| titleOfInvention | Resin Colouring Method Using Photochromic Powder |
| abstract | The present invention relates to a resin coloring method using a photo-compatible compound, a polypropylene (PP) or polyethylene (PE) of the extruded master pellet (Pellet) mixed for a predetermined time in a composition mixed with a photo-compatible compound in the organic solvent By injecting homogeneous penetration of photo-compatible compounds into the colorant resin by adding, it is possible to realize the expansion of the use of the resin molding and the quality of the quality through a variety of color changes, the present invention for this purpose 10-30% by weight of normal hexane, trichloro Photo-compatible to be dissolved in a mixed organic solvent consisting of 10-15% by weight of ethane, 15-20% by weight of methyl isobutyl ketone, 30-40% by weight of toluene, 5% by weight of methyl chloride, and 20-30% by weight of xylene A first step of providing 2-3% by weight of the compound; A second step of providing a polymer containing a surfactant after the first chemical reaction of 70 to 100% by weight of the composition passed through the first step for 30 to 40 / min; 0.02% by weight of light stabilizer and 0.03% by weight of antioxidant were added to the polymerization solution after the second step, and dissolved at 1, 2 / min at 600 rpm. Then, polypropylene (PP) and polyethylene (PE) resin were added to the colorant resin. A third step of performing a second chemical reaction at a pressure of 2.0 to 2.7 and a temperature of 70 to 100 ° C. for 10 to 20 / min; And a fourth step of sequentially drying the resin extracted after the third step at 30 to 90 / min at 70 to 90 ° C., as a feature of the technical idea. |
