The invention discloses a preparing method of an implant nanotube array with an implant material surface subject to secondary anode and broaching treatment and surface hydrophilicity. According to the technical scheme, the method comprises the steps that firstly, pure titanium or a titanium alloy is provided for machining and molding a dental implant base body, and the base body is subject to mechanical polishing, cleaning, drying, chemical polishing and drying; secondly, the implant base body is placed in an anode of an electrolytic tank to be subject to primary anode oxidization; thirdly, the implant base body subject to primary anode oxidization is placed in a solution to be corroded and oxidized; fourthly, after cleaning, secondary anode oxidization is carried out; fifthly, the base body is placed in a phosphoric acid solution to be subject to broaching; sixthly, after deionized water washing and drying, a contact angle test is carried out, and hydrophilic performance data are obtained; the method has the
