Abstract
本發明之聚胺酯樹脂係包含多元醇成分、異氰酸酯成分者,且(1)包含聚碳酸酯二醇成分作為上述多元醇成分,包含直鏈型脂肪族異氰酸酯成分作為上述異氰酸酯成分,(2)上述聚碳酸酯二醇成分之數量平均分子量為500~3000,於其結構中包含源自碳數3~10之二醇之結構,(3)上述異氰酸酯成分中10 mol%以上為碳數4~10之直鏈型脂肪族異氰酸酯成分。
Description
本發明係關於一種聚胺酯樹脂、塗料、構造物、及物品。
聚胺酯系樹脂其耐磨耗性、彎曲性、可撓性、柔軟性、加工性、接著性、耐化學品性等各物性優異,且對各種加工法之適應性亦優異,故而被廣泛用作合成人造皮(人工皮革與合成皮革之總稱)用材料、各種塗佈劑、油墨、塗料等之黏合劑、或膜、片材及各種成型物用材料,提出有適合各種用途之聚胺酯系樹脂。
例如,於合成人造皮之皮革樣片材之製造步驟中,為了提高質感,使用將聚胺酯樹脂成膜而成之膜。尤其是於用於車輛內飾材料等長期耐久消耗材之情形時,通常使用聚碳酸酯多元醇作為聚胺酯樹脂合成時所使用之多元醇(例如,參照專利文獻1)。
專利文獻1:日本專利特開2013-108196號公報
然而,於僅使用聚碳酸酯多元醇之情形時,所獲得之皮革樣片材存在雖耐光性優異,但彎曲性變差之情形。
尤其是未發現具有寒冷地區中之彎曲性即耐寒彎曲性之材料。
如上所述,要求寒冷地區中之彎曲性(耐寒彎曲性),另一方面,例如於如合成人造皮之柔軟之素材中,若欲提高耐寒彎曲性,則會導致耐化學品性降低。該情況會導致化學品容易滲透至影響彎曲性提高之樹脂骨架中,故而耐寒彎曲性與耐化學品性呈折衷關係。即,難以同時實現該等。
根據以上,本發明提供一種可同時實現優異之耐寒彎曲性及耐化學品性之聚胺酯樹脂。
本發明者等人進行努力研究,結果發現,使用具有特定數量平均分子量及結構之聚碳酸酯二醇,並以特定量包含異氰酸酯成分中碳數4~10之直鏈型脂肪族異氰酸酯成分之聚胺酯樹脂可解決上述課題,從而完成本發明。即,本發明如下所述。
[1]一種聚胺酯樹脂,其係包含多元醇成分、異氰酸酯成分者,且滿足下述(1)~(3)。
(1)包含聚碳酸酯二醇成分作為上述多元醇成分,包含直鏈型脂肪族異氰酸酯成分作為上述異氰酸酯成分。
(2)上述聚碳酸酯二醇成分之數量平均分子量為500~3000,其結構中包含源自碳數3~10之二醇之結構。
(3)上述異氰酸酯成分中10mol%以上為碳數4~10之直鏈型脂肪族異氰酸酯成分。
[2]如[1]所記載之聚胺酯樹脂,其係含有具有1個以上之活性氫基且具有親水基之化合物成分而成,且酸值為5~40mgKOH/g。
[3]如[1]或[2]所記載之聚胺酯樹脂,其中上述多元醇成分中之上述
聚碳酸酯二醇成分之比率為50質量%以上。
[4]如[1]至[3]中任一項所記載之聚胺酯樹脂,其中上述異氰酸酯成分中上述碳數4~10之直鏈型脂肪族異氰酸酯成分之比率為15mol%以上。
[5]如[1]至[4]中任一項所記載之聚胺酯樹脂,其進而包含短鏈二醇成分及/或短鏈二胺成分。
[6]如[1]至[5]中任一項所記載之聚胺酯樹脂,其中選自由上述多元醇成分、上述異氰酸酯成分、上述短鏈二醇成分、及上述短鏈二胺成分所組成之群中之至少1種包含源自植物之原材料。
[7]如[5]或[6]所記載之聚胺酯樹脂,其中上述短鏈二醇成分之比率以mol比計,相對於上述多元醇成分為0.1~3倍量。
[8]如[1]至[7]中任一項所記載之聚胺酯樹脂,其中上述聚胺酯樹脂之玻璃轉移溫度為-50~-10℃。
[9]如[1]至[8]中任一項所記載之聚胺酯樹脂,其中上述聚胺酯樹脂之tanδ之極大值於-40~-10℃之溫度範圍內。
[10]如[1]至[9]中任一項所記載之聚胺酯樹脂,其中膜化後之該膜之-10℃下之100%模數之物性值為20MPa以下。
[11]如[1]至[10]中任一項所記載之聚胺酯樹脂,其中膜化後之該膜於70℃下於油酸中浸漬24小時後之100%模數之物性值保持率為20%以上。
[12]一種塗料,其包含如[1]至[11]中任一項所記載之聚胺酯樹脂。
[14]一種構造物,其包含如[1]至[11]中任一項所記載之聚胺酯樹脂。
[15]一種構造物,其於表面及內部之至少任一者包含如[12]或[13]所記載之塗料。
[16]一種合成人造皮,其包含如[14]或[15]所記載之構造物。
根據本發明,可提供一種可同時實現優異之耐寒彎曲性及耐化學品性之聚胺酯樹脂。
以下,對本發明詳細地進行說明。再者,於本發明中,所謂聚胺酯樹脂,係聚胺酯樹脂及聚胺酯-脲樹脂之總稱。
[聚胺酯樹脂]
本發明之聚胺酯樹脂係包含多元醇成分、異氰酸酯成分者,且滿足下述(1)~(3)。
(1)包含聚碳酸酯二醇成分作為多元醇成分,包含直鏈型脂肪族異氰酸酯成分作為異氰酸酯成分。
(2)聚碳酸酯二醇成分之數量平均分子量為500~3000,其結構中包含源自碳數3~10之二醇之結構。
(3)異氰酸酯成分中10mol%以上為碳數4~10之直鏈型脂肪族異氰酸酯成分。
以下,對構成聚胺酯樹脂之各成分更詳細地進行說明。
[多元醇成分]
本發明中之多元醇成分包含聚碳酸酯二醇成分,作為成為聚碳酸酯二醇成分之聚碳酸酯二醇,使用至少數量平均分子量為500~3000且於其結構中包含源自碳數3~10之二醇之結構者。
此處,所謂「其結構中包含源自碳數3~10之二醇之結構者」,亦可謂水解時獲得碳數3~10之二醇之聚碳酸酯二醇,例如較佳為使用下述式(1)或式(2)所表示之聚碳酸酯二醇。
上述式(1)中之m為3~10,n為數量平均分子量成為500~3000之自然數。例如,下述實施例中所使用之ETERNACOLL UH-200(宇部興產製造)之m=6,數量平均分子量為2000左右,n之理論值成為13、14。

而,為了賦予設計性,將於表面處理層側雕刻有花紋形狀之壓紋輥於該表面被加熱(100~190℃)之狀態下抵接,藉此製成表面形成有花紋圖樣之合成樹脂表皮材(例如汽車用之座椅)(花紋圖樣形成步驟)。
再者,於將本發明之聚胺酯樹脂塗佈於接著性較差之熱塑性樹脂基材之情形時,為了提高與塗料之密接性,亦可進行底塗處理。
