Description of the Related Art Ceramic-based building materials such as fiber reinforced cement boards and gypsum boards are generally easy to absorb water, and the tendency is greater especially for lightweight foam concrete building materials and ceramic-based building materials with low specific gravity such as gypsum board. When such a building material absorbs water, it naturally discharges water and then releases moisture, but by repeating this, the building material warps, swells, or shrinks, and if the degree is large, the building material will crack or crack. . Further, in cold regions, the absorbed water freezes, causing frost damage. For this reason, conventionally, the front and back surfaces of building materials have been coated with waterproof paint, or
As disclosed in Japanese Patent Publication No. -16384, a water repellent is added to a compounding material to form a building material, and Japanese Patent Publication No.
As disclosed in Japanese Patent Laid-Open Publication No. JP-A-2003-13898, the water absorption of a building material is suppressed by, for example, compounding a porous aggregate in which a water repellent is adsorbed in the compound material.

あった。[Problems with the prior art] However, waterproofing by painting cannot be expected to be completely waterproof because the coating film itself has some water permeability, and if the building material is cut at the construction site, water absorption from the cut surface should be prevented. There was a problem that disappeared.
With respect to the water repellent adding means, when calcium stearate is directly added to the compounding material, the product strength may decrease depending on the adding means, and the above-mentioned JP-B-60-16384.
In the case of the method disclosed in the publication, it is necessary to once dry the molded body to a considerably high degree, and there is a problem that the manufacturing is troublesome.

However, there was a problem that it could not be implemented and was not versatile. Furthermore, since all of the water repellents disclosed in the above publications are calcium stearate, mineral oil, etc., there is a drawback in that the surface of the building material becomes slightly dirty due to the exudation of these water repellents, which makes it unsightly.

ある。According to a second aspect of the present invention, there is provided a method for producing a water-repellent ceramic building material, wherein a raw material having a small contribution to strength is mixed in a silicone water repellent emulsion and uniformly mixed, and then taken out. Then, after filtering so that the water repellent becomes 0.08 to 0.4% by weight based on the total amount of the compounded material, add the other compounded material and the required amount of water, mix and stir, mold, and cure after the primary curing in an autoclave. It is characterized by that.

Or it is supported by coating and mixed in the tissue. Therefore, during the hydration reaction of the tissue, the water repellent agent is not extremely dispersed in the tissue, so that the hardening reaction of the tissue is not hindered by the water repellent agent, and the primary curing is performed. Then, the water repellent is eluted to some extent by the heat during the curing of the autoclave performed thereafter, and is dispersed in the tissue. The elution at this time is efficient when the carrier raw material is not dried.

好適である。In the above, as a raw material with little strength contribution among the compounding materials for the ceramic building materials, lightweight foam aggregates such as pearlite and vermiculite, some silica sand or fly ash in the compounding material, calcium carbonate, fluidized bed ash There are other additives. Among the above, the lightweight foam aggregate absorbs the water repellent in the porous structure and is therefore suitable as the water repellent carrier.

まりなく、経済的に無駄となるからである。Further, the amount of the water repellent added is set in the range of 0.08 to 0.4% by weight based on the total amount of the compounded materials, if the amount is less than 0.08% by weight, the water repellent effect is not sufficiently exhibited, while 0.4% by weight is obtained.
This is because even if the amount is increased, the water repellent effect is not so much improved relative to the amount added, and it is economically wasted.

れる。The reason why the silicone water repellent is used as the water repellent is that there is almost no deterioration during autoclave curing and the water repellent effect tends to be improved.
The cause is not clear, but when calcium stearate or mineral oil is used as the water repellent, the water repellency is significantly reduced by autoclave curing, whereas the silicone water repellent shows such an adverse effect. Because I can't. The amount of the water-repellent agent added is adjusted so that the water-repellent agent has such a blending amount when dried.

料に転移付着するのが防止される。According to a first aspect of the present invention, as a means for supporting the water repellent agent on the carrier raw material, a required amount of the water repellent agent and the carrier raw material are mixed and used as a compounding material. In the second aspect, the carrier raw material is immersed in the emulsion liquid of the water repellent. By this immersion, the water repellent agent is uniformly and surely supported on the carrier raw material. Excessive water repellent is removed by filtering the emulsion liquid. Therefore, when mixing all the blended materials, the water repellent is prevented from transferring and adhering to other raw materials.
