| 摘要 |
The present invention relates to a light-degradable material for producing disposable medical appliances having main components of polypropylene resin and composite allochromatic agent, wherein the composite allochromatic agent is composed of photoinitiator and sensitizer. The photoinitiator contains ferric citrate (FeC<SUB>6</SUB>H<SUB>5</SUB>O<SUB>7</SUB>) and ferrous pentadione (FeC<SUB>5</SUB>H<SUB>8</SUB>O<SUB>2</SUB>), and the sensitizer contains hexachloroacetone (Cl<SUB>6</SUB>C<SUB>3</SUB>O) and acetylbenzene (C<SUB>8</SUB>H<SUB>8</SUB>O). The material of present invention is neither toxic nor polluted in producing or in using, and can rapidly change color while being irradiated by UV rays. Reuse of these medical appliances can be thereby avoided. When they are thrown away in nature, they will keep degrading and decay to powder within 45~75 days. They are desired substitutes of present material for producing disposable medical appliances. |
