Examples

Embodiment Construction

[0038] According to the following composition ratio

[0039] Polyvinyl chloride resin (PVC) 100 kg

[0040] Dioctyl phthalate (DOP) 31kg

[0041] Dioctyl Sebacate (DOS) 10kg

[0042] Epoxy Octyl Soyate (ED 3 ) 5 kg

[0043] Phosphite (OHP) 1 kg

[0044] Calcium stearate (CaSt) 2kg

[0045] Zinc stearate (ZnSt) 0.3 kg

[0046] Stearic acid (HSt) 0.3 kg

[0047] Paraffin 0.5 kg

[0048] Nanoscale activated calcium carbonate (CaCO 3 ) 1.2 kg

[0049] Its production method is shown in the figure:

[0050] Among the above components, the polyvinyl chloride resin is sieved to remove impurities;

[0051] Other powders and plasticizers are beaten and ground in a ratio of 1:2 or 1:3 to make a paste for later use; the above-mentioned ingredient ratios are weighed and mixed, and kneaded by high mixing for 15 to 25 minutes;

[0052] It is extruded by a single-screw plastic extruder and blown into a film of the required specification;

[0053] Finally, the film is made into ba...
