Description
技术领域
本发明涉及液晶聚合物技术领域,尤其是一种液晶聚酯、液晶聚酯组合物及应用。
背景技术
液晶聚酯(LCP)作为一种高性能的特种工程塑料,广泛应用于电子电器及小型精密薄壁零部件等领域。随着电子电器制件向薄轻小方面发展,集成电路的密集化,特别是表面安装技术的应用,对液晶聚酯材料的耐热性能提出了更高的要求,液晶聚酯材料需具备不低于260℃的耐焊料温度。
为了改善液晶聚酯耐热性,本领域专业人员做了较多尝试。CN 108026258 A提供了一种包含特定的结构单元、各结构单元的含量为特定的范围、酮键的量为特定的范围的全芳香族聚酯,该全芳香族聚酯为液晶性聚合物,充分兼顾低熔点化与耐热性、且色调优异,其热变形温度处于245-260℃范围。CN 108026269 A公开了一种包含特定的结构单元、各结构单元的含量为特定的范围、酮键的量为特定的范围的全芳香族聚酯酰胺,该全芳香族聚酯酰胺为液晶性聚合物,充分兼顾低熔点化与耐热性,具备245-270℃的热变形温度。CN 109561791 A通过在液晶聚酯树脂中添加滑石等填料,制备得到的耐热器皿的热变形温度可达270℃以上。
到目前为止,通过提供高熔融焓液晶聚酯配方及方法,以实现液晶聚酯及组合物高耐热性的手段,未出现报道。
发明内容
基于此,本发明的目的在于克服上述现有技术局限,而提供了新技术方案,通过提供一种液晶聚酯、液晶聚酯组合物及应用,以改善液晶聚酯和液晶组合物的耐热性能。
为实现上述目的,本发明所采取的技术方案为:
一种液晶聚酯,所述液晶聚酯包括下述式(1)重复单元、式(2)重复单元和式(3)重复单元:
(1)-O-Ar1-CO-
(2)-CO-Ar2-CO-
(3)-O-Ar3-O-
其中,Ar1为2,6-亚萘基、1,4-亚苯基和4,4'-亚联苯基中的至少一种;Ar2为1,4-亚苯基、1,3-亚苯基或4,4'-亚联苯基;Ar3为2,6-亚萘基、1,4-亚苯基、1,3-亚苯基或4,4'-亚联苯基;
所述液晶聚酯的熔融焓>1.5J/g,熔融焓采用DSC测得第二次熔融曲线,计算出熔融峰面积即为熔融焓。
熔融焓通常用于表征塑料制品熔融过程所需能量。液晶聚酯聚合物分子链排列的有序性、晶格堆砌紧密程度、分子链段及晶体运动的难易程度均可通过熔融焓反映。发明人研究发现,液晶聚酯包括上述特定的重复单元,且当液晶聚酯的熔融焓>1.5J/g时,液晶聚酯的热变形温度>290℃,体现出优异的热变形温度及抗起泡性能。
进一步地,所述液晶聚酯按摩尔百分比计,包含如下重复单元:
(A)Ar1为2,6-亚萘基的式(1)重复单元45~65mol%;
(B)Ar1为1,4-亚苯基的式(1)重复单元1~6mol%;
(C)Ar2为1,4-亚苯基的式(2)重复单元15~26mol%;
(D)Ar3为4,4'-亚联苯基的式(3)重复单元15~26mol%。
更进一步地,所述液晶聚酯按摩尔百分比计,包含如下重复单元:
(A)Ar1为2,6-亚萘基的式(1)重复单元45~60mol%;
(B)Ar1为1,4-亚苯基的式(1)重复单元1~5mol%;
(C)Ar2为1,4-亚苯基的式(2)重复单元19~26mol%;
(D)Ar3为4,4'-亚联苯基的式(3)重复单元19~26mol%。
在上述范围内,制备得到的液晶聚酯具有高耐热性、同时兼顾良好抗起泡性能、低介电损耗,适用于高频率通信电子部件。
本发明还提供了上述的液晶聚酯的制备方法,所述制备方法包括以下步骤:
S1.式(1)重复单元的单体、式(3)重复单元的单体与酰化剂在离子液体的催化作用下进行酰化反应;
S2.步骤S1的酰化产物与式(2)重复单元的单体在离子液体的催化作用下进行熔融缩聚和减压缩聚,得到预聚物,其中,在熔融缩聚阶段,在280-300℃保持恒温15min以上,从生产效率及能耗角度,更优选15-30min;
S3.预聚物排出、冷却固化并造粒,进行固相聚合,得到所述液晶聚酯;
其中,所述离子液体为含有两个或两个以上氮原子的杂环有机碱类化合物与阴离子功能化合物反应成的离子液体。
本发明在液晶聚酯反应前期引入离子液体作为高效催化剂,离子液体由于阴阳离子之间有较强的库伦力,稳定性优良,催化效果持久;离子液体催化剂具有高效定向催化性,催化效果明显,在反应中体现出高酰化效率,且分子链支化交联等副反应减少,有利于形成分子链段规整的聚合物结构,从而易于结晶生长及形成晶区,形成较高熔融焓的液晶聚合物。
另外,在熔融缩聚阶段,在280~300℃保持恒温15min以上,优选15~30min,可促进式(2)重复单元的单体充分聚合,减少式(2)重复单元的单体损失,从而提高液晶聚酯分子链段的规整程度,更易于形成晶体结构,从而使液晶聚酯表现出高熔融焓的特性。
进一步地,所述离子液体的添加量为液晶聚酯的理论出料重量的500ppm以上,从经济性角度优选为500~3000ppm,在此范围内,酰化率高,更有利于提高液晶聚酯的熔融焓、热变形温度和抗起泡性能。
本发明中“液晶聚酯的理论出料重量”是指式(1)重复单元的单体、式(2)重复单元的单体、式(3)重复单元的单体与酰化剂在离子液体的作用下,经酰化反应、熔融缩聚、减压缩聚和固相聚合阶段所合成的液晶聚酯的理论产量。
进一步地,所述含有两个或两个以上氮原子的杂环有机碱类化合物为咪唑化合物、三唑化合物或二吡啶基化合物,所述咪唑化合物为1-甲基咪唑、2-甲基咪唑、4-甲基咪唑、1-乙基咪唑、2-乙基咪唑、4-乙基咪唑、1,2-二甲基咪唑、1,4-二甲基咪唑或2,4-二甲基咪唑,优选为1-甲基咪唑;所述三唑化合物包括但不限于1,2,4-三唑、1,2,3-三唑和苯并三唑中的至少一种;所述二吡啶基化合物包括但不限于2,2’-二吡啶基和4,4’-二吡啶基中的至少一种。
进一步地,所述的阴离子功能化合物为乙酸、丙酸或丁酸,优选为乙酸。
更进一步地,所述离子液体为咪唑乙酸盐,所述咪唑乙酸盐的制备方法为:咪唑化合物与乙酸在80℃搅拌反应24小时。所述咪唑化合物优选为1-甲基咪唑,反应制备得到1-甲基咪唑乙酸盐离子液体。
进一步地,式(1)重复单元的单体如式(1’)所示、式(2)重复单元的单体如式(2’)所示、式(3)重复单元的单体如式(3’)所示;
(1’)G1-O-Ar1-CO-G2,
(2’)G2-CO-Ar2-CO-G2,
(3’)G1-O-Ar3-O-G1
其中,Ar1为2,6-亚萘基、1,4-亚苯基和4,4'-亚联苯基中的至少一种;Ar2为1,4-亚苯基、1,3-亚苯基或4,4'-亚联苯基;Ar3为2,6-亚萘基、1,4-亚苯基、1,3-亚苯基或4,4'-亚联苯基;3个G1各自独立地表示氢原子或烷基羰基;3个G2各自独立地表示羟基、烷氧基、芳氧基、烷基羰基氧基或卤原子。
进一步地,式(1)重复单元的单体优选为4-羟基苯甲酸、6-羟基-2-萘甲酸中的至少一种;
式(2)重复单元的单体优选为对苯二甲酸、间苯二甲酸、4,4'-联苯二甲酸的至少一种,进一步优选对苯二甲酸;
式(3)重复单元的单体优选为对苯二酚、4,4'-二羟基联苯中的至少一种。
进一步地,酰化剂中能够酰化羟基的官能团与式(1)重复单元的单体和式(3)重复单元中总羟基量的摩尔比为1.01:1~1.10:1,酰化反应温度控制为120~150℃,确保酰化反应充分进行,提高酰化率。
本发明可选用常规的酰化剂,比如醋酸酐、丙酸酐、丁酸酐、戊酸酐等。
进一步地,在步骤S2的熔融缩聚阶段,以0.3~1.5℃/min的升温速率升温至280~300℃,在280~300℃保持恒温15~30min,最后继续采用0.3~1.5℃/min的升温速率升温至目标产品熔点10℃以下,且熔点30℃以上([Tm-10]~[Tm+30]℃),升温期间不断馏出醋酸及其副产物。

具体实施方式
为更好的说明本发明的目的、技术方案和优点,下面将结合具体实施例对本发明作进一步说明。
对以下实施例和对比例的原料做如下说明:
HNA:6-羟基-2-萘甲酸,Sigma-Aldrich公司;
BP:4,4'-二羟基联苯,Sigma-Aldrich公司;
TA:对苯二甲酸,Sigma-Aldrich公司;
HBA:4-羟基苯甲酸,Sigma-Aldrich公司;
IA:间苯二甲酸,Sigma-Aldrich公司;
APAP:乙酰氨基酚,Sigma-Aldrich公司
醋酸镁:Sigma-Aldrich公司;
玻璃纤维、滑石粉、云母粉和钛白粉均来自市售;1-甲基咪唑乙酸盐离子液体为自制,其具体制备方法如下:1-甲基咪唑与乙酸在80℃搅拌反应24小时得到1-甲基咪唑乙酸盐离子液体。
对本发明的熔融温度、熔融焓、熔融粘度、热变形温度和抗起泡性的测定方法做如下说明:
(1)熔融温度:采用NETZSCH公司DSC 200F3测得,从室温起以20℃/min的升温速率升温到熔点+(20~80)℃的最高温度,在此温度下停留2min后再以20℃/min的速率降温至室温,测试样品在室温下停留2min后再次以20℃/min的升温速率升温到熔点+(20~80)℃的最高温度,得到聚合物的第二次熔融曲线,选取熔融峰值即为熔点。
(2)熔融焓:采用(1)中的第二次熔融曲线,并选取熔融峰的熔融起始温度和熔融结束温度,并计算出熔融峰面积即为熔融焓。
(3)熔融粘度:采用Dynisco LCR7000型毛细管流变仪测试,测试温度在液晶聚酯熔融温度以上30℃,剪切速率1000s-1,使用内径1mm、长度40mm的口模测量。
(4)热变形温度:将测试样品注塑成型为80mm×10mm×4mm的试样,使用该试样按照ISO 75-2 2013标准在1.82MPa载荷下以2℃/min的加热速率测量热变形温度。
(5)抗起泡性:在液晶聚酯熔融温度以上5℃以及60mm/s的注射速度下,将液晶聚酯或其组合物成型为厚度1.0mm,长宽为60mm的薄片状试样。将这些试样中的10个试样放入260℃的烘箱中5min,然后将试样取出,观察各试样表面的气泡产生情况。抗起泡性采用起泡率进行衡量,起泡率=起泡块数/总块数*100%,起泡率越低,抗起泡性越好。
实施例1-8和对比例1-8:液晶聚酯
实施例1-8和对比例1-8的液晶聚酯的原料成分如表1所示,液晶聚酯的制备方法包括以下步骤:
S1.乙酰化工段:在装有搅拌器、单体投料口、回流冷凝器、温度计和氮气导入口的第一反应容器中,加入单体、醋酸酐和催化剂,投料完成后,用氮气彻底置换反应容器内的气氛,在氮气保护下将反应体系的温度升高至140℃,维持此温度回流2小时进行乙酰化反应;
S2.熔融缩聚工段:乙酰化反应结束后,把物料转入配有扭矩传感器的搅拌器、保护气导入口、采出装置和真空装置的第二反应容器中,搅拌并以1℃/min的升温速率升温至280~300℃,并在280~300℃恒温一定时间,然后再以1℃/min的升温速率升温至360℃,在此过程中,通过醋酸采出装置将聚合生成的醋酸采出;
S3.减压缩聚工段:待物料温度达到360℃后,在30min内将第二反应容器中的压力降低至10kPa;
S4.待扭矩达到设定值后,通过保护气导入口通入氮气,使第二反应容器的压力至0.3MPa,此时将预聚物经第二反应容器的排出口以熔融态排出,冷却固化后造粒,投入转鼓进行固相聚合增粘,增粘温度290℃,真空度至100Pa以下,达到既定熔融粘度降温,得到液晶聚酯。
实施例1-8和对比例1-8的液晶聚酯的原料成分、合成工艺参数、熔融粘度、熔点、熔融焓、HDT和起泡率如表1所示。
表1
由表1中,比较上述实施例1-3、实施例6-7和对比例4-8的结果发现,本发明通过优选聚合单体的种类及其用量,有利于提高液晶聚酯熔融焓,从而提高热变形温度,并降低起泡率,这也是本申请中具体进一步限定“所述液晶聚酯按摩尔百分比计,包含如下重复单元:(A)Ar1为2,6-亚萘基的式(1)重复单元45~65mol%;(B)Ar1为1,4-亚苯基的式(1)重复单元1~6mol%;(C)Ar2为1,4-亚苯基的式(2)重复单元15~26mol%;(D)Ar3为4,4'-亚联苯基的式(3)重复单元15~26mol%”的原因。
实施例2、实施例4、实施例8和对比例3结果可知,液晶聚酯在熔融缩聚过程中,采用280~300℃恒温15~30min,有利于提高液晶聚酯的熔融焓,从而提高热变形温度,并降低起泡率。
实施例2、实施例5和对比例1-2的结果可知,相较于对比例1采用醋酸镁作为催化剂,本发明选用1-甲基咪唑乙酸盐离子液体作为催化剂,乙酰化率高,更有利于获得熔融焓高、热变形温度高、起泡率低的液晶聚酯。当1-甲基咪唑乙酸盐离子液体的添加量为液晶聚酯的理论出料重量的500ppm以上效果较好。
实施例1’-11’和对比例1’-3’:液晶聚酯组合物
按表2配比分别将实施例1-4和对比例1的液晶聚酯,以及增强填料用高速混合机混合均匀后,加入双螺杆挤出机,通过熔融混合,挤出造粒,冷却,得到液晶聚酯组合物。
实施例1’-11’和对比例1’-3’得到的液晶聚酯组合物的原料成分、熔融焓、HDT、起泡率和拉伸强度如表2所示。
表2
由实施例1’、实施例3’-4’、对比例1’结果可知,在液晶聚酯用量、增强填料种类及其用量相同情况下,液晶聚酯熔融焓越高,其液晶聚酯组合物熔融焓随之提高,且具有高热变形温度、低起泡率。
由实施例5’、对比例2’-3’结果可知,在液晶聚酯的熔融焓相同的情况下,液晶聚酯及增强填料用量处于一定比例,制备得到的液晶聚酯组合物可兼顾良好的耐热性、抗起泡性、力学性能,因此,本申请中具体进一步限定“所述液晶聚酯组合物按重量份计,包括液晶聚酯50~80份和增强填料20~50份”。
由实施例2’、实施例6’、实施例9’-实施例10’结果可知,玻璃纤维的平均长度在一定范围内时,制备得到的液晶聚酯组合物可兼顾良好的热变形温度和力学拉伸性能。
由实施例6’-8’、实施例11’结果可知,滑石粉、云母粉、钛白粉等非纤维状增强填料的平均粒径过大,会导致制备得到的液晶聚酯组合物抗起泡性变差。
最后所应当说明的是,以上实施例仅用以说明本发明的技术方案而非对本发明保护范围的限制,尽管参照较佳实施例对本发明作了详细说明,本领域的普通技术人员应当理解,可以对本发明的技术方案进行修改或者等同替换,而不脱离本发明技术方案的实质和范围。
