Embodiment

[0018] The specific preparation process of the preparation method of the zinc-nickel coating on iron products mentioned in the present invention is as follows:

[0019] a) Prepare mixed paint. The main ingredients of the paint are: 60% zinc powder, 35% nickel powder, 3% cobalt powder and 2% chromium powder. Appropriate auxiliary materials need to be added during the preparation process of the paint. The main components are: antirust agent, active agent, antifoaming agent and diluent; among them, the antirust agent is zinc aluminate, the active agent is silicone oil, the antifoaming agent is silicone defoamer, and the diluent is deionized water. The percentage distribution ratio of auxiliary materials is about 1:1.5:3.5:20; the percentage distribution ratio of the above-mentioned main materials and auxiliary materials is about 1:8; when in use, the main materials and auxiliary materials are added to the reactor for sufficient mechanical stirring, spare;

Abstract

The invention discloses a preparation method of zinc-nickel coating for ironwork. The preparation method includes the following steps: a, preparing and mixing coating; b, pre-processing the ironwork; c, applying the coating; d, performing an induction heating process; and e, post-processing the ironwork. The preparation method is reasonable in process arrangement and moderate in preparation cost, the ironwork is remarkable in performances of strength, rigidity, toughness, corrosion resistance and anti-oxidation due to the zinc-nickel coating, the bonding strength of the zinc-nickel coating and the ironwork is high, the ironwork is durable, and requirements of severe working environments for performances of the ironwork are satisfied.

Description

technical field [0001] The invention relates to a method for preparing a coating for iron products, in particular to a method for preparing a zinc-nickel coating for iron products, and belongs to the technical field of coatings. Background technique [0002] Because iron products are easy to oxidize and corrode, people usually plate a layer of other metal or alloy materials on the surface of iron products, such as: zinc, nickel, chromium, copper, cobalt, etc., to achieve or improve the corrosion resistance of the base metal , wear resistance, oxidation resistance and other aspects of performance. [0003] However, ordinary coating materials have shortcomings such as impermanence, easy aging, easy falling off or insufficient strength, and high temperature resistance, and during the coating process, the coating will produce toxic substances that are harmful to human health or environmental safety. The coating process has been continuously improved and perfected, but the compo...
