Abstract

The invention discloses a kind of preparation method of waterproof microporous barrier, including：(1) it is dehydrated after mixing polyethylene glycol and PTMG, control temperature adds 4,4 ' methyl diphenylene diisocyanates, constant temperature at least 30min at 75 85 DEG C；(2) add Isosorbide-5-Nitrae butanediol as chain extender, add stannous octoate, stir, after temperature reaches 120 DEG C, film forming obtains the waterproof microporous barrier.The hemolysis rate of the polyurethane of present invention synthesis is respectively less than 5%, meets the hemolytic requirement of biomaterial, while the antiplatelet adhesion property of material is also fine.

Description

A kind of preparation method of waterproof microporous barrier
Technical field
The present invention relates to field of material technology, more particularly to a kind of preparation method of waterproof microporous barrier.
Background technology
Waterproof can respiratory refer to that thin polymer film and coating do not allow water droplet to pass through, while but to ensure stream molecule Freely pass through, reach the respirable purpose of waterproof.The clothing of this kind of material production, footgear etc. can both play a part of waterproof, and Avoid sultry, the uncomfortable shortcoming of cold wet grade that traditional adverse circumstances clothing is produced.According to the respirable principle of waterproof not Together, the material can be divided three classes：Pore type, hydrophilic and shape memory type.Pore type is reached by controlling the size in aperture To the respirable purpose of waterproof：Hydrophilic is non-porous film, the main hydrophilic radical by material to the absorption of stream molecule- Diffusion reaches the respirable purpose of waterproof：Shape memory type is reached by controlling the glass transition temperature of polymeric material Identical purpose.Latter two can play fungi-proofing effect for non-porous structure, and same pore type also may be used by controlling the size of micropore Play fungi-proofing effect, therefore application of this kind of functional form material in terms of medical treatment is also increasingly wider, can be used for wound dressing, outer Section's operation dress and protectiveness clothing, medical gloves etc..
The content of the invention
It is an object of the invention to propose a kind of preparation method of waterproof microporous barrier, its water-proof breathable properties is good.
It is that, up to this purpose, the present invention uses following technical scheme：
A kind of preparation method of waterproof microporous barrier, including：
(1) it is dehydrated after mixing polyethylene glycol and PTMG, control temperature adds 4,4 ' hexichol at 75-85 DEG C Dicyclohexylmethane diisocyanate, constant temperature at least 30min；
(2) add BDO as chain extender, add stannous octoate, stir, after temperature reaches 120 DEG C, film forming is obtained To the waterproof microporous barrier.
The present invention uses 4,4 ' methyl diphenylene diisocyanates as hard section, polyethylene glycol and PTMG binary Alcohol has synthesized thermoplastic polyether polyurethane as mixing soft section, and its water-proof breathable properties is good.
The present invention, for the contribution of prior art, is the proposition of new technological process, content as each material and Proportioning, is prior art, and those skilled in the art can be determined with unrestricted choice or by limited number of time experiment, the present invention Repeat no more.
The material obtained to the present invention carries out the test of water contact angle, in showing material after absorbing water, due to depositing for PEG Meander configuration is changed into from sawtooth pattern in, its strand, hydrophilic ehter bond is placed in chain outside, hydrophobicity-CH2-CH2- inner side is placed in, Hydrone easily combines to form weak hydrogen bond with ehter bond, so as to cause polarity to strengthen, hydrophilic increase, it can be seen that introduce PEG effective The hydrophily that improve material.
Water absorption rate test shows that introduction PEG causes that the hydrophilic radical in such polymer molecule increases in material, Yi Yushui Hydrogen bond is formed, so with increases of the PEG containing child in soft section, the water absorbing capacity of material gradually increases.With reference to water contact angle and suction Water rate is tested, and soft section introduces PEG and can be very good to improve the hydrophily of material, contributes to hydrone in material surface and inside Absorption and spread, to improve material can breathable properties be very helpful.
Hemolytic experiment and blood platelet static state adhesion experiment result show that the hemolysis rate of the polyurethane of present invention synthesis is respectively less than 5%, meet the hemolytic requirement of biomaterial, while the antiplatelet adhesion property of material is also fine.
Specific embodiment
Technical scheme is further illustrated below by specific embodiment.
