Abstract
The present invention relates to a kind of TPUE, prepare (a) diisocyanate, (b) PEPA, (c) at least one cahin extension agent, the methylimidazole quinoline trifluoromethayl sulfonic acid ester of (d) 1 ethyl 3, (e) catalyst and (f) optional additive first；By said components (a), (b), (c), (d), (e) and (f) mixing or mutually mixing simultaneously successively, a kind of reactant mixture is obtained, is prepared in 210 250 DEG C of reactions.The present invention not only increases the antistatic property of material by introducing the methylimidazole quinoline trifluoromethayl sulfonic acid ester of 1 ethyl 3 in TPUE raw material, and surprisingly it is good with other component intermiscibilities, the anti-static thermoplastic polyurethane elastomer prepared also shows good mechanical performance, such as tensile strength, ultimate elongation, additionally with excellent abrasion resistance properties.
Description
Technical field
The invention belongs to the technical field of high-molecular compound, it is more particularly related to a kind of thermoplastic poly ammonia
Ester elastomer and preparation method thereof.
Background technology
TPUE is also known as polyurethane termoplastic elastomer (Thermoplastic Polyurethane
Elastomer, abbreviation TPU) be polyurethane elastomer three major types type in one kind, as one kind heating after can plastify, it is molten
The polyurethane elastomer that agent can dissolve, with casting type polyurethane elastomer (CPU) and blending-type polyurethane elastomer (MPU) phase
Compare, TPUE in chemical constitution without or seldom chemical crosslinking, its strand be substantially it is linear,
But there is a certain amount of physical crosslinking.
TPU is as a kind of (AB) n-type block linear polymer, and A is polyester or polyethers of the molecular weight in 1000-6000, is claimed
For long-chain, B is the glycol of the carbons containing 2-12, referred to as short key, and the intersegmental chemical constitution of AB chains is diisocyanate
Combine to form amino-formate bond, is typically connected with methyl diphenylene diisocyanate (pure MDI).
TPU is by lightly crosslinked between intermolecular hydrogen bonding crosslinking or macromolecular chain, with being raised and lowered for temperature, both friendships
Being coupled structure has invertibity.Weaken in molten condition or solution state molecular separating force, and have strong after cooling or solvent volatilization
Molecular separating force link together, recover the performance of original solid.
TPU as a kind of material that elastomer is between rubber and plastics, the characteristics of it is protruded be excellent in abrasion resistance,
Ozone resistance is fabulous, hardness is big, intensity is high, elasticity is good, low temperature resistant, there is good oil resistant, chemical-resistant resistance and environmental resistance.
Usual polyester-type TPU is provided simultaneously with high hardness, modulus and tearing strength and tensile strength, but polyester-type TPU is due to low
Electric conductivity, its antistatic property is poor, and by adding antistatic additive composition mouldability can be caused poor, causes machine-shaping property
Difference.
However, as TPU materials applications field is more and more wider, it is used for the packaging material of electronic unit when it, quick to electrostatic
The part of sense, such as microelectronic component, require the packaging and shell of electrostatic protection, this had both needed good physical property, again
Need good antistatic property.
The content of the invention
In order to solve above-mentioned technical problem present in prior art, it is an object of the invention to provide a kind of thermoplastic poly
Urethane elastomer and preparation method thereof.Described TPUE not only has good physical property, but also
With good antistatic behaviour.
TPUE of the present invention, by making (a) diisocyanate, (b) PEPA and (c)
At least one cahin extension agent reaction is prepared；Wherein described PEPA is the polyesters of binary acid and dihydric alcohol；It is described
First alcohol has the dihydric alcohol of 2-10 carbon atom, and the binary acid has the binary acid of the straight or branched of 4-12 carbon atom.
Wherein, the TPUE, by making (a) diisocyanate, (b) PEPA, (c) at least
A kind of cahin extension agent, (d) 1- ethyl-3-methylimidazoles quinoline trifluoromethayl sulfonic acid ester and (e) catalyst reaction are prepared.
Wherein, the diisocyanate is selected from 4,4- di-2-ethylhexylphosphine oxides (phenyl isocyanate) (MDI), m-xylylene
It is diisocyanate (XDI), phenylene-Isosorbide-5-Nitrae-diisocyanate, 1,5- naphthalene diisocyanates, toluene di-isocyanate(TDI) (TDI), different
Isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI) and dicyclohexyl methyl hydride -4,4- diisocyanate.
Preferably MDI or TDI.
Wherein, the PEPA is preferably adipic acid BDO ester.
Wherein, the cahin extension agent is the glycol with 2-12 carbon atom；For example：Ethylene glycol, diethylene glycol (DEG), propane diols, two
Propane diols, BDO, 1,6- hexylene glycols, 1,3-BDO, 1,5-PD, 1,4-CHDM, neopentyl glycol,
At least one of Benzenediol and Xylene glycol.
Wherein, the catalyst is selected from triethylamine, dimethyl cyclohexyl amine, two stannous octoates, two sad dibutyl tins, February
At least one of dilaurylate, dibutyltin diacetate.
Wherein, the TPUE also includes other available additive.Described additive is selected from face
At least one of material, filler, stabilizer, antioxidant, reinforcing agent, lubricant or plasticizer.
Another aspect of the present invention, further relates to above-mentioned method for preparing thermoplastic polyurethane elastomer, prepares (a) two isocyanide
Acid esters, (b) PEPA, (c) at least one cahin extension agent, (d) 1- ethyl-3-methylimidazole quinoline trifluoromethayl sulfonic acids ester, (e)
Catalyst and (f) optional additive；By said components (a), (b), (c), (d), (e) and (f) successively mixing or mutually simultaneously
Mixing, obtains a kind of reactant mixture, is prepared in 210-250 DEG C of reaction.
The thermoplastic polyurethane prepared by extruder is particle or powder art form, and by conventional injection or is squeezed
Go out processing, so as to obtain injection molding article and extrusion article, example film as required, moulded work etc..For example for the ministry of electronics industry
Packaging material, battery separator, dustproof room articles for use, antistatic clothes and footwear of part etc..
The present invention in TPUE raw material by introducing 1- ethyl-3-methylimidazole quinoline fluoroform sulphurs
Acid esters not only increases the antistatic property of material, and surprisingly it is good with other component intermiscibilities, prepares
Anti-static thermoplastic polyurethane elastomer also show good mechanical performance, such as tensile strength, ultimate elongation, in addition
Also there are excellent abrasion resistance properties.
Embodiment
Technical scheme is further elaborated below with reference to specific embodiment, but they are not limitation
Protection scope of the present invention.
