Abstract

The invention discloses a making process of a plastic thin film. The making process is characterized in that the plastic thin film is composed of 55-95% of polypropylene, 2-30% of maleic anhydride grafted modifier of polyolefin and 0.5-30% of agent masterbatch, and the agent masterbatch comprises 0-2% of anti-bonding agent, 0-5% of antistatic agent, 0-20% of extinction masterbatch and 0-20% of titanium dioxide and calcium carbonate. The plastic thin film has higher applicability, and a stretch thin film can be formed through low-temperature heat sealing of lower-cost paper and the plastic thin film or the plastic thin films; when the plastic thin film is laminated with paper or other thin films, glue coating is not needed, laminating can be completed by enabling a low-temperature heat sealing layer to contact with a laminated object, and no toxic gas is generated during laminating.

Description

A kind of preparation technology of plastic sheeting
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 suitability wider, the oriented film of Low Temperature Thermal sealing between paper and plastic sheeting or plastic sheeting that cost is lower, when this thin 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 chiller 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 thin 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 stretchs, 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.
