A kind of diagnosis coating material for glass slide and preparation method thereof
Technical field
The present invention relates to diagnose coating material for glass slide and preparation method thereof, it is specifically related to a kind ofly have the coated material of super-hydrophobic effect and be printed on slide glass, as biological, medical diagnosis analysis.
Background technology
Diagnosis slide glass is widely used in cytodiagnosis, pathology experiment, HPV detection etc., and its profile as shown in Figure 1.Visible, test agent drops in hole, and around coating has super-hydrophobic effect, thereby it is spherical that test agent is formed, and avoids the effect of reagent crossed contamination.Therefore, diagnosis slide glass coated material should have ultra-hydrophobicity, and the contact angle of coating and water should be greater than 150 °, should have good sticking power with slide glass substrate glass, the characteristics such as resistance to each alanysis solvent for use simultaneously.
Large quantity research shows, super-hydrophobic character and surperficial microtexture and lower surface can have very large associated.Super hydrophobic surface has the surface property of a lot of uniquenesses, such as: hydrophobicity, didirtresistance, automatically cleaning etc.Therefore, it has broad application prospects in life and production field.But manually preparing super hydrophobic surface is not to be easy to so.The technology of preparing now super hydrophobic surface exists many deficiencies such as the high and complex process of cost.
Chinese patent [CN200910217946.2] discloses a kind of method that adopts laser ablation and has manufactured super hydrophobic surface.First it is the laser multiple-beam interference system of building, and the then curable or degradable material of spin coating in substrate solidifies curable materials or made degradation material degraded by laser interference lithography, after developing, obtains micro structure array; Then in microstructure, carry out the modification of low-surface-energy material, and then in substrate, obtain the biomimetic colour super-hydrophobic coating that utilizes multi-beam interference photoetching technology to prepare.But this method more complicated is not easy to operate, and cost is higher.
Chinese patent [CN201010164798.5] a kind of polymer matrix composite with super hydrophobic surface and preparation method thereof of openly knowing clearly.Concrete method is: first pre-treatment is carried out in the surface of this matrix material body; Then by resin system brushing its surface and strike off; Be sprayed on resin system surface with metallic oxide nano powder again; Finally be heating and curing, and be placed in the similar solution such as stearic acid ethanolic soln and carry out self-assembly.Same also more complicated of this method, is not easy to operation.Similar patent also comprises Chinese patent [CN200710119670.5], Chinese patent [CN200710065079.6].
Chinese patent [CN200710070728.1] discloses a kind of preparation method of transparent hydrophobic coating.Adopt sol-gel method to carry out film at substrate material surface, and self-assembled modified with coatingsurface being carried out containing the material of hydrophobic chain, and gained contact angle on surface of coating is greater than 150 °.Sol-gel method mainly changes nano inorganic particle by organic precursor into through chemical reaction, but colloidal sol section storage time (being only that several minutes was to several hours).Therefore, this method is unfavorable for large-scale production.
Chinese patent [CN200810061480.7] the invention discloses a kind of preparation method of epoxy resin super-hydrophobic coat.It is characterized in that comprising the steps: the preparation of (1) coating colloidal sol, silicon-dioxide powdery is dissolved in solvent, add silane coupling agent, heated and stirred reaction, adds epoxide resin coating material, hydrophobizing agent, and stirring reaction, makes coating colloidal sol; (2) substrate material surface film, uses the method that lifts film, spin coating, curtain coating film or spraying that the colloidal sol making in step (1) is evenly applied in to substrate surface, set aside for use under room temperature after proposing; (3) process that is heating and curing, puts into baking oven by the base material of film in step (2), and the heating of rising temperature makes epoxy resin cure crosslinked, obtains epoxy resin super-hydrophobic coat after taking-up.Adopt sol-gel method to need low solid content, otherwise can cause that solid separates out.Therefore the super-hydrophobic coating material viscosity that prepared by this method is lower, only can adopt the method that lifts film, spin coating, curtain coating film or spraying to form coating; And for the coating with patterns such as circular holes, adopting silk screen printing more, it requires coated material viscosity to be greater than 10PaS.For this reason, the method that this patent proposes not can be applicable to diagnose slide glass yet.
Meanwhile, comprehensive client both at home and abroad mainly comprises the performance index of diagnosis slide glass coating: 1) can stand enzyme and microwave treatment; 2) can stand long-time storage; 3) HF of massfraction 1% soaks 15 seconds coating performances without impact; 4) HC1 of massfraction 5% soaks 30 minutes performances without impact; 5) more than reaching 5B with substrate glass sticking power.
The present invention, in meeting above-mentioned requirements, has the features such as simple, the with low cost and excellent performance of technique.In addition, the super-hydrophobic coat that the present invention makes, containing poisonous composition, is not suitable for diagnosing slide glass.Inquire about domestic and international patent and have no relevant report.
Summary of the invention
Goal of the invention: the present invention is the super-hydrophobic coating material that preparation is applicable to diagnose slide surface.Meeting outside properties requirement, there is the feature that technique is simple, effect is remarkable and with low cost simultaneously.
