Description
Technical field
The present invention relates to technical field of polymer materials, more particularly to a kind of wine bottle stopper and its preparation process.
Background technology
Bottle stopper is that object overflows or the tool of diverging in a kind of volumetric flasks various in order to prevent, and is used for the bottle stopper shape of red wine
Formula is varied, but basic structure and function are all roughly the same, be all bottle stopper is stoppered play the role of in bottleneck it is closed.
Currently, mostly using the corks plug structure such as oak, complex manufacturing technology, cost is higher, while easy ting produce bottle stopper
Taste does not air-dry when making as having yellow spotting on oak bark or cork forms crack because dry, can produce
The smell of the various not smelling good such as raw rotten, smelly water and tar, to influence the quality of red wine, meanwhile, cork itself
Molecule may constantly enter in red wine with the increase of holding time, be greatly reduced the quality of red wine.
In the prior art, have and use TPE compositions manufacture wine bottle stopper to replace traditional cork, in the fabrication process
Mostly use AC foaming agents, and traditional AC foaming agents, it generates ammonia using reaction and generates abscess, AC foaming agents are difficult in TPE
Be uniformly mixed, thus generate cell density and abscess aperture be difficult to control and smell wine bottle stopper that is larger, thus producing
The inhomogenous stabilization of structure, after filling in bottle, leakproofness and stability are poor.
Invention content
The object of the present invention is to provide a kind of wine bottle stopper and its preparation processes, it is advantageous that, the abscess of wine bottle stopper
Uniformly, without smell, it is good that leakproofness and stability after bottle are filled in.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of wine bottle stopper, the wine bottle stopper are made of TPE compositions, and the TPE compositions include following mass fraction

PMMA plays template action, and nano-Ag particles is made to be embedded between macromolecular chain, to play the work of stable nano-Ag particles
With.
Nano-Ag particles surface can be aoxidized and release free silver ion, due to the small-size effect of nano particle
And skin effect, with the reduction of particle size, the surface atom number of nano silver and the ratio of its interior atoms number rapidly increase,
Thus the rate of release of anion significantly improves, and nano-Ag particles are for tens of kinds of Escherichia coli, gonococcus, chlamydia trachomatis etc.
Pathogenic microorganisms has strong inhibition and killing effect, thus the wine bottle stopper containing nano-Ag particles, can effectively protect wine
Red wine in bottle is prevented by external bacterial invasion.
Nano-Ag particles sheet is in the nano-Ag particles on the surfaces TPE, one layer is formd between TPE and mold as spherical shape
Thin lubricant layer, thus play the role of lubricant, be conducive to the injection molding of wine bottle stopper.
Foaming agent with nucleocapsid structure first can uniformly be mixed in TPE, then by increasing temperature, will
The case melts of nucleocapsid make kernel release generate gas, to form microcellular structure, and the micropore knot formed in TPE
Structure is evenly distributed in wine bottle stopper.
PC is distributed in the outermost layer of entire wine bottle stopper, and PC forms IPN, PC and SEBS with SEBS powder, PP particles, PMMA

Reaction foaming.Contain PMMA in itself in TPE simultaneously, thus it is stronger with the compatibility of foaming agent, be conducive to foaming agent and uniformly mix
It closes in TPE, to improve the uniformity coefficient of distribution of cells.
Preferably, using nano carbon particle as kernel in the nucleocapsid of the foaming agent.
By using above-mentioned technical proposal, nano carbon particle after oxidation, generates carbon dioxide, to be produced in TPE
Raw abscess.Carbon dioxide is in the supercritical state, higher in the solubility of TPE, and after injection molding machine is added, pressure reduces, thus
Solubility of the carbon dioxide in TPE reduces, and extra carbon dioxide is simultaneously precipitated out of TPE, during being molded cooling just
Abscess is gradually formed.Carbon dioxide itself is without penetrating odor, thus the wine bottle stopper produced does not have peculiar smell, and dioxy
It is strong to change carbon stability, physical-chemical reaction, molding abscess uniform pore diameter does not occur with other components in TPE.
Preferably, the model SEBS powder -1651 of the SEBS powder.
By using above-mentioned technical proposal, SEBS powder -1651 has good drawing force, elastic force, thus as base material
The hardness that wine bottle stopper can preferably be adjusted, improves the toughness of wine bottle stopper；There is good plasticity simultaneously, be convenient for red wine bottle
The injection molding of plug.
