Description
Technical field
The present invention relates to the solvent wood coatings field in finishing material, specifically disclose a kind of solvent-borne type general can back dissolving delustring slurry, and its preparation method and application.
Background technology
For solvent wood coatings, be divided into Gao Guang, half light and dumb light paint by the height of gloss after formation paint film, and in actual applications, half light, dumb light series products, because its gloss is soft, be more easily esthetically acceptable to the consumers and obtain widespread use.From microcosmic angle object analysis top coat surface luster, be closely related with the degree of roughness of the coating coating surface after drying and forming-film.Coating will form fine uneven surface then needs to possess two conditions: one be have in wet film that a large amount of particle diameter is suitable for, refractive index and the close duller particle of resin dry film, two is the volumetric shrinkages in dried coating film process.Therefore, in reduction coating gloss, adding matting agent is the most frequently used and important scheme of a class.
The flatting silica used in delustring slurry of the present invention is the silicon-dioxide that vapor phase process is produced, aerosil particle diameter is very little, surface is many meso-hole structures, there is huge specific surface area, surface energy is large, and chemical purity is high, with its superior reinforcing, thickening property and thixotropy, show unique characteristics in numerous subject and field, have the effect that normal dull powder is not replaced.Also just because of these advantages of aerosil, in its application, higher requirement is had to dispersing shear power.In the normal production technique of paint vehicle, flatting silica adds at pre-mix stage, like this by the Strong shear power that pre-mix stage adopts, reaches the abundant dispersion of flatting silica.
But require high product for some gloss ranges, often need to regulate gloss in finished product modulation process, usual mode is exactly directly add flatting silica.But this mode directly adding flatting silica, often there are some inevitable problems: due to the porous of aerosil own, surface energy macrostructure characteristic, wetting and dispersing just needs sufficient time and shearing resistance originally, and be about to the material becoming finished product, viscosity often can not be so high as the material viscosity in premix, therefore increase the wetting of flatting silica by extending churning time and improving shearing rate and disperse to be conventional processing mode, but not only need like this to increase manpower and materials, and the solvent evaporates again caused in whipping process likely affects the final Indexs measure of finished product, even application performance is had a negative impact.
If flatting silica is beforehand with form slurry, so because flatting silica has obtained abundant wetting and dispersing, and the liquid slurry of the good fluidity be made into, can directly add when using in coating material production, agitation as appropriate can be dispersed.But, just as described above, flatting silica particle surface porous, the special construction that specific surface is huge, is being made into require it is very special in slurry process, dispersing auxiliary is not only needed to coordinate resin, carry out coated to delustring powder particles in dispersion process, also need to infiltrate in flatting silica particle surface space, extend there through, reach complete wetting, the delustring slurry product of good stability, easily dispersion could be obtained.But there is a phenomenon in such slurry, exactly once delustring slurry dry and hard, cannot as common mill base dry and hard rear with matching dissolvent soak after can dissolve again, namely the mode of " back dissolving " processes, but exist with larger soft particle aggregation state all the time, former fineness cannot be returned to, after finally causing adding in paint vehicle, not only have problems on extinction effect, priorly after paint film film forming, form particle, affect paint film appearance.
Just because of above-mentioned reason, before more than ten years, when delustring slurry making and be used as the scheme of improving production efficiency by industry during suggestion of extension, just because dry and hard delustring slurry cannot back dissolving cause complaining in the actual test of each factory, this project is finally made once to become " industry incurable disease ".So, promote the delustring slurry way of man-haur efficiency, also almost all stagnate.
