Description

在反應性稀釋劑中脂肪族二醯胺添加劑之經預濃縮及預活化組成物
發明領域
本發明係關於一種新穎特定的流變添加劑,其係一種已經預活化之脂肪酸二醯胺基礎組成物,特別是,其係呈凝膠或糊膏形式,其脂肪酸二醯胺係經預濃縮及其包含一以12-羥基硬脂酸(12-HSA)與線性脂肪族二胺為主之微粒化的脂肪酸二醯胺及一單官能基(甲基)丙烯酸反應性稀釋劑。本發明亦關於一種製備方法;關於一種包括該特定添加劑的反應性黏著劑組成物;及關於其用途,其係使用在該反應性黏著劑的反應性組成物中用於立即使用且不需要再活化該脂肪族二醯胺添加劑。因此,此特定添加劑的用途特別針對該反應性黏著劑之反應性組成物,例如塗佈組成物,諸如塗料、清漆、凝膠塗層或油墨;或膠泥、黏膠、黏著或模塑組成物;複合材料組成物、化學錨栓組成物、密封膠組成物;或特別是,藉由噴墨用於立體微影法或用於物件的3D列印之可光交聯組成物。
發明背景
諸如脂肪酸二醯胺的流變添加劑之活化在于當該二醯胺以微粒化粉末形式均勻分散在合適於該二醯胺及最後用途或應用的稀釋劑或塑化劑中後,於與該二醯胺及稀釋劑相依而提供的溫度下,將該分散物維持在等溫條件下一段足夠時間,直到其黏度及安定度增加並獲得一物理凝膠。
從而活化的凝膠(亦稱為經活化的糊膏)所具有之特徵首先為若所測試的產物經充分活化且該流變凝膠或糊膏保持單相時,可使用木製抹刀進行相當簡單的測試,將其引進欲測試的凝膠或糊膏及其將保持垂直不移動;及絕不滲出該反應性稀釋劑。
更特別的是,該經活化的凝膠或糊膏所具有之特徵為穿透深度,其可根據標準ASTM D 217使用穿透計或藉由測量所獲得的凝膠之動態彈性模數獲得。就穿透來說,根據標準ASTM D 217,該經活化的凝膠之典型值係少於15毫米,或在23℃及1赫茲下之動態彈性模數E’係至少104巴斯卡。
在諸如二甲苯的惰性溶劑中,選擇性在含有醇的溶劑混合物中或在醋酸乙烯酯中或在白油溶劑中預活化之流變添加劑的商業糊膏已經出現。但是,這些惰性溶劑易燃,其會以蒸氣(已知為VOCs的揮發性有機化合物)排放進環境中。除了排放這些易燃的VOC之效應外,在反應性黏著劑的反應性組成物中使用此預活化的添加劑之額外效應將由於所獲得的最後物件或塗佈物之塑化效應而在 最後機械性能程度上具有負面效應。
EP 1 935 934描述出在液體塑化劑中之經預活化及預濃縮的脂肪酸二醯胺添加劑組成物。此系統具有與上述已經提及之相同考慮到塑化在使用以反應性黏著劑為主的反應性組成物所獲得之塗佈物或物體中其機械性能程度上具負面效應的缺點。再者,該塑化劑與該反應性黏著劑組成物的反應性組分在相容性上會有問題。因為該塑化劑具惰性且不與該反應性系統相容,其具有至少部分會漂移至所獲得的塗佈物或物件表面之趨勢,此會在所獲得的最後物體或塗佈物表面處產生黏附問題。
以單組分或二組分反應性黏著劑為主之反應性組成物將遭遇到的額外問題為事實上必需避免在該脂肪酸二醯胺添加劑之活化期間,於聚合及特別是交聯反應前,在該二醯胺之活化期間,該反應性組分於最後調配物中過早就地反應的風險。
發明概要
為了克服全部這些缺點,本發明建議使用呈預活化組成物形式的流變添加劑,其脂肪酸二醯胺經預濃縮且使用參與該反應性組成物之反應的反應性稀釋劑作為稀釋劑,該稀釋劑係一單官能基(甲基)丙烯酸酯單體。結果,該稀釋劑將化學整合進最後產物中而不塑化最後產物,也不會漂移至所獲得的最後物件或塗佈物表面,此雖然使用低量之預濃縮及已經預活化的添加劑,但對在包括該反應性黏 著劑的反應性組分之反應性組成物中的添加劑之活化並無任何需求,因此避免該最後反應性組成物之任何過早聚合,特別是交聯的風險。因此,該反應性黏著劑或最後應用調配物的反應性組成物可藉由簡單稀釋該經預活化、預濃縮的添加劑而具有想要的觸變性程度,及可立即使用(接受反應)而不需要先前合適長的就地活化步驟,因此沒有任何過早反應的風險。
此溶液的另一個優點為使用此預活化及預濃縮添加劑,特別是呈預活化的凝膠或糊膏形式之可能性,二者在反應性系統中係藉由自由基途徑,不論是在輻射或熱下或藉由以過氧化物或氫過氧化物為主的起始系統或藉由Michael加成反應與反應性胺基組分進行反應,其中例如在環氧基胺二組分反應性黏著劑的情況中,該稀釋劑係單丙烯酸酯。
首先,本發明係關於在該反應性稀釋劑中之預活化及預濃縮的脂肪酸二醯胺組成物,此組成物可呈預活化的糊膏或凝膠形式。
另一個目標係關於一種用以製備該添加劑的方法。
本發明亦關於一種反應性黏著劑之反應性組成物或調配物,其包含該添加劑作為流變添加劑,特別是作為觸變性添加劑。
最後,本發明係關於如根據本發明所定義的添加劑之用途,其係使用作為用於反應性黏著劑組成物的 流變添加劑,用以立即使用而不需要就地額外活化該添加劑。
