Abstract
A polyurethane disperse system comprises polyurethane urea, and the polyurethane urea comprises at least one hydroxyl containing polycarbonate polyols, and is end-capped by a poly epoxybutane and poly epoxypropane copolymer unit. The polyurethane disperse system can improve the slide hydrophilic performance, and the coating composition provided by the invention has the characteristics of high level of blood compatibility. Results show that the coatings are favorable in working, and especially in blood contact. Compared with polymers in the prior art, the material shows a reduced tendency in solidification in blood contact.
Description
Technical field
The present invention relates to dispersion, be specially a kind of polyurethane dispersions.
Background technology
Medicine equipment as the utilization of conduit can be by it being equipped with to hydrophilic surface and greatly improving.The insertion of urine or vessel catheter becomes easier with the fact of changing the hydrophilic surface adsorbed film of water by contacting with blood or urine.This has reduced the friction between catheter surface and vessel wall, thereby makes conduit more easily insert and move.Can also be before inserting to the apparatus water that directly wet, to reduce and rub by forming uniform water film.Result is that associated patient has less pain, and has reduced the risk of vascular damaged.In addition, when conduit is used for contacting with blood, the risk that always exists blood clot to form.In the case, hydrophilic coating is regarded as contributing to antithrombotic coating conventionally.To what produce that this type of surface is applicable to, be in principle from the cruel solution of poly-ammonia of correspondence or the polyurethane coating of the initial manufacture of dispersion.
Summary of the invention
Technical problem solved by the invention is to provide a kind of polyurethane dispersions, to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A polyurethane dispersions, it comprises polyurethane-urea, this polyurethane-urea:
(1) use the copolymer unit end-blocking of polybutylene oxide and poly(propylene oxide);
(2) polycarbonate polyol that comprises at least one hydroxyl.
In the present invention, described polyurethane-urea comprises the unit that derives from least one aliphatic series, alicyclic or aromatic isocyanate.
In the present invention, described coating comprises polyurethane-urea, and this polyurethane-urea is synthesized by following material:
A) mean mol is at least one polycarbonate polyol that 400 grams/mol-6000 grams/mol and hydroxy functionality are 1.5-2.5, or the mixture of this type of polycarbonate polyol;
B) mixture of at least one aliphatic series, alicyclic or aromatic polyisocyanate or this type of polyisocyanates, its amount is every mole of described polycarbonate polyol 1.0-4.0 mole;
C) at least one simple function mixing polyoxyalkylene ether of polyethylene oxide and poly(propylene oxide) or the mixture of this type of polyethers, its mean mol is 500 grams/mol-5000 grams/mol, its amount is every mole of described polycarbonate polyol 0.01-1 mole;
D) at least one aliphatic series or alicyclic diamine or at least one amino alcohol, as the said chain extension agent of people, or the mixture of this compounds, its amount is every mole of described polycarbonate polyol 0.05-3.0 mole.
beneficial effect
The present invention, except improving the wetting ability performance of sliding, is also high-caliber blood compatibility according to the feature of coating composition provided by the invention.As a result, it is also favourable utilizing these coating work, particularly in blood contact.With the polymer phase ratio of prior art, described material demonstrates the trend of solidifying reducing in blood contact.
