Described lubricant is the one in ethylene bis stearamide, glyceryl monostearate, stearyl alcohol or stearic acid.
Described softening agent is hexanodioic acid fat.
Described oxidation inhibitor is ESC-1010 oxidation inhibitor.
The preparation method of PVC heat-shrinkable film, comprises the following steps:
1) raw material of above-mentioned parts by weight is taken;
2) 70 ~ 80 DEG C add in reactor polyvinyl chloride resin, auxiliary agent, lubricant, softening agent, oxidation inhibitor and with 160 ~ 220rpm rotating speed stir 5 ~ 10min;
3) reactor temperature is increased to 280 ~ 300 DEG C, Pressure Drop to below 90pa, react 1 ~ 3h with this understanding and obtain polymer melt, then the polymer melt of preparation is extruded, pelletizing, drying, obtain PVC polyester section;
4) section of above-mentioned PVC polyester is melt extruded, die head slab, slab spooling, two-way stretch, cooling and shaping, detect thickness, rolling, cutting and rewinding, packaging, finished product.
Described to melt extrude temperature be 275 ~ 280 DEG C, and described two-way stretch temperature is 110 ~ 116 DEG C, and described detect thickness is 45 ~ 50 μm.
Beneficial effect: the PVC heat-shrinkable film that the present invention is obtained by above-mentioned preparation method, the transparency is good higher than common PVC heat-shrinkable film, and shrinks evenly and shrinking percentage is high, is environmentally friendly shrink film.Preparation method of the present invention is simple, easy to operate, can realize scale operation.This PVC heat-shrinkable film may be used for food, electronics, machinery industry.
