A kind of shaver lubricious strip, is at least made up of elastomer and polyrotaxane, the polyrotaxane by 100 parts by weight line
The end-blocking macromolecular of property polymer, the ring molecule of 200-500 parts by weight and 1-15 parts by weight is prepared, the ring molecule
For cyclodextrin, the linear polymer is the one or more in PEG, PPG, PCL, PVA, PMMA, PEI and PB, the end-blocking
Macromolecular is blocked in the both ends of linear polymer, and the mass ratio of the elastomer and polyrotaxane is 1：0.1-1.
[polyrotaxane]
One or more ring molecule and one or more of linear molecules（As axle）Pass through the weak phase of non-covalent bond
Interaction forms Inclusion Complexes.Linear molecule both ends are blocked group end capping system and form rotaxane or polyrotaxane, if polymer
Both ends do not block, and ring molecule can be with freely in or out polymer chain, just referred to as pseudopolyrotaxane.
The polyrotaxane of the present invention includes cyclodextrin, linear polymer, end-blocking macromolecular.The linear polymer is to wear string-like
Connect by the cyclodextrin bag, the end-blocking macromolecular configuration prevents the cyclodextrin in two ends of the linear polymer
Depart from.Structure is as shown in Figure 1.
(cyclodextrin)
Cyclodextrin（Abbreviation CD）It is amylose under the cyclodextrin glycosyltransferase effect as caused by bacillus
A series of general name of cyclic oligosaccharides of generation, usually contains 6 ~ 12 D- glucopyranose units.
Cyclodextrin is a kind of classical cyclic oligosaccharide, has the hole of molecule compatibility.Cyclodextrin is passed through by starch
Simply enzymatic is obtained, and cyclodextrin is mainly formed by connecting by several D-Glucose units by Isosorbide-5-Nitrae-glycosidic bond.α, β and γ
Cyclodextrin is the cyclic oligosaccharide for having 6,7 and 8 glucose units to be formed by connecting respectively, is a kind of relatively common big ring point
Son.The diameter for being shaped as primary hydroxyl one end of cyclodextrin is less than secondary hydroxyl one end truncated cone.Outer due to cyclodextrin is with a lot
Hydroxyl is so that so that Polarity comparision is big outside hole, and the internal presence for not having hydroxyl make it that inside is non-polar cavity, by
Had the quality that in cyclodextrin, inclusion compound can be formed with lyophobic dust.
Hydrophilic on the outside of cyclodextrin cavity, inner side is hydrophobic, and locally has chirality.The cavity of cyclodextrin can accommodate a variety of
Inorganic molecules and organic molecule and form inclusion compound, because the unique amphipathic structure of cyclodextrin can be used as main body
Molecule carries out Subjective and Objective assembling with many hydrophobic guest small molecules by hydrophobic effect.Suitable guest molecule can be one
Individual, two or more cyclodextrin wear to form catenne, rotaxane, pseudopolyrotaxane, polyrotaxane and pipeline etc. no as beading
Same assembly.
Because cyclodextrin has larger molecule cavity, price relatively cheap and non-toxic and preferable bio-compatible
Property, so that the utilization rate in Macromolecular self-assembly is significantly larger than crown ether, Cucurbituril and several macrocycle molecules of calixarenes.
(end-blocking)
End-blocking is exactly that a group reacts with end group.If the assembly formed to cyclodextrin and polymer chain in the present invention
Assembly that is smaller without end-blocking or capping reagent and can not blocking to obtain is referred to as pseudopolyrotaxane.Capping reagent must be one
The larger molecule of a little volumes.

Amine；When cyclodextrin is beta-schardinger dextrin, linear polymer is one kind in PPG, PB, and end-blocking macromolecular is cyclodextrin aldehyde, triphenyl
One kind in derivative, fluorescamine and fluorescein isocyanate, poly- terminal methyl multicondensed ethylene glycol methacrylate (PPEGMA)；
When the cyclodextrin is gamma-cyclodextrin, linear polymer is one kind in PEG, PCL, PVA, PMMA, blocks the preferred first of macromolecular
Base hydroxy-ethyl acrylate (HEMA).
Preferably PPG, PEG of the invention.PPG and PEG contains substantial amounts of oh group, there is water-soluble and lubricity well
Energy.
(PPG)
The PPG of the present invention includes linear PPG, and functional group includes but is not limited to amino.The PPG of the present invention can be but not
It is confined to following structural formula：
Wherein R1、R2For alkyl, ethers.
PPG 2000 ~ 8000 have it is splendid lubricate, anti-bubble, the heat-resisting resistance to performance such as freeze.
The PPG of present invention molecular weight may be, but not limited to, 1000 to 30000, preferably 2000 to 8000.
The larger PPG of volume can be larger with cavity beta-schardinger dextrin be self-assembly of stable inclusion, can not but penetrate
The alpha-cyclodextrin cavity of small volume.So the present invention and the preferred beta-schardinger dextrin of cyclodextrin of PPG self assemblies, end-blocking macromolecular are excellent
Select cyclodextrin aldehyde.
The synthetic method of the polyrotaxane：A kind of polyrotaxane based on beta-schardinger dextrin, PPG is modified into structure above
Then the PPG of terminal amino group forms pseudopolyrotaxane with beta-schardinger dextrin host-guest inclusion again, finally blocked with cyclodextrin aldehyde
Successfully obtain polyrotaxane.
(PEG)
PEG is polyethylene glycol, and polyethylene glycol is non-toxic polymer substance, and soluble good, lubricity is good.
The PEG of the present invention includes linear PEG, and functional group includes but is not limited to carboxyl.The PPG of the present invention can be but not
It is confined to following structural formula：
, wherein R1、R2For alkyl.
According to number-average molecular weight magnitude classification, including PEG200, PEG400, PEG600, PEG800, PEG1000,
PEG1500、PEG2000、PEG3000、PEG4000、PEG6000、PEG8000、PEG10000、PEG20000、PEG30000、
PEG100000 etc..
The PEG of present invention molecular weight may be, but not limited to, 1000 to 30000, preferably 2000 to 8000.
Alpha-cyclodextrin can form stable inclusion with PEG, and beta-schardinger dextrin can not be self-assembled into stable include with PEG
Thing.So the present invention and the preferred alpha-cyclodextrin of cyclodextrin of PEG self assemblies, block the preferred amantadine of macromolecular.
The synthetic method of the polyrotaxane：A kind of polyrotaxane based on a- cyclodextrin, PEG is modified into such as above-mentioned structure end
Then the PEG of carboxylated forms pseudopolyrotaxane with a- cyclodextrin host-guest inclusion again, finally with amantadine block successfully
Obtain polyrotaxane.This synthetic method has the advantages that cost is low, method is simple and yield is high.
(number-average molecular weight)
Polymer is identical by chemical composition and homologous mixture that the degree of polymerization does not wait forms, i.e., by molecular chain length not
Same high polymer mixing composition.Generally use average molecular weight characterization bulk of molecule.By molecule amount statistical average, then claim
For number-average molecular weight, symbol is (Mn).
[elastomer]
Elastomer refers to the material of the resilient after external force is removed, but flexible material not necessarily bullet
Property body.Simply deformation is notable under weak stress for elastomer, can be promptly restored to after stress relaxation close to original state and size
High polymer material.One kind in elastomer preferred SEBS, SBS, TPEE, EVA of the present invention.
(SEBS)
SEBS is using polystyrene as end segment, and the ethylene-butene copolymer for being hydrogenated with to obtain using polybutadiene is middle bullet
The linear tri-block copolymer of property block.SEBS is free of unsaturated double-bond, therefore has good stability and resistance to ag(e)ing.
(SBS)
SEBS is SBS.
