Abstract
A preparation technology of a plastic film is characterized in that the plastic film comprises the following ingredients in percentages by weight: 55-95% of polypropylene, 2-30% of maleic anhydride graft modification substances of polyolefin and 0.5-30% of agent masterbatch; and the agent masterbatch contains the following components in percentages by weight: 0-2% of an anti-sticking agent, 0-5% of an antistatic agent, 0-20% of extinction masterbatch, and 0-20% of titanium dioxide and calcium carbonate. The preparation technology of the plastic film has the features that the stretching film which is wide in applicability and low in cost, and is formed by low-temperature heat sealing of paper and the plastic film or by low-temperature heat sealing of the plastic films is provided; when the film is compounded with paper or other films, glue is not required, the film is in contact with a compounded object through a low-temperature heat sealing layer so that compounding can be finished, and toxic gas cannot be generated during compounding.
Description
Technical field:
The present invention relates to the preparation technology of a kind of plastic sheeting.
Background technology:
At present, paper plastic structure is poor to the adaptability of paper, narrow application range, and glue-free composite membrane processing cost is high.
Summary of the invention:
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of applicability wider, the oriented film of Low Temperature Thermal sealing between paper and plastic sheeting or plastic sheeting that cost is lower, when this film and paper or other Film laminated, without glue coating, can complete to be combined by Low Temperature Thermal sealing and the object contact being combined, compound tense will not produce toxic gas.
The object of the present invention is achieved like this:
The preparation technology of a kind of plastic sheeting, it is characterised in that the dispensing of plastic sheeting is: polypropylene component is 55-95%, polyolefinic modified by maleic acid anhydride graft thing component is 2-30%, and masterbatch component is 0.5-30%,
The antitack agent component that described masterbatch comprises is 0-2%, and antistatic additive component is 0-5%, delustring masterbatch component be 0-20%, titanium dioxide and calcium carbonate components be 0-20%.
The preparation technology of a kind of plastic sheeting comprises the steps of
Dispensing adds in corresponding extruder 180 DEG C-280 DEG C carry out melting, plastifying, extrude and conflux in T-shaped or rack type die, by die head in 180 DEG C-280 DEG C extrusions；
The die head extrudate of supporting layer is cooled down through the cooling device of 10 DEG C-60 DEG C, forms diaphragm；
Diaphragm carries out preheating through longitudinal stretching machine successively, longitudinal stretching and thermal finalization, 100 DEG C-170 DEG C preheatings, and longitudinal stretching multiplying power is 2-6, and draft temperature is 60 DEG C-160 DEG C, and the temperature of thermal finalization is 90 DEG C-170 DEG C；
Now, the resin of at least one of which low-temperature heat-sealing layered material molten condition flows out from another die head, to carry out melting, plastifying in the dispensings such as polyolefinic modified by maleic acid anhydride graft thing are added corresponding extruder equally, extrude and conflux in T-shaped or rack type die, extruded by die head, carry out that hot pressing is compound enters back into cross directional stretch preheated zone with the film after longitudinal stretching；
Through 100 DEG C-190 DEG C preheatings, cross directional stretch multiplying power is 6-12, draft temperature is 60 DEG C of-170 DEG C of cross directional stretch, and temperature range is 90 DEG C-190 DEG C and carries out thermal finalization；
The outermost layer of the supporting layer (side not contacted with Low Temperature Thermal sealing) of composite membrane after cross directional stretch is carried out conventional corona or flame treatment；
Rolling.
