Abstract
本發明提供一種聚異氰酸酯組合物等,該聚異氰酸酯組合物係由選自由脂肪族二異氰酸酯及脂環族二異氰酸酯所組成之群中之至少1種二異氰酸酯、及選自由數量平均分子量Mn為500以上之二官能聚酯多元醇(A)及數量平均分子量Mn為500以上之三官能以上之聚酯多元醇(B)所組成之群中之至少1種聚酯多元醇衍生,上述二異氰酸酯之異氰酸基相對於上述聚酯多元醇之羥基之莫耳比為1.5以上30.0以下,上述聚異氰酸酯組合物之重量平均分子量為1400以上800000以下。The present invention provides a polyisocyanate composition, etc. The polyisocyanate composition is derived from at least one diisocyanate selected from the group consisting of aliphatic diisocyanates and alicyclic diisocyanates, and at least one polyester polyol selected from the group consisting of a difunctional polyester polyol (A) having a number average molecular weight Mn of 500 or more and a trifunctional or higher polyester polyol (B) having a number average molecular weight Mn of 500 or more, wherein the molar ratio of the isocyanate group of the diisocyanate to the hydroxyl group of the polyester polyol is 1.5 to 30.0, and the weight average molecular weight of the polyisocyanate composition is 1400 to 800000.
Description
本發明係關於一種聚異氰酸酯組合物、硬化膜、黏著性樹脂組合物、黏著性樹脂片材、及積層膜。 The present invention relates to a polyisocyanate composition, a hardened film, an adhesive resin composition, an adhesive resin sheet, and a laminate film.
近年來,塑膠膜或黏接著劑由於具有廣泛之功能,故而於各種領域中使用。於此種情況下,不僅向平坦部位之應用增加,向曲面部或具有彎折運動之部位之類的此前較少之用途之應用亦增加。例如,可例舉比如軟性顯示器或可摺疊顯示器、汽車之構件等之貼合,近年來需求迅速擴大。隨之,針對曲面或彎曲,要求追隨性、伸縮性及耐彎曲性良好且強韌之高柔軟性膜或黏接著劑。又,對於光學用途,同時亦要求較高之透明性,具體為霧度值為3.0%以下。 In recent years, plastic films or adhesives have been used in various fields due to their wide range of functions. In this case, applications have increased not only to flat parts, but also to curved parts or parts with bending movements, which were previously less common. For example, the bonding of flexible displays or foldable displays, automotive components, etc. has seen a rapid increase in demand in recent years. As a result, for curved surfaces or bends, highly flexible films or adhesives with good tracking, stretchability, and bending resistance and strong toughness are required. In addition, for optical uses, higher transparency is also required, specifically a haze value of 3.0% or less.
例如,專利文獻1中揭示一種具有伸展性之聚胺基甲酸酯塗料用預聚物之製造方法,該方法包括使脂肪族二異氰酸酯或脂環族二異氰酸酯與數量平均分子量為500以上1500以下之聚己內酯二醇及/或三醇發生反應。又,專利文獻2中揭示一種混合物,該混合物係使脂肪族二異氰酸酯或脂環族二異氰酸酯與數量平均分子量為700以上1500以下之聚四亞甲基二醇 發生反應所得之預聚物、與使脂肪族二異氰酸酯或脂環族二異氰酸酯與數量平均分子量為500以上1500以下之聚己內酯多元醇發生反應所得之預聚物的混合物。 For example, Patent Document 1 discloses a method for producing a prepolymer for polyurethane coating having stretchability, which method comprises reacting an aliphatic diisocyanate or alicyclic diisocyanate with a polycaprolactone diol and/or triol having a number average molecular weight of 500 to 1500. In addition, Patent Document 2 discloses a mixture, which is a mixture of a prepolymer obtained by reacting an aliphatic diisocyanate or alicyclic diisocyanate with a polytetramethylene glycol having a number average molecular weight of 700 to 1500, and a prepolymer obtained by reacting an aliphatic diisocyanate or alicyclic diisocyanate with a polycaprolactone polyol having a number average molecular weight of 500 to 1500.

[專利文獻2]日本專利特開平02-001718號公報 [Patent document 2] Japanese Patent Publication No. 02-001718
然而,專利文獻1或專利文獻2等中記載之先前之藉由聚酯多元醇或聚醚多元醇改性之聚異氰酸酯之柔軟性有改良之餘地。又,於該等文獻中,研究僅限於塗料用途,未對於黏接著劑中之應用進行具體研究,進而,完全未著眼於聚異氰酸酯之結構與透明性之相關性。 However, the softness of the polyisocyanate modified by polyester polyol or polyether polyol described in Patent Document 1 or Patent Document 2 etc. has room for improvement. Moreover, in these documents, the research is limited to the use in coatings, and no specific research is conducted on the application in adhesives. Furthermore, no attention is paid to the correlation between the structure and transparency of polyisocyanate.
本發明係鑒於上述情況而成,提供一種聚異氰酸酯組合物,其能夠獲得使聚異氰酸酯組合物單獨硬化而成之硬化膜之柔軟性及透明性良好且伸長率及拉伸斷裂應力優異之硬化膜、以及黏著力、硬化性及透明性優異之黏著性樹脂組合物及黏著性樹脂片材。又,本發明提供一種具備上述黏著性樹脂片材之積層膜。 The present invention is made in view of the above situation, and provides a polyisocyanate composition, which can obtain a cured film formed by curing the polyisocyanate composition alone, which has good flexibility and transparency, and excellent elongation and tensile fracture stress, as well as an adhesive resin composition and an adhesive resin sheet with excellent adhesion, curability and transparency.

聚異氰酸酯係使上述二異氰酸酯、與選自由聚酯多元醇(A)及聚酯多 元醇(B)所組成之群中之1種以上聚酯多元醇發生反應而得。以下有時將聚酯多元醇(A)及聚酯多元醇(B)合併僅稱為聚酯多元醇。 The polyisocyanate is obtained by reacting the above-mentioned diisocyanate with one or more polyester polyols selected from the group consisting of polyester polyols (A) and polyester polyols (B). In the following, polyester polyols (A) and polyester polyols (B) may be collectively referred to as polyester polyols.
於將聚酯多元醇(A)及聚酯多元醇(B)組合使用之情形時,聚酯多元醇(A)及聚酯多元醇(B)可分別單獨使用,或以混合物之形態使用。於以混合物之形態使用之情形時,可於與二異氰酸酯反應前混合,亦可於使各聚酯多元醇單獨與二異氰酸酯反應而製成聚異氰酸酯後混合。 When polyester polyol (A) and polyester polyol (B) are used in combination, polyester polyol (A) and polyester polyol (B) may be used separately or in the form of a mixture. When used in the form of a mixture, they may be mixed before reacting with diisocyanate, or after reacting each polyester polyol with diisocyanate to prepare polyisocyanate.
即,作為聚異氰酸酯組合物之製造方法,例如可例舉以下方法等:使二異氰酸酯、聚酯多元醇(A)及聚酯多元醇(B)同時反應,獲得聚異氰酸酯組合物;將使二異氰酸酯與聚酯多元醇(A)反應所得者、與使二異氰酸酯與聚酯多元醇(B)反應所得者加以混合,獲得聚異氰酸酯組合物;使二異氰酸酯與聚酯多元醇(A)或聚酯多元醇(B)反應後,使殘留之聚酯多元醇進一步反應,獲得聚異氰酸酯組合物。 That is, as a method for producing a polyisocyanate composition, for example, the following methods can be cited: reacting diisocyanate, polyester polyol (A) and polyester polyol (B) simultaneously to obtain a polyisocyanate composition; mixing the product obtained by reacting diisocyanate with polyester polyol (A) and the product obtained by reacting diisocyanate with polyester polyol (B) to obtain a polyisocyanate composition; reacting diisocyanate with polyester polyol (A) or polyester polyol (B), and then further reacting the remaining polyester polyol to obtain a polyisocyanate composition.

聚酯多元醇與二異氰酸酯之反應係以如下方式進行。反應溫度通常為室溫(23℃左右)以上200℃以下,較佳為60℃以上180℃以下,較佳為60℃以上170℃以下。若反應溫度為上述下限值以上,則反應時間變得更 短,另一方面,若反應溫度為上述上限值以下,則能夠進一步避免不希望之由副反應所導致之聚異氰酸酯之黏度上升及凝膠化,亦能夠進一步避免生成之聚異氰酸酯之著色。 The reaction of polyester polyol and diisocyanate is carried out as follows. The reaction temperature is usually above room temperature (about 23°C) and below 200°C, preferably above 60°C and below 180°C, and preferably above 60°C and below 170°C. If the reaction temperature is above the lower limit, the reaction time becomes shorter. On the other hand, if the reaction temperature is below the upper limit, the undesirable viscosity increase and gelation of the polyisocyanate caused by the side reaction can be further avoided, and the coloring of the generated polyisocyanate can also be further avoided.
反應可於無溶劑之狀態下進行,亦可使用對異氰酸基惰性之任意溶劑進行。又,為了促進異氰酸基與羥基之反應,可視需要使用公知之觸媒。 The reaction can be carried out in the absence of a solvent, or using any solvent inert to isocyanate groups. In addition, in order to promote the reaction between isocyanate groups and hydroxyl groups, a known catalyst can be used as needed.

By making the glass transition temperature Tg of the polymer containing a crosslinking functional group within the above range, the adhesive resin composition tends to have a better adhesion. The glass transition temperature of a polymer containing a crosslinking functional group can be, for example, the following value, which is obtained by dispersing an organic solvent and water in a solution containing a polymer containing a crosslinking functional group under reduced pressure and then vacuum drying the solution, using a differential scanning calorimetry (DSC) measuring device at a temperature increase rate of 5°C/min.
