New Luminescent Coating Wear Resistance

Along with the development of modern science and technology and our country's transportation enterprise. The quantity of the road, the highway, the urban road increasgreat. the use of road sign paint also increase day by day along with it The automobile receives the mixed grit during the travel, as well as wind and rain washing out, the coating are attrited quite seriously. At present the uses the of road sign paint all has certain malpractice. The experiment is to conduct the research of resistance of luminated coating. Develops new wear-resisting luminating coating , this article is to use the polyurethane and the epoxy resin as the membrane matter, the epoxy resin carries on the response, produces new contained the hydroxyl resin component, the component and the polyurethane which contanning the -NCO groups have chemical reaction, becomes the split-ring epoxy to gather the amine ester coating.Studies the SrAI₂O₄:Eu²⁺ to the coating wear resistant, discovered when burnishing powder amount used between 20% and 40%, the varnish film attrition weightlessness reduction scope is bigger, along with sends when the burnishing powder amount used continues the increase, the varnish film attrition weightlessness reduction amplitude variation is not obvious, when high potency draws close to a constant. Through the XRD, the Laman spectrum, IR, discovered sends the burnishing powder to join all in the coating membrane, spreads the membrane and sends the burnishing powder the characteristic absorption all to have the certain change. Through to this phenomenon discussion, extrapolated sends the burnishing powder to push spreads the membrane resistance to wear influence the action mechanism. Through Laman spectrum, HITACHI (Hitachi) F-4500 fluorescence luxmeter research coating luminescene characteristic. Through SEM observe coating attrition appearance .
