| Abstract: | The calcium stearate-PE wax lubrication system was optimized through rheological test, and a best formula was obtained, which contained PVC 100, calcium carbonate 13.3, CPE 11.5, stabilizer 3.87, titanium pigment 4, ACR 2.47, phthalocyanine blue 0. 000 93, whitening agent 0. 187, PE wax 0.36, and calcium stearate 0.2 parts. Dry blends with this formula showed heat stability time 19.27 min, plasticizing torque 26.57 N ·m, plasticizing time 122 s, good releasing property, non-adhersion to mold, suitable plasticizing degree and good hardnes.s and toughness. |
