Along with the development of modern industry and the improvement of living standard, the demand of each industry on functional terraces is more and more extensive, and the performance requirement on terrace coatings is higher and higher, not only requires that the terraces are corrosion-resistant, clean and wear-resistant, but also puts forward higher requirements on VOC content.
The epoxy resin floor material has the performances of water resistance, chemical corrosion resistance, acid resistance, alkali resistance, oil stain resistance, pressure resistance and the like, has mechanical strength far higher than that of a concrete substrate, has enough protection effect on the floor, has low shrinkage of a paint film after construction and solidification, can be coated into a thick film at one time, has a plurality of advantages of good self-leveling property, beautiful appearance, good decoration and the like, and is the floor coating material with the mature technology and the largest market share at present. The polyurethane resin floor coating has strict requirements on construction environmental conditions such as temperature and the like, and occupies a small area in domestic markets. The solvent-free epoxy resin floor material does not contain organic solvent, so that the environment pollution is reduced, and the danger of combustion, explosion and the like is avoided, so that the solvent-free epoxy resin floor material is widely applied to modern industrial floors and meets various requirements.
However, the existing solvent-free epoxy resin floor coating has the problems of general wear resistance, easy surface graining after being used for a period of time, reduced gloss, even paint film wearing and the like, and is difficult to meet the high requirement of frequent use places on wear resistance. Related documents report that quartz sand and ceramic powder are used as non-metal wear-resistant aggregates or zirconia is used as metal wear-resistant aggregates to improve wear resistance. The zirconia beads have smooth surfaces, excellent toughness, impact resistance and wear resistance, 30-50 times of the wear resistance of glass beads, and high density, true specific gravity and hardness.
