Another object of the present invention provides the coating that contains color ore powder.
In one embodiment of the invention, coating of the present invention comprises the color ore powder that 25wt% is above.
In a further preferred embodiment, coating of the present invention comprises the 10-35wt% tackiness agent, the color ore powder of 25-35wt%, 15-25wt% kaolin, 0.5-3wt% rutile titanium white powder, 4-7wt% talcum powder, 20-35wt% water, other additive of 0-5wt% is as in dispersion agent, suspension agent, sterilant, mould inhibitor, antioxidant, the fire retardant etc. one or more.Wherein tackiness agent can be vinylformic acid and phenylpropyl alcohol (styrene-propene acid) emulsion, preferably uses the vinylformic acid and the benzene emulsion of a small amount of vegetable-protein glue (0.005-0.02wt% is based on vinylformic acid or benzene emulsion) modification.In addition, vegetable-protein glue also can be used as other additive adding.About the preparation of vegetable-protein glue, can consult same applicant's Chinese patent application 98124834 etc.Vegetable-protein glue also can replace with Mierocrystalline cellulose (comprising natural and modified-cellulose such as methylcellulose gum).
Color ore powder of the present invention freshens toner as coating, and its principle is as follows:
One, poly-principle of color ore powder
Moisture with adding 30% in the 1800 order water-ground limestones ground after 45 minutes, left standstill in container, and after 4 hours, water-ground limestone does not condense, and was in half precipitation, half suspended state in emulsion.Under powerful microscope, the contriver finds: though include trace activity substance (silicon) in the water-ground limestone particle, but in the production of coating and application process, do not satisfy the requirements and excite its actives, so the calcium carbonate granule of post precipitation can not reconfigure cohesion, in case be subjected to the effect of external force, will suspend at once.
Under identical envrionment conditions, do same test with 400 purpose color ore powder.Water with adding 30% in the 400 purpose color ore powder ground after 45 minutes, left standstill in container, and after 2 hours, the color ore powder begins layering, precipitation; After 12 hours, precipitation, and combination fully, cohesion, formation has certain degree of hardness, closely knit and whippy integral body; Active substance with color ore powder same hue is suspending in the liquid of container upper part simultaneously, detect according to resource environment test center of institute of Inst. of Geochemistry, Chinese Academy of Sciences, sample is ellipsoid shape, short cylinder, width 20-40 nanometer account for 32%, the 40-60 nanometer account for 49%, the 60-80 nanometer account for 11%, the 80-100 nanometer account for 8%, because its proportion is less than the proportion of water, through secular placement non-agglomerate.Do not precipitate.
Pass through to the observation and the analysis of above-mentioned simultaneous test, draw to draw a conclusion: the interior exterior wall latex paint that with the water-ground limestone is aggregate is after film forming, calcium carbonate granule is embedded in the mantle body of emulsion formation, and particle and gap between particles can only be filled up by emulsion mantle body.Emulsion mantle body is a water-soluble substances, and water molecules is easy to see through it and enters in the film body, can't reach hydrophobic, hates oil, hates dirt, self-cleaning function, and this also is the difficult problem that can't cross over of world's coating industry.After nanotechnology occurs, both at home and abroad some large-scale coating material production enterprises attempt to adopt and add in ultrafine calcium carbonate that nano material is come the method in calcium carbonate filled intergranular space to reach hydrophobic, hates oil, hated dirt, self-cleaning function, but because volatile, the Yi Jutuan of nano material, granularity and calcium carbonate granule do not match and fail.Even success, the price of this coating costliness at home and abroad also all are difficult to promote.Under powerful microscope, observe, the cross section of this coating film body and unfairness, array format is irregular, and still has a large amount of pores.This shows, with lime carbonate be the coating for internal and external wall of aggregate can only reach the function of waterproof and can't thoroughly reach hydrophobic, hate oil, hate dirt, self-cleaning.
The active substance of various dose is contained in color ore powder particulate inside, the granule number of unit space reaches certain value behind the chance water, hydride in the water has activated the active substance in the color ore powder, makes it to the granule surface diffusion, makes radial free diffusion motion in water.The active substance that granule contains is by the mutual polymerization of diffusion, and the agglomerating active substance of polymerization is prohibited admittedly in a certain size the space, constantly to be increased between particle.The space of this typing is assumed to be model, the active substance of poly-group is just long more big more according to intergranular model, the saturated back knot in space is as a whole, and numerous active substances wrap up the color ore powder, just as being embedded in the film body that active substance is agglomerated into.Because during the space of active substance between filling color ore powder particle grain, the water molecules of trace has little time to discharge and is locked in the space between active substance and the color ore powder, makes the state that constitutes the partial vacuum between particle and the active substance.For example, the ore powder solid after the cohesion is taken out from water, cut growth 15cm, wide 5cm, the rectangular parallelepiped of thick 0.5cm is mentioned its two ends in the middle of making unsettled.Under the effect of gravity, the rectangular parallelepiped center is bent downwardly, sink, and displacement is accelerated gradually, and about 30 seconds, rectangular parallelepiped is therefrom separated.This phenomenon from the explanation on the microcosmic is: constituted the partial vacuum state between particle and the active substance, when two particle are subjected to a pair of rightabout reactive force, relative displacement takes place between the particle, after displacement reached certain distance, the progressively intrusion of air separated particle and active substance lentamente.A large amount of particle and active substances are separated on different positions, just show as the bending of rectangular parallelepiped on macroscopic view.In this course, certain zone is stressed big more on the rectangular parallelepiped, and the surface of fracture of this bending area particle and active substance is just big more on microcosmic, and particle and active substance are peeled off fully by the time, and rectangular parallelepiped just ruptures.Active substance has been filled intergranular space, the pore of poly-group rear surface is also sealed by active substance, and the volume that just gathers active substance when rolling into a ball is slightly larger than water molecules, the rete water content is 1% when following, formed void ratio water molecules volume is little in the structure that its arrangement aggregates into, but bigger than volume of air, therefore, the formed structure of active substance that comprises in color ore powder and its body can block water intrusion, but air can freely pass through.Simultaneously part spreads the active substance in the water because the density of unit space does not reach that the active substance polymeric requires can't with aggregation of particles, can only in water, make free diffusion motion, on macroscopic view, show as the emulsion form mixture.
The contriver is fully recognized that the poly-group of color ore powder phenomenon is a kind of embodiment of natural science instinct, and this has brought excitement to the investigator.Because at coating industry, the various countries expert is invariably at the material of seeking to strengthen the rete degree of compactness, with the self-cleaning problem of the hydrophobic of thorough solution coating.For this phenomenon reasonably being applied in the Application and Development of coating, the investigator has carried out research in depth, and invited the researchist of ore expert of Sichuan University and national Ministry of Geology and Mineral Resources, a collection of "dead" color ore is analyzed, determine the constituent content of each color ore, the kind and the unit content of active substance, and the mechanism that the color ore powder is met water precipitation and cohesion is proved and come to a conclusion.
Two, the color ore powder is the membrane formation mechanism of the coating for internal and external wall of aggregate
The color ore powder particles contains active substance, and the proportion of this active substance is more bigger than the proportion of ordinary calcium carbonate, and common emulsion can't suspend the color ore powder particles effectively and all be dispersed in the emulsion.At this situation, the investigator carries out modification with the vegetable-protein glue additive to emulsion, and (vegetable-protein glue is that the investigator is at above-mentioned situation especial manufacture, vegetable-protein glue has superpower seepage force and force of cohesion, with its additive as coating, the huge force of cohesion of volatilization generation along with water molecules, cross over conventional ADHESION OF PAINTS power and seepage force, strengthen the degree of compactness of rete greatly, make it to form the integral body at no interface with surface of wall), the solid content that increases emulsion is to increase the suspending power of emulsion to solid particulate.Under powerful microscope, the researchist has observed suspension and the polymerization process of color ore powder particles in liquid (mixture of emulsion and water): containing in the liquid of 40-50% moisture, emulsion wraps up the color ore powder, spacing by auxiliary agent control color ore powder particles, suppress exciting and polymerization of active substance, the color ore powder particles is floated on a liquid muchly.
With the color ore powder be aggregate coating for internal and external wall be coated with install to surface of wall after, moisture part in the coating is penetrated in the body of wall, another part then evaporate in the air, and the spacing of color ore powder particles is with the infiltration of the volatilization of water molecules and vegetable-protein glue and dwindle gradually.When liquid water content drops to 15% when following, the spacing of color ore powder particles narrows down to the degree that can excite the active substance in the particle, active substance begins to excite and slowly extends out to granule and prolongs, progressively filled intergranular space, accelerated water molecules simultaneously toward the outer evaporation rate of film body.Contain a large amount of ultramicro active particles in water and the emulsion mixed solution, wherein part ultramicro active particle is extruded to film surface and begins permutation and combination, the ultra micro pore of filling film laminar surface.Along with the further volatilization of water molecules, after the density of the active substance of unit space acquired a certain degree, particle begins arrangement, and also polymerization was agglomerating, closely is adsorbed on the surface of rete, makes rete become more closely knit, and glossiness is higher.The dry mantle of emulsion paint has formed neutral closely knit film body owing to containing a large amount of active substances, and the ultramicro active material plays the increased activity effect between rete.When liquid water content drops to 5% when following, active substance is all excited and poly-fully group, the also basic completely solidified of the weighting material in the rete between particle and the particle.When liquid water content drops to 1% when following, the mixture on film body surface (emulsion and active substance) completely solidified film forming, the degree of compactness of film surface is the strongest, it is the highest that glossiness reaches, form the closely knit rete of colour stone powder of no pore, use ultramicroscopic observation, under the effect of force of cohesion that additive vegetable-protein glue produces and seepage force, the film surface planeness is fine and closely woven bright and clean as glass surface, form the integral body at no interface with surface of wall, thereby had hydrophobic, hate oil, hate dirt, self-cleaning excellent function.
The practical value of color ore powder in coating for internal and external wall
Anti-aging, colour-fast:
The material of natural colorful stone flour is compared more closely knit with lime carbonate, and contain active substance, be used for the coating active substance space between nonseptate poly-filler particles takes place, hard, the smooth closely knit rete of final formation, be difficult for being invaded efflorescence, have good ageing resistance by external oxide compound, acidic substance (acid rain) and obnoxious flavour; The natural colorful stone flour belongs to the natural inorganic thing, and ultraviolet radiation is extremely low to its rate of fading.To being that the exterior coating of aggregate is made synchronous weathering test with the exterior coating that contains organic color paste toning with the natural color stone powder, uviolizing is after 200 hours, and mill base begins to fade; Irradiation was above 300 hours, the exterior coating that contains mill base is changed beyond recognition, and be that the exterior coating of aggregate was by uviolizing in 500 hours with the natural colorful stone flour, not having the phenomenon of fading takes place, the data that obtain from national inspection centers show that this is that all mill base coating can't be compared, and proves that fully the natural colorful stone flour is good anti-aging, ultra-violet radiation resisting material both at home and abroad, do the exterior coating that aggregate produces with the natural colorful stone flour, just can thoroughly solve COLOR FASTNESS PROBLEM.This discovery has brought an important breakthrough to coating industry.
The investigator is in the characteristic of anti-aging, the ultra-violet radiation resisting of further investigation natural stone-powder, great discovery is arranged: be rich in active substance in the natural colorful stone flour particle again, make the aggregate of coating for internal and external wall of the natural colorful stone flour, active substance is excited under certain condition, nonseptate poly-group takes place, and produces the material of particle diameter between nano level and sub-meter grade voluntarily.Vegetable-protein glue belongs to the sub-meter grade powder, granularity is near nanoscale, with its additive as modified emulsion, just form the rete of thickness 400-500 micron at coatingsurface, vegetable-protein glue produces superpower seepage force with the infiltration of water molecules, carry active substance and penetrate into matrix inside, in the body of wall pore, form hard skeleton; When thicknesses of layers reaches the 300-400 micron, under the effect of water molecules evaporation, vegetable-protein glue water-swellable will be excited and the nanometer that produces is shifted the film body top layer onto to the material the sub-meter grade by active substance, because vegetable-protein glue has strengthened the viscosity of emulsion, emulsion wraps up these fine materials, make its unlikely volatilization, while is under the contraction of the huge force of cohesion of vegetable-protein glue, these fine materials are aggregated in matrix surface securely, capillary micropore between the secondary filler particles, become void-free integral body after saturated, strengthen the degree of compactness and the flintiness of filming, form the closely knit surperficial dura mater of ultra micro; Along with the evaporation of water molecules, under the effect of the superpower force of cohesion of vegetable-protein glue additive, film body shrinks gradually in addition, and thickness finally reaches about 200 microns.The smooth closely knit surfacecti proteon screen of final formation.Rete has been crossed over common ADHESION OF PAINTS power and seepage force, form one smooth, closely knit, no interface with matrix surface, realize in the world application standard to nano material, the contact angle of water droplet, oil droplet or droplet and matrix surface is near zero degree, broken not hydrophobic of chemical field water solvent, the not lipophobic conventional law of Oil solvent, reach hydrophobic, hate oil, hate dirty excellent function, water molecules does not exist, but air can free flow, fundamentally stop the growing environment of mould, thereby reached the mildew-resistant self-cleaning function.
The contriver has formulated the new formulation for coating material and the technological process of production to the characteristics of used color ore powder and the characteristic of contained active substance.Use through test and batch process repeatedly in 3 years, and the effect behind the architecture construction is carried out tracing observation, occur without any the phenomenon of fading, abrasion resistance and antifouling property are good.Through twice test repeatedly of national coating inspection center, anti-aging test was by uviolizing in 500 hours, and fading extent is the 0-1 level, surmounted the testing standard of country≤2 grade, had thoroughly stopped COLOR FASTNESS PROBLEM.Scrub through 500 times the abrasion resistance aspect, and paint film does not have breakage, head and shoulders above state quota.All test indexs that the color ore powder is made the coating for internal and external wall of aggregate all reach even exceed national standard.Making the coating for internal and external wall of aggregate can compare with the coating of any famous brand name in the world with the color ore powder.
