Description
Technical field
The invention belongs to wrapping material field, particularly a kind of polypropylene film wrapping material and preparation method thereof.
Background technology
Polypropylene (PP) is a kind of thermoplastic resin being made by propylene polymerization, is divided into three kinds of isotatic polypropylene, Atactic Polypropelene and syndiotactic polypropylenes.Polypropylene film is often used as flexible packing material, and its consumption is only second to polyethylene, but existing polypropylene material mainly exist polarity lower, even there is the problems such as absciss layer with poor, the easy foaming of sticking power of ink.The frictional coefficient of polypropylene film material is too large, can not meet the requirement of automatic packaging production line, the surface resistivity of film is larger, easily produces static, and certain density organic solvent all can be contained in general soft packaging workshop, can bring the problems such as potential safety hazard like this.
In order to address these problems, people add slipping agent in PP resin, to increase the polarity of PP film, improve the frictional coefficient of ink adhesion, reduction film, but the problem that organic solvent exceeds standard never has good terms of settlement, the small molecules chemical substances such as while slipping agent, static inhibitor likely move in packaged food, carry out hidden danger to food securing band.
Summary of the invention
The invention provides a kind of polypropylene film wrapping material and preparation method thereof, polypropylene film wrapping material of the present invention can adhere to ink is fine, can meet the requirement of all kinds of automatic packaging production lines, and have reduced the occurrence probability of static.
Object of the present invention can be achieved through the following technical solutions:

Tetramethyl-monoammonium sulfate 2-4 part,
Graphene 0.05-1.5 part.
The percentage of grafting of described maleic anhydride inoculated polypropylene is 20-35%.
The average molecular mass of described polyoxyethylene glycol is 4000-6000.
A preparation method for polypropylene film wrapping material, the method comprises the following steps:
(1) take polypropylene 75-90 part, maleic anhydride inoculated polypropylene 20-30 part, calcium stearate 10-25 part, cyclodextrin 5-18 part, vinylformic acid 2-4 part, tetramethyl-monoammonium sulfate 2-4 part and Graphene 0.05-1.5 part, be uniformly mixed;
(2) pour in reactor and stir 30-50min, be heated to 130-150 ℃, pressurization 0.65MPa, reaction 2-3h obtains polymer melt;
(3) in the product of step 2, add polyoxyethylene glycol 10-19 part, then extrude, pelletizing, dry, cut into slices;
(4) step 3 section is melt extruded, slab spooling, two-way stretch, cooling and shaping, obtain polypropylene film wrapping material.
In described step 1, stir speed (S.S.) is 320-550 rev/min.
The temperature that melt extrudes in described step 4 is 240-260 ℃, and described two-way stretch temperature is 110-115 ℃.
compared with prior art, its beneficial effect is in the present invention:
(1) sticking power of polypropylene film wrapping material of the present invention and ink is good, by having reduced the probability that bubbles and absciss layer occurs adding of maleic anhydride inoculated polypropylene.
(2) polypropylene film wrapping material of the present invention have added calcium stearate to have reduced the frictional coefficient of polypropylene film wrapping material, can meet the requirement of all kinds of automatic packaging production lines.
(3) polypropylene film wrapping material of the present invention have added a small amount of Graphene, due to the singularity of Graphene self structure, the material surface resistance making are reduced, and have solved electrostatic problem, have reduced the occurrence probability of potential safety hazard.
(4) each raw material of polypropylene film wrapping material of the present invention, by reasonably optimizing proportioning, makes the film of preparation have good mechanical property, and because raw material is all environment-friendly type, thereby carry out hidden danger can to food securing band.
