Embodiment 1
[0059] Embodiment 1: An anti-aging plastic film, the components and their corresponding parts by weight are shown in Table 1, and are prepared through the following steps:
[0060] Step 1: Put polyvinyl chloride, polychlorotrifluoroethylene, polycarbonate and phosphite in corresponding parts by weight into the reactor for constant temperature stirring, the stirring speed is 500rpm, the stirring time is 40min, and the temperature is maintained at 80°C ;
[0061] Step 2, adding fumed silica and fumed silica in corresponding parts by weight, stirring at a constant temperature, the stirring speed is 900rpm, the stirring time is 25min, and the temperature is maintained at 50°C;
[0062] Step 3, adding coconut shell fiber and bacterial cellulose fiber in corresponding parts by weight, stirring at a constant temperature, the stirring speed is 300rpm, the stirring time is 15min, and the temperature is maintained at 30°C to obtain the mixture;
Embodiment 2-8
[0065] Example 2-8: An anti-aging plastic film, the difference from Example 1 is that each component and its corresponding parts by weight are shown in Table 1.
[0066] Each component and parts by weight thereof in table 1 embodiment 1-8
[0067]
[0068]
Embodiment 9
[0069] Embodiment 9: A kind of anti-aging plastic film, the difference with embodiment 1 is that described bacterial cellulose fiber is modified, and the step of modification is as follows:
[0070] S1, take the bacterial cellulose fiber of corresponding parts by weight, soak in glacial acetic acid, the soaking time is 24h;
[0071] S2, then add concentrated sulfuric acid and 8:1 acetic anhydride with a corresponding weight and part ratio of 14:1, and carry out a constant temperature reaction for 30 minutes at a temperature of 75°C;
[0072] S3, then add the acetic acid solution that has been preheated to 50°C and the corresponding weight part ratio is 1:2, and carry out constant temperature reaction for 10min, the temperature is 60°C;
[0073] S4. Finally, add acrylamide with a molar ratio of 1:2 and a corresponding weight-to-number ratio of 4:1, and carry out a constant temperature stirring reaction for 4 hours at a temperature of 25°C and a stirring speed of 100 rpm to obta...
