Description
技术领域
本发明涉及3D打印工件,具体涉及一种防腐蚀3D打印工件的冷却水冷道及其制备方法。
背景技术
随着科学技术的不断发展,3D打印机也随之应运而生,3D打印能直接从计算机图形数据中生成任何形状的模具,从而极大地缩短了产品的生产周期,提高了生产率。由于3D打印机打印模具成型时的工作温度较高,随之生产出的模具需要经过冷却水冷道进行冷却、输出。
而3D打印机的冷却水冷道内腔形状不规则、尺寸长,而且冷道中的冷却水的温度会因模具的输送而升高且所打印模具的材料具有多样性。因此,导致3D打印机的冷却水冷道内容易堆积水垢且锈蚀严重,进而致使打印的模具不合格。
发明内容
本发明的目的是提供一种防腐蚀3D打印工件的冷却水冷道及其制备方法,该防腐蚀3D打印工件的冷却水冷道具有良好的抗腐蚀性能,能够保证多打印模具的合格率。
为了实现上述目的,本发明提供了一种防腐蚀3D打印工件的冷却水冷道的制备方法:先将基体剂、助熔剂、乳浊剂和密着剂加入到SiO2溶胶中进行搅拌得到混合液,将混合液灌入到3D打印工件的冷却水冷道中得到挂有混合液的3D打印工件;再述挂有混合液的3D打印工件先后依次进行烘干和烧结得到防腐蚀3D打印工件的冷却水冷道;
其中,相对于100重量份的SiO2溶胶,基体剂的含量为24-30重量份,助熔剂的含量为12-18重量份,乳浊剂的含量为3-6重量份,密着剂的含量为2-5重量份。

本发明中,助熔剂可以在宽的范围内选择,都是为了提高制得的防腐蚀3D打印工件的冷却水冷道的抗腐蚀效果,优选地,助熔剂选自氧化钠、氧化钾和氧化硼中的一种或多种。

本发明中,密着剂可以提高所制得的防腐蚀3D打印工件的冷却水冷道的表面光滑度,优选地,密着剂选自氧化钴、氧化镍、氧化铜和氧化钼中的一种或多种。
本发明中,SiO2溶胶作为溶剂,为了进一步提高制备过程中混合液在冷却水冷道内的渗透效果进而提高防腐蚀3D打印工件的冷却水冷道的制备效率、提高3D打印工件的冷却水冷道的防腐蚀性能,优选地,SiO2溶胶对的乳液颗粒尺寸为800-1000nm。
本发明中,为了使制得混合液的各物料之间混合均匀以提高防腐蚀3D打印工件的冷却水冷道的制备效率,优选地,搅拌的转速为1200-2000rpm,时间为0.5-1h。
本发明中,为了提高防腐蚀3D打印工件的冷却水冷道的制备效率,对挂有混合液的3D打印工件的冷却水冷道进行烘干,但是为了避免温度过高导致冷道表面鼓泡,优选地,烘干的温度为45-50℃,时间为5-6h。
本发明中,为了提高制得的防腐蚀3D打印工件的冷却水冷道的质量,优选地,烧结的温度为750-850℃,时间为1-2h。
本发明还提供了一种防腐蚀3D打印工件的冷却水冷道,该防腐蚀3D打印工件的冷却水冷道由上述的制备方法制备而成。
通过上述技术方案,本发明将基体剂、助熔剂、乳浊剂和密着剂加入到SiO2溶胶中进行搅拌得到混合液,将混合液灌入到3D打印工件的冷却水冷道中得到挂有混合液的3D打印工件;再将挂有混合液的3D打印工件先后依次进行烘干和烧结得到防腐蚀3D打印工件的冷却水冷道。通过该方法制得的防腐蚀3D打印工件的冷却水冷道具有良好的抗腐蚀性能,能够保证所打印模具的合格率。
