Description

用于注塑组合物的粘合剂
本发明涉及用于注塑的粘合剂组合物以及用于生产成型金属或陶瓷部件的注塑组合物(进料)。
粉末冶金技术用于生产在珠宝制造和钟表制造工业中所用的硬材料，或用于技术应用例如医疗、电子、电话或工具工业，机械切割插件，消费物品工业，以及尤其用于通常称为无机“陶瓷”的硬材料。所得的无机合成材料将在这里称为“陶瓷”，与此材料的性质无关，其是蓝宝石、红宝石、人造钻石、蓝宝石玻璃、陶瓷、微磁体、金属、合金等。
一般而言，基本原料在性质上是不同的，并且在一方面至少包含陶瓷粉末，另一方面包含有机粘合剂，例如树脂或塑性材料等，它们可以注塑并提供用所有原料的混合物制备的组件的优良牢固性。在此混合物中也可以包含其它添加剂。这些原料也可以具有不同的纹理：固体，粉末，液体或糊料。当树脂的补充组分发生聚合反应时，混合物的结构也可以尤其在其形成期间变化，但不限于此。
用于生产无机陶瓷部件的全部工序包括至少以下步骤：
-制备原料；
-混合这些原料，或/和在需要时将两种(或更多种)原料预先混合；
-均匀混合；
-造粒；
-从混合和造粒得到的一定量的粉末或进料颗粒进行压制或模塑，尤其是在模塑室中，形成“粗制”部件。这种模塑可以通过在压力下注射进行，尤其是在螺杆挤出机中，其包括用于将从混合和造粒得到的一定量的粉末或进料颗粒进行加热的装置；
-在烘箱中脱粘以使混合物的特定组分燃烧或溶解；
-将“粗制”部件在脱粘之后进行热处理，进行烧结工艺，以得到具有最终内聚力的部件。这种热处理引起尺寸收缩，这使得可以获得具有最终尺寸的部件。
-对部件进行表面整理处理。
本发明的一个具体目的是提供优化的用于注塑组合物的粘合剂，其能促进粉末冶金混合以获得陶瓷或金属材料，从而获得具有高度可重现性品质以及可控收缩系数的产品。
例如从美国专利No.5145900已经知道用于制备含有可烧结无机粉末和聚合物有机粘合剂的模塑陶瓷部件的热塑性材料(进料)，其是基本上由聚甲醛以及聚甲醛和聚四氢呋喃共聚物的混合物组成。
但是，发现这些进料具有许多缺点，例如对于注塑的流动性不足，以及关于产品保持其模塑形状以免裂纹或分层的问题。这对于具有复杂形状的部件的情况尤其如此。它们也由于必须使用攻击性产品例如硝酸而导致环境问题，尤其是最后除去有机相时。此外，在有机粘合剂除去工艺中使用水在含有金属材料的进料的情况下也存在氧化的风险。
所以，本发明的一个目的是提供一种用于模塑组合物的粘合剂，其能克服上述缺点，更尤其改进进料的均匀性和流动性，从而允许生产具有更复杂形状的金属或陶瓷部件，减少生产循环时间，提高“粗制”脱粘体的抗应力性能以(处理和各种机械操作)，和最后避免使用对环境有害的产品以除去有机粘合剂，这通过用没有污染性的溶剂代替所述产品实现，所述溶剂能通过简单热处理除去。
所以，本发明涉及用于注塑组合物的粘合剂，其含有：
-35-54体积％的聚合物基料，
-40-55体积％的蜡混合物或蜡和棕榈油的混合物，
-和约10体积％的表面活性剂，
其中聚合物基料含有乙烯和甲基丙烯酸或丙烯酸的共聚物，或含马来酸酐的乙烯共聚物，或这些共聚物的混合物，以及聚乙烯、聚丙烯和丙烯酸树脂，所述粘合剂组分的各用量使得它们的总和不超过100％。
优选，本发明的粘合剂包含2-7体积％的一种所述共聚物或其混合物、约25体积％的聚乙烯、2-15体积％的聚丙烯以及6-15体积％的丙烯酸树脂。
根据本发明的一个方案，用于注塑组合物的粘合剂含有：
-35-54体积％的聚合物基料，
-40-55体积％的蜡混合物或蜡和棕榈油的混合物，
-和约10体积％的表面活性剂，
其中聚合物基料含有2-7体积％的乙烯-乙酸乙烯酯共聚物、约25体积％的聚乙烯、2-15体积％的聚丙烯以及6-15体积％的丙烯酸树脂，所述粘合剂组分的各用量使得它们的总和不超过100％。
应当注意的是，所选择的乙烯-乙酸乙烯酯共聚物在上述范围(2-7体积％)内的用量对于形成足够硬以尤其在注塑后从模具取出时保持其形状的“粗制”部件(在脱粘和烧结之前的注塑部件)而言是重要的；这种特征在部件截面越小的情况下就越重要。通常，约15％的这些聚合物不会向小截面的粗制部件提供从模具取出时的足够的刚度。
根据一种优选方法，乙烯和甲基丙烯酸或丙烯酸的共聚物含有3-10重量％的甲基丙烯酸或丙烯酸型共聚单体，乙烯和乙酸乙烯酯的共聚物含有7-18重量％的乙酸乙烯酯共聚单体，并且乙烯和酸酐的共聚物是熔点为100-110℃的乙烯和马来酸酐的无规共聚物，或者熔点为130-134℃的HD聚乙烯和改性酸酐的共聚物。
优选，丙烯酸树脂具有50000-220000的分子量，且特性粘数为0.21-0.83，并且选自甲基丙烯酸异丁酯、甲基丙烯酸甲酯、甲基丙烯酸乙酯和甲基丙烯酸正丁酯的聚合物，甲基丙烯酸异丁酯和甲基丙烯酸正丁基酯的共聚物，以及甲基丙烯酸甲酯和甲基丙烯酸正丁基酯的共聚物，或者这些聚合物和/或共聚物的混合物。“特性粘数”表示在50ml二氯甲烷中含有0.25g聚合物的溶液在20℃下用Cannon-Fenske粘度计检测的粘度。
有利的是，蜡是巴西棕榈蜡或石蜡，或棕榈油，或这些物质的混合物，通常是巴西棕榈蜡和石蜡的混合物，或巴西棕榈蜡和棕榈油的混合物。根据另一个优选特征，表面活性剂是N,N’-亚乙基二硬脂酰胺，或者硬脂酸和棕榈酸的混合物(硬脂精)，或这些物质的混合物。
根据另一个特征，表面活性剂和丙烯酸树脂能溶于异丙醇和/或松节油中。
本发明还涉及一种用于生产成型金属或陶瓷部件的注塑组合物(进料)，其含有76-96重量％的无机粉末和4-24重量％的包含以下组分的粘合剂：
-35-54体积％的聚合物基料，
-40-55体积％的蜡混合物，
-和约10体积％的表面活性剂，
其中聚合物基料含有乙烯和甲基丙烯酸或丙烯酸的共聚物，或含马来酸酐的乙烯共聚物，或这些共聚物的混合物，以及聚乙烯、聚丙烯和丙烯酸树脂。
根据一个具体特征，所述注塑组合物中的无机粉末可以选自氧化物、氮化物、碳化物、金属粉末，或这些粉末的混合物，优选无机粉末选自氧化铝粉末、氧化锆粉末、碳化铬粉末、碳化钛粉末或碳化钨粉末，钨金属或氮化硅粉末，不锈钢粉末，钛金属粉末，或这些粉末的混合物。
根据注塑组合物的优选实施方案，所述组合物含有按重量百分比计的以下组分：
●76-88％的氧化铝，和12-24％的如上所述的本发明粘合剂，或
●76-88％的氧化铝和0.1-0.6％的氧化镁，以及12-24％的本发明粘合剂，或
●58-86.5％的氧化锆和3.9-4.6％的氧化钇和0.18-18.5％的氧化铝和9-22％的本发明粘合剂，或
●61.5-84％的氧化锆和3.9-4.6％的氧化钇和0.2-9％的氧化铝和2-5.5％的无机颜料以及9-22％本发明粘合剂，其中无机颜料选自氧化铁、氧化钴、氧化铬、氧化钛、氧化锰、氧化锌或所述氧化物的混合物，或
●88-91％的碳化铬或碳化钛，以及9-12％的本发明粘合剂，或
●93-96％的碳化钨或钨金属，以及4-7％的本发明粘合剂，或
●78-85％的氮化硅，以及15-22％的本发明粘合剂。
下面将通过以下非限制性实施例更详细地描述本发明。
实施例1
粘合剂的聚合物部件与黑色氧化锆粉末(例如St.GobainZirBlack)在约150℃下混合以形成预混物。向所述预混物加入蜡和表面活性剂，并使得温度进一步升高到约180℃以形成一种均匀糊料，然后将其冷却并造粒直到固化，然后保持以形成进料，所述进料可以用于通过按照公知技术注塑生产成型部件。
此技术通常包括在具有空隙的模具中使用加热进行高压注塑操作。将此部件在空隙中冷却然后从模具取出。整个过程在约180℃下进行。然后将“粗制”部件脱粘并然后烧结。脱粘操作从部件除去了部分有机粘合剂以留下仅仅足以保持粘结的粘合剂，或换句话说保持“粗制”部件的模塑形状。通常通过加热浸泡部件的溶剂而从“粗制”部件除去粘合剂。在此操作中，至少40％的粘合剂化合物必须溶解。关于本发明的粘合剂，“粗制”部件通常被浸入溶剂中并加热到约70℃的温度。在此温度下，蜡混合物或蜡和油的混合物发生热分解，同时表面活性剂和丙烯酸树脂被化学溶解。一旦完成脱粘操作，部件就成为多孔的。然后将此部件放入高温烘箱中，从而在第一个阶段中除去剩余的粘合剂(通常在低于400℃的温度下)，此操作是通过在脱粘期间留在部件中的孔隙率促进的，然后在第二个阶段中将部件在高温下烧结。
在此实施例中，更具体而言，使用17.2kg的锆粉末(86重量％)和2.8kg的具有以下体积组成的粘合剂(约14重量％)：
-24％的HD聚乙烯
-10％的聚丙烯
-4％的乙烯和甲基丙烯酸的共聚物(含有6.5重量％的甲基丙烯酸，例如来自DuPont的"Nucrel(TM)")
-10％的甲基丙烯酸异丁基酯聚合物树脂，其具有195,000的分子量(例如来自LuciteInternational的'Elvacite(TM)2045')
-1％的甲基丙烯酸正丁基和异丁基酯聚合物树脂，其具有195,000的分子量(例如来自LuciteInternational的'Elvacite(TM)2046')
-11％的巴西棕榈蜡
-31％的石蜡(例如来自AlphaWaxBV的'Carisma54T(TM)')
-6％的N,N'-亚乙基-二(硬脂酰胺)
-3％的硬脂酸棕榈酸混合物(例如来自Dubois的Stearin(硬脂精))。
实施例2
用白色氧化锆代替黑色氧化锆制备与上述实施例1相同类型的进料，并且其中使用稍微不同用量的各种粘合剂组分，具体而言：
-26％的HD聚乙烯
-10％的聚丙烯
-4％的乙烯和甲基丙烯酸的共聚物
-11％的'Elvacite2045'树脂
-1％的'Elvacite2046'树脂
-11％的巴西棕榈蜡
-29％的石蜡
-8％的N,N'-亚乙基-二(硬脂酰胺)。
实施例3
再次使用相同的有机粘合剂组分，但是使用稍微不同的体积比例，可以用各种陶瓷或金属粉末制备其它进料，更尤其使用氧化铝，其收缩指数为1.19或1.30(半透明)，或使用碳化铬或碳化钛、碳化钨(不同用量)和钨金属，如下表所示：
