The invention discloses a carbon bearing or shaft sleeve for an electronic water pump of an electric vehicle and a preparation method thereof, and the preparation method comprises the following steps: uniformly mixing matrix powder obtained by uniformly mixing natural graphite, artificial graphite, graphite fluoride, pitch coke, carbon black and an additive with a binder pitch to prepare a raw material mixture; the raw material mixture powder obtained through crushing treatment is added into a pressing mold for pressing treatment, and a green material is prepared; and carrying out hot roasting treatment on the green material to obtain the carbon bearing or the shaft sleeve. The carbon bearing or the shaft sleeve is manufactured by adopting a compression molding process, has the characteristics of simple process, high product strength, good wear resistance, high dimensional stability and environmental friendliness, meets the General Safety Requirements for Food Contact Materials and Products of Food Safety National Standards and the FDA certification standard of the American Food and Drug Administration through food contact material detection, and has a wide application prospect. The water pump is suitable for various household appliance pumps such as dishwashers, beverage dispensers, coffee machines and constant-temperature hot water systems, and is particularly suitable for electronic water pumps of electric automobiles.
本发明公开了一种电动汽车电子水泵用炭轴承或轴套及其制备方法，包括：将天然石墨、人造石墨、氟化石墨、沥青焦、炭黑和添加剂混合均匀的基体粉料与粘结剂沥青混匀，制得原料混合物；将破碎处理得到的原料混合物粉末加入到压制模具中，进行压制处理，制得生坯料；对生坯料进行热焙烧处理，即得炭轴承或轴套。本发明炭轴承或轴套采用压制成型工艺制作，工序精简，产品强度高、耐磨性能好、尺寸稳定性高，具有绿色环保的特点，通过食品接触材料检测，符合《食品安全国家标准食品接触材料及制品通用安全要求》和美国食品和药品管理局FDA认证标准，适用于洗碗机、饮料机、咖啡机、恒温热水系统等多种家电泵，尤其适用于电动汽车电子水泵用。
