Description

一种聚酯合成复合催化剂的制备方法 技术领域
本发明属于聚酯合成催化剂的技术领域, 特别是涉及一种可用作聚酯和 共聚酯酯化及缩聚反应的钛 /硅 /锡复合催化剂。 背景技术
聚酯是由二元醇和二元酸缩聚而得的聚合物的总称, 是一类性能优异、 用途广泛的工程塑料, 在薄膜、 瓶用包装、 片材等领域有重要用途。
聚酯催化剂的研究自聚酯问世以来从未停止过, 目前应用于工业生产和 研究较多的主要有锑、 锗和钛三个系列的催化剂, 其中最常用的是锑系催化 剂 (包括 Sb203、 SbAc3和乙二醇锑等)。 当今世界上 90%的聚酯是由锑系催 化剂生产出来的。 锑系催化剂活性适中, 副反应少, 但是在聚酯合成过程中 会还原析出, 使聚酯切片成灰色, 增加纺丝组件的压力, 另外它是重金属催 化剂, 会对环境造成污染, 不符合可持续发展要求。 锗系催化剂稳定性好, 所合成的聚酯产品色相佳, 但是锗金属价格昂贵, 应用有极大的局限性。 钛 系催化剂活性高, 不含重金属, 是目前研究最多的一类催化剂, 早期使用的 是钛的无机盐或者有机酯类, 制得的聚酯产品存在稳定性差和制品泛黄、 浑 浊, 应用受到了限制。
在 Acordis公司申请的专利 W095191164.3中提到了出牌号为 C-94的无 毒高效催化剂, 主要组分为 Ti02/Si02和 Ti02/Zr02, 适合生产 PET、 PBT和 PTT等; Zimmer公司开发出牌号为 EcocatB和 Ecocat T两种催化剂, 在缩聚 反应中, 具有催化活性的金属化合物吸附在非均相的载体上; ICI公司下属的 Synetix公司推出过以钛为基础的聚酯催化剂, 牌号分别为 AC400、 AC300、 AC200和 AC240等; CN1138339公开了釆用钛酸酯和硅酸酯供水解制得的钛 系聚酯催化剂, CN1259969公开了钛酸酯与金属化合物共沉淀制得的钛系聚 酯催化剂。
上述专利公开的催化剂制得的聚酯色相仍然不是艮好 , 色相值与釆用锑 系催化剂相比扔然较高, 没有解决钛系催化剂制得的聚酯发黄的问题。 目前 尚无制得的钛系催化剂对酯化及缩聚都有不错的催化作用, 且所得产品的色 相很好。 发明内容
本发明的目的是提供一种用于聚酯合成复合催化剂的制备方法, 制得的 固体催化剂不仅对聚酯缩聚反应有效果, 且对酯化作用也有艮好的作用, 所 得聚酯切片色相也较好。
为达到上述目的, 本发明的方法包括如下步骤:
1)将钛化合物、 硅化合物和锡化合物溶解于有机溶剂, 在搅拌下加入酸 性化合物或碱性化合物的水溶液, 水解反应 0.5〜lh, 水解反应温度为
15〜30。C;
2)水解结束后, 收集水解沉淀物, 然后用去离子水洗涤所述水解沉淀物, 即得所述复合催化剂;
所述钛化合物的结构通式为 TiOR1^其中 R1为具有 2〜 4个碳原子的烷 基;
所述硅化合物的结构通式为 Si(OR2)4,其中 R2为具有 2〜4个碳原子的烷 基;
所述锡化合物为四氯化锡(SnCl4);
所述硅化合物和钛化合物的摩尔比为: 0.05-0.5: 1;

所述有机溶剂与钛化合物、 硅化合物和锡化合物总摩尔量的摩尔比为: 10~40: 1。
进一步, 所述有机溶剂与钛化合物、 硅化合物和锡化合物总摩尔量的摩 尔比优选为 15-20: L
进一步, 所述钛化合物选自钛酸四乙酯、 钛酸四丙酯、 钛酸四异丙酯或 钛酸四丁酯。 进一步, 所述硅化合物选自正硅酸乙酯或正硅酸丁酯。
进一步, 所述钛化合物和硅化合物的摩尔比为 0.06 ~ 0.1 : 1 , 所述锡化 合物和钛化合物的摩尔比为 0.5 ~ 1 : 1。
进一步, 所述有机溶剂选自曱醇、 乙醇、 异丙醇、 异丁醇、 正己醇、 乙 二醇、 丁二醇、 己二醇或丙三醇。
进一步, 所述有机溶剂为乙醇。
水解过程中, 通过加入适量的酸性化合物或者碱性化合物来调控金属盐 类的水解速度, 具体量化到其水溶液的 PH值, 所述酸性化合物包括各种无机 酸或有机酸, 优选的无机酸为磷酸、 盐酸或石危酸, 优选的有机酸为醋酸。 所 述碱性化合物选自氨水、 氢氧化钠或氢氧化钾。

本发明所述聚酯合成是两步法即经过酯化与缩聚两步反应完成聚酯的合 成, 具体是指第一步由二元羧酸和二元醇进行酯化反应, 得到预聚物, 酯化 反应温度为 200〜240。C, 在常压下反应, 第二步在真空条件下进行缩聚反应, 反应温度为 240 ~ 260°C, 压力为 60 ~ 130 Pa, 以二元酸和二元醇总重量为基 准, 催化剂的用量为 200 - 250 ppm。
与现有技术相比, 本发明的创新点在于: 本发明在钛和硅的混合物中加 入了锡化合物进行共水解, 所得的催化不仅对聚酯缩聚过程有效, 对酯化过 程同样有效果, 且所得聚酯具有良好的色相, 取得了良好的技术效果。 具体实施方式
