があつた。However, the epoxy resin composition is one in which a liquid resin is cured by adding a curing agent, and is initially a liquid having a relatively low viscosity, and has a higher specific gravity abrasion resistance than the epoxy resin as in the conventional method. Particles, for example, ceramic spherical peas, silicon carbide particles, etc. are mixed, even if terminally activated silane is used in combination, curing conditions such as one day at room temperature and 20 to 50 minutes at 100 to 140 ° C. In, the essential wear-resistant compounding material sinks to the bottom of the coating film or the matrix molding, and the surface portion that causes friction or impact becomes a portion where the concentration of the wear-resistant compounding material is low, and the effect is diminished. Not only that, but also there was a defect that the phenomenon of "drooping" was seen in the vertical part and ceiling part of the repaired part.

It is to be hardened together with, but at that time, a cotton-like ceramic containing alumina (Al 2 O 3 ) as the main component together with an abrasion-resistant compounding agent, called ceramic cotton (which also has abrasion resistance) is used, By suspending the wear-resistant compounding components on the cotton-like ceramic by mixing the liquid epoxy resin with other wear-resistant compounding agents, it is possible to prevent sedimentation or separation of the wear-resistant compounding components during the curing process. By mixing ceramic cotton, the viscosity increase is remarkably improved, vertical surface repair, "drip" drop during coating process is prevented, and a uniform coating film or molded product is formed, which is wear-resistant and antiseptic. To improve the effect of planting Is.
