Description

一种耐高温的塑胶颜料组合物
技术领域
本发明涉及一种颜料，尤其涉及一种耐高温的塑胶颜料组合物。
背景技术
塑胶颜料是指赋于塑料各种颜色以制成特定色泽的塑料制品的一种工业用品。塑胶颜料应能经受塑料加工成型处理中的各项工艺条件，以制成特定色泽的塑料制品。因此塑胶颜料应当具有良好的色彩性能以及易分散性和耐热性。为了增加塑料产品的商品价值，从之前单纯追求美观，发展到对着色产品安全性、稳定性和高性能等提出了更高的要求，因此塑胶颜料还应当在塑料制品使用条件下具有良好的无毒性、耐候性、耐迁移性、耐化学药品性等应用性能。目前使用的塑胶颜料大多不具备高温稳定性，不适合较高温条件下加工的塑料，如工程塑料ABS、HDPE等的着色，而有耐高温性能的塑胶颜料的分散性较差，限制了塑胶颜料的应用。
发明内容
针对现有技术不足，本发明提供了一种高温稳定性及分散性良好的塑胶颜料组合物。
本发明解决上述技术问题采用的技术方案为：一种耐高温的塑胶颜料组合物，包括以下重量份数的原料：着色粉8～15份、EVA蜡1～3份、聚四氟乙烯微粉3～7份、苯甲酸钠1～2份、抗氧剂DNP0.5～1份、聚乙烯吡咯烷酮0.5～1份、硬脂酸钙0.5～1份、纳米级羟基磷灰石粉1～2份、钛白粉0.5～1份、分散剂NNO2～4份及分散剂MF1～3份；
所述的着色粉为钴蓝、钴绿或钛镍黄。
进一步地，所述一种耐高温的塑胶颜料组合物，包括以下重量份数的原料：着色粉12份、EVA蜡2份、聚四氟乙烯微粉5份、苯甲酸钠1.5份、抗氧剂DNP0.7份、聚乙烯吡咯烷酮0.7份、硬脂酸钙0.8份、纳米级羟基磷灰石粉1.5份、钛白粉0.8份、分散剂NNO3份及分散剂MF2份。
具体的，在使用过程中，将上述原料充分混合均匀并根据使用需要，与少量载体树脂如聚乙烯蜡、EVA蜡、氧化聚乙烯蜡、聚丙烯蜡或者需要着色的塑胶进行预混合、螺杆挤出、切粒、干燥等操作制备成色母粒料，利用色母粒料进行塑胶的着色加工。
与现有技术相比，本发明具备的有益效果：本发明提供的一种耐高温的塑胶颜料组合物采用环保性的原料混合而成，环保性能优良；在使用过程中的分散性良好，保证了着色体表面的细腻光滑及内部着色的均匀性；本发明的塑胶颜料组合物耐热稳定性良好，耐热温度可达300℃，适用于须较高温条件下加工的塑料如工程塑料ABS、HDPE等的着色；实用性广，与塑质材料的相容性较好，可适用于各种需要着色加工的塑质材料并对塑质材料无结构性影响，保持塑质材料原有的特质；同时本发明的塑胶颜料组合物使用方便，着色加工操作简便，着色效果好。
