Description

A kind of Alumina gel film coating and preparation method thereof
Technical field
The present invention relates to film coating technical field, particularly relate to a kind of Alumina gel film coating and preparation method thereof.
Background technology
Inorganic nano-particle can play mechanics in coating to be strengthened or gives the effect of coating New function and be subject to extensively Pay close attention to.The dispersion of nanoparticle is even more important for the realization of its function, special high transparent organic-inorganic hybrid nanocomposite coating Preparation.
Vanadium dioxide has huge application prospect in terms of intelligence heat-insulating and energy-saving coating, but due to its preparation method and work The restriction of skill, and the strong absorption that vanadium dioxide metal phase and quasiconductor are in short wave ranges, vanadium dioxide film is usual There is relatively low optical clear, significantly limit its actual application.Therefore, the anti-reflection of vanadium dioxide film is increasingly becoming research One of focus.
Due to the peculiar property of inorganic nano-particle, it is frequently used to join organic as enhancing phase or functional stuffing In coating, improve coating tradition performance, give coating specific function characteristic.The nanoparticle being presently used for coating mainly has gold Belong to oxide (such as TiCh, Si02, Sn02, ZnO etc.), nano metal powder (such as nanometer A1, Co, Ti, Cr, Nd, Mo etc.) and Nano metal salt (such as CaCO), BaS04) etc..The function of inorganic particulate in hybrid coating to be given full play to, needs the uniform of particle Fine dispersion, the when that particularly the transparency to composite coating having higher requirements；
, due to its manufacturing process, usually there is reunion stronger between particle in commercially available inorganic particle, is difficult to directly application In preparing composite coating.In organic coating field, usually the various physics of integrated application and chemical dispersion techniques, enter nano-powder Row is modified and dispersion, and carries out compound preparing nanocomposite coating with organic resin.Very difficult preparation is provided simultaneously with the visible transparency The composite membrane strong with infrared barrier；
Vanadium dioxide has thermochromic function, reduces phase transition temperature by doping and makes it possess the potentiality of actual application.To the greatest extent Pipe it has been reported the preparation method of a lot of vanadium dioxide and doped vanadium dioxide powder and thin film at present, but actual apart from it Application, still has a segment distance.First, conventional the preparation technology such as apparatus expensive such as magnetron sputtering, vapour deposition, cost is high, relatively Difficulty realizes large area and covers with paint, lacquer, colour wash, etc.;Secondly, traditional preparation method is due to the limitation of itself, the vanadium dioxide of preparation or dioxy The visible region transparency changing vanadium (W) thin film is poor, does not substantially have the possibility of actual application.Although having done much at anti-reflection aspect Attempt, such as doping, coat anti-reflection film, but the raising of the transparency still ratio is relatively limited;Again, the report that oneself has at present is substantially Concentrate on vanadium dioxide or the preparation of vanadium dioxide (W) pure film, and seldom dabble organic coating route to prepare vanadium dioxide heat Cause discoloration coating.4th, the research about hypovanadic oxide powder or the stability of thin film (including composite membrane) is reported very at present Few.Therefore, preparation has the vanadium dioxide film of the relatively high visible district transparency or compound with vanadium dioxide as functional stuffing Film, and investigate its stability, there is important practical significance；
On the other hand, the dispersion of nanoparticle and stabilization technique are more used for the preparation of organic-inorganic nanocomposite materials the sixth of the twelve Earthly Branches, Disperse uniformly reaching it, fully realize its function as implant.Common step is to first pass through physical chemistry dispersion Technology prepares the nano dispersion fluid of inorganic particulate, then dispersion liquid and organic resin is being combined.In organic coating field, first Step often utilizes the scattered method of ball milling (having under dispersant existence condition) that inorganic particle particle is carried out de-agglomerated.At said process In the middle of, the compatibility between the compatibility and nanoparticle and organic resin between nanoparticle and disperse medium may be produced Raw contradiction, if the organic molecule of grafting and resin compatible are the best, during resin solidification is dried, it is possible that receive Being separated between rice corpuscles and organic facies, causes the decline of the nano-composite coating transparency.Therefore, the purpose of the present invention is exactly Prepare the nanoparticle that dispersibility is higher, join in organic coating, play the effect of enhancing.
