[実施例8]
床面積約25mの部屋の床全面に床コンパネを2枚重ね貼りし、仕上げに樹脂床材とクッションフロアを半々に貼り付けた。床材用接着剤は、東リ株式会社製エコAR600を使用した。さらに、部屋の壁面および天井に、接着剤でパーティクルボードを貼り付けた。接着剤は、ホルムアルデヒド法規制対象外のFフォースター品を使用した。
施工2、3、4、5日後に、室内のホルムアルデヒド濃度をホルムアルデヒド検知管(株式会社ガステック製、No.91D)で調べた結果、何れも2ppmであった。
その後、壁面および天井のパーティクルボードに竜山石粉末(粒径250μm以下)を含むスラリー[塗り壁材、竜山石含有量500g/m、バインダー:非水溶性メチルセルロース(竜山石100gに対し3g)]を塗布し、塗り壁を形成した。塗り壁形成1日後に、室内のホルムアルデヒド濃度をホルムアルデヒド検知管で調べた結果、0ppmであった。
[Example 8]
Two floor control panels were laminated on the entire floor of a room with a floor area of about 25 m 2 , and a resin floor material and a cushion floor were attached in half to finish. Eco AR600 manufactured by Toli Corporation was used as the flooring adhesive. In addition, particle board was attached to the walls and ceiling of the room with an adhesive. The adhesive used was an F Forster product that is not subject to formaldehyde regulations.
As a result of examining the formaldehyde concentration in the room with a formaldehyde detector tube (manufactured by Gastec Co., Ltd., No. 91D) 2, 3, 4, and 5 days after the construction, all of them were 2 ppm.
After that, a slurry containing Ryuzan stone powder (particle size 250 μm or less) on the particle board on the wall surface and ceiling [plaster wall material, Ryuzan stone content 500 g / m 2 , binder: water-insoluble methyl cellulose (3 g per 100 g of Ryuzan stone)] Was applied to form a plaster wall. One day after the formation of the plaster wall, the indoor formaldehyde concentration was examined with a formaldehyde detector tube and found to be 0 ppm.

[実施例9]
竜山石の粉末(粒径500μm以下)100gとチタンアパタイト(太平化学産業株式会社製)3gを、非水溶性メチルセルロース3g及び水100gと混合した。この混合液は、分離することなく、均一に混ざっていた。この混合液をパーティクルボード(30cm角)の片面にコテで塗布し、塗膜を形成した。塗膜は、ひび割れすることなく、きれいな塗り壁となった。この塗り壁は、優れた消臭効果ならびに耐カビ性を有し、霧吹きで水をかけたところ、十分な吸水性を有していた。さらに、空気浄化、水浄化、汚れ分解、抗菌、殺菌等の機能を付与できた。
[Example 9]
100 g of Tatsuyama stone powder (particle size 500 μm or less) and 3 g of titanium apatite (manufactured by Taihei Kagaku Sangyo Co., Ltd.) were mixed with 3 g of water-insoluble methyl cellulose and 100 g of water. This mixed solution was uniformly mixed without separation. This mixed solution was applied to one side of a particle board (30 cm square) with a trowel to form a coating film. The coating film became a clean plaster wall without cracking. This plastered wall had an excellent deodorizing effect and mold resistance, and when sprayed with water, it had sufficient water absorption. Furthermore, functions such as air purification, water purification, dirt decomposition, antibacterial, and sterilization could be added.

実施例1〜9に示すように、流紋岩質溶結凝灰岩を含むことで、アンモニアやホルムアルデヒドといった臭いを吸収する、優れた消臭効果を有した耐カビ消臭剤とすることが出来た。ペット臭についても同様である。実施例1に示すように、本発明の耐カビ防臭剤では、30分後〜長時間経過後も消臭効果が持続され、驚異的な消臭効果、臭い分解効果が判明した。また、実施例2に示すように、本発明の耐カビ消臭剤は大量の臭いの消臭が可能であり、消臭効果が持続する。このため、臭いを分解していると考えられる。さらに、実施例3〜6に示すように、流紋岩質溶結凝灰岩粉末にポリマー系の接着剤を混合して成形体にした場合でも、臭いを吸収する効果が実証された。 As shown in Examples 1 to 9, by containing rhyolite welded tuff, it was possible to obtain a mold-resistant deodorant having an excellent deodorizing effect that absorbs odors such as ammonia and formaldehyde. The same applies to pet odors. As shown in Example 1, the antifungal deodorant of the present invention maintained the deodorizing effect even after 30 minutes to a long time, and it was found that the deodorizing effect and the odor decomposition effect were astonishing. Further, as shown in Example 2, the antifungal deodorant of the present invention can deodorize a large amount of odor, and the deodorizing effect is maintained. Therefore, it is considered that the odor is decomposed. Further, as shown in Examples 3 to 6, even when a polymer-based adhesive was mixed with rhyolite welded tuff powder to form a molded product, the effect of absorbing odor was demonstrated.

(2) Mold resistance evaluation [Example 10]
Place rice and black mold on the surface of a particle board coated with Tatsuyama stone powder, put it in a cup containing 30 g of water, seal it with a resin film at a humidity of 50 to 80% or more, and leave it for 21 days. did. As a result, as shown in FIG. 1, black mold propagated on the surface.
The propagated black mold was wiped off with a tissue paper, and the surface condition was visually confirmed. As shown in FIG. 2, the black mold could be easily wiped off.

[比較例3]
竜山石の粉末を塗布したパーティクルボードに代えて、何も塗布していないパーティクルボードとした以外は、実施例10と同様にして、パーティクルボードの表面に米と黒カビを配置し21日間放置した。この結果、図3に示すように、表面に黒カビが繁殖した。
繁殖した黒カビをティッシュペーパーで拭き取り、表面の状態を目視で確認した。図4に示すように、黒カビが定着していたため拭き取ることが出来なかった。
[Comparative Example 3]
Rice and black mold were placed on the surface of the particle board and left for 21 days in the same manner as in Example 10 except that the particle board coated with Tatsuyama stone powder was replaced with a particle board to which nothing was applied. As a result, as shown in FIG. 3, black mold propagated on the surface.
The propagated black mold was wiped off with a tissue paper, and the surface condition was visually confirmed. As shown in FIG. 4, the black mold had settled and could not be wiped off.

実施例10に示すように、流紋岩質溶結凝灰岩を含むことで、耐カビ性の高い耐カビ消臭剤とすることが出来た。また、竜山石の粉末自体には、カビは発生しなかった。 As shown in Example 10, by containing rhyolite welded tuff, it was possible to obtain a mold-resistant deodorant having high mold resistance. In addition, no mold was generated on the powder of Tatsuyama stone itself.

本発明の耐カビ消臭剤は、耐カビ性が高く、優れた消臭効果を有した耐カビ消臭剤として使用できる。また、本発明の成形体によれば、カビの定着性が低く、耐カビ性に優れ、かつ優れた消臭効果を有する成形体を提供できる。

The mold-resistant deodorant of the present invention can be used as a mold-resistant deodorant having high mold resistance and an excellent deodorizing effect. Further, according to the molded product of the present invention, it is possible to provide a molded product having low mold fixability, excellent mold resistance, and an excellent deodorizing effect.
