Description
技术领域
本发明涉及一种不饱和聚酯树脂组合物及其模制品，特别是涉及一种低苯乙烯挥发的不饱和聚酯树脂组合物及其模制品。
背景技术
不饱和聚酯树脂由二元醇与二元酸在介于190至220℃进行酯化反应，达到预期的酸值(或黏度)后，再以一定量的苯乙烯单体稀释溶解成黏稠状液体，即为不饱和聚酯树脂。不饱和聚酯树脂硬化、成形可在常温常压下进行，不饱和聚酯树脂的硬化产物具有良好的机械强度及电气性质，且有优异的抗酸腐蚀、耐候性以及耐水性，且可以省去加热装置，据此，不饱和聚酯树脂广泛应用于注型、片状模塑料(SMC)或块状模塑料(BMC)制造工艺，各项塑料行业产品。
不饱和聚酯树脂的树脂分子链中含双键，可与含双键的单体发生共聚反应，形成三维立体结构，故具有优良的机械性能和耐化学腐蚀等性能。一般而言，现有技术是以苯乙烯作为不饱和聚酯树脂稀释剂和共聚单体，且其用量占树脂总量高达30至40％。然而，因苯乙烯沸点不高、容易挥发，在室温下蒸气压高，且具有特殊气味和毒性，对现场操作人员的健康和环境负荷带来极大的危害，因此，开发低含量苯乙烯的不饱和聚酯树脂已成为该项事业所欲解决的重要课题之一。
发明内容
本发明所要解决的技术问题在于，针对现有技术的不足提供一种低苯乙烯挥发不饱和聚酯树脂组合物。
为了解决上述的技术问题，本发明所采用的其中一技术方案是提供一种低苯乙烯挥发不饱和聚酯树脂组合物，其包括：30至60重量份的不饱和聚酯树脂以及2至30重量份的共聚单体。其中，共聚单体包括：(a)甲基苯乙烯；(b)羟基丙烯酸酯单体；以及(c)苯二甲酸二烯丙酯单体，且所述共聚单体中，(a)、(b)、(c)含量的重量比例为6:3:1。
更进一步地，所述不饱和聚酯树脂组合物的苯乙烯含量低于5wt％。
更进一步地，所述不饱和聚酯树脂是选自邻苯二甲酸型不饱和聚酯、间苯二甲酸型不饱和聚酯以及对苯二甲酸型不饱和聚酯所组成的群组。

更进一步地，所述苯二甲酸二烯丙酯单体是选自邻苯二甲酸二烯丙酯和间苯二甲酸二烯丙酯所组成的群组。
更进一步地，所述共聚单体基于所述不饱和聚酯树脂以及所述共聚单体的重量百分比总合是介于2至50wt％。
为了解决上述的技术问题，本发明所采用的另一技术方案是提供一种模制品，其是将本发明的不饱和聚酯树脂组合物加热固化而成。
本发明的其中一有益效果在于，本发明所提供的不饱和聚酯树脂组合物及其模制品，其能通过“所述共聚单体包括：(a)甲基苯乙烯；(b)羟基丙烯酸酯单体；以及(c)苯二甲酸二烯丙酯单体”以及“所述共聚单体中，(a)、(b)、(c)含量的重量比例为6:3:1”的技术方案，以得到一低苯乙烯挥发的不饱和聚酯树脂组合物。
为使能更进一步了解本发明的特征及技术内容，请参阅以下有关本发明的详细说明，然而所提供的内容仅用于提供参考与说明，并非用来对本发明加以限制。
具体实施方式
以下是通过特定的具体实施例来说明本发明所公开有关“不饱和聚酯树脂组合物及其模制品”的实施方式，本领域技术人员可由本说明书所公开的内容了解本发明的优点与效果。本发明可通过其他不同的具体实施例加以施行或应用，本说明书中的各项细节也可基于不同观点与应用，在不背离本发明的构思下进行各种修改与变更。以下的实施方式将进一步详细说明本发明的相关技术内容，但所公开的内容并非用以限制本发明的保护范围。另外，本文中所使用的术语“或”，应视实际情况可能包括相关联的列出项目中的任一个或者多个的组合。冠词“一”在本文中用于表示一个或多于一个(即至少一个)该冠词的语法对象。例如，“一环氧基”是指一个环氧基或多于一个环氧基。
本发明提供一种低苯乙烯挥发不饱和聚酯树脂组合物，其包括：30至60重量份的不饱和聚酯树脂以及2至30重量份的共聚单体。其中，共聚单体包括：(a)甲基苯乙烯；(b)羟基丙烯酸酯单体；以及(c)苯二甲酸二烯丙酯单体，且所述共聚单体中(a)、(b)、(c)含量的重量比例为6:3:1。
较佳地，不饱和聚酯树脂与共聚单体的重量比例为4：1至7：1。
更详细来说，不饱和聚酯树脂是选自邻苯二甲酸型不饱和聚酯、间苯二甲酸型不饱和聚酯以及对苯二甲酸型不饱和聚酯所组成的群组。较佳地，不饱和聚酯树脂的聚合度为2至8，在25℃下黏度为5000至30000cps。
更详细来说，羟基丙烯酸酯单体选自丙烯酸羟乙酯、甲基丙烯酸羟乙酯、丙烯酸羟丙酯、甲基丙烯酸羟丙酯以及季戊四醇三丙烯酸酯所组成的群组。
更详细来说，羟基丙烯酸酯单体选自丙烯酸羟乙酯、甲基丙烯酸羟乙酯、丙烯酸羟丙酯、甲基丙烯酸羟丙酯以及季戊四醇三丙烯酸酯所组成的群组。
更详细来说，苯二甲酸二烯丙酯单体是选自邻苯二甲酸二烯丙酯和间苯二甲酸二烯丙酯所组成的群组。
较佳地，所述共聚单体基于所述不饱和聚酯树脂以及所述共聚单体的重量百分比总合是介于5至20wt％。具体来说，本发明使用的共聚单体沸点较高，室温蒸气压低，不易挥发，挥发性有机物(VOC)少，可改善生产条件，保护操作人员的健康并减少环境污染。
除此之外，现有技术的不饱和聚酯树脂固化时体积收缩率大，进而影响制品尺寸和表面光泽度，通过本发明选用的共聚单体，可有效改善此一问题且又不影响其他物性。

本发明的不饱和聚酯树脂组合物合成的各种条件需根据所使用的原料或其量适当地设定，但一般而言，在氮气等不活性气体气流中，以140至230℃之温度于加压或减压下酯化。该酯化反应中，可视需求使用酯化触媒。作为触媒的例，可列举：乙酸锰、二丁基氧化锡、草酸亚锡、乙酸锌、及乙酸钴等公知的触媒。该等可单独或组合多个使用。
本发明另提供一种模制品，其是将本发明的不饱和聚酯树脂组合物加热固化而成。换句话说，本发明的不饱和聚酯树脂组合物可通过由习知的混合及浸渍法，依照前述配比组成制备成SMC(片状模制化合物)、TMC(厚型模制化合物)或BMC(整体模制化合物)。
根据本发明的不饱和聚酯树脂组合物的模制品可在预定温度和预定压力下，于压模机或注模机中，将不饱和聚酯树脂组合物加热及模压予以制备。例如，于1至12MPa的压力及80至160℃的温度下，将不饱和聚酯树脂组合物固化。

更进一步来说，本发明所使用的共聚单体沸点较高，室温蒸气压低、不易挥发，挥发性有机物(VOC)少，可改善生产条件，保护操作人员的健康和减少环境污染。
除此之外，现有技术的不饱和聚酯树脂固化时体积收缩率大，进而影响制品尺寸和表面光泽度，通过本发明选用的共聚单体，可有效改善此一问题，提供低收缩率的不饱和聚酯树脂组合物。
以上所公开的内容仅为本发明的优选可行实施例，并非因此局限本发明的权利要求书的保护范围，所以凡是运用本发明说明书内容所做的等效技术变化，均包含于本发明的权利要求书的保护范围内。
