Phosphorescent synthetic resin material method for production thereof, and formed article |
摘要 |
Disclosed are a phosphorescent synthetic resin material capable of absorbing and accumulating light therein in the light and phosphorescing in the dark, a method for the production of the material, and a formed article or molded article made of the phosphorescent synthetic resin material. The phosphorescent synthetic resin material having a phosphorescent pigment, SrAl2O4, uniformly dispersed in the synthetic resin is obtained by mixing the synthetic resin with the phosphorescent pigment and an activator and kneading the resultant mixture at a temperature 10 to 20 DEG C. higher than the melting point of the synthetic resin. In a preferred embodiment, the resultant compound is extruded at a temperature 10 DEG to 20 DEG C. higher than the melting point of the synthetic resin under an extrusion pressure in the range of 50 to 130 kg/cm2 and the extruded strands are chopped to produce pellets. By injection molding or extrusion molding the produced pellets into a desired shape, the formed article of synthetic resin possessing outstanding phosphorescent properties is obtained.
