Photo-cured resin, hydrophilic lubricating coating and preparation method of photo-cured resin

ActiveCN105732848AExcellent biosafety and compatibilitygood adhesion
The invention discloses a photo-cured resin, a hydrophilic lubricating coating and a preparation method of the photo-cured resin. The photo-cured resin can be prepared by adopting a method of carrying out crosslinking copolymerization on polymerizable diphenyl ketone photo-initiator and a vinyl pyrrolidone monomer under the action of an acrylamide cross-linking agent; a photo-cured hydrophilic lubricating coating can be obtained through compounding the resin. The photo-cured resin is capable of overcoming the disadvantages of residue, volatilization and migration of micro-molecular photo-initiators in coatings, has excellent biological safety and compatibility, and is suitable for the medical field. The hydrophilic lubricating coating has a cross-linking structure, so that the hydrophilic lubricating coating not only has good adhesive force on the surfaces of medical catheters, but also has excellent lubricity when wet, thereby reducing the friction coefficients of the surfaces of the medical catheters, decreasing the harm to the human tissues, and decreasing the adhesion of the macro-molecules in the blood. The hydrophilic lubricating coating is applied to medical catheters in a photo-curing manner; compared with the traditional curing manner, the photo-curing manner has the advantage of greatly shortening the curing time so as to greatly improve the production efficiency.
