The invention provides a preparation method of an aluminum alloy hub, as shown in Figure 1, the preparation method comprises the following steps: a die casting step: smelting an aluminum-silicon alloy and then carrying out high-pressure die casting treatment to obtain a die casting; coating is conducted, specifically, the die casting is subjected to coating treatment, and a coated part is obtained; the coating piece is subjected to infiltration and first curing in sequence, and the aluminum alloy hub is obtained; wherein infiltration liquid in the infiltration process comprises an acrylate compound and a curing agent. Through the preparation method, on the basis of further promoting the low cost and the high production efficiency of a workpiece, the high requirement of a vacuum tire for the compactness of the section of the hub can be met, and therefore when the aluminum alloy hub is used as the hub of the vacuum tire subsequently, the performance of the vacuum tire is better.
本发明提供了一种铝合金轮毂的制备方法,如图1所示,制备方法包括以下步骤:压铸步骤:将铝硅合金熔炼后进行高压压铸处理,得到压铸件;涂装步骤:对压铸件进行涂装处理,得到涂装件;浸渗步骤:对涂装件依次进行浸渗、第一固化,得到铝合金轮毂;其中,浸渗过程中的浸渗液包括丙烯酸酯类化合物和固化剂。通过上述制备方法,本发明在进一步促使工件具有低成本、高生产效率的基础上,还可以满足真空胎对轮毂截面致密性的高要求,进而使得本发明上述铝合金轮毂在后续作为真空胎的轮毂应用时,真空胎性能更优。
