た。However, since the above-mentioned conventional heat insulating material mixes and presses each component in a dry manner, it is difficult to mix them uniformly in a dispersed state, and the heat insulating property of the obtained heat insulating material is low. There was a problem of being insufficient. Further, since the dry pressing is performed, there is a problem that the ceramic fiber is broken at the time of pressing, and the resulting heat insulating material has a small bending strength and compressive strength. Furthermore, in the dry press,
Since it is difficult to accurately form a heat insulating material having a complicated shape, there is a problem that post-processing is required.

ましい。The inorganic fiber used in the present invention is required to have an average fiber diameter of 5.0 μm or less. This is because if the average fiber diameter is larger than 5.0 μm, the voids become large when formed into a molded product, the thermal conductivity becomes high, and the fibers collapse when compressed to a predetermined density and the strength decreases. .
As such an inorganic fiber, silica / alumina ceramic fiber, alumina fiber, silica fiber, sepiolite or the like is used. Non-fibrous particles, which are usually called shots, are contained in the inorganic fibers, but it is desirable that these shots do not fulfill the function as fibers and the thermal conductivity becomes high. For example, since the silica / alumina ceramic fiber or the like usually contains 50% by weight of shots of 44 μm or more, it is preferable to forcibly remove the shots in advance to reduce the shots of 44 μm or more to 20% or less.

It is in the range of 40% by weight. If this ratio is less than 10% by weight, suppression of radiant heat, which is one factor that influences heat insulation,
In particular, it cannot scatter infrared rays, and if it is blended in an amount of more than 40% by weight, the blending ratio of the inorganic fibers is relatively reduced, the bulk density of the obtained molded article is increased, and the heat insulating property is deteriorated. Become.

ある。The average particle size of titanium oxide is 0.4 μm.
It is necessary to be the following. This is because if the average particle size exceeds 0.4 μm, the voids of the obtained molded product become large, the effect of preventing air convection is not sufficiently exhibited, and the thermal conductivity becomes high. Further, in the present invention, it is necessary to add a colloidal inorganic binder in order to maintain the strength of the obtained molded product in the low to medium temperature range. The colloidal inorganic binder is easily dispersed uniformly in the solvent and is easily fixed uniformly. The addition amount of the colloidal inorganic binder needs to be in the range of 1 to 10% by weight. If the addition amount is less than 1%, the strength of the obtained molded product will be insufficient, and if it is more than 10%, the molded product will lose its flexibility and become brittle, and the thermal conductivity will increase due to conduction heat transfer. Because. 3-5% is suitable.

Latex such as SBR, and horiaxol amide generally used as a paper strengthening agent are used. The main purpose of the organic binder is handleability of the molded product at room temperature, cushioning property, and processability, and it is added as necessary, but the addition amount is preferably 3 to 5%. The bulk density of the obtained heat insulating agent is in the range of 0.2 to 1.0 g / cm 3 in terms of heat conduction. If it is less than 0.2 g / cm 3 , convection or radiation will be large, and if it exceeds 1.0 g / cm 3 , conduction will be large.

First, the ceramic fibers are stirred in a dispersion medium such as water to form a slurry, titanium oxide is added to this and mixed by stirring, and further a colloidal inorganic binder and, if necessary, an organic binder are added and mixed by stirring. . The mixed slurry is wet-molded, that is, suction-molded into a mold having a predetermined shape to mold a desired molded body. The obtained molded product is dried to obtain the desired heat insulating material. In the above heat insulating material, inorganic fibers, titanium oxide, and an inorganic binder prevent convection of air inside the heat insulating material, and titanium oxide scatters radiation of heat, so that the bulk density is within a predetermined range. , The convection of air in the voids existing inside the heat insulating material and the conduction of heat through the solid portion of the heat insulating material are suppressed, and the reflection of heat rays at the surface layer of the heat insulating material on the heat source side is promoted. Is estimated to improve.

Moreover, since the inorganic fibers are uniformly present throughout the heat insulating material and form a three-dimensional network structure, it is presumed that the bending strength and compressive strength of the heat insulating material can be improved. Next, examples and comparative examples embodying the present invention will be described.

It is presumed that this is because each component is uniformly dispersed by a wet method and then wet-molded as it is, so that fine air holes prevent convection of air, and titania scatters infrared rays to promote radiation. The bulk density is 0.2 to
It is in a suitable range of 0.5 (g / cm 3 ) and can prevent convection and radiation. Furthermore, the bending strength of the heat insulating material of Example 1 is about 5 times higher than that of Comparative Example 1, and the compressibility is 5
Since it is about 3 times higher at a load of 0 (kg / cm 2 ), it can be seen that the strength is improved accordingly.
