Abstract
Description
次に、具体的な実施例を例に挙げて本発明についてより詳細に説明する。ただし、以下の実施例は、本発明の範囲を限定することを意図するものではないことに留意されたい。
比較例1における木材の処理方法では、前工程と、含浸工程と、乾燥工程と、が行われた。すなわち、比較例1における木材の処理方法は、前述した実施例で説明した不溶化工程は行われていないことを除き、実施例と同様である。
比較例2における木材の処理方法は、実施例とほぼ同様な方法で行われた。ただし、不溶化剤として水酸化カルシウム溶液を用いる代わりに、不溶化剤として塩化カルシウム飽和水溶液が用いられた。
Claims (3)
- 酸性又は中性のリン酸系の難燃剤を木材に含浸する含浸工程と、
少なくとも前記木材の表層の前記難燃剤を不溶化剤によって不溶化させる不溶化工程と、を含み、
前記不溶化剤は、水酸化カルシウムを含む、木材の処理方法。 - 前記難燃剤は、ポリカルボン酸が添加されたリン酸グアニジンを含む、請求項1に記載の木材の処理方法。
- 前記ポリカルボン酸は、コハク酸である、請求項2に記載の木材の処理方法。
