Embodiment 1
[0022] A method for preparing a wear-resistant and anti-corrosion UV curing composite coating for metal parts, comprising the following steps
[0023] 1) Resin monomer synthesis: dimerized fatty acid (DA), glycidyl methacrylate (GMA), hydroquinone and benzyltriethylammonium chloride in a molar ratio of 200:200:5:2 Stir at a constant temperature of 120°C and 120r / min for 2 hours in a container with a condensing reflux device. After cooling to room temperature, mix the above synthesized liquid with isocyanatopropyltriethoxysilane (IPTS) in a molar ratio of 1:2 under nitrogen protection Stir at a constant temperature of 70°C and 120r / min in a container for 4 hours, and then obtain the resin monomer after cooling to room temperature;
[0024] 2) Weigh each raw material according to the following parts by weight: 100 parts of resin monomer, 0.5 part of thermal curing accelerator, 5 parts of photoinitiator, 15 parts of modified metal powder, 15 parts of graphite powder, 20 parts of ...
