Abstract

The invention discloses a high-activity and high-permeating-rate powder zinc impregnation agent. The powder zinc impregnation agent comprises the following raw materials of, by weight, 60-100 parts of zinc powder, 2-6 parts of sea-foam stone powder, 3-5 parts of aluminum powder, 1-2 parts of aluminum oxide powder, 1-3 parts of magnesium powder, 0.6-2 parts of cobalt powder, 0.4-1.5 parts of lead powder, 0.8-1.4 parts of aluminum stearate powder, 0.2-0.5 part of boron nitride powder, 0.5-1 part of silicon dioxide powder, 0.6-1.2 part of graphene powder, 0.1-0.3 part of a reinforcing agent, 0.2-0.4 part of a dispersing agent, 0.3-0.6 part of a conditioning agent, 0.8-1.2 parts of an activating agent, 0.6-0.9 part of accelerant and 0.3-0.6 part of a stabilizer. The zinc impregnation agent is high in activity, high in permeating rate and excellent in reuse performance, the thickness of the zinc impregnation layer is considerable and uniform, strength of combination with workpieces is high, hardness is high, wear-resisting and corrosion resisting properties are high, and appearance is excellent.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of chemical heat treatment of iron and steel surfaces, and in particular relates to a powder zinc sherardizing agent with high activity and fast penetration rate. [0003] 【Background technique】 [0004] Outdoor steel structures and fasteners, highway guardrails, bridges, plumbing appliances, construction hardware, automobiles, construction machinery and other steel parts, powder metallurgy products and steel parts used in chemical, marine, metallurgical, power generation and other projects, often A corrosion resistant protective layer is required. Zinc is the most commonly used chemical element in the surface protection of steel parts: hot-dip galvanized layer, the thickness is generally 15-130μm, the thickness of the component plane and corner coating is obviously different, the uniformity is poor, and it is not easy to control; the thickness of the electro-galvanized layer is generally At 5-25μm,...
