent is usually impregnated in an amount of about 50 to 300 parts by weight, preferably about 100 to 250 parts by weight, per 100 parts by weight of the porous body. After impregnation, it is heated to room temperature or a predetermined temperature to dry, and in the case of a curable synthetic resin emulsion, it is cured. When molding the above-mentioned porous body, the curable synthetic resin is subjected to hot pressing or the like before being hardened or in a semi-hardened state, so that it is completely hardened during molding. However, when the crosslinking density of the synthetic resin is low, even after complete hardening, the porous body can be hot-pressed or softened by heating and then subjected to cold-pressing, vacuum forming, etc. Glass ## on both sides or one side of the above synthetic resin-impregnated porous body! Inorganic fiber layers such as fiber layers, carbon fiber layers, organic fiber layers such as polyester fiber layers, cotton fiber layers, etc. may be stacked, and it is desirable that the fiber layers are impregnated with synthetic resin. .

質体の乾燥速度が大きくなる。When an organic solvent is mixed into a synthetic resin emulsion, even if the material constituting the porous body is hydrophobic, the synthetic resin emulsion has good wettability with the material, and the synthetic resin emulsion is uniformly impregnated into the porous body. . If the organic solvent mixed into the synthetic resin emulsion forms an azeotrope with water, the drying rate of the porous material impregnated with the synthetic resin emulsion increases.
