Abstract

The invention discloses a preparation method of a wear-resistant and corrosion-resistant UV-curing composite coating for metal members. The preparation method comprises: 1) synthesizing a resin monomer; 2) weighing the following raw materials by weight: 80-100 parts of the resin monomer, 0.2-0.5 part of a thermal curing accelerator, 2-5 parts of a photoinitiator, 10-15 parts of modified metal powder, 10-15 parts of graphite powder, 15-20 parts of nanometer calcium carbonate, 1-2 parts of a dispersant, and 0.5-1 part of a coupling agent KH550; 3) adding the thermal curing accelerator and the dispersant to the resin monomer, stirring and mixing uniformly, and gradually adding the metal powder, the graphite powder and the nanometer calcium carbonate while adding the coupling agent KH550; 4) after adding the metal powder, the graphite powder and the nanometer calcium carbonate, stirring; and 5) adding the photoinitiator in a dark environment, uniformly stirring, and stirring homogenizing in a homogenizer. According to the present invention, the double-cured coating material is prepared with the renewable oil material, and the corrosion resistance of the ink is enhanced by adding the metal powder and the graphite.

Description

technical field [0001] The invention relates to the technical field of coatings for metal parts, in particular to a method for preparing a wear-resistant and anti-corrosion UV-cured composite coating for metal parts. Background technique [0002] The use of coatings has a history of thousands of years, and the market for coatings is huge and has a bright future. However, with the needs of the market and application fields, the performance requirements of coatings in many industries are also constantly improving, and coatings with a single performance can no longer meet the needs of society. UV metal coatings are widely used in metal sign decoration, can processing, metal decorative panel manufacturing, aluminum alloy door and window protection, and steel pipe temporary coating protection. With the continuous development of high technology, in industries such as hydraulic power, electric power and marine transportation, the working conditions of construction machinery, equip...
