a hydrophilic coating special for a polyurethane medical catheter comprises 5-8% of hydrophilic lubricant, 1-3% of polyfunctional acrylate cross-linking agent, 3-5% of reactive diluent, 0.1-0.8% of photoinitiator and 83-90% of diluent, wherein the hydrophilic lubricant is polyvinylpyrrolidone, and the molecular content is 10-100 ten thousand.
Preferably, the multifunctional acrylate crosslinking agent is one or more of a difunctional crosslinking agent and a trifunctional crosslinking agent.
Preferably, the multifunctional acrylate crosslinking agent is one or more of ethylene glycol dimethacrylate, 1, 6-hexanediol diacrylate and ethoxylated trimethylolpropane triacrylate.
Preferably, the reactive diluent is one or more of 4-hydroxybutyl acrylate, hydroxypropyl methacrylate, hydroxyethyl methacrylate, hydroxypropyl acrylate and hydroxyethyl acrylate.
Preferably, the photoinitiator is one or more of 2-hydroxy-4' - (2-hydroxyethoxy) -2-methyl propiophenone, 1-hydroxycyclohexyl phenyl ketone and benzophenone.
Preferably, the diluent is one or more of water, ethanol, isopropanol and N-methylpyrrolidone.
A manufacturing method of a hydrophilic coating special for a polyurethane medical catheter comprises the following steps:
s1, weighing 5-8% of hydrophilic lubricating matter, 1-3% of multifunctional acrylate cross-linking agent, 3-5% of reactive diluent, 0.1-0.8% of photoinitiator and 83-90% of diluent according to a proportion, pouring the mixture into a beaker, and stirring the mixture uniformly by using a glass rod in a light-tight environment;
s2, pouring the prepared hydrophilic coating solution into an opaque PE solution pipe, immersing the TPU catheter into the coating solution, and soaking for 10-60 s;
s3, pulling out the TPU catheter soaked in the S2, airing for 5-10min, removing redundant solution on the surface, and irradiating for 2-10min by using a 365nm wavelength LED ultraviolet light source;
s4, washing the manufactured hydrophilic coating catheter with a solution containing 0.1% sodium dodecyl benzene sulfonate for 10 minutes by ultrasonic waves, removing unreacted substances on the surface, washing the catheter with purified water, and airing the catheter at room temperature or drying the catheter for 30 minutes at 60 ℃.
Compared with the prior art, the invention has the beneficial effects that:
1. by utilizing the characteristic that-NH in a TPU carbamate unit is easy to dehydrogenize to form an active reaction point, a cross-linking agent is introduced into the surface, and the other end of the cross-linking agent is connected with polyvinylpyrrolidone (PVP) hydrophilic lubricating molecules, namely PVP-cross-linking agent-PVP are sequentially and alternately connected, so that linear PVP forms cross-linked mesh PVP. Because the PVP is fixed on the surface of the TPU through a chemical bond, the PVP is not easy to fall off in the using process;
2. the PVP molecule main chain side group has a large amount of lactam groups, and can form a large amount of hydrogen bonds with water to form hydrates, so that each molecule oleophylic main chain (lubricating property source) of the PVP is separated and expanded to form gel, namely, the lubricating hydrogel is formed on the surface of the catheter, and therefore, the friction force can be effectively reduced in the sliding process of the coated catheter in a human body;
3. the preparation method of the hydrophilic coating is simple, and only all materials are added and uniformly stirred, so that the monomer residues which do not participate in the reaction in the synthesis are prevented from causing harm to people.
