Summary of the invention
Yet there is following problem in the coating material in past.
(1) coating material of using as outer wall; for example on buildings wall etc. during coating titanium dioxide; priming paint (primer) resin etc. is necessary; because this bottom paint resin etc. is an organism; titanium dioxide decomposes priming paint; the degradation phenomenas such as wall material that the titanium dioxide that causes peeling off causes, promptly cause (choking) phenomenon of so-called being jammed or powder phenomenon; so be necessary to carry out the surface preparation as the deterioration protection of wall etc. of for example priming paint thickness thickening etc., yet if do the problem of the decomposability that reduction titanium dioxide is arranged on the contrary like this.
(2) in addition, owing to objectionable impurities may not equalization be disperseed in atmosphere, so light-catalyzed reaction is local inhomogeneous generation, so the problem that can not carry out high efficiency light-catalyzed reaction is arranged.
(3) in addition, carry out drying if the photocatalyst fused solution is coated on base material such as wall or coated face, though on wall, form the film of photocatalyst, but the hardness of this film, substantially be 5H under the situation of antifouling coating material in the past, equates substantially with the hardness of people's nail, therefore if the nail tip of choosing scrape, the film damage can occur, perhaps film is peeled off such problem from wall.Change the ratio of components of compounding substances, when obtaining the hardness more than the 5H,, also exist film the problem of crackle to occur if be coated with drying.
(4) and, titanium dioxide if be not subjected to the irradiation of ultraviolet energy, can not be brought into play wetting ability, at night, existence can not be used the problem of having utilized hydrophilic function.
(5) in addition, the coating material of using as inwall in titanium dioxide under the situation of combined silver title complex, titanium dioxide, silver complex, itself is chemically stable material.Therefore, in fused solution, even mixed melting titanium dioxide and silver complex, can chemistry or physical bond yet, in solution separate dispersion state.Therefore, if insufficient stirred solution, titanium dioxide and silver complex just can not uniform mixing, just can only obtain the solution of inhomogeneous admixture.In addition,, place for some time, because inhomogeneous blended state has been got back in the natural convection of solution etc. again even stir mixing.If will not have mixed uniformly solution coat like this to wall, antibacterial effect is reduced,, and consider from the functioning efficiency aspect not only from the action effect aspect, also not preferred such ununiformity wishes to find to make titanium dioxide and the mixed uniformly means of silver complex.
(6) and, as the inwall coating material, during the combined silver title complex, the environmental pollutants molecule that should decompose, can not decompose even irradiates light does not activate yet if do not contact with catalyzer titanium dioxide in titanium dioxide.Environmental pollutants is if be present in and the isolating place of silver complex, and the anti-microbial effect of silver complex, anti-mildew effect can not act on environmental pollutants effectively, can not bring into play the antibacterial ability that silver complex has.Under the situation with titanium dioxide and silver complex simple mixing in past, because not having, any material do not catch the function that keeps environmental pollutants energetically, so environmental pollutants is present in and titanium dioxide and silver-colored isolating position more, the result also has the problem of the decomposition efficiency that can not improve environmental pollutants.
Therefore, the purpose of this invention is to provide antifouling coating material, the coating material of using as outer wall, improve the decomposability of titanium dioxide, can carry out light-catalyzed reaction expeditiously, and after the coating drying, do not crack, by improving the hardness of film, can improve the antifouling coating material of weather resistance, the antimicrobial quilt mould material is provided simultaneously, and the coating material of using as inwall is when mixing titanium dioxide and silver complex, can uniform mixing, improve the antimicrobial quilt mould material of the decomposition efficiency of environmental pollutants thus.
For addressing the above problem, the invention provides coating material, it is characterized in that blending dispersion contains the phosphatic rock composite photocatalyst solution and the polymethoxy polysiloxane solution that contains the polymethoxy polysiloxane of the photocatalyst of the phosphatic rock that has supported porous matter.
In this case, above-mentioned phosphatic rock composite photocatalyst solution, contain useful porous matter phosphatic rock be covered titanium dioxide the compound TiO 2 particles of phosphatic rock and, contain ACRYLIC EMULSION and organic silicon emulsion water-soluble solvent and, pure water, above-mentioned polymethoxy polysiloxane solution preferably contain at least the polymethoxy polysiloxane and, contain ethanol and methanol solvent and, pure water.
In addition,, the invention provides coating material, it is characterized in that making the photocatalyst and the thiosulfate anion that have supported porous matter phosphatic rock to close the silver complex mixed melting in fused solution for addressing the above problem.
And, for addressing the above problem, the invention provides coating material, it is characterized in that the be covered compound titania powder of the phosphatic rock that titanium dioxide constituted and thiosulfate anion of the phosphatic rock with porous matter closed the silver complex mixed melting in the fused solution that is made of ACRYLIC EMULSION and organic silicon emulsion and tensio-active agent and pure water.
Like this, coating material of the present invention, by mixed dissolution photocatalyst titanium dioxide and, the phosphatic rock that constitutes of the calcium phosphate of absorption topsoil material and, hydrophilic resin grease coating material polymethoxy polysiloxane, bring into play the effect that multiplies each other of these materials, it is innoxious and make wall antifouling to make wall etc. go up accompanying objectionable impurities.Simultaneously, can not need the surface preparation during coating mixed solution material on wall etc.In addition, mixed liquid material is coated with operation easily to the sticking power height of paying of wall.In addition,, can make the hardness of the dry film that forms of coating by liquid agent be higher than 5H, improve the physical strength of film itself by adjusting the ratio of solidifying agent contained in the mixed solution material.No matter whether owing to contain have ultraviolet irradiation all bring into play hydrophilic polymethoxy polysiloxane, so even at night also possess hydrophilic property if it should be noted that in the mixed liquid material of the present invention.
In addition, coating material of the present invention, owing to be that photocatalyst and the thiosulfate anion that will support porous matter phosphatic rock closes the silver complex mixed melting in fused solution, in addition, being covered with the phosphatic rock of porous matter, to close silver complex be that melting mixing is containing ACRYLIC EMULSION for the compound titania powder of the phosphatic rock that titanium dioxide constituted and thiosulfate anion, organic silicon emulsion, in the fused solution of tensio-active agent and pure water, so photocatalyst and thiosulfate anion close silver complex, pass through the phosphatic rock physical bond at impartial blended state, reflect impartial admixture like this, can generate the hybrid junctions compound of ratio of mixture equalization.And,, be stable bonding state, so also can keep ratio of mixture certain even do not carry out the stirring of solution in case combination just is not easy to separate.Phosphatic rock, not only work as making photocatalyst and thiosulfate anion close silver complex bonded tackiness agent, and play a role as the pollution substance capture material of catching the mobile assorted bacterium that swims in the air, mould or topsoil material etc., so pollution substance near near photocatalyst or silver complex the time, is broken down into innocuous gas by atmospheric absorption.Promptly, can decompose the decomposition efficiency of raising pollution substance expeditiously.
The simple declaration of accompanying drawing
Fig. 1 has represented to be coated with outer wall of the present invention accelerated test measurement result with the sample of coating material and commercially available weather agent.
Fig. 2 is the figure of expression inwall of the present invention with the pollution substance decomposition efficiency of coating material.
Embodiment
Then, specify embodiments of the present invention.
At first, the embodiment of the coating material that outer wall of the present invention is used describes.
Outer wall coating material of the present invention, blending dispersion normal temperature cured type mineral-type polyorganosiloxane resin solution in compound titanium dioxide fused solution and forming, this compound titanium dioxide fused solution is that the compound titania powder of the phosphatic rock that titanium dioxide the constituted fusion in the solvent that contains pure water and ACRYLIC EMULSION and organic silicon emulsion and tensio-active agent that has been covered of the phosphatic rock with porous matter is constituted, and normal temperature cured type mineral-type polyorganosiloxane resin solution is that the fusion in the solvent that contains ethanol and first alcohol and water of polymethoxy polysiloxane constitutes.
Contained fine titanium dioxide powder end in the compound titania solution of phosphatic rock, it is the powder that on titanium dioxide, has supported the porous matter phosphatic rock of calcium phosphate formation, use such fine titanium dioxide powder end that has supported porous matter phosphatic rock, the photocatalyst that can be used as titanium dioxide plays a role expeditiously, improves the decomposition efficiency of pollution substance tremendously.Promptly, as photocatalyst, titanium dioxide acts on the pollution substance that decompose, and by the photochemical oxidation decomposition reaction, this pollution substance is decomposed, for decomposing pollutant matter, titanium dioxide must carry out physics with pollution substance and contact.Phosphatic rock makes the physics contact more.
Titanium dioxide itself is owing to having the characteristic that absorption keeps pollution substance, so only decompose the accidental material that adheres to.In addition, though the porous matter phosphatic rock of phosphoric acid calcium has the characteristic that can selective adsorption keeps pollution substance, can not decomposing pollutant matter.Therefore, use the material that on titanium dioxide, has supported phosphatic rock.If supported phosphatic rock on titanium dioxide, though expose on the titanium dioxide fine particles surface, phosphatic rock forms convex on its Surface Vertical ground.Because this convex projection structure, even the compound titania solution of phosphatic rock is coated directly onto on the wall, if wall is level and smooth, the exposed portions serve of titanium dioxide does not directly contact with the wall material yet.Therefore, can not prolong as the oxygenizement of the photocatalysis of titanium dioxide and to wall, so just do not need necessary in the past surface preparation.And thus, though pollution substance absorption remains on the phosphatic rock, pollution substance also directly contacts with titanium dioxide.Because pollution substance contacts with titanium dioxide, can bring into play the effect of titanium dioxide as photocatalyst expeditiously, improves the decomposition efficiency of pollution substance tremendously.
Contained ACRYLIC EMULSION and organic silicon emulsion in the compound titania solution of phosphatic rock adds the adaptation and the final wetting ability that generates mixed liquid of wall base material in order to improve final Generation Liquid respectively.Because adaptation that ACRYLIC EMULSION had, be applied on the wall and also can not flow down even will mix liquid, with the wall driving fit, thus just do not need necessity in the past base material is carried out the operation of health, can realize the simplification of painting process.It should be noted that in order to make the best anti-fouling effect of mixed liquid performance, add tensio-active agent and make mixed liquid keep slightly acidic.
Normal temperature cured type mineral-type polyorganosiloxane resin solution as mentioned above, is the solution that the polymethoxy polysiloxane is dissolved gained in the solvent that contains ethanol, methyl alcohol and pure water.Polymethoxy polysiloxane possess hydrophilic property has the function that the physical strength of the dry film that forms of coating that makes by solution improves.Ethanol and methyl alcohol make mixed liquid have volatility, promote the drying of mixed liquid after coating on the wall.
In the compound titania solution of above-mentioned phosphatic rock, mix the polymethoxy polysiloxane solution and be formed with hydrophilic mixed liquid.If should mix liquid and be applied on the wall, drop on rainwater on the wall etc. and do not form the drops body, the moisture film that formation approaches is distributed on whole of the wall substantially equably.Therefore, dissolve in objectionable impurities in the water and also be evenly dispersed in substantially on whole of the wall, disperse absorption to remain on equably and applied in the compound titanium dioxide of phosphatic rock, thereby decompose.That is, partial photocatalysis inequality can not occur, have stable high efficiency photochemical catalysis effect.It should be noted that the ratio of mixture of adjusting the polymethoxy polysiloxane, the hardness that makes the dry film that forms of coating by solution can improve the physical strength of film self in the scope of 6H～10H.Because unguis hominis's hardness be about 5H, promptly use nail to scrape also not have wound, can seek to make the mechanical endurance raising of film so have the film of the above hardness of 6H.If surpass more than the 10H, be coated with dry rear film and crackle occurs.In addition, if hardness level surpasses essential value, the situation that makes the distortion of wall material is arranged.Therefore, except because the limitation of creating conditions makes hardness slightly surpassing more than the 10H, certainly prepare the above solution of hardness 10H as required.
In addition, if the outer wall surface to building is not handled especially, dust that on outer wall, adheres to or greasy dirt etc., when rainy, the rainwater that flows down along outer wall forms the path that flows down of rainwater by accident, because the capillary effect of water, substantially under the accidental path flow that forms, so form dust and the smeary spot apperance that does not flow down along this path, on outer wall, diminish attractive in appearance.Fluent material of the present invention has can resist capillary wetting ability, so when being applied to this fluent material on the wall, rainwater is to fall in the mode that does not form the path, and anti-fouling effect is arranged.
Below specific embodiment is narrated.
