Description
Technical field
The invention belongs to infusion bottle or bag field of material technology, particularly to one be used for manufacturing infusion bottle or
Bag the self lubricity composite of Easy-folding enclosing cover and the application in medical packaging material thereof.
Background technology
In recent years, the medical large transfusion plastics package industry development of China is rapid, progressively substitutes traditional glass
Packaging, the pattern of infusion solutions packaging also gets more and more simultaneously.Current infusion bottle or bag combination cover generally comprise
Enclosing cover, inner cap and the plug being arranged between exterior and interior cover.This three part is to complete to assemble on cover assembling machine,
Specifically by respective track, inner cap, plug, enclosing cover being respectively delivered to assembles module and complete assembling.
The enclosing cover currently used mainly includes draw-ring type enclosing cover and Easy-folding enclosing cover two kinds.The present inventor is to defeated
On the basis of liquid bottle or bag are studied with draw-ring type enclosing cover material, further Easy-folding enclosing cover material is studied, send out
Now need to solve problems with: during (1) long-distance transport, especially north of china in winter, the handle of Easy-folding enclosing cover
Portion is easily opened naturally by collision；(2) Easy-folding enclosing cover rubs greatly on cover assembling machine, and group lid speed cannot
Promote, affect production efficiency.
The CN102276932A that the present inventor applies for before this discloses outside a kind of infusion bottle or bag draw-ring type
Cover material and preparation method thereof, have employed silicone master batch or the nanoscale polytetrafluoroethylene (PTFE) one or two of 9～25
Plant the lubricating resin as draw-ring type enclosing cover material.The draw-ring type outer cover material that the method obtains has certain table
Face self-lubricating property, but this invention cannot obtain preferably confficient of static friction and the coefficient of kinetic friction.If increased
One or both consumption of silicone master batch or nanoscale polytetrafluoroethylene (PTFE), will increase the mist of composite significantly
Degree, and lubricating resin precipitation.
The patent of invention of CN100404606C discloses a kind of employing acrylic resin (PP) and adds polyethylene
(PE), polyolefin elastomer (POE) and KN resin-made for infusion bottle cap material, appropriate by adding
Polyolefin elastomer (POE) solve acrylic resin fragility is big, toughness is not enough problem, but do not give
The self lubricity of product surface.The most domestic enclosing cover of Easy-folding on the market is mainly prepared by following two raw material:
(1) polypropylene；(2) toughening modifying polypropylene.The Easy-folding enclosing cover character that the former prepares is the most crisp, be weak to
Cold, shock resistance is poor；And Easy-folding outer cap surface frictional force prepared by the latter is greatly, cover assembling machine carries not
Freely, production efficiency is affected.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art with not enough, the primary and foremost purpose of the present invention is to provide a kind of use
In manufacturing infusion bottle or the bag self lubricity composite of Easy-folding enclosing cover.This material has good toughness
And self lubricity, utilize its enclosing cover prepared to have and carry smoothly on the track of cover assembling machine, and
Non-damageable advantage in transportation.
Another object of the present invention is to provide a kind of above-mentioned for manufacturing infusion bottle or bag Easy-folding enclosing cover
The preparation method of self lubricity composite.
