Abstract
Description
本発明は、火山噴出物または火山噴出物発泡体を使用して簡便に得られ、調湿や有害物質の吸着のために使用される機能性材料組成物及びその製造方法に関する。 The present invention relates to a functional material composition that is easily obtained using a volcanic ejecta or a volcanic ejecta foam, and is used for humidity conditioning or adsorption of harmful substances, and a method for producing the same.
近年、世界規模で地球温暖化抑制に関する取り組みが不可欠になってきている。企業や各自治体などにより二酸化炭素などの排出を最小限に抑える技術が次々に開発されているが、当該排出をゼロにする技術は未だ開発されていない。
また住宅や工場、店舗などから排出される二酸化炭素や有害物質を吸着分解し、排出を軽減するため、また耐用年数を短くする住宅の高気密性能による冬場の結露が原因のカビや木造・金属の腐食等を軽減するために、無機物で、軽量の断熱および吸音能力を併せ持つ、調湿能力の高い製品の需要が高まっている。
In recent years, efforts to control global warming have become indispensable on a global scale. Technologies for minimizing the emission of carbon dioxide and the like have been developed one after another by companies and local governments, but a technology for reducing the emission to zero has not been developed yet.
Also, mold, wood and metal caused by dew condensation in winter due to high airtightness of houses to reduce emissions by adsorbing and decomposing carbon dioxide and harmful substances emitted from houses, factories, stores, etc. In order to reduce corrosion and the like, there is an increasing demand for products that are inorganic and have high moisture conditioning capacity that have both lightweight insulation and sound absorption capability.
このような需要に対しては、木炭・竹炭・ヤシガラ炭・活性炭などを含有する床下や屋根裏・クローゼットに適用する調湿剤が主流になっている。また調湿の他に有害物質の吸着を兼ね備えた製品なども多様に開発されている。
木炭・竹炭・ヤシガラ炭・活性炭などは古くから住宅の調湿剤として使用されているが、調湿効果は一様になく、木炭、竹炭は焼く温度によりその効果のばらつきが多いのが難点である。木炭・竹炭・ヤシガラ炭・活性炭などは二酸化炭素の吸着・分解効果は殆どなく、ホルムアルデヒド等の吸着の能力も少ないし、吸着の限界まで達したときには飽和状態になり、暑い時期には吐き出してしまうのもある。またこれらは、断熱性能が殆ど期待できない。住宅で使用される木炭・竹炭・ヤシガラ炭・活性炭などの調湿剤は万一火災の発生があった場合には、調湿剤に着火し、延焼の原因にもなることから、危険性なども指摘されている。
In order to meet such demands, humidity control agents applied to under floors, attics, and closets containing charcoal, bamboo charcoal, coconut husk charcoal, activated carbon, and the like have become mainstream. In addition to humidity conditioning, a variety of products have also been developed that also adsorb harmful substances.
Charcoal, bamboo charcoal, coconut husk charcoal, activated carbon, etc. have been used as humidity control agents for homes for a long time, but the humidity control effect is not uniform, and the charcoal and bamboo charcoal have many variations depending on the baking temperature. is there. Charcoal, bamboo charcoal, coconut husk charcoal, activated carbon, etc. have almost no carbon dioxide adsorption / decomposition effect, have little ability to adsorb formaldehyde, etc., and reach the limit of adsorption, become saturated, and exhale in hot weather There is also. In addition, they can hardly be expected to have heat insulation performance. Humidifiers such as charcoal, bamboo charcoal, coconut husk charcoal, and activated carbon used in houses should ignite the humidifier and cause fire spread in the event of a fire. Has also been pointed out.
一方、軽量で高い強度の火山噴出物発泡粒子集塊物が断熱材、保温材や吸音材として使用されることが知られている（特許文献１）。当該集塊物は火山噴出物発泡体とケイ酸ソーダ水溶液との混合物を、強制的にＣＯ２を接触させることで、硬化させて得られ、ケイ酸ソーダは水溶液の形態に限定され、空気中のＣＯ２と接触させないことが必要とされている。そのため、これらの製造にはプレス機や炭酸ガスの吹き込み装置の設備が必要とされ設備投資が過大になり、製造コストが高くなっている。他方、火山噴出物又は火山噴出物発泡体と珪酸アルカリ水溶液を混合・攪拌した後、ＣＯ２を強制的に吹き込み、反応させた材料を使用することを特徴としている特許文献２では、その材料から出来た製品は既にＣＯ２吸着機能を、ほぼ終えているために、吸着機能を失っていること、作業工程が複雑になることに加え、複雑な工程を経るために、その設備が必要になり、製造コストが高くなる。また、火山噴出物発泡粒子と珪酸ソーダ濃厚水溶液の混練物中に、炭酸ガスを反応させた材料に、ポリビニルアルコール水溶液とカルボシキメチルアルコールおよび酢酸ビニルアルコール樹脂エマルジョンを混合した成形体は、表面を爪で掻くと剥がれやすく、強度が弱いということが知られ、より強度の高い材料が求められている。また何れも、ＣＯ２を強制的に吹き込み、反応させることで得られる火山噴出物発泡粒子集塊物の製造過程で、ＣＯ２が外部に漏れ出すために地球環境にも問題が生じる（特許文献１、２）。
そのため簡便に製造でき二酸化炭素吸着・揮発性有機化合物（ＶＯＣ）吸着や調湿機能を有する材料の開発が望まれている。
On the other hand, it is known that a lightweight and high-strength volcanic ejecta foam particle agglomerate is used as a heat insulating material, a heat insulating material, and a sound absorbing material (Patent Document 1). The agglomerates are obtained by curing a mixture of volcanic ejecta foam and sodium silicate aqueous solution by forcibly contacting CO 2, and sodium silicate is limited to the form of an aqueous solution. Is not required to come into contact with CO 2 . For this reason, a press machine and a carbon dioxide blowing device are required for these productions, resulting in excessive capital investment and high production costs. On the other hand, after mixing and stirring the volcanic ejecta or the volcanic ejecta foam and the alkali silicate aqueous solution, CO 2 is forcibly blown and the material reacted is used in Patent Document 2, characterized in that Since the finished product has already almost completed the CO 2 adsorption function, it has lost the adsorption function, the work process becomes complicated, and the equipment is required to go through the complicated process. , Manufacturing costs are high. In addition, a molded body in which a mixture of a volcanic product foamed particle and a concentrated aqueous solution of sodium silicate mixed with carbon dioxide gas is mixed with a polyvinyl alcohol aqueous solution, a carboxymethyl alcohol and a vinyl acetate alcohol resin emulsion. It is known that when it is scratched with a nail, it is easily peeled off and its strength is weak, and a material with higher strength is required. Also both forcibly blowing CO 2, in the manufacturing process of volcanic ejecta foamed particle agglomerates obtained by reacting, CO 2 is also a problem occurs in the global environment to leak out (Patent Documents 1, 2).
Therefore, it is desired to develop a material that can be easily produced and has a carbon dioxide adsorption / volatile organic compound (VOC) adsorption and humidity control function.

平均粒子径は各メッシュ毎に篩い分けられた粒子の試料全体に対する割合（重量％）を算出し、各メッシュ毎の割合（重量％）を上段から足していき、５０％超えになる前の数値を[ｄ]、５０％超えになる数値を[ｅ]とし、５０％超えにならないメッシュのアンダー値（μｍ、ｍｍ）を[ａ]とする。そして、５０％超えになるメッシュを特定し、そのメッシュのオーバー値（μｍ、ｍｍ）を[ｂ]、アンダー値を[ｃ]として、下記式（Ｉ）より重量平均粒子径を求めた。
平均粒子径（μｍ、ｍｍ）＝ａ−〔（ｂ−ｃ）×{（５０−ｄ）／ｅ}〕・・（Ｉ）
