Abstract
【解決手段】 充填構造体10は、中空部材11の内部に衝撃エネルギーの吸収性能に富む充填材12を挿入し、この充填材12を、加熱により膨張させ、その後硬化させた接着層13により、中空部材11に固定してなる構造体である。
【効果】 接着剤は膨張する過程で充填材の表面に密着する。充填材の表面に多数の孔があっても接着剤は充填材に良好に接合する。
【選択図】 図1
Description
また、寒冷地では路面凍結対策として融雪塩を散布するが、このような環境、すなわち充填材と中空部材との間に融雪塩を含んだ水などが浸入する腐食環境では、特に鋼板製の中空部材に適切な防錆処理(化成処理や電着塗装)を施さないと鋼板部材に腐食が発生し内部からの腐食進行により穴明き錆へと進行する可能性がある。
さらにまた、無処理鋼板とアルミ製充填材の接触により異種金属接触腐食が発生し、アルミ製充填材に著しい機能劣化を起こす可能性がある。
ここでいう接着剤とは、接着性を有する高分子樹脂を指し、例えばエポキシ系接着剤、ウレタン系シール剤などが挙げられる。
この結果、中空部材に充填材を強固に固定することができる。
図1は本発明に係る充填構造体の断面図であり、充填構造体10は、内面に防錆処理層11aを施した中空部材11の内部に衝撃エネルギーの吸収性能に富む充填材12を挿入し、この充填材12を、加熱により膨張させ、その後硬化させた接着層13により、中空部材11に固定してなる構造体である。
充填材12は、嵩密度が0.6g/cm3程度の発泡アルミニウムが好適である。
この結果、接着層13の存在により、充填材12を強固に中空部材11に固定することができる。
図3は本発明の充填構造材の製造フロー図である。
(a)において、中空部材11を準備する。中空部材11は、例えば1.7mm厚さのアルミニウム合金押し出し材(A6063−T5)である。
(b)において、充填材12を準備する。
(c)において、充填材12にシート状接着剤17・・・を貼り付ける。
隙間18が存在するため、中空部材11に簡単にシート状接着剤17付き充填材12を挿入することができたと言える。
図示しないが、この状態の中空部材11等を防錆処理工程に装入し、防錆処理を施す。このときに防錆処理液は隙間18を通過するため、中空部材11の外面及び内面に均等に防錆処理を施すことができる。
そして、乾燥炉に入れて、140℃〜190℃の温度で10分〜30分間加熱する。この加熱により塗膜が乾燥し硬化するとともに、シート状接着剤17が、溶融し、且つ膨張し、その後の冷却により硬化する。この過程でシート状接着剤17は10%以上体積膨張し、隙間18に充満する。
請求項2では、接着剤は液状/固体状、固体である場合にシート状/粉末状の何れでも良い。
