Anti-UV plastic for automobile interior ornaments

The method to prepare the anti-UV plastic for automobile interior ornaments is characterized by that, it includes the following steps:

• S1 PC resin and ABS resin are dried respectively for 3˜5 h under 80˜85° C.;
• S2 PC resin, ABS resin, antioxygen, pentaerythritol stearate, inorganic filler, anti-UV fiber, organic silicon resin or modified organic silicon resin are weighed according to the formula, and mixed for 5-10 min at the speed of 3000-5000 rpm to get the mixture;
• S3 The mixture is put in the extruder to extrude out. The temperature of feeding segment of the extruder is 180˜190° C. The temperature of mixing segment is 230˜240° C. The temperature of machine head is 200˜210° C. The revolving speed of main machine is 80 100 rpm. Then, cooling and cutting into particles are conducted to get the anti-UV plastic for automobile interior ornaments.
