Abstract
【解決手段】フラン樹脂に硬化剤とともに過酸化物を添加することで、成形体の表面及び内部が均一に硬化可能となる熱硬化性樹脂組成物および硬化方法であり、過酸化物が過酸化水素水、過炭酸ナトリウム、過酸化酢酸、過硫酸アンモニウム、過硫酸カリウム、過硫酸ナトリウム、次亜塩素酸、及び亜塩素酸から選ばれ、フラン樹脂100質量部に対して0.01質量部以上5質量部未満である。
【選択図】なし
Description
また、PBS(Poly Butylene Succinate)は、現在は石油由来の原料が用いられているが、今後においては、植物由来樹脂として作製する研究が開発されており、主原料の一つであるコハク酸を植物由来で作製する技術についての開発がなされている。
そのため、一度に厚膜を形成しようとする場合は内部の樹脂成分は硬化不足となる。また、金型内で板状の成形体を成形すると内部だけでなく表面の酸素の供給も制限され、樹脂が硬化不足となり高強度の成形物を得ることは困難であるという問題があった。
(1) フラン樹脂、硬化剤、及び過酸化物を含有する熱硬化性樹脂組成物。
(2) 過酸化物が過酸化水素水、過炭酸ナトリウム、過酸化酢酸、過硫酸アンモニウム、過硫酸カリウム、過硫酸ナトリウム、次亜塩素酸、及び亜塩素酸から選ばれる1種以上のものである(1)に記載の熱硬化性樹脂組成物。
(3) 過酸化物の含有量がフラン樹脂100質量部に対して0.01質量部以上5質量部未満である(1)または(2)に記載の熱硬化性樹脂組成物。
(4) フラン樹脂に過酸化物を添加することを特徴とするフラン樹脂の硬化方法。
(5) (1)〜(3)のいずれかに記載の熱硬化性樹脂組成物を加熱加圧下で硬化するフラン樹脂の硬化方法。
本発明で用いるフラン樹脂はフラン環を有する樹脂であればよいが、フラン樹脂として現在産業化されているものはフルフリルアルコールを主原料としたものである。フルフリルアルコールの原料は、ヘミセルロースを含む植物原料であるコーンコブ、バガス、籾殻が代表的なものである。これらを無機酸の存在下で加熱すると、五炭糖が生成し、さらに脱水反応を経てフルフラールとなる。フルフラールは蒸留にて分離され、さらに水素添加することでフルフリルアルコールを得ることができる。このフルフリルアルコールを初期縮合したものがフラン樹脂であり、常温で褐色かつ液状の樹脂である。

フラン樹脂(日立化成工業株式会社製、VF−303)180gに対し、硬化剤としてp−トルエンスルホン酸0.945gと34.5質量%の過酸化水素水1.26g(フラン樹脂100質量部に対して過酸化水素0.24質量部)を添加し、混合後に真空脱泡して熱硬化性樹脂組成物を得た。
ステンレス製の金型(縦横200mm、深さ2mm)に離型剤(ナガセケムテックス株式会社製、Mould Release Agents QZ 13)を塗布した後、前記熱硬化性樹脂組成物を金型に充填した。その後加熱プレス装置に金型を設置し、20MPaの圧力にて、30℃で2時間、65℃で3時間、115℃で4時間、最後に145℃で4時間加熱加圧し、フラン樹脂を含む成形体を得た。
(曲げ試験)
前記成形体を幅25mm、厚み2.0mm、長さ60mmに切り出し、試験片とした。試験片を少なくとも5本作製し、曲げ試験を実施した。インストロン型万能試験機(株式会社島津製作所製 オートグラフ、AGS-J)を用い、ヘッド速度を1.0mm/min、支点間距離を40mmとして前記試験片の3点曲げ試験を行った。5本の試験片の曲げ強度と曲げ弾性率の平均値を表1に示す。
配合する過酸化水素水の量を2.07g(フラン樹脂100質量部に対して過酸化水素0.40質量部)とした以外は実施例1と同様の方法で熱硬化性樹脂組成物の調製、熱硬化物の成形、曲げ試験を実施した。得られた曲げ強度及び曲げ弾性率の平均値を表1に示す。
配合する過酸化水素水の量を4.50g(フラン樹脂100質量部に対して過酸化水素0.86質量部)とした以外は実施例1と同様の方法で熱硬化性樹脂組成物の調製、熱硬化物の成形、曲げ試験を実施した。得られた曲げ強度及び曲げ弾性率の平均値を表1に示す。
配合する過酸化水素水の量を6.10g(フラン樹脂100質量部に対して過酸化水素1.17質量部)とした以外は実施例1と同様の方法で熱硬化性樹脂組成物の調製、熱硬化物の成形、曲げ試験を実施した。得られた曲げ強度及び曲げ弾性率の平均値を表1に示す。
過酸化水素水を配合しない以外は実施例1と同様の方法で熱硬化性樹脂組成物の調製、熱硬化物の成形、曲げ試験を実施した。得られた曲げ強度及び曲げ弾性率の平均値を表1に示す。
