Description
本發明關於一種能夠賦予聚烯烴系樹脂優異的防霧性,而不會對聚烯烴系樹脂膜的透明性及製膜穩定性有不好的影響的聚烯烴系樹脂膜用改質劑、含有該改質劑的聚烯烴系樹脂膜用組成物、使用該樹脂膜用組成物而成形的改質聚烯烴系樹脂膜、及具有該改質聚烯烴系樹脂膜作為至少一側的表層的積層膜。
聚烯烴系樹脂組成物成形而成的膜通常被廣泛地使用作為例如包裝資材等。由於聚烯烴系樹脂原本就具有疏水性的性質,故從防止因靜電所引起的帶電、起霧等觀點而言,有時會使用包含界面活性劑等的聚烯烴系樹脂用改質劑。
目前已知有例如專利文獻1~3所揭示的聚烯烴系樹脂用改質劑。專利文獻1揭示一種關於含有聚甘油脂肪酸酯等的構成。專利文獻2揭示一種關於含有甘油與碳數8~22的脂肪酸所構成的單酯、二甘油與碳數8~22的脂肪酸所構成的單酯、聚氧乙烯烷基胺基醚、聚氧乙烯烷基胺基醚與碳數8~22的脂肪酸所構成的單酯或單、雙酯的混合物等的構成。專利文獻3揭示一種關於含有甘油與脂肪酸所構成的酯化物、聚甘油與脂肪酸所構成的酯化物、二甘油與脂肪酸所構成的酯化物等的構成。

上述3~6價的多元醇與碳數8~22的直鏈脂肪族羧酸所構成的部分酯能夠以公知的方法製造。製造方法並無特別限定,能夠列舉例如在油脂與3~6價的多元醇的混合物中不添加觸媒或者添加鹼作為觸媒,並於氮或二氧化碳等任意的惰性氣體氛圍下加熱進行酯交換反應的方法。加熱條件中,溫度範圍較佳為約180~260℃、更佳為約200~250℃,處理時間較佳為約0.5~5小時、更佳為約1~3小時。其中,此處所用的鹼性觸媒能夠列舉例如氫氧化鉀、氫氧化鈉、碳酸鉀、碳酸鈉等。或者,也能夠列舉在碳數8~22的直鏈脂肪族羧酸與3~6價的多元醇的混合物中不添加觸媒或者添加酸或鹼作為觸媒,並於氮或二氧化碳等任意的惰性氣體氛圍下加熱進行酯化反應,反應結束後再中和觸媒的方法等。加熱條件中,由於溫度範圍較佳為約180~260℃、更佳為約200~250℃,故處理時間較佳為約0.5~5小時、更佳為約1~3小時。此外,也能夠在酯化反應後將未反應的3~6價的多元醇進行去除、脫色及脫臭等處理。
從上述反應物中將未反應的3~6價的多元醇去除或將特定的酯化合物回收的方法能夠適用公知的方法,可列舉例如減壓蒸餾、分子蒸餾、管柱色層分析、液液萃取等。上述3~6價的多元醇與碳數8~22的直鏈脂肪族羧酸之單酯/雙酯比率的調整能夠藉由調整上述反應條件而直接使用所獲得的化合物,也能夠將上述方法所回收的特定的酯化合物進行秤量並混合。上述酯化合物中所含的單酯及雙酯的含量能夠藉由凝膠浸透色層分析來測定。
提供作為本實施方式的改質劑的部分酯,能夠較佳使用浸透量為20mg/g以上者。浸透量是一種改質劑對於聚烯烴樹脂的浸漬量,能夠根據JIS K 7114「求出對塑料-液體藥品的浸漬效果的試驗方法」而算出。浸透量測定時使用的聚烯烴樹脂能夠列舉乙烯-(1-丁烯)共聚物(密度:0.920g/cm3
、MFR:2.1g/10分鐘、乙烯共聚合比率95%)等。其中,JIS K 7114對應1999年發行的第2版ISO175,Plastics−Methods of test for the determination of the effects of immersion in liquid chemicals,兩者的技術内容相同。
上述3~6價的多元醇與碳數8~22的直鏈脂肪族羧酸所構成的部分酯的浸透量較佳為20mg/g以上。當浸透量為20mg/g以上時,能夠提高改質劑對於聚烯烴系樹脂的溶解度,並能夠進一步提升聚烯烴系樹脂膜的製膜穩定性。
提供作為本實施方式的改質劑的部分酯,能夠較佳使用親油性親水性平衡值(HLB:Hydrophile-Lipophile Balance)為2~8.5者,更佳為5~8.5者。若HLB位於上述範圍,則能夠獲得製膜穩定性及防霧性更優異的聚烯烴系樹脂膜。特別是當HLB為2以上時,由於改質劑的親水性高,故能夠進一步提升防霧性。此外,特別是當HLB為8.5以下時,能夠提高與疏水性之聚烯烴系樹脂的相溶性,並進一步提升聚烯烴系樹脂膜的製膜穩定性。
HLB値是一種表示界面活性劑對於水與油的親和性的程度的値,本發明採用由下述公式計算的ATLAS法的數值。
[計算式]
HLB=20×(1-S/A)
S:酯的皂化價
A:酯的中和價
本實施方式的改質劑所適用的聚烯烴系樹脂的具體例能夠列舉例如(1)使用乙烯、丙烯、1-丁烯、1-己烯、4-甲基戊烯-1、1-辛烯等選自碳數2~8的α-烯烴中之一種而獲得的聚乙烯、聚丙烯等α-烯烴單獨聚合物、(2)使用選自如上述碳數2~8的α-烯烴中之二種以上而獲得的乙烯・丙烯共聚物、乙烯・1-丁烯共聚物、乙烯・1-己烯共聚物等α-烯烴共聚物、(3)由乙烯與醋酸乙烯所獲得的共聚物、(4)由乙烯與醋酸乙烯所獲得的共聚物經皂化而得的乙烯・乙烯醇共聚物、(5)使用乙烯與選自丙烯酸、丙烯酸甲酯、及丙烯酸乙酯中之一種或二種以上所獲得的乙烯・丙烯酸共聚物、(6)使用乙烯與選自甲基丙烯酸及甲基丙烯酸甲酯中之一種或二種以上所獲得的乙烯・甲基丙烯酸共聚物等。該等之中又以上述(2)的α-烯烴共聚物之乙烯與碳數4~8的α-烯烴所構成的共聚物較佳。此外,又以含有由該碳數4~8的α-烯烴所構成的單位1~50質量%者更佳。該α-烯烴共聚物進而又以皆使用公知的高活性戚格勒觸媒、茂金屬觸媒等均一系觸媒,並藉由氣相法、溶液聚合法等而獲得者更佳。此外,又以密度為0.86~0.95g/cm3
、MFR為0.01~30g/10分鐘者特佳。以上例示的烯烴系樹脂能夠單獨使用,也能夠混合使用二種以上的烯烴系樹脂。
本實施方式的改質劑適用的聚烯烴系樹脂膜中,具有碳數8~22的烷基或烯基的二乙醇胺化合物或具有碳數8~22的烷基或烯基的二乙醇醯胺化合物的含量為0.02質量%以下,較佳為0.01質量%以下。更佳為:適用的聚烯烴系樹脂膜實質上不包含上述二乙醇胺化合物或上述二乙醇醯胺化合物。所謂「實質上不包含上述二乙醇胺化合物或上述二乙醇醯胺化合物」的意思是指「不額外含有上述二乙醇胺化合物或上述二乙醇醯胺化合物」,並未排除各原料中的雜質等所含的少量的上述二乙醇胺化合物或上述二乙醇醯胺化合物。當聚烯烴系樹脂膜中上述二乙醇胺化合物或上述二乙醇醯胺化合物為0.01質量%以下時,能夠提升膜的透明性。
此外,本實施方式的改質劑適用的聚烯烴系樹脂膜中,烷基磺酸鹼金屬鹽的含量為0.004質量%以下,較佳為0.001質量%以下。更佳為:適用的聚烯烴系樹脂膜實質上不包含烷基磺酸鹼金屬鹽。所謂「實質上不包含烷基磺酸鹼金屬鹽」的意思是指「不額外含有烷基磺酸鹼金屬鹽」,並未排除各原料中的雜質等所含的少量的烷基磺酸鹼金屬鹽。當聚烯烴系樹脂膜中烷基磺酸鹼金屬鹽為0.004質量%以下時,能夠提升膜的製膜穩定性。
其中,當改質劑適用於多層膜時,膜中上述二乙醇胺化合物或上述二乙醇醯胺化合物的含量及烷基磺酸鹼金屬鹽的含量表示配合有改質劑的層中的含量。
適用有本實施方式的改質劑的聚烯烴系樹脂膜的用途並無特別限定。適用有本實施方式的改質劑的聚烯烴系樹脂膜由於透明性及防霧性優異故可較佳適用於食品用膜。
(第2實施方式)
