MoS2 microparticle reinforced dacromet coating and coating method thereof

Abstract

The invention provides a MoS2 microparticle reinforced dacromet coating. The MoS2 microparticle reinforced dacromet coating is prepared through the following steps: subjecting 17-22 parts by weight ofaluminum powder, 74-79 parts by weight of zinc powder and 3.5-4.0 parts by weight of MoS2 microparticles to resonance sound mixing so as to obtain a mixed powder material; subjecting 70-75 parts by weight of the mixed powder material, 25-30 parts by weight of a wetting agent and 1.0-1.5 parts by weight of a dispersing agent to ultrasonic mixing so as to obtain a metal slurry; and mixing 42-45 parts by weight of the metal slurry, 1.5-3.0 parts by weight of water-soluble silicate, 0.5-1 part by weight of borate, 1-3 parts by weight of polytetrafluoroethylene, 0.5-1 part by weight of a silane coupling agent, 0.05-0.1 part by weight of magnesium salt, 0.2-0.5 part by weight of potassium titanate, 0.5-1.5 parts by weight of a passivator, 1.2-2.0 parts by weight of an auxiliary agent and 45-50parts by weight of deionized water, carrying out stirring for 60 to 90 min at a room temperature and a rotating speed of 60-100 r / min, and carrying out standing for 30-60 min at a constant temperaturein a water bath environment of 38 to 42 DEG C so as to obtain the MoS2 microparticle reinforced dacromet coating. The MoS2 microparticle reinforced dacromet coating prepared by using the method provided by the invention forms a coating layer on the surface of steel after being coated on the surface of the steel; and compared with a common dacromet coating, the MoS2 microparticle reinforced dacromet coating has stronger wear resistance.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment and relates to a MoS 2 Microparticle-reinforced dacromet paint and coating method thereof. Background technique [0002] Dacromet is the transliteration of dacromet, also known as zinc-aluminum coating, which is a new type of anti-corrosion coating with zinc powder, aluminum powder, chromic acid and deionized water as the main components. Dacromet technology is a surface coating technology with simple process and good anti-corrosion effect. As a new surface treatment technology, Dacromet technology is a "green electroplating" compared with the traditional electroplating process, which has the following advantages: stronger corrosion resistance, no hydrogen embrittlement, high heat resistance, bonding and penetration Good performance, non-polluting process, etc. Therefore, Dacromet has been widely used in various industries such as automobiles, bridges, electric power, railways, ...
