Description
本发明涉及汽车制造工业中用作外涂层粉末涂料的粘结剂组合物。
外涂层或装饰涂层是涂覆系统的最后一层，它通常施于底漆、底涂层或表面上。
按汽车制造业现有技术的介绍，作为两组分体系使用的光亮外层涂料是用异氰酸酯固化的基于丙烯酸酯树脂的含溶剂的涂料体系。为了满足减少溶剂排放的要求，高固体含量的体系已经被使用。减少溶剂排放的唯一途径仍然是使用粉末涂料作为汽车的光亮涂料（Lattke E."Pulverlack am Aceto aus der Sicht der Autoindustrie"，刊登在″Der Pulvertreff 92，23.01.92，München″）。
对所述用途的粉末涂料体系来说，与含溶剂的体系有着同样的要求。这些要求与例如流动性、抗化学品性、光泽和户外耐久性有关（Kinza，W.″Pulverklarlack fur die Karosseriebes-chichtung，″刊登在″Die EPS-Praxis 1991，25.11.91，91，Bad Neuheim"）。目标是在低于150℃的固化温度下获得这些特性。在现有粉末树脂体系中，还没有发现能满足所有这些要求特性的体系。基于酸-环氧固化反应的体系能部分满足一些特性，但是，这些粉末涂料至今还远远不能获得好的流动性、好的抗化学品性、高光泽、高抗划伤、好的机械性能和好的户外耐久性等综合的优良特性。基于含羟基的聚合物和含保护的异氰酸酯基的固化剂的体系也能获得若干上述特性。这些体系的固化温度通常都高于170℃，该固化温度对于汽车（光亮）外涂层来说是太高了。
本发明的目的是提供一种粘结剂组合物，它能在较低的温度下固化，并且能给出全部的所需特性。能在汽车外表面形成光亮外涂层的粉末涂料。
本发明的粘结剂组合物包括羟值为20-100（mg KOH/g树脂）、酸值小于10（mg KOH/g树脂）的含羟基的聚酯或羟值为40-150（mg KOH/g树脂）、酸值小于20（mg KOH/g树脂）有含羟基的聚丙烯酸酯和保护的六亚甲基二异氰酸酯三聚物。
本发明粘结剂组合物在130℃-160℃固化得到的粉末涂料具有最佳流动性、抗汽油性、柔韧性和透明度。
按照本发明优选实施例，异氰酸酯三聚物用1，2，4-三唑保护。
含羟基的聚合物与含保护的异氰酸酯基团的粘结剂的重量比通常在90∶10到50∶50的范围内。
粘结剂组合物还可包括羟基官能的聚酯和羟基官能的聚丙烯酸酯的混合物。
在约100℃的温度下，通过例如挤塑的方法将羟基官能的聚合物与保护的交联剂共混，静电喷涂后，它们可以在130℃-170℃之间的温度下固化。
必要时可以添加常用添加到例如填料、流动助剂和/或稳定剂以及颜料，优选的是在挤塑过程中添加。
影响粉末涂料性能的参数和粉末涂料的生产技术见174-300页，Powder Coatings，Chemistry and Technology by Tosko Misev（John Wiley and sons;1991）。
通过常用的制备方法，由主要为芳香族的多元羧酸可以制得适宜的聚酯。适宜的酸包括邻苯二甲酸、间苯二甲酸、对苯二甲酸、1，2，4，5-苯四酸、1，2，4-苯三酸、3，6-二氯邻苯二甲酸、四氯邻苯二甲酸，及其酸酐、酰氯或低级烷基酯（如果可得到的话）。羧酸组分通常至少含50%（重量）、优选的至少含70%（摩尔）的间苯二甲酸和/或对苯二甲酸。
此外，尤其是脂肪族二醇例如乙二醇、丙-1，2-二醇、丙-1，3-二醇、丁-1，2-二醇、丁-1，4-二醇、丁-1，3-二醇、2，2-二甲基丙二醇-1，3（二新戊二醇）、己-2，5-二醇、己-1，6-二醇、2，2-[二（2-羟基乙氧基）]苯基丙烷和少量的多元醇例如甘油、己三醇、季戊四醇、山梨醇、三羟甲基乙烷、三羟甲基丙烷和三（2-羟基）异脲酸酯可以被采用。也可以用环氧化合物来代替二醇或多元醇。优选的醇组分至少含50%（摩尔）新戊二醇。
新戊二醇和/或三羟甲基丙烷是优选的多元醇，因为这些多元醇能够给出很好的户外耐久性。
适宜的多元酸包括环脂族和/或无环多元羧酸，例如环己烷二羧酸、四氢邻苯二甲酸、六氢桥亚甲基四氢邻苯二甲酸、壬二酸、癸二酸、癸烷二羧酸、脂肪酸二聚物、己二酸、丁二酸和马来酸。通常它们的用量至多为羧酸总量的30%（摩尔），优选的至多为20%（摩尔）。羟基羧酸和/或内酯也可以使用，例如12-羟基硬脂酸、ε-己内酯和羟基新戊酸与新戊二醇形成的酯。在制备过程中还可以加入少量的一元羧酸如苯甲酸、叔丁基苯甲酸、六氢苯甲酸和饱和的脂族一元羧酸。
聚酯可以通过本身已知的方法通过酯化作用或酯交换作用制备，制备过程中可以存在常用的催化剂如氧化二丁基锡或肽酸叔丁酯。选择适宜的制备条件和适宜的COOH/OH比，使得树脂的羟值为20-100（mg KOH/g树脂）、酸值小于10（mg KOH/树脂）。
按照本发明更优选的实施例，聚酯基于40-100%（摩尔）间苯二甲酸和0-60%对苯二甲酸为二元羧酸（间苯二甲酸和对苯二甲酸合起来为100%（摩尔））。更优选的为间苯二甲酸的量高于60%（摩尔）。
聚酯也可以基于两种以上的二元羧酸。
官能度大于或等于3的单体的用量优选低于其它单体的12%。数均分子量（Mn）优选的为1500-5000。分子量和支链组分的量合起来要保证聚酯的官能度为2.0-4.0较好。
羟基官能的丙烯酸酯树脂通常基于（甲基）丙烯酸羟乙酯、（甲基）丙烯酸羟丙酯和（甲基）丙烯酸甲酯。树脂也可以基于（甲基）丙烯酸和（甲基）丙烯酸烷基酯例如（甲基）丙烯酸乙酯、（甲基）丙烯酸异丙酯、（甲基）丙烯酸正丁酯、（甲基）丙烯酸正丙酯、（甲基）丙烯酸异丁酯、乙基己基丙烯酸酯和/或（甲基）丙烯酸环己酯和乙烯基化合物如苯乙烯。
按照本发明优选实施例，羟基官能的丙烯酸酯树脂基于：
a）10-35%（重量）甲基丙烯酸羟乙酯
b）2-25%（重量）丙烯酸正丁酯，和
c）50-70%（重量）甲基丙烯酸甲酯。
其中a+b+c＝100%（重量）。
羟基官能的丙烯酸酯树脂可以通过聚合来制备：第一步，将溶剂如甲苯、二甲苯或乙酸丁酯加入反应器中。然后加热至溶剂沸腾，随后用例如2-4小时的时间加入单体、引发剂和硫醇（可加可不加）然后在回流温度下保持例如2小时。用升高温度随后真空蒸馏例如1-2小时的方法蒸去溶剂。然后将产物沥干、冷却。
欧洲专利申请EP-A-4571介绍了基于羟基官能聚合物的粉末、溶剂型漆中使用1，2，4-三唑保护的异氰酸酯。但是，EP-A-4571并没有指出用本发明特点的粘结剂组合物能够解决汽车制造业中的所述问题。
美国专利申请US-A-4748242公开了含异氰脲酸酯基的多异氰酸酯的制备方法：将含与脂族伯碳原子相连的空间未受阻异氰酸酯基和与叔碳原子（该碳原子成为脂族环体系的一部分）相连的空间受阻异氰酸酯基的脂族-环脂族二异氰酸酯和1，6-二异氰酸根合己烷的混合物进行三聚作用。该专利还给出了按该方法生产的含异氰脲酸酯基的多异氰酸酯及其用途，用于聚氨酯漆较好，它可以取保护的形式，因为异氰酸酯成分在多异氰酸酯生产过程中形成加聚产物。适宜的保护剂包括1，2，4-三唑。为了生产漆粘结剂，可以将保护的异氰酸酯（不是必须的）、多官能反应组分、催化剂和其它常用添加剂如颜料（不是必须的）相互混合，用常用混合装置均化，可以添加溶剂和稀释剂，也可以不加，然后用常用方法，以溶液或熔融、或固态形式将其施于待涂物体上。US-A-4748242并没有指出用该方法制备可用作汽车外壳光亮涂层的粉末涂料。
本发明粉末涂料也可以用于木制品或用作一般用途的工业外涂层，机器设备的外涂层，特别是金属如罐、家用物品和其它小件设备的外层涂料。
