Description

颜料混合物
技术领域
本发明涉及一种基于具有限定粒度分布的球形颗粒的颜料混合物，并涉及其在油漆、涂料、印刷油墨、安全印刷油墨、塑料、陶瓷材料、玻璃中，在化妆品配制剂中，作为示踪物，作为填料和用于制备颜料制剂和干制剂的用途。
背景技术
术语颜料适用于在应用介质中不溶的着色剂。有机颜料的典型实例是酞菁、二酮吡咯并吡咯、偶氮颜料和喹吖啶酮。无机颜料中可以提到各种类型的铁氧化物或者还有群青。颜料通常以较高的化学和光化学稳定性区别于可溶于应用介质的染料。
填料可以看作颜料的一种特殊形式。在填料的情况下，“着色”功能不是最优先。在工业填料的情况下，提高的机械稳定性、耐磨性、气候稳定性或者还有生产成本等因素反而对其应用是关键的。
填料也广泛用于化妆品配制剂。例如，粉末可以包括基于最终配制剂高达50％的填料。典型值是唇膏中10-15％的填料而乳液中2-6％的填料。化妆品填料履行完全不同的功能：在粉底中，由于所谓的消光效果它们防止了在皮肤上不期望的油腻光泽，而在散粉中它们帮助例如改进倾倒行为(pouring behavior)或对皮肤的施涂性质。在除臭产品中，利用有些填料的高液体吸收能力。
在用于待着色的体系之前，必须使化妆品中的填料或颜料成为有利于容易分散和可重现的色彩的形式。对最终产品的质量有重要影响的颜料的这些预处理例如粉碎，是费时和昂贵的。进一步不利的是当润湿时颜料的颜色变化。对于化妆品配制剂，颜料必须另外具有良好的皮肤触感，而传统的填料只很小程度上显示这样触感。
在化妆品中正越来越多采用基于球形颗粒的填料，特别是SiO2球，因为一方面它们赋予人体皮肤的自然外观，另一方面可以使皱纹不太明显。
覆盖有着色层的无机球形填料是已知的，例如从公布说明书JP62-288662、JP11-139926、JP11-335240和DE19929109已知。
WO 00/15720公开了具有高光漫射的基于球形SiO2球形颗粒的颜料混合物，其中一些SiO2球涂覆有TiO2和SiO2，而另一些涂覆有TiO2和Fe2O3。
WO 99/66883描述了涂覆有金属氧化物如氧化钛、铁氧化物或氧化锌的SiO2球，其具有最终的SiO2层。以这种方式涂覆的SiO2球用于化妆品配制剂中作为具有干涉颜料的混合物。
现有技术已知的基于SiO2球的填料显示相对好的皮肤触感，但缺点是它们具有过高的散射能力。其原因在于球形填料的金属氧化物层的结构。现有技术的功能性颜料一般由非常小的颗粒组成，即，它们具有0.5–100nm的粒径，其均匀布置地覆盖载体球体的表面。光在层表面反射，从而导致光泽。然而，同时会发生相当程度的散射，因为单个颗粒在层上形成并充当散射的强中心。这两个相对效果(光泽和散射)的结果是，颜料在皮肤上具有白色且不自然的外观。
因此，本发明的目的是提供一种功能性颜料，其除了良好的皮肤触感之外，同时在化妆品配制剂中具有良好的分散性、化学和光化学稳定性以及与皮肤匹配的纯色。此外，当作为纯散粉，在乳膏、乳剂、粉底等中施涂到皮肤时，颜料应表现出柔软、均匀、自然的皮肤外观。进一步期望颜料使坚实度，特别是液体和膏状制剂的坚实度略有增加，并保证制剂的稳定性。这使得在皮肤上分散化妆品制剂更格外容易了。因此，可以制备高粘度乳膏，即坚实的粉底，但是其在皮肤上具有非常好的分散能力或者具有非常好的从容器移除的移除行为。
除了这些产品性质之外，本发明的再一个目的是颜料的简单工业制备。也应该可以在制备方法过程中以简单的方式监测颜料的某些性能的设置，例如，遮盖力和具体可调的色强度。
令人惊讶地，已经发现，基于表面涂覆有TiO2+SiO2或者TiO2+铁氧化物且具有限定粒度分布的球形颗粒的颜料混合物，可以比现有技术的填料/颜料更好地调整遮盖力和具有显著更自然的皮肤外观，还具有更好的皮肤触感。此外，根据本发明的颜料混合物对质地和稳定性呈现出所需的影响，即，略微增加乳剂的粘度或粉底的坚实性而不对施涂性质产生不利影响，并且同时维持制剂的稳定性。
发明内容
因此，本发明涉及一种基于球形颗粒的颜料混合物，特征在于其包含至少两种组分A和B，其中
-组分A是基于未涂覆颗粒的粒度分布D90为0.5-15μm的球形颗粒，其中所述颗粒表面首先用TiO2涂覆并随后用SiO2涂覆，
和
-组分B是基于未涂覆颗粒的粒度分布D90为0.5-15μm的球形颗粒，其中所述颗粒表面首先用TiO2涂覆并随后用铁氧化物或者用TiO2和铁氧化物的混合物涂覆。
与现有技术的颜料相比，根据本发明的球形颜料表现出
-更自然的色彩匹配的皮肤外观
-更容易的分散性
-改进的可加工性
-可以在宽范围内进行调整的遮盖力
-改进的皮肤触感
-改进的化妆品制剂质地
-改进的化妆品配制剂的施涂行为。
本发明还涉及根据本发明的颜料混合物在油漆，涂料优选在工业涂料中、印刷油墨、安全印刷油墨、塑料、陶瓷材料、玻璃中，作为示踪物，作为填料和特别是在化妆品配制剂中的用途。此外，根据本发明的颜料也适用于制备颜料制剂和用于制备干制剂，如颗粒剂、珠粒剂、片剂(chip)、球剂、肠衣剂(sausage)、压块剂等。干制剂特别是用于印刷油墨和化妆品中。
适合的基础基材是球形颗粒，例如市售的，特别是来自SunjinChemicals、Kobo、Ikeda、Asahi Glass、Miyoshi、Omega Materials、3M、ABC NanoTech、China New Technology、PQ Corporation、Sibelco或者Evonik。优选的球形颗粒选自硅酸镁、硅酸铝、碱金属的硅铝酸盐、碱土金属的硅铝酸盐及其组合，SiO2球，玻璃珠，中空玻璃珠，氧化铝，和包含乙烯-丙烯酸共聚物、乙烯-甲基丙烯酸酯共聚物、HDI-三羟甲基己基内酯共聚物、尼龙、聚丙烯酸酯、聚甲基丙烯酸甲酯共聚物、聚乙烯、聚甲基硅倍半氧烷及其组合的聚合物珠。
特别优选的球形基材是SiO2球，例如以商品名SUNSIL、MSS-500、SHERON、SUNSPHERE、Silicabeads SB、OMEGA-SIL、OMEGA-Spheres、SPHERICEL、Q-Cel、Ceramic Microspheres、Glasbubbles iM-K、SILNOS、SS-T4、SORBOSIL、AEROSIL、Flo-Beads、BPD、Daiamid、MSP、TOSPEARL市售的。
通过氮气吸附测定的合适球形基础颗粒的BET表面积通常为1-1000，优选10-750，特别是20-550m2/g。在本专利申请中的BET表面积根据DIN ISO9277:2003-05测定。
根据本发明的颜料混合物的球形基础基材优选具有在0.1-100μm范围内的粒径(颗粒直径)，特别是0.3-60μm，非常特别优选为0.5-15μm。这里组分A和B的颗粒可以相同或不同。组分A和B的颗粒优选在组成以及粒度(颗粒直径)分布和D90值方面完全相同，仅仅在各自表面上具有不同的涂层。
D90值表示粒径(颗粒直径)，用激光衍射法测定，90体积％的颗粒至多具有该值。
在本专利申请中的涂层是指在组分A的情况下在各种情况中用TiO2和SiO2对球形基础颗粒的完全覆盖和在组分B的情况下在每种情况中用TiO2和铁氧化物对球形基础颗粒的完全覆盖。
组分A的球形基础颗粒在表面上(第一层)涂覆有TiO2。这里的TiO2可以是金红石或锐钛矿变体(modification)，优选锐钛矿型。TiO2层优选具有10-500nm的层厚度，特别是25–400nm，并且非常特别优选为50–300nm。这里的层厚度不仅取决于涂层参数，而且还取决于SiO2球的球尺寸。球越小以及因此球的表面积越小，对于存在的相同涂层参数施涂的TiO2越厚。仅球体的直径加倍可以导致TiO2层厚度减半，其在上述的0.5-15μm的粒度分布的范围内。
随后将SiO2层施涂到TiO2层。这个最终的SiO2层特别是用于改进分散性、化学和光化学稳定性和皮肤触感。SiO2层优选具有10–500nm的层厚度，特别是25–400nm，并且非常特别优选为50–300nm。
组分B的球形基础颗粒在表面上(第一层)涂覆有TiO2。这里的TiO2可以是金红石或锐钛矿变体，优选锐钛矿型。随后将铁氧化物层(例如包括Fe2O3或者Fe3O4，优选Fe2O3层)施涂到TiO2层。这里TiO2和铁氧化物层的层厚度可以相同或不同。
TiO2层优选具有50-400nm的层厚度，特别是200–400nm，并且非常特别优选为100–200nm。铁氧化物层优选具有5-300nm的层厚度，特别是10–200nm，非常特别优选为20–100nm。取决于层厚度和随后的煅烧，可以设置从黄色、褐色至红色色调的各种颜色。
然而，组分B的涂层也可以是TiO2和铁氧化物的混合物。该混合物优选由TiO2/Fe2O3和/或由铁板钛矿Fe2TiO5组成。TiO2/铁氧化物的混合物优选具有55-700nm的层厚度，和非常特别优选120–300nm。
特别优选的根据本发明的颜料混合物的组分A和B的表面上具有以下涂层：
球形基础基材+TiO2+SiO2
球形基础基材+TiO2+Fe2O3
球形基础基材+TiO2/Fe2O3
球形基础基材+Fe2TiO5。
组分A的颜料和组分B的颜料可以任何比例彼此混合。对于在特定应用中的色彩优化，优选组分A与组分B的混合比(重量份)为99:1至90:10，特别是98.5:1.5至95:5，和非常特别优选98:2至96:4。此处的混合比基于重量计。
根据本发明的颜料混合物通常具有10-200g/100g的吸油值，特别是20-200g/100g，非常特别优选为50-150g/100g。在本专利申请中的吸油值是根据DIN ISO787/5-1980(E)测定。
根据本发明的颜料混合物通过实现更简单的应用和在皮肤上更均匀的分散和改善皮肤触感来改进特别是化妆品的质地。由于根据本发明的颜料混合物是基于无毒的矿物基础构建的，并且主要包括无机组分，因此其非常好地被皮肤耐受。
球形基础颗粒的覆盖可以一壶法进行。根据本发明的颜料可以各种方式简单地制备。球形颗粒可通过湿化学法涂覆或通过CVD或PVD法用一个或多个涂层覆盖。
组分A和/或B的球形基础颗粒的覆盖优选在湿化学法中通过从其盐溶液水解沉积金属氧化物或金属氢氧化物来进行。
组分A或组分B的球形颗粒上的金属氧化物层优选通过湿化学法施涂，其中通常可以使用为制备珠光颜料而开发的湿化学法涂覆方法。这种类型的方法描述于例如US 3087828、US 3087829、US 3553001、DE 14 67 468、DE 19 59 988、DE 20 09 566、DE 22 14 545、DE 22 15 191、DE 22 44 298、DE 23 13 331、DE 25 22 572、DE 31 37 808、DE 31 37 809、DE 31 51 343、DE 31 51 354、DE 31 51 355、DE 32 11 602、DE 32 35 017、DE 196 18 568、EP 0 659843中，或者还在进一步的专利文献和本领域技术人员公知的其他出版物中。
在湿化学法涂覆的情况中，将组分A或组分B的球形颗粒悬浮在水中，并在适合于水解的pH下添加一种或多种可水解的金属盐，选择其使得金属氧化物或金属氧化物水合物直接沉淀到球上。通过同时计量加入碱或酸使pH值通常保持不变。随后分离出颜料，洗涤并干燥(优选在50-350℃下、特别是80-150℃下)，以及任选地煅烧，其中在每种情况下可以相对于存在的涂层优化煅烧温度。通常，煅烧温度是在250和1100℃之间，优选350和900℃之间。根据煅烧温度，可以实现黄色、褐色和红色的色调。特别是在煅烧温度>700℃下，黄色色调占优势，因为在组分B的情况下，由氧化钛和铁氧化物形成混合氧化物，例如铁板钛矿。
如果需要，可以在施涂单独的涂层之后分离颜料，洗涤以及任选地煅烧，然后再重新悬浮用于其它层的沉淀或以建立最终的色调，例如向TiO2/SiO2涂覆的颗粒悬浮液添加TiO2/Fe2O3-涂覆的球形颗粒。
涂层还可以进一步在流化床反应器中通过气相涂覆进行，其中可以相应使用例如在EP 0 045 851和EP 0 106 235中建议的用于制备珠光颜料的方法。
对于最终SiO2层的施涂，优选使用DE 196 18 569中描述的方法。对于制备SiO2层，优选采用钠或钾的水玻璃溶液。
当已经沉淀所需量的层材料时，中断反应，并设置适合于处理(work-up)的pH，例如pH为5。
对于处理，滤掉涂覆的球形颗粒，用水洗涤，并优选在50-150℃的温度下干燥1-20小时，并任选在350-950℃的温度下煅烧0.1-2小时。最后，筛分组分A或组分B的颜料或者颜料混合物。在最后步骤中，如果还没有进行混合，将经分离处理的组分A和B以所需比例彼此混合-如上所述-在悬浮液中。
通过选择不同的涂层材料和由此产生的覆盖率或层厚度和所使用的煅烧温度，组分A和B的色调和遮盖力可在较宽的范围变化。在纯粹选择用量之外，通过在视觉或测量技术控制下接近所需的色彩，可以实现微调某个色调。
为了增加光、水和气候稳定性，经常可取的是，根据应用领域，对组分A或组分B的颜料进行后涂覆或后处理。合适的后涂覆或后处理方法例如是在德国专利22 15 191、DE-A 31 51 354、DE-A 32 35 017或者DE-A 33 34 598中描述的那些。这种后涂覆进一步提高化学和光化学稳定性或者使颜料混合物的处理特别是掺入到各种介质更容易。为了改进润湿性、分散性和/或与施用介质的相容性，可以向颜料表面施涂包含Al2O3或者ZrO2或其混合物的功能性涂层。此外，有机后涂覆是可能的，例如用硅烷，例如在EP 0090259、EP 0 634 459、WO99/57204、WO 96/32446、WO 99/57204、US 5,759,255、US 5,571,851、WO 01/92425或者在J.J.Ponjeé,Philips Technical Review,第44卷,No.3,81ff.和P.H.Harding,J.C.Berg,J.Adhesion Sci.Technol.第11卷No.4,第471-493页中所描述的。
本发明还涉及根据本发明的颜料混合物的制备方法。
根据本发明的颜料混合物与多种色彩体系相容，优选来自油漆、涂料和印刷油墨领域。许多粘结剂，特别是水溶性产品，例如BASF、Marabu、、Sericol、Hartmann、Gebr.Schmidt、Sicpa、Aarberg、Siegwerk、GSB-Wahl、Follmann、Ruco或者Coates Screen INKSGmbH销售的，适合于制备用于例如凹版印刷、柔版印刷、胶版印刷或胶印套印抛光(offset overprint varnishing)的印刷油墨。印刷油墨可以是水基或溶剂基的。
可以用根据本发明在各种应用介质中显示为在0.5-15μm粒度范围的颜料混合物实现特别有效的作用，例如表面平滑和凹凸处的平整(皱纹、毛孔、凹陷、微裂纹等)，所述各种应用介质例如日用品配制剂如指甲油、唇膏、粉饼、啫哩、洗剂、肥皂、牙膏，油漆，工业涂料和粉末涂料，和塑料及陶瓷。
由于良好的皮肤触感和很好的皮肤粘附性，根据本发明的颜料混合物特别适合作为装饰性化妆品中的填料，也用于个人护理应用，例如身体乳液、乳剂、肥皂、洗发水等。
如所希望的，根据本发明的颜料混合物具有稳定化作用，例如在乳膏、乳剂和乳液中。

根据本发明的颜料混合物当然也可以在配制剂中与任何类型的化妆品原料和助剂结合。这些包括特别是油，脂肪，蜡，成膜剂，防腐剂，和通常确定应用性质的助剂，例如增稠剂和流变添加剂，如膨润土、锂蒙脱石、二氧化硅、硅酸钙、明胶、高分子量碳水化合物，和/或表面活性助剂等。
