Water-base metal antirusting agent and preparation method thereof

The invention relates to a water-base metal antirusting agent and a preparation method thereof. The antirusting agent comprises the components by weight percentage of 1-3% of dicarboxylic acid, 3-4% of triethanolamine, 0.5-1% of monoethanolamine, 5-10% of synthesized borate, 3-10% of polyethylene glycol, 1-3% of antiseptic, 0.1-1% of benzotriazole and the balance of water. The preparation method mainly comprises the following steps of: firstly preparing an antirusting agent body and subsequently adding and mixing the antiseptic, the polyethylene glycol, benzotriazole and the like, thus preparing the antirusting agent. In the invention, the action mechanism is simple and scientific, the cleaning and antirusting effect achieves the best by the cooperative function of all components; the antirusting agent contains the antiseptic that can effectively prevent the antirusting agent from cankering during the memory and working process, the polyethylene glycol can help forming film so that theantirusting agent has good water-repellent function and the antirusting capability can be effectively improved.
