A kind of preparation method of antistatic biodegradable package film, it comprises the following steps:
(1) mica powder 200-300 DEG C being processed 3-6h, add corn starch, Semen arachidis hypogaeae dregs and peanut hull meal after cooling, co-ground is uniform, crosses 300-400 mesh sieve, obtains mixed powder；
(2) mixed powder obtained in (1) is added in dehydrated alcohol by solid-liquid weight ratio 1:3-1:4, first ultrasonic disperse 10-15min, adds lauric acid amide of ethanol and pentaerythritol stearate, is heated to reflux processing 3-5h, cooling final vacuum extracting removes solvent, obtains mixed material；
(3) first by the mixed material obtained in (2) and tributyl 2-acetylcitrate common mixed at high speed 10-20min under the conditions of 80-100 DEG C, add polyglycerol polyricinoleate, calcium stearate, erucyl amide and polypropylene mixed at high speed 15-30min under the conditions of 120-140 DEG C, obtain mixed resin；
(4) mixed resin that obtain in (3) is added double screw extruder, control temperature in 150-180 DEG C of extrusion, after cooling granulation and get final product.
Wherein, utilize lauric acid amide of ethanol and pentaerythritol stearate that the inserts that corn starch, Fructus Cucurbitae moschatae powder, corn straw, blanc fixe etc. are primary raw material is modified, the dispersibility of reinforcing filler, strengthens the raw-material compatibility, intensified waterproof performance；Pentaerythritol stearate, polyglycerol polyricinoleate, erucyl amide improve the antistatic performance of material by synergism；Calcium stearate, erucyl amide can play collaborative lubrication, auxiliary plasticization.
The invention have the advantage that
1. by the improvement of formula with technique, the packaging film prepared is made to have good biodegradability properties energy, Heat stability is good, antistatic performance is good, and there is certain resistance to water and the most wear-resisting, corrosion resistance, being effectively increased the use safety coefficient of material, serviceability is good, it is adaptable to the occasion of antistatic particular/special requirement；
2. the primary raw material used is with low cost, and raw material is easy to get, and processing technology is simple, safety non-toxic, meets the requirement of environmental protection and energy saving.
