Abstract
The present invention discloses an environment protection type water-thinned nanometer coating which comprises the following weight ratio of components: 20 to 80 of a film forming material, 0.1 to 10 of a nanometer material, 0.01 to 10 of a surface coupling agent, 10 to 70 of a filling agent, 0.1 to 10 of an additive agent and 10 to 50 of a solvent, wherein the nanometer material is one or more than one of silicon oxide, aluminum oxide, silicon nitride, carbon, acetylene black and polyaniline. The present invention largely increases the performances of aging resistance, ultraviolet radiation prevention, leakage prevention, scouring resistance, etc. so as to enhance the level of the coating and prolong the service life of a coating layer. Particularly, after the surface coupling agent is added in the formula, the adhesive power of the formed coating layer and a base is largely increased.
Description
The present invention relates to a kind of environment protection type water-thinned nanometer paint.
Traditional coating all is to be the oil paint of main film forming material by natural oil plant or resin and synthesising macromolecule copolymer.Oil paint becomes that film coating has chemical resistant properties, water tolerance, tough and tensile, wear-resisting, the advantage such as tint retention is good and sticking power is good of filming.And that maximum shortcoming is the solvent or the part material that contain in the coating is toxic.In production process and coating drying process, these toxic ingredients can evaporate and cause environmental pollution, harmful HUMAN HEALTH.
The appearance of water-borne coatings has solved the problem of solvent contamination.Therefore, water-borne coatings is commonly referred to as environmental protection coating material or green coating.Water-borne coatings is meant that main film forming component can water-soluble (is solvent or thinner with water) maybe can be dispersed in the coating of (is dispersion medium with water) in the water.With water is solvent or dispersion medium, and nothing is smelt tasteless, safety non-toxic, and production technique is simple, and cost is lower, reduces environmental pollution.But, at present general water-borne coatings compare with oil paint have poor storage stability, coating drying temperature height, fine and close inadequately, the shortcoming such as sticking power is not strong of filming.The existence of these shortcomings has limited the widespread use of water-borne coatings.
Be worth should be mentioned that building coating, particularly exterior coating need possess extraordinary performance.Because exterior coating will be exposed to the elements, frost and snow is freezing, burning sun mal-condition such as be exposed to the sun.Temperature changes significantly, can cause expanding with heat and contract with cold of filming.Solar radiation wherein has the intensive ultraviolet radiation, and this will cause the degraded of filming.Therefore, the coating that is used for exterior wall must have preferably ultra-violet radiation resisting, ageing-resistant, antiseep, easily scrub and performances such as washability.Yet the present coating that uses difficulty satisfies these requirements.Exterior coating also should have decorative effect.Along with growth in the living standard, top-grade building and luxurious decoration are more and more, thereby also more and more higher to the requirement of coating appearance, and this just needs the more coating appearance of high-performance.
The purpose of this invention is to provide a kind of coating uvioresistant, the very superior environment protection type water-thinned nanometer paint of wash-resistant property.
The present invention takes following measures in order to achieve the above object:
The components by weight of environment protection type water-thinned nanometer paint is as follows:
Film forming material 20～80
Nano material 0.1～10
Surface coupling agent 0.01～10
Weighting agent 10～70
Additive 0.1～10
Solvent 10～50
Advantage of the present invention: performances such as owing to add nanometer materials in coating, it is ageing-resistant for resulting coating, antiseep, washability all are greatly improved, thereby have improved the class of coating, prolong the work-ing life of filming.After adding surperficial coupling agent especially in prescription, the coating of formation and the sticking power of substrate improve greatly.It is emphasized that water-borne coatings through such modification, the characteristic after its film forming can meet or exceed the performance after the common oil paint film forming.Various coating products outward appearances after nano-material modified seem fuller, even, the bright and clean exquisiteness of filming, and sense of touch is good, and good waterproof performance improves greatly with the cohesive force of base material.Especially be apparent that coating uvioresistant, wash-resistant property after the modification are very superior.
Below in conjunction with embodiment the present invention is elaborated.
The nano material that the present invention proposes is meant that a class granularity is that 0.1～100 nanometer (10～50 nanometer the best), bulk specific gravity are 0.05～0.5g/cm
3(0.1～0.2g/cm
3The best) inorganic or organic fine material.Comprising silicon oxide, silicon nitride, carbon, aluminum oxide, acetylene black, polyaniline etc.These nano materials can be made by various method.Experiment showed, that the film performance after the adding nano material can be greatly improved.Major cause is because little, the light specific gravity of these nano-grain degree can cover coatingsurface preferably and fill the space that forms owing to solvent evaporates when the coating film forming, makes coatingsurface finer and close and smooth.Such surface energy is controlled the water molecules infiltration preferably.The nano material of these molecule degree has superior wear-resisting, resistance to ultraviolet(ray) radiation energy, and the dry rear section of coating is formed on coatingsurface and just can demonstrates fully these effects.Because smooth surface, that color seems is more bright-coloured, it is long to protect the look time.On the other hand, a part is contacted with substrate by the nano material of main film forming matter parcel, has increased the contact surface of coating and substrate, makes the bonding force of filming with substrate strengthen greatly.
According to the GB/T9755-1995 regulation, when reaching 1000 times, the abrasion resistance of exterior coating just reaches country-level standard.By figure one as can be known, after the adding nano material, the abrasion resistance of the coating after its film forming significantly improves in formulation for coating material.When content reached 3%, its washing fastness increased substantially.Surpass at 5% o'clock and almost reach optimum value.Because general nano material is not dissolved in water, only disperse or suspend in water, therefore, too high nano material content can cause difficulties in dispersion, thereby can influence the quality and the performance of coating.Wherein wash-resistant property descends when the nano material too high amount on the contrary.
Described surperficial coupling agent can be serial coupling agents such as silane coupling agent and titanate coupling agent.Silane coupling agent can be to contain in amino, vinyl, epoxy group(ing) or the methacryloxy one or more.Contain two kinds of different in kinds, the different functional group of effect in the molecule of this class surface coupling agent, a hydrophilic in use end combines with substrate, and a hydrophobic end combines with coating, thereby improves the cohesiveness of two kinds of diverse storerooms of character.The wetted area of these surperficial coupling agents is 300～500m
2/ g, therefore, the addition in formulation for coating material can not be too high.General interpolation weight ratio is 0.01-10.Film forming material is one or more in pure-acrylic emulsion, vinylformic acid, alkyd, phenolic aldehyde, the Resins, epoxy.
Add the formed coating of nano material and can be used for coating for internal and external wall, priming paint, protective system, coatings for furniture, floor coating, decorative paint.
The formulation for coating material using method through nano-material modified that the present invention proposes is as follows:
1, cleaning substrate; 2, check the repairing substrate; 3, scrape at the end; 4, polishing; 5, brush rare masking liquid; 6, brush first pass coating is waited to do; 7, second time coating of brush.
Repeat 3～7 programs 2～4 times for external wall construction; The interior wall construction repeats 3～7 programs 1～2 time.Not yellowing of coating after the shaping, wear-resisting, not efflorescence, gloss retention height, good weatherability.
