The treatment processes of the modified camellia oleifera shell powder in the above examples 1 to 5 are all as follows: s11, steaming the oil tea camellia shell in a sodium sulfite aqueous solution with the concentration of 3% -5%, washing, drying and crushing after 4-6h, adding dimethyl silicon oil, uniformly mixing, grinding and dispersing for 40-50 min, and drying to obtain modified oil tea camellia shell powder.
The preparation methods of the environment-friendly color master batches in the above embodiments 1 to 5 all include the following steps:
1) banburying: putting EVA waste and EVA rubber particles into an internal mixer for internal mixing until the EVA waste and the EVA rubber particles are agglomerated, and discharging;
2) grinding: placing the internally mixed material blocks into a three-roll grinder for thin passing, controlling the temperature to be 80-100 ℃, and controlling the distance between the three rolls to be 1-5 mu m to obtain a grinding material;
3) mixing: kneading low molecular weight polypropylene, pigment and modified oil tea shell powder in an internal mixer for 10-20 min, controlling the temperature at 90-100 ℃, then adding the grinding material and other components in the step 2) while the mixture is hot, and mixing the mixture at the temperature of 90-110 ℃ to obtain a mixed material;
4) cutting: cutting the mixed material obtained in the step 3) into small blocks of 25-35 cm (25-35) cm, and cooling the small blocks to room temperature;
5) open mixing: the material cut and cooled in the step 4) is milled on a mill, the temperature is controlled to be 90-110 ℃, cloth is drawn, the material is formed into a thin cloth shape of (25-35) cm x (25-35) cm, and the material is cooled for standby;
6) and (3) granulation: extruding the thin cloth-shaped material obtained in the step 5) by using a double-screw extruder, shearing the extruded material strip into a strip of 5-10 cm by using a shearing machine, and granulating at 180-210 ℃ by using a granulator.
Comparative example 1
This comparative example 1 differs from the above example 1 only in that: the polypropylene of this comparative example had a molecular weight of 8000 and the camellia oleifera shell powder was supplemented with simethicone.
Comparative example 2
This comparative example 2 differs from the above example 1 only in that: this comparative example 2 does not first knead the low-molecular weight polypropylene, the pigment and the modified oil-tea hull powder in step 3), but directly kneads the millbase with the remainder.
The dispersibility index of the color master batch is evaluated by testing the b value with a tester of Meinen to 2500C, the b values of the examples 1 to 5 are all in the range of 42 to 45, while the b value of the comparative example 1 is 38.6, and the b value of the comparative example 2 is 40.2.
While there have been shown and described what are at present considered the fundamental principles and essential features of the invention and its advantages, it will be understood by those skilled in the art that the invention is not limited by the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
