(Industrial Application Field) The present invention relates to a multifunctional composite material body. (Prior Art) As a conventional deodorizing/liquid absorbing composite material body, there is a composite material body developed by the present inventor. (Unexamined Japanese Patent Publication No. 1983-
No. 147468). This composite material body is made by impregnating a water-absorbing support such as nonwoven fabric or paper pulp with a deodorizing liquid, and then laminating multiple sheets of this support. In addition to scattering the agent, a waterproof sheet is attached to the lower surface, and the upper layer is in the support.
It consists of a stabilized chlorine dioxide adsorbent and a moisture absorbing/dispersing agent such as silica gel. This composite material body deodorizes bad odors from corpses, etc.
It has multiple functions such as maintaining the freshness of vegetables, sterilization, and excellent water absorption. However, due to insufficient gas absorption capacity,
There was a problem that the sustainability of the freshness-keeping ability of vegetables etc. was slightly inferior. (Object of the Invention) Therefore, the inventor conducted extensive research to solve the above problems and came up with the present invention. That is, the purpose of the present invention is to absorb moisture,
Excellent water absorption, deodorization, insect repellency, and mold resistance, especially deodorization,
An object of the present invention is to provide a multifunctional composite material body that has an excellent ability to maintain the freshness of vegetables and the like. (Means for Solving the Problems) In the multifunctional composite material according to the present invention for the above-mentioned purpose, a water-absorbing material made of sodium polyacrylate is combined with a support such as a non-woven fabric having breathability and water-absorbing properties. On the support side of the first laminated sheet body interspersed with a water-impermeable perforated breathable film,
An inorganic porous powder made of hydrated magnesium silicate mineral and having a large number of elongated tunnel-shaped pores arranged in a cross-sectional matrix is interposed between two supports such as non-woven fabrics having air permeability and water absorption properties. It is characterized by having a laminated sheet body attached to it. It is preferable to impregnate it with at least one of hinokitiol, hinoki oil, and wasabi extract. (Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings. 10 is a first laminated sheet body. This first laminated sheet body 10 has a support body 12 made of non-woven fabric, split fiber, etc., which has breathability and water absorption properties, and a support body 12 having air permeability and water absorption properties, and a support body 12 having air permeability and water absorption properties. A water-absorbing agent 16 made of sodium polyacrylate is interspersed between a perforated breathable film 14 made of polyolphene or the like. Support body 12 and perforated breathable film 1
4 is joined by heat sealing. In addition, the support body 12 may be provided in two layers of nonwoven fabric or the like, and the water absorbing agent may be interspersed between them. It is best to keep sodium polyacrylate in a form that is insoluble in water, similar to those used as food additives. The amount of sodium polyacrylate mixed is 25 per m2 .
~30g is suitable. 18 is a second laminated sheet body. This second laminated sheet body 18 has a large number of elongated tunnel-shaped holes between two supports 20 and 22 made of a nonwoven fabric having breathability and water absorption, or a coarse resin split fabric. is formed by interposing inorganic porous powder 24 arranged in a cross-sectional matrix shape. To form this second laminated sheet body 18, a small amount of organic binder is mixed into the inorganic porous powder 24,
It is preferable to sandwich and press the support bodies 20 and 22 together. The inorganic porous body 24 is made of a hydrous magnesium silicate mineral having a crystal structure as illustrated in FIG.
The cross-section of the single fiber has a structure in which talc is stacked alternately (Figure 3), and the fiber has a structure in which there are many tunnel-like holes with a diameter of about 5.6 x 11.0 Å in a matrix. . The structural formula of hydrated magnesium silicate shown in Figure 2 is (Mg 8 ) [Si 12 ]
It is represented by O 30 (OH) 4 (OH 2 ) 4 8H 2 O. Although it looks similar to asbestos, asbestos is made up of rolled talc crystals.
It has a completely different structure. Because it has these tunnel-like pores, it has gas absorbency that is about 60 times greater than maifan stone, and it also has a unique adsorption ability to adsorb odor components. Further, the inorganic porous powder 24 has gas absorbing properties and water absorbing properties, and retains or releases these. In addition to this inorganic porous powder 24, inorganic powder such as silica gel, maifan stone, activated carbon, etc. may be mixed. The amount of inorganic porous powder 24 mixed is per 1 m 2
About 150g is good. The second laminated sheet body 18 is attached to the upper surface of the support 12 of the first laminated sheet body 10 using an adhesive 26.
Paste together using As the adhesive for bonding the nonwoven fabrics together, a rubber adhesive is preferable. Furthermore, rather than applying the adhesive over the entire surface, it is preferable to apply the adhesive partially in a mesh shape or the like so that water and moisture can pass through. Also, since the adhesion between non-woven fabrics cannot be achieved very well, it is recommended that non-woven fabrics be bonded together using an adhesive sheet with adhesive applied to both sides of a mesh-like synthetic resin sheet, as shown in Figure 4. By doing so, the two can be bonded well. When using the multifunctional composite material body constructed as described above, it is preferable to store it in an external decorative cover 28 made of light and soft nonwoven fabric. Next, the functions will be explained. Moisture, moisture, odorous gas, etc. from the outside are partially absorbed by the external decorative cover 28 and the supports 20, 22, and most of them pass through and reach the inorganic porous powder 24, where they are collected. As mentioned above, the inorganic porous powder 24 has a structure in which a large number of pores in the form of long and narrow tunnels are arranged in a cross-sectional matrix, and has a gas absorbency approximately 60 times that of Maifan stone. The odorous gas is absorbed by the body powder 24, and its odorous components are adsorbed on the inner wall of the tunnel-like cavity, and the odorous gas is released as odorless. Furthermore, since the inorganic porous powder 24 has excellent ethylene gas absorption properties, it is effective in maintaining the freshness of vegetables, fruits, and the like. Usage: vegetables,
It can be used by directly wrapping fruits, etc., or by placing them in a storage container. Furthermore, as will be described later, it is also excellent in absorbing moisture from vegetables, fruits, etc. Moisture or moisture once absorbed by the inorganic porous powder 24 is eventually released, passes through the supports 22 and 12, and is absorbed by the water absorbing agent 16. Sodium polyacrylate has an extremely high absorbency of about 2.4/m 2 . In the case of silica gel, it absorbs rapidly, but when it is saturated with moisture, it loses its ability to absorb moisture completely and releases only a small amount of absorbed moisture. Therefore, it is not possible to expect much moisture adjustment effect. On the other hand, sodium polyacrylate can quickly and in large quantities absorb moisture and water introduced from the upper part, and also has a certain degree of dissipation ability, so it also has an appropriate humidity control ability. Table 1 shows the moisture absorption rates of this composite material (Example) and silica gel.

Because of its excellent water absorbency, it can be effectively used for wall materials to prevent condensation. For example, 40℃, 1
When m2 of air reaches 0℃, 1m2 of ceiling surface has approx.
This results in 117g of condensed water, but this composite material body has about 20 times the water absorption capacity, and its water absorption and water retention capacity is about 2400g per 1 m2. 5.7~ when converted to siligakel
Equivalent to 6.4Kg. Furthermore, by making sodium polyacrylate insoluble in water, the growth of mold can be effectively prevented. In the case of water-soluble sodium polyacrylate, mold is thought to grow due to residual nutrients because the starch is subjected to craft polymerization of sodium acrylate. Since the perforated permeable film 14 does not allow moisture to pass through, the moisture absorbed by the sodium polyacrylate does not leak to the outside. On the other hand, since it has air permeability and moisture permeability, it does not impair the above-mentioned humidity control properties and also contributes to preventing stuffiness in stored items. It is preferable to impregnate the above composite material with hinokitiol, hinoki oil, or wasabi extract. Since these have insect repellent and bactericidal effects, they can be made into more multifunctional composite material bodies.
