Description

【０００１】
【発明の属する技術分野】
住環境に於いて温湿調整が配慮された断熱及び騒音対策の重要性が今改めて見直しされている。木質及び昔の土壁構造の良さを目標とした構造である。最近の建築内装材・輸送機器内装材の多くは通気性のない材料が使用されており温湿調整は全て機械調整に依存されている。又使用している有機材料によるシックハウス問題もある。本発明は音及び湿気入射面になる表面材に通気性、芯層材に使用する材料に強度補うためのハニカム材とハニカム材のセル空間の欠陥を音・吸湿性・断熱性を持った発泡体の充填で補い複合化されたサンドイッチパネル構造の新しい製造技術である。この技術の応用範囲は建築・輸送機器の温湿調整及び防音領域の技術分野だけに止まらず省エネを含めた住環境対策分野の全範囲までが技術領域となる。
【０００２】
【従来の技術】
建築・輸送機器の内装分野ではアルミ等の金属材料類・セラミックス・プラスチック等の表面材に強度・断熱・防音性能を付加する芯材としてセル空間のハニカム材、スチレン・ウレタン等の合成樹脂系の発泡体材料を使用したサンドイッチパネルを採用する場合と断熱・防音対策を取れてない合板又は複合化粧板或いは金属板及び不燃性である石膏系の単板に化粧シートを貼っただけの内装材が一般的に使用されている。いずれの材料構成も通気及び吸湿対策が取られていず、むしろ仕切り内装パネルとして気密による防音・断熱設計に価値を高める配慮が優先されている材料構造になっている。従って内装構造は限りなく気密構造になっており、使用されている接着剤によるシックハウス問題、気密による結露及び乾燥環境の発生、結露から発生するカビ問題があり、その対策が問われている。最近は調湿機能の重要性が見直され、珪藻土の気泡構造を使用した製品開発がされているが本発明の材料構成である合成樹脂発泡体による使用例はない。
【０００３】
【発明が解決しようとする課題】
本発明は現在多く使用されている吸湿呼吸をしない内装新建材から発生してくるシックハウス・結露問題・断熱・防音対策等の問題課題を含む構造を古来型の土壁構造に近い発明構造により解決させる手段である。土壁構造は竹を編み土を塗った複合材で中に空気を残した防湿・防音・断熱材であり土による吸湿と温度調整効果もあり、分析すると多くの良さが発見できる材料構成にある。しかし材料及び工法・職人など時代の変わった現在はもう一度土壁工法の築造に戻すことは出来ない。従って気密構造とならない材料の発見と複合化方法を発明課題として吸湿・吸音・断熱特性を合せ持つサンドイッチパネル構造体及び製造方法としてまとめる。
【０００４】
【課題を解決するための手段】
土壁構造相当の本発明構造は音・湿気入射反対面層には金属・セラミックス・無機材・木材質材等から火災・防水・外観の好み及び法規制基準に応じ選択し、土壁部になる層は代替の手段として連通気泡を有し吸湿性を改善するため界面活性剤が処方され吸音・断熱・不燃特性を持つ密度３０ｋｇ／ｍ３以下のフェノールフォーム発泡体とフェノールフォームの強度を補うためハニカム材を使用した複合芯層材からなり、入射側面層には通気性のある繊維質・金属質・無機質・セラミックス質等の材料から好み・法規制基準に応じ選択して使い、複合芯層材と面材とのサンドイッチ化は入射反対側面材には面材の接着面にエポキシ又はウレタン系接着剤を塗布し強固に接着し、入射側面材との接着は通気性を遮断しないように１０〜１００ｍｍの一定間隔を維持した線状又は升目状に接着剤を塗布して三層を接着で一体化させたサンドイッチ構造を土壁構造に代わる解決の手段とした構造体としている。本発明での特徴となる製造方法は連通気泡フェノールフオームの脆さ及び強度不足を補うため使用するハニカム材をハニカム材のセル端面を工具のように使用し、機械加圧により荷重をかけハニカム材と同一寸法形状の連通気泡フェノールフォームを切断しフェノールフォームがハニカム材セルの中に充填され複合化された芯層材構造の採用と入射側の通気性面材の通気性を妨げない空気空間を保った接着方法にある。得られる構造は充填された連通気泡フェノールフォームの吸湿・吸音・断熱特性とハニカム材の軽さと強度が最大限に利用され土壁の性能を越える代替芯層材になった。吸湿力を高く要求される場合は界面活性剤の処方されたフェノールフォームを使用することも大変有効であることも実証実験で証明された。
【０００５】
【発明の実施の形態】
発明の実施の形態は音及び湿気入射反対側の面材にアルミ・カラー鉄板・セラミック等の耐水・防火材を選択し用い、土壁の代替になる壁芯層材に樹脂含浸のペーパー・アルミ・セラミックス質等の連通気泡フェノールフォームの強度不足を補うため使用するハニカム材から要求構造により材質を選んだハニカム材を使用し、ハニカム材セルの鋭い端面を工具のように使い、吸湿・吸音特性を持つ連通気泡フォームの密度３０ｋｇ／ｍ３以下でハニカム材と同一寸法形状のフェノールフォームを重ねて機械加圧を行い荷重をかけて切断しハニカム材セル空間にフェノールフォームが充填され複合化した芯層材を使用することを特徴とし、入射側面材は通気性のある繊維・アルミ・石膏質及び木質から選択する。実施のサンドイッチ構造の形態は入射反対面の材料として選択したアルミ面材との接着にエポキシ系の二液接着剤を４００〜６００ｇ／ｍ２の量を十分に混合撹拌し面材の芯層材との接着面に塗布し芯層材と強固に接着させ、通気性を持つアルミエキスパンドメタル材の入射側面材との接着は通気性を遮断しないようにシリコン系の一液性の接着剤を接着面の全面でなく空気が対流できる１０〜１００ｍｍの間隔で線状に使用に耐える接着量を塗布し芯層材と十分な接着をさせ、塗布した一液性のシリコン系の樹脂接着剤の硬化はフェノールフォームの連通気泡中の滞留空気と入射側面材の通気構造による空気対流による空気中の水分と接触反応させ硬化させることを接着の手段として製造されたサンドイッチパネル構造体。
【０００６】
【実施例】
図１はセルサイズ１２ｍｍの厚み３０ｍｍの樹脂含浸ペーパーハニカム材の鋭いセル壁端面を工具のように使用しハニカム材と同寸法形状で密度２３ｋｇ／ｍ３の界面活性剤が処方され吸湿性が改善された連通気泡フェノールフォームが切断されハニカム材セルに充填されたサンドイッチパネルの芯層材となる図である。図２は湿度及び音の入射面に使用する通気性を有するアルミエキスパンドメタル板にシリコン系一液接着剤を通気性を遮断しないよう３０ｍｍ間隔の線状にアルミエキスパンドメタル板の芯層材接着面に塗布した図である。図３は図１の連通気泡フェノールフォームが充填されたセルサイズ１２ｍｍの樹脂含浸ペーパーハニカム材芯層材の湿度・音入射反対面に使用した厚さ１ｍｍのアルミ材の芯層材との接着面の全面にエポキシ系接着剤を６００ｇ／ｍ２の塗布量を塗布し芯層材と強固に接着した状態と、湿度・音入射面である図２のアルミエキスパンドメタル板面の芯層材と接着する面にシリコン系一液性接着剤が３０ｍｍ間隔の空気空間を保った線状に塗布され芯層材と接着されサンドイッチパネルの形態になった図である。
【０００７】
【発明の効果】
内壁構造を想定し、吸湿効果を高めるためフェノールフォームに界面活性剤が介在した実施例構造パネルを温度１８℃湿度８０％の雰囲気に５時間放置すると吸湿効果によりパネルが面積当り３〜４％重量で増え、その後に温度１５℃湿度３０〜４０％の雰囲気に４８時間放置したら前の重量にもどり吸湿の呼吸効果が証明された。吸音効果については市場で多く使用されている硬質ウレタンフォーム充填のアルミサンドイッチパネルと比較し垂直入射吸音率において周波数と吸音率結果を確認した所、実施例構造パネルに５〜８倍の吸音効果があることが確認された。

TECHNICAL FIELD OF THE INVENTION
The importance of insulation and noise control with consideration for temperature and humidity in the living environment is now being reviewed again. The structure aims at the goodness of the woody and old mud wall structure. Most of the recent building interior materials and transportation equipment interior materials are made of non-breathable materials, and the adjustment of temperature and humidity all depends on mechanical adjustment. There is also a sick house problem due to the organic material used. The present invention is a foam having sound, moisture absorption and heat insulation properties by eliminating defects in the cell space of the honeycomb material and the honeycomb material for enhancing the strength of the material used for the core layer material. This is a new manufacturing technology for a sandwich panel structure that is supplemented by filling the body and compounded. The scope of application of this technology is not limited to the technical fields of temperature and humidity adjustment and soundproofing of construction and transportation equipment, but also covers the entire range of living environment measures including energy saving.
[0002]
[Prior art]
In the interior field of construction and transportation equipment, honeycomb materials for cell spaces and synthetic resin materials such as styrene and urethane are used as core materials to add strength, heat insulation and soundproofing to surface materials such as aluminum and other metal materials, ceramics and plastics. Sandwich panels using foam materials are used, and interior materials that only have a decorative sheet attached to a plywood or composite veneer or a metal plate and a non-combustible gypsum veneer that do not take heat insulation and soundproofing measures Commonly used. Neither material configuration takes measures against ventilation and moisture absorption, but rather has a material structure that prioritizes consideration for enhancing the value of soundproofing and heat insulation design by airtightness as a partition interior panel. Therefore, the interior structure is infinitely airtight, and there are sick house problems due to the adhesive used, dew condensation due to airtightness, generation of a dry environment, and mold problems caused by dew condensation. Recently, the importance of the humidity control function has been reviewed, and products using a diatomaceous earth cell structure have been developed. However, there is no example of using the synthetic resin foam which is the material composition of the present invention.
[0003]
[Problems to be solved by the invention]
The present invention solves the structure including problems such as sick house, dew condensation problem, heat insulation, soundproofing measures, etc., generated from interior building materials that do not absorb moisture and breathe, which are often used now, by the invention structure close to the ancient type earth wall structure. It is a means to make it. The mud wall structure is a composite material made of bamboo knitted soil and is a moisture-proof, sound-insulating, and heat-insulating material that leaves air inside.It also has the moisture absorption and temperature control effects of the soil, and has a material composition that can find many good points when analyzed. . However, with the changing times of materials, construction methods and craftsmen, it is not possible to return to the construction of the mud wall method again. Therefore, the discovery of a material that does not have an airtight structure and the method of compounding it are summarized as a sandwich panel structure and a manufacturing method having both moisture absorption, sound absorption, and heat insulation properties as an object of the invention.
[0004]
[Means for Solving the Problems]
The structure of the present invention, which is equivalent to the earth wall structure, selects the metal, ceramics, inorganic material, wood material, etc. on the opposite surface of the sound / moisture incidence according to the fire / waterproof / appearance preference and legal regulations, and As an alternative, the phenol foam having a density of 30 kg / m 3 or less and a phenol foam having a sound absorbing, heat insulating and non-flammable property and having sound absorbing, heat insulating and non-flammable properties are supplemented with a surfactant to improve the hygroscopicity by having open cells as an alternative means. Therefore, the composite core layer material made of honeycomb material is used, and the incident side layer is selected from breathable materials such as fibrous, metallic, inorganic and ceramic materials according to your preference and legal standards. The sandwich between the layer material and the face material is made by applying an epoxy or urethane-based adhesive to the adhesive face of the face material on the opposite side face material and firmly adhering it. 10-100m A sandwich structure in which an adhesive is applied in a linear shape or a grid shape maintaining a constant interval of m and three layers are integrated by bonding is used as a solution as a means to solve the earth wall structure. The manufacturing method which is a feature of the present invention uses a honeycomb material which is used to compensate for brittleness and insufficient strength of the open-celled phenol form, using a cell end face of the honeycomb material like a tool, applying a load by mechanical pressure, and applying a honeycomb material. The phenol foam is cut into the same size and shape of the open-cell phenol foam, and the phenol foam is filled in the honeycomb material cell to adopt a composite core layer material structure and an air space that does not hinder the air permeability of the incident side permeable face material It is in the bonding method that was kept. The structure obtained is a substitute core layer material that exceeds the performance of earth wall by making full use of the moisture absorption, sound absorption and heat insulation properties of the filled open-cell phenol foam and the lightness and strength of the honeycomb material. Demonstration experiments have shown that the use of a phenolic foam formulated with a surfactant is also very effective when high hygroscopicity is required.
