Abstract
The invention discloses a preparation method of a polymer medicine package material, and relates to the field of package materials. The preparation method comprises the following steps: adding polyvinyl chloride (PVC), polypropylene, and polystyrene into a reactor, mixing under heating until the raw materials are evenly mixed; raising the temperature of the reactor to 150 to 200 DEG C, after the temperature is stable, adding polycarbonate and polyethylene glycol terephthalate with a ratio of 1:1 into the mixture prepared in the step (1), mixing again to obtain a mixed package material; carrying out extrusion moulding, cooling, heating the material to a temperature of 140 to 160 DEG C after cooling, maintaining the temperature for a while, then stretching the material, and finally packing the package material in bags to obtain the polymer package material. The provided technology is simple and reasonable, the yield is high, and the production cost is low.
Description
Technical field
The present invention relates to wrapping material field, particularly a kind of preparation method of polymer drug packing material.
Background technology
The application of polymeric packaging material is very many, has very many uses in medicine.The use of barrier to wrapping material of wrapping material has comparatively outstanding effect.Barrier is poor, and after long-time placement, the material in wrapping material has and oozes out, or the small-molecule substance in the external world can enter wrapping material inside, and these all have larger restriction to the use of wrapping material.The preparation method of polymeric packaging material of the prior art is complicated, and obtained rate is lower, and production cost is higher.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of preparation method of polymer drug packing material, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technical scheme: a kind of preparation method of polymer drug packing material, comprises the following steps:
(1) open reactor, in reactor, add polyvinyl chloride, polypropylene, polystyrene, carry out heating mixing, be mixed to evenly;
(2) temperature of reaction kettle is elevated to 150-200 DEG C, after temperature-stable, the polycarbonate adding equal proportion in mixture prepared by step (1) mixes stupid naphthalate again with poly-, obtains hybrid packed material;
(3) extrusion molding is carried out to hybrid packed material;
(4) cool extruding the material obtained;
(5) cooling after again by heating materials to 140-160 DEG C, stretch again after insulation;
(6) wrapping material being carried out dress bag, is the polymeric packaging material of preparation.
Preferably, in described step (2), temperature of reaction kettle is elevated to 200 DEG C.
Preferably, again by heating materials to 150 DEG C after cooling in described step (5), enter again after insulation
Row stretches.
Technical scheme beneficial effect of the present invention is adopted to be: by adding polyvinyl chloride, polypropylene, polystyrene in reactor, carry out heating mixing, be mixed to evenly, temperature of reaction kettle is elevated to 150-200 DEG C, after temperature-stable, the polycarbonate adding equal proportion in mixture prepared by step (1) mixes stupid naphthalate again with poly-, obtains hybrid packed material; Extrusion molding, cooling, after cooling again by heating materials to 140-160 DEG C, stretch after insulation, wrapping material are carried out dress bag, prepare polymeric packaging material, this invents the technique advantages of simple that provides, and obtain rate high, production cost is low again.
Embodiment
A preparation method for polymer drug packing material, comprises the following steps:
(1) open reactor, in reactor, add polyvinyl chloride, polypropylene, polystyrene, carry out heating mixing, be mixed to evenly;
(2) temperature of reaction kettle is elevated to 200 DEG C, after temperature-stable, the polycarbonate adding equal proportion in mixture prepared by step (1) mixes stupid naphthalate again with poly-, obtains hybrid packed material;
(3) extrusion molding is carried out to hybrid packed material;
(4) cool extruding the material obtained;
(5) again by heating materials to 150 DEG C after cooling, stretch again after insulation;
(6) wrapping material being carried out dress bag, is the polymeric packaging material of preparation.
Based on above-mentioned: adopt technical scheme beneficial effect of the present invention to be: by adding polyvinyl chloride, polypropylene, polystyrene in reactor, carry out heating mixing, be mixed to evenly, temperature of reaction kettle is elevated to 150-200 DEG C, after temperature-stable, the polycarbonate adding equal proportion in mixture prepared by step (1) mixes stupid naphthalate again with poly-, obtains hybrid packed material; Extrusion molding, cooling, after cooling again by heating materials to 140-160 DEG C, stretch after insulation, wrapping material are carried out dress bag, prepare polymeric packaging material, this invents the technique advantages of simple that provides, and obtain rate high, production cost is low again.
Obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
Claims (3)
