[0055] Table 3 Modified masterbatch material ratio and parameter control
[0056]
[0057] Material Description:
[0058] Oleic acid: molecular weight 282.46, melting point 13-14°C;
[0059] Palmitoleic acid: molecular weight 254.41, melting point 0.5°C;
[0060] Soybean oleic acid: 280≤molecular weight≤284, melting point 15℃.
[0061] 【Preparation】
[0062] Add the main solvent 2 and anti-seepage agent in the formula amount into the small reaction kettle, stir at 50°C for 20 minutes to dissolve completely, then add the silane coupling agent and modifier in turn, maintain the temperature and continue stirring for 40 minutes, and naturally drop to After room temperature, ultrasonically treat for a certain period of time to obtain activated modified masterbatches, which are respectively recorded as masterbatch 1, masterbatch 2, masterbatch 3, masterbatch 4, masterbatch 5, masterbatch 6, masterbatch 7, and ma...
