Abstract
本發明所欲解決之課題係使用生物質原料,提供與布料(尤其撥水性布料)之接著性優良的濕氣硬化型聚胺基甲酸酯樹脂組成物。
本發明係提供一種濕氣硬化型聚胺基甲酸酯熱熔(hot-melt)樹脂組成物,其特徵為含有具有異氰酸基之胺基甲酸酯預聚物(i),該預聚物(i)為多元醇(A)及多元異氰酸酯(B)之反應產物,該多元醇(A)包含以源自生物質之多元酸(x)及源自生物質之二醇(y)作為原料的聚酯多元醇(a1)。又,本發明提供一種接著劑,其特徵為含有前述濕氣硬化型聚胺基甲酸酯熱熔樹脂組成物。
Description
本發明係關於濕氣硬化型聚胺基甲酸酯樹脂組成物、接著劑、及積層體。
兼具透濕性及防水性之透濕防水機能性衣料,係以接著劑使透濕性薄膜貼合在布料而成的構成體,就前述接著劑而言,從與透濕性薄膜及布料雙方之密著性良好的觀點而言,一般使用胺基甲酸酯系接著劑。又,在前述胺基甲酸酯系接著劑中,因最近世界之溶劑排放規定或殘留溶劑規定,而無溶劑型之濕氣硬化型聚胺基甲酸酯樹脂組成物的使用量正慢慢地增加中(例如,參照專利文獻1)。
另一方面,所使用之布料,係因高機能化而細丹尼(denier)化及撥水度提高,亦被指摘有因此而與接著劑之接著性變差的課題,而當今之濕氣硬化型聚胺基甲酸酯樹脂組成物中,目前並未發現有對超撥水布料表現特別高密著性者。
再者,如同最近之海洋塑膠問題受到矚目般,對於以擺脫石化資源為目標之生物系(bio-based)樹脂的矚目度亦日益上升,濕氣硬化型聚胺基甲酸酯樹脂組成物也不例外。

[與布料之接著性的評價方法]
將實施例及比較例中所得到之濕氣硬化型聚胺基甲酸酯熱熔樹脂組成物於100℃熔融後,使用凹輪塗布機(40L/inch,130深度,附著量:10g/m2
),塗覆於透濕薄膜(Kahei Co., Ltd.製「VENTEX」),且分別與以下3種布料貼合,於溫度23℃、濕度50%之環境下放置2日,而得到加工布。
布料(1):非撥水布料(表面自由能:超過50mJ/m2
者)
布料(2);撥水布料(表面自由能:於10~50mJ/m2
之範圍者)
布料(3);超撥水布料(表面自由能:低於10mJ/m2
者)
將所得到之加工布裁切成1吋寬,使用島津製作所(Shimadzu Corporation)製「Autograph AG-1」,測定透濕薄膜與布料之剝離強度(N/inch)。
