Description
Technical field
The invention belongs to technical field of macromolecules, be specifically related to a kind of wear-resisting epoxy coating that can be used for prosthetic appliance, pipeline.
Background technology
Epoxypaint is of many uses, and its shrinking percentage is low, cohesive strength is high, preparation is easy, technique is simple, cured article hardness is high, modification is easier to, and various metals and most of non-metallic material are all had to good sticking power.
Two-phase fluid erosive wear is to cause one of major reason that equipment, Pipeline damage scrap, and the high-abrasive material kind of domestic and international application has alloy material, inorganic materials (as silicon carbide, high alumina ceramic etc.), organic materials (as urethane, nylon, rubber etc.) at present.Alloy material has heat resistant and wear resistant performance, but its density is large, moulding is complicated, cost is high, site operation is difficult; Although inorganic materials has very high wear resistance, along with the increase of its hardness, fragility also increases, and on-the-spot use is easily hit and ruptures, and in machine-shaping process, scrap rate is high, and production energy consumption is high; Organic materials possesses certain wear resistance, lightweight, but its anti-solid particulate scratches ability.And above-mentioned three class materials all do not possess the function of repairing worn parts.
In epoxypaint, add filler not only can reduce costs, also can improve many performances of epoxypaint, as improved sticking power, compressive strength and wear resistance etc.The more employing silica powder of filler, lapis amiridis, talcum powder, light calcium carbonate etc.Existing epoxy group(ing) wear-resistant paint, be generally in epoxypaint, to add the mechanically resistant materials such as the antifriction materials such as graphite, molybdenumdisulphide and oxide compound, iron powder, aluminium powder, the epoxypaint forming is like this not enough to resist abrasive conditions and the environment of very severe.
