一种导电海绵充电辊及其制备方法
摘要：
本发明涉及充电辊技术领域，具体涉及一种导电海绵充电辊及其制备方法，该充电辊包括辊轴、套设于辊轴外侧的发泡导电海绵层、以及套设于发泡导电海绵层外侧的套管；所述辊轴为铝芯，所述铝芯的化学成分包括如下重量百分比的元素：Cu：1.60%-1.80%、Mg：2.30%-2.50%、Mn：0.40%-0.60%、Fe≤0.50%、Si≤0.50%，余量为Al和不可避免的杂质，杂质单个≤0.05%，总量≤0.15%。本发明的充电辊采用铝芯作为辊轴，具有优良的导电性、导热性和抗腐蚀性能，且密度低，强度高，塑性好，容易加工。
摘要（英）：

The invention relates to the technical field of charging rollers, in particular to an electric conduction sponge charging roller and a preparing method thereof. The charging roller comprises a rollershaft, a foaming electric conduction sponge layer arranged on the outer side of the roller shaft in a sleeving manner, and a casing pipe arranged on the outer side of the foaming electric conduction sponge layer in a sleeving manner. The roller shaft is an aluminum core, the aluminum core comprises, by weight percent, 1.60 to 1.80% of Cu, 2.30 to 2.50% of Mg, 0.40 to 0.60% of Mn, not larger than 0.50% of Fe, not larger than 0.50% of Si, and the balance Al and inevitable impurities. The amount of the single impurity is smaller than or equal to 0.05%, and the total amount is smaller than or equal to 0.15%. according to the charging roller, the aluminum core is adopted to serve as the roller shaft, excellent electric conductance, heat conductance and corrosion resistance are achieved, densityis low, strength is high, plasticity is good, and machining is easy.
