DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a method of manufacturing a humidity control plate material corresponding to the inventions according to claims 1 to 4, and this embodiment is shown below.

In the method for manufacturing a humidity control plate material of the present invention, rock wool is used as a main material 1 and a moisture absorbing / releasing material 2 that absorbs and releases moisture is mixed to form a wet mat 4 and the wet mat 4 is formed. 4 is impregnated with the phenol resin 6 from the surface 5 and then dried and cured to manufacture the humidity control plate material 10.

The method for producing the humidity control plate material of the present invention will be described in detail below.

A wet mat 4 is formed by mixing rock-wool 1 as a main material with a moisture absorbing / releasing material 2 that absorbs and releases moisture, and forms the wet mat 4 with a reticulated paper making machine 3 or a Hasek type paper making machine. Phenol resin 6 is uniformly dropped from the surface 5 of the mat 4 by a flow coater 7, and the phenol resin 6 is impregnated into the substrate of the wet mat 4 by depressurizing the suction box 8 and then dried in a dryer 9. The humidity control plate material 10 is manufactured by being cured.

At this time, the moisture absorbing / releasing material 2 which absorbs and releases moisture
Is a mixture of at least one of activated carbon, silica gel, zeolite, allophane, and diatomaceous earth.

The amount of the moisture absorbing / releasing material 2 added is 1 to 20 per weight of the dried substrate after drying, that is, the humidity control plate material 10.
% Is preferably blended. Because the added amount is 1%
If it is less than 20%, the humidity control effect cannot be obtained, and if it exceeds 20%, the water resistance is deteriorated and the required performance cannot be satisfied as a whole of the inner wall or ceiling material.

Further, the specific gravity of the molded humidity control plate material 10 is composed of rock wool as a main material and a moisture absorbing / releasing material in which at least one kind of activated carbon, silica gel, zeolite, allophane and diatomaceous earth is mixed. Phenolic resin is used as a binding material for rock wool and moisture absorbing / releasing material. Therefore, if it is set to 0.4 to 0.6, the weight can be reduced and the sound absorption, humidity control, deodorant, moisture resistance and bending can be achieved. It is possible to form a material having high strength. If this specific gravity range is less than 0.4, it has appropriate voids, but the flexural strength decreases, as well as moisture resistance and deodorant properties, and if it exceeds 0.6, a plate with high flexural strength is formed, but the basic performance is That is, the humidity controllability and sound absorption are deteriorated, which is also against weight reduction. (Example 1)

The rock wool board is impregnated with a phenol resin, and the moisture absorbing / releasing material 2 is mixed with an additive as a humidity control component and the moisture absorbing / releasing property is evaluated by absorbing moisture under the moisture absorbing condition of the base material. The amount and the amount of moisture released under the condition of moisture release were evaluated as shown in Table 1 below. Moisture absorption condition: 25 ° C 50% RH → 40 ° C 90% RH 24
h Moisture release condition: 40 ° C 90% RH → 25 ° C 30% RH 24
h As the additive composition, as shown in Example 2, activated carbon 10
%, Moisture absorption 220g / m when blended to a specific gravity of 0.4
2, the amount of moisture released was -245 g / m2, and excellent results of the humidity control effect were obtained. In addition, as shown in Example 3, moisture absorption amount 142 g / m 2 and moisture release amount -130 in the case of adding 5% zeolite and 10% allophane as an additive and having a specific gravity of 0.6
It was g / m2, and a good result of the humidity control effect was obtained. Further, the addition of 10% allophane, 10% diatomaceous earth, 5% allophane and 10% diatomaceous earth to the phenolic resin-impregnated rockwool board also provided good results for the humidity control effect. By the way, the moisture absorption amount is 70 g when the additive is added to the base material in the specific gravity of 0.5 as in the comparative example.
/ m2, moisture release amount -80 g / m2, the moisture absorption amount of the present invention increases by 30% or more of the comparative example, and the moisture release amount also increases by 30% or more.

Therefore, the specific gravity of 0.4 is obtained by using the phenol resin as the binder in the rock wool and the moisture absorbing / releasing material.
When it is set to ˜0.6, it is possible to reduce the weight and to form an interior building material having high sound absorption, humidity control, deodorization, moisture resistance and bending strength.

[Table 1] In addition, as shown in claim 5, FIGS. 2 to 3 comprise a moisture absorbing / releasing material 2 in which rock wool is used as a main material 1 and at least one kind of activated carbon, silica gel, zeolite, allophane, and diatomaceous earth is mixed. The humidity control plate member 10 is formed by forming pin holes 11 on the surface of the main body of the humidity control plate member which is made of a phenol resin 6 as a binder.

The pin hole 11 is formed on the surface of the rotating roll 12 as shown in FIGS. 4 (a) and 4 (b), as shown in FIGS.
It is embedded with a cylindrical shape, a nail shape, a conical shape like (c),
The surface of the humidity control plate material 10 is perforated by the rotational force of the rotary roll 12. At this time, the addition amount of the moisture absorbing / releasing material 2 is preferably 1 to 20% based on the weight of the dried substrate after drying, that is, the humidity control plate material 10. This is because if the amount added is less than 1%, the humidity control effect cannot be obtained, and if it exceeds 20%, the water resistance deteriorates and the required performance cannot be satisfied as a whole for the inner wall or ceiling material. A small hole penetrating the inside of the base material is provided on the surface of the humidity control plate material 10 in order to impart a humidity control function, and the diameter is 0.1 to 5
The tip may be inclined at mm. At this time, the depth of the pin hole 11 is 1 mm or more and 1 of the thickness of the base material.
/ 2 is possible. Further, a plurality of pins may be used to make holes at the same time, and the number of holes per surface is not particularly limited. Since the hole is made by pressing the surface of the substrate with the rotating roll 12 having a pin, it is preferable to make the hole before coating. By providing these pin holes 11,
Since the surface area of the base material is large, it is possible to impart high humidity control performance.

The specific gravity of the base material is preferably 0.4 to 0.6 as a specific gravity range for having appropriate voids and high air permeability. When the specific gravity is lower than this range, the physical properties such as bending strength are deteriorated, and when the specific gravity is higher, the air permeability is decreased and the humidity control effect is decreased.

At this time, the surface finish of the substrate is preferably a breathable finish, and a paint finish and a breathable cloth pasting finish are effective. (Example 2)

Specific examples will be given below. The moisture absorbing / releasing material 2 was added to the rock wool board impregnated with the phenolic resin, and the surface hole shape, the additive composition of the humidity controlling component and the moisture absorbing / releasing property were evaluated by the moisture absorbing amount and moisture releasing under the moisture absorbing condition of the base material. The amount of moisture released under the conditions was evaluated as shown in Table 2 below. Moisture absorption condition: 25 ° C 50% RH → 40 ° C 90% RH 24
h Moisture release condition: 40 ° C 90% RH → 25 ° C 30% RH 24
h Humidity control performance was evaluated. As an additive composition, as shown in Example 2, activated carbon 10
%, A specific gravity of 0.4, and when the pin hole 11 using the shape 2 of FIG. 5B is formed, the moisture absorption amount is 240 g / m 2.
2, the amount of moisture released was -265 g / m 2, and excellent results of the humidity control effect were obtained. In addition, as shown in Example 3, the moisture absorption amount 162 g / m 2 and the moisture release amount −150 in the case of adding 5% zeolite and 10% allophane as an additive and having a specific gravity of 0.6.
It was g / m2, and a good result of the humidity control effect was obtained. Further, the addition of 10% allophane, 10% diatomaceous earth, 5% allophane and 10% diatomaceous earth to the phenolic resin-impregnated rockwool board also provided good results for the humidity control effect. By the way, the moisture absorption amount is 70 g when the additive material is 0 and the specific gravity is 0.5 without pin holes as in the comparative example.
/ m2, moisture release amount -80 g / m2, the moisture absorption amount of the present invention increases by 50% or more of the comparative example, and the moisture release amount also increases by 50% or more.

Therefore, the weight can be reduced by setting the specific gravity to 0.4 to 0.6 by using the phenol resin as the binding material for the rock wool and the moisture absorbing / releasing material and providing the pin hole 11 on the surface. In particular, it is possible to form an interior building material having excellent sound absorbing properties, humidity controllability, deodorant property, moisture resistance and bending strength.
