Abstract
Description
本出願は、2018年1月5日に出願された米国仮特許出願第62/614,038号、および2018年3月5日に出願された米国仮特許出願第62/638,859号の各々に関し、その優先権および利益を主張するものであり、これらの各々の開示全体は、参照により本明細書に組み込まれる。
本明細書に記載される特定の実施例は、難燃性および騒音低減性の両方を提供する複合物品に関する。
LWRTシートを湿式堆積法を使用して生成した。LWRTシートは、ポリオレフィン系、例えば、ポリプロピレン系であり、チョップドガラス繊維を使用して強化された。ポリプロピレン樹脂とガラス繊維とを水中で混合し、均一な懸濁液に撹拌した。懸濁液を成形ワイヤ上に堆積させ、水を除去して、ポリプロピレン樹脂およびガラス繊維を含むウェブを形成した。樹脂を熱溶融してさらに処理すると、ウェブが加圧下で樹脂の融点未満の温度まで冷却された後、固体の複合コアが形成される。
LWRTシートを実施例1で精製されたものと同様に形成したが、難燃剤を樹脂とチョップドガラス繊維との混合物に添加した。膨張性グラファイト(EG)および水酸化マグネシウム(MDH)を含む2つの異なる難燃性材料を使用した。両グレードとも、ASTM E84法によって試験される際、クラスA要件に適合し、1つのグレードは、SAE J369法によって試験される際、SE−0要件に適合する。
実施例2のウェブの形成後で、最終コア形成前に、様々な材料を実施例2から形成されたコアに追加した。材料をウェブの両側面に適用した。表1および2は、特定の試験済みLWRT物品に存在する様々な材料および添加剤を列記する。
面積密度、灰分、生成時の厚さおよびロフティング厚さを含む物理的特性を、99mmの直径を有するディスクを使用して測定した。音響性能を試験するために、2つの試験標準に従った。ASTM E1050に従って、材料の両方のグループを評価し、表1のグループAの材料も、建築および建設用途の潜在的な使用のために、ASTM C423−17法に従って試験した。SAE J369およびASTM E84法に従って、燃焼性試験を実施した。SAE J369は、自動車用途においてより一般的である、一方ASTM E84法によって試験される性能は、オフィス家具ならびに建築および建設産業によって期待される性能についてのより深い洞察を提供する。加えて、材料の曲げ強度も、ASTM D790またはISO 178法に従って試験した。
試料A1、A2、A3、B1、およびB2の燃焼性能を、ASTM E84試験標準を使用して試験した。ASTM E84標準では、クラスA性能は、25以下である火炎伝播指数(FSI)および450以下である煙発生指数(SDI)を必要とする。材料を熱成形プロセスなしで試験した。試験されたすべての材料は、表5に示されるようにクラスA要件に適合する。
対照Bおよび試料B3を、これらの材料が自動車用途に使用され得るように、熱成形後にSAE J369法に対しても試験した。試料B3は、自己消火性能力を示した。成形された材料は、成形時およびモーターオイルに10分間浸漬した後で、SE−0レベルの性能を示す。図26A(上側)および26B(下側)は、燃焼性試験後の試験片の例を示す。試験片を、最初に5W30エンジンオイルに10分間浸漬し、垂直にして20分間排液した。試験片をエンジンオイルが豊富な端部から点火した。それは自己消火し、図26Aおよび26Bに示されるように、わずかな損傷のみが点火端部で発生した。
対照Aおよび試料A3の曲げ強度測定値が図27で比較され、図28は、対照B、試料B1、および試料B2の曲げ強度測定値を比較する。材料を、縦方向(MD)および幅方向(CD)の両方において試験した。LWRTの機械的強度は、ガラス繊維および樹脂によってより決定される。両方の種類の添加剤は、一般に複合体の機械的強度を低下させるとみなされる。EGはより効果的なFR添加剤であるため、曲げ強度は、EGバージョンのLWRTであまり影響を受けない、これは、添加剤のより低い投入レベルの結果であり得る。
