摘　　要：为了提高发光涂料的耐候性、耐酸碱性、耐油性、耐腐蚀性和力学性能以及余辉强度和余辉时间,对聚酯丙烯酸树脂和铝酸锶铕发光材料的制备方法进行了研究,并将发光材料分散于聚酯丙烯酸树脂中,制备出了高性能的发光涂料。结果表明:用无色透明且透光性良好、特别是紫外线透过率高、透湿性小且耐水性、耐酸碱性、耐候性和力学性能优良的聚酯丙烯酸树脂作为主要成膜物质,将铝酸锶铕发光材料分散于聚酯丙烯酸树脂中制成的发光涂料涂抹性能好,耐腐蚀性、耐油性、耐酸碱性和耐候性强,力学性能优良,余辉亮度强,用照度200 lx的D65光源照射4 m in的余辉亮度在10m in时为20 mcd/m2,在60 m in时为6 mcd/m2;制得的发光涂料余辉时间长,余辉时间在1 000 m in以上,为优质的发光涂料。The methods to prepare polyester acrylate resin and SrAl_(2)O_(4):Eu^(2+) luminous materials were investigated with respect to the climate resistance,acid and alkali resistance,oil- proof ability,corrosion resistance,mechanical properties,and intensity and lasting time of persistent luminescence of the luminous paint made of the same.Thus the luminous paint of good coating performance was prepared by dispersing SrAl_(2)O_(4):Eu^(2+) in the colorless and transparent polyester acrylate resin.The resulting luminous paint had good light-penetrating ability,especially high ultraviolet penetration and small humidity penetration rate,excellent water-proof and climate-proof ability,excellent resistance to acid and alkali,good mechanical properties,and strong after-glowing luminance.After irradiation using a D65 light resource(200 lx) for 4 min,the luminous paint had 10 min and 60 min after-glowing luminance as much as 20 mcd/m^(2) and 6 mcd/m^(2),respectively,showing good persistent luminescence ability.The after-glowing duration for the luminous paint was over 1 000 min,indicating its potential as excellent luminous material.
