This invention discloses a wear-resistant
alkyd resin coating and its preparation method, belonging to the technical field of
alkyd resin coatings. First, a mixed
vegetable oil is modified by epoxidation and ring-opening esterification to obtain a modified mixed
vegetable oil. Then, this modified oil is further modified by esterification condensation and hydrophilic modification to obtain a modified waterborne
alkyd resin. Simultaneously, modified nano-
cerium oxide is prepared by in-situ
precipitation using
phosphate betaine as a modifier. Finally, the modified waterborne alkyd resin, modified nano-
cerium oxide, and additives are mixed to obtain the wear-resistant alkyd
resin coating. This invention, through the synergistic effect of epoxidized
vegetable oil, anhydride ring-opening crosslinking network, and in-situ modified nano-
cerium oxide, solves the defects of traditional alkyd resin coatings, such as insufficient
wear resistance, difficulty in balancing rigidity and
toughness, and easy agglomeration of fillers. It endows the
coating with excellent
wear resistance, high
hardness, good adhesion, and flexibility, meeting the high-standard wear-resistant protection requirements of
mechanical equipment and
steel structures.
