Description
軽量の木材材料により、例えば家具の梱包、輸送、解梱又は組立の場合に、エンドユーザーによる製品の取り扱いは簡単になる。軽量の木材材料により輸送コスト及び梱包コストは低下し、さらに軽量の木材材料の製造の際に材料コストも節約することができる。軽量の木材材料により、例えば輸送手段中で使用する場合に、前記輸送手段のエネルギー消費量を少なくすることができる。さらに、軽量の木材材料を使用することで、例えばキッチンにおいて現在流行している厚い作業ボード及び側面のような材料費用のかかる装飾部分を低コストで提供できる。
A) 充填剤の製造
A1.1) 帯電防止剤を備えた発泡可能なポリスチレンの製造
表1にまとめられている市販の発泡可能なポリスチレンを使用する。
発泡可能なポリスチレンを、例えばEP 981 574に記載されたと同様に製造した。製造の間又は製造後の帯電防止剤の添加は行わなかった。
実施例A1により得られたポリスチレン粒子を水蒸気で連続的予備発泡装置中で処理した。予備発泡されたポリスチレン球の嵩密度は、蒸気圧及び蒸気処理時間を変えることにより調節した。次の表1にまとめられた予備発泡されたポリスチレン粒子を製造した。
A3.1) 押し出されたポリスチレンフォーム(充填剤6)
Styrodur(R)としてBASF社から入手可能な押し出されたPSフォーム(嵩密度約30kg/m3)を、インパクトミル(Pallmann Prallmuehle Typ PP)中で平均粒径0.2〜2mmにまで粉砕した。
9cm×40cm×70cmのサイズの絶縁体用の、密度33kg/m3のリサイクルされた市販のポリウレタンフォームを、カッティングミル(Schneidmuehle Retsch SM2000)中で平均粒径0.2〜2mmにまで粉砕した。
B1) US 2005/0019548による木材材料
US 2005/0019548開示された特徴を、表2中にまとめた。(実施例1〜3)
B2) JP 06031708による木材材料
JP 06031708開示された特徴を、表2中にまとめた。(実施例4〜5)
B3) 充填剤あり及びなしの木材材料
B3.1) 使用材料の混合
ミキサー中で表2によるチップ又はファイバー450g及び場合により表2による充填剤を混合した。引き続き、Kaurit(R)-Leim 340 100部及び52%硝酸アンモニウム水溶液4部及び水10部からなる接着剤液剤58.8gを添加した。
接着剤を添加されたチップ又はファイバーを30×30cmの型中で冷間で予備圧縮した。引き続きホットプレス中でプレス成形した(プレス温度190℃、プレス時間210秒)。ボードの目標厚さはそれぞれ16mmであった。
C1) 密度
密度の測定は、製造後に24時間にEN 1058により行った。
前記横方向引張強さの測定は、EN 319により行われる。
膨潤値及び吸水率の測定は、DIN EN 317により行った。
