Description
Technical field
The present invention relates to polyethylene film field more particularly to a kind of polyethylene films with efficient printing effect.
Background technology
Plastic film is relatively broad in the application of packaging field, available for food packaging, electric equipment products packaging, daily necessities bag
Dress, garment packaging.Due to packaging object to be identified, this just needs to print plastic film, thin in plastics
The upper various information of film surface printing obtain for people.But most polyolefin plastics film belongs to nonpolar poly- at present
Close object, surface tension is relatively low, common ink or adhesive can not adhesion-tight, and then easy to wear come off, it is therefore desirable to
These films are surface-treated.What is be most widely used at present is exactly to carry out sided corona treatment to plastic film, generally speaking,
It is exactly by applying high frequency, high voltage power supply between metal electrode and corona processor, being allowed to generate electric discharge, then make air electric
From the substantial amounts of ozone of formation, meanwhile, high-energy electric spark impact film surface, under their collective effect so that plastics are thin
Film surface generates activation, so as to improve surface tension.It can be increased to by the surface tension of the polyolefin film of sided corona treatment
38 because up to/centimetre, although can be theoretically combined with ink, surface tension does not increase significantly always, attachment
Power cannot guarantee that combining closely for ink.In addition, corona method also has the following disadvantages：
Firstly, since the size of sided corona treatment Plastic film surface tension and the voltage levels, the electrode that are applied on electrode
The factors such as the distance between sided corona treatment roller are related, and should avoid between plastic film and sided corona treatment roller sandwiching sky
Gas, a whole set of corona unit is complicated, and cost is higher, and sided corona treatment is more troublesome, such as the practicality of Application No. 201320071027.0
A kind of plastic film corona unit disclosed in new patent, package unit process flow is more, is not easy to the quick production of film；
Secondly, there is a timeliness in sided corona treatment, particularly at hot and humid summer, plastic film corona
Surface tension attenuation ratio after reason is more serious, and standing time is long after treatment for plastic film, and surface tension also can be gradual
Decline or even since the surface tension of printing surface and non-printed side tends to be the same, the film roll of printing is easy to generation ink
It is counter to adhere in non-printing roll, there is anti-viscous phenomenon.Therefore, it is necessary to existing sided corona treatment film is improved.
The content of the invention
In view of this, it is an object of the invention to overcome the deficiencies of the prior art and provide it is a kind of can be with ink tight bond
Polyethylene film.
In order to solve the above-mentioned technical problem, the present invention is realized using following scheme：
A kind of polyethylene film with efficient printing effect, is made of each raw material of following weight parts：
300 ~ 370 parts of polyethylene；
50 ~ 70 parts of calcium carbonate granule；
30 ~ 47 parts of maleic anhydride；
20 ~ 25 parts of diluent；
11 ~ 17 parts of sorbic acid；
The diluent is alcoholic solvent；
Carry out the mixing of raw material in accordance with the following steps before film forming：By proportioning by polyethylene, calcium carbonate granule and maleic acid
Acid anhydride is kneaded, and then sequentially adds sorbic acid and diluent, addition time alternate 10 ~ 25min of sorbic acid and diluent.
The present invention adds the roughness of polyethylene film after film forming by the blending of polyethylene and calcium carbonate granule, with
Enhance the cohesive force of polyethylene film surface and ink, since polyethylene and calcium carbonate granule belong to two different phases, Malaysia
Acid anhydrides enhances the compatibility between polyethylene and calcium carbonate granule so that calcium carbonate granule is more closely combined with polyethylene
Together.The cohesive force on polyethylene film surface and ink is improved to increase roughness, although this achieve certain effect,
It is in film-forming technology process, having certain probability between polyethylene macromolecular and calcium carbonate granule, there is larger gap, prints
Ink cannot fill up these gaps when brush, and the presence in gap reduces the adhesive force between ink and polyethylene film,
Ink is subject to after extraneous friction easily to peel off separation, the accidental discovery of inventor, by being kneaded after the sorbic acid of addition,
Polyethylene macromolecular forms calcium carbonate granule netted package structure, so in addition to it can increase mechanical strength, moreover it is possible to reduce empty
The presence of gap, and cyclic structure can also be formed between polyethylene macromolecular so that with cyclic structure anchor can occur for ink molecules
Gu effect, further improves adhesive force.By being kneaded with alcohol diluent so that the surface of polyethylene film is formed
C=O functional groups, the surface free energy of polyethylene film are significantly improved, and contact angle becomes smaller, and wetability improves.Mixing process
In, the mixing that first carry out sorbic acid is added diluent and is kneaded again, if all raw materials are carried out at the same time mixing or sorb
After the addition sequence of acid and diluent is turned round, polyethylene film surface free energy can be suppressed instead, not risen significantly；
Temperature, time of mixing etc. make limited number of time experiment by the prior art and can determine that the present invention does not elaborate.
The polyethylene include low density polyethylene (LDPE), medium density polyethylene, high density polyethylene (HDPE) and crosslinked polyethylene, four
Ratio be 12 ~ 15：17：11~15：20~23.
Low density polyethylene (LDPE), medium density polyethylene, the property of high density polyethylene (HDPE) and crosslinked polyethylene are not only similar but also
Four kinds of polyethylene according to proportioning are mixed and are blended again with other components by difference, can substantially reduce in mixing process polyethylene and its
Mechanical resistance between its raw material improves the mechanical performance of polyethylene film.
Preferably, a diameter of 1 ~ 10 μm of calcium carbonate granule.
Preferably, the diluent includes methanol and ethylene glycol, and the ratio of the two is 1：5~8.Pass through methanol and ethylene glycol
Compounding, the increase at any time of polyethylene film surface free energy can be delayed and decayed so that the migration that ink will not be at any time
And it comes off.
Compared with prior art, the present invention has the advantages that：
1st, the present invention can significantly improve the attached of polyethylene film surface and ink on the premise of good mechanical properties are kept
Put forth effort, significant ink bonding effect has been reached by surface anchoring effect and high surface free energy；
2nd, the operation of the high cost of the highly energy-consumings such as corona need not be carried out, resource and cost is greatly saved.
