Specific embodiment
The present inventor by depth studying extensively, develop for the first time it is a kind of can be used in laboratory can quantitative assessment
The method of coating paint film flow leveling.The method of the present invention is easy to operate, and standard is readily identified, and can accurately quantitative determine coating
The levelability of sample can be widely applied for coating material production field, and further be limited the standard of coating material production, from
And improve the overall quality of coating material production.
Coating levelability
Research thinks that the driving force of levelling is the surface tension of coating, and levelability is coating after applying, and generates the energy of flow
The ability of various surface imperfection shapes is voluntarily sprawled in the drying process and eliminated to power.
Currently, the method in this field for measuring levelability is that testing surface is lain against to glass plate, guide plate is scraped in painting
It is placed on testing surface side, and is parallel to testing surface long side, scraper notch is downward, is open to operator, is placed on against guide plate
Testing surface distal end.Then, the 10mL uniform coating sample for being transferred to operating viscosity is placed in edge in scraper.Guide plate is compressed on the other hand,
Another hand-held scraper is along guide plate from far to closely at the uniform velocity painting is scraped to testing surface proximal end.By the testing surface scraped be horizontally arranged into
Row drying, then the parallel band of observation stream together is to quantity, to make levelling grade.However, in the above-mentioned methods, painting is scraped
Process is needed by manual operation, and is observed by the naked eye and judged levelling grade, therefore is easy by subject's operation error
Limitation, cause the result property of can refer to limited.
Verkholantsev thinks that levelability can be evaluated with Adams formula (formula II), it is assumed here that film brush mark
For attached sine wave shown in Fig. 2:
αt=α0exp[-Cγh3t/(3λ4η)]
α in formula0-- amplitude of wave form when starting；
αt-- by the amplitude of wave form after time t；
C-- constant；
The surface tension of γ -- coating；
H-- is averaged wet-film thickness；
Elapsed time after t-- wet film brushing；
The wavelength of λ -- brush mark；
The viscosity of η -- coating.
The viscosity of coating sample is low it can be seen from formula II, and brush mark wavelength is short, and amplitude of wave form is small, average wet-film thickness
Greatly, sample surfaces tension is high, and the time of levelling is long, can levelling to sample it is advantageous.The wet-film thickness that is wherein averaged is acted as with 3 powers
With the wavelength between brush mark is worked with 4 powers.Surface tension is conducive to greatly levelling, but surface tension cannot be excessively high, otherwise can
Influence wetting and attachment of the coating to base.
Herster thinks, during levelling, coating surface tension drives levelling, and coating viscous force hinders levelling.Levelling
Stress can be calculated by Jackman formula (formula III)
The π of τ=83γhα0/λ
τ in formula -- levelling stress, the meaning of other parameters is the same as formula II.
During coating levelling, γ, λ and h are kept approximately constant, therefore levelling stress reduces with the reduction of amplitude of wave form,
When levelling stress is equal to or less than the yield stress τ of coating0When, the levelling of film will stop.Therefore, by film waveform
Amplitude measures, and can carry out to the levelability of film objective and reliably evaluate.

What form error.Therefore, with 3D roughness contourgraph, the micro-shape of surface of the paint film can be measured, such as shown in attached drawing 3
Surface of the paint film.Therefore, in the methods of the invention, by using the measurement coating paint film waveform vibration of 3D surface coarseness profiling instrument
Width, thus quantitative assessment film levelling.
3D surface coarseness profiling instrument carries out the test of film levelability
Applicant has found under study for action, using the conventional 3D surface roughness profile that be used to measure surface quality of workpieces
