Description
例えば、1.顔料を含む樹脂中に混入して顔料に対する濡れ及び分散性を増加させ、顔料の含有量を増加させる樹脂着色助剤として、2.PVC(塩化ビニル樹脂)押出射出成型カレンダー加工における滑剤として、3.スチレン系・PVC等の熱可塑性樹脂、フェノールポリウレタン等の熱硬化性樹脂の成型時にドライブレンドまたは練込みに添加する離型剤として、4.印刷インキに混入して耐磨耗性を向上や鮮明度上昇剤として、5.ペイント中に混入して顔料の分散向上や、顔料の沈降防止用等と様々な分野で用いられている。
即ち、この樹脂系改質剤製造装置は、図1に示すように、ワックス状物質溶融物を溜めておく有底円筒状の受溜用タンクTが、タンク上端開口部1bを有し、かつ、支脚1aによって支持されて設けられている。
この結果、表1の実施例1に示すように、密度0.934g/cm3(JISK6922-2試験法)、粘度2353mPa・s(B型,140℃試験)、融点108.7℃(DSC,-60⇔150℃(2回目昇温時測定))、融解熱量138.0J/g(同左測定)、軟化点114.0℃(JISK2207試験法)、針入度0mm(JISK2207試験法)、油分0wt%(JISK2235試験法)、全酸価3.4mg-KOH/g(JISK5902試験法)、引火点306℃(JISK2265試験法)の特性の樹脂系改質剤が得られた。即ち、この燃焼熱分解により全酸価0mg-KOH/g(JISK5902試験法)を3.4mg-KOH/gに改質させることができた。
一方、油分の変化は、高分子量(分子量100,000以上)のポリエチレンが、熱分解によって低分子量のポリエチレン(分子量 2,000〜10,000程度)へと分解され、その一部が更に分解し油状(分子量 数百以下)のものが副生成物として生成したことを示すものである。
