The invention discloses preparation methods of an intelligent dimming PVB (Polyvinyl Butyral) film and intelligent dimming PVB laminated glass. The preparation method of the intelligent dimming PVB film comprises the following steps of: dispersing a dopant-containing vanadium dioxide nanopowder dispersing solution of which a high-temperature phase or low-temperature phase has a phase change function into adhesive PVB resin, stirring to form a PVB sizing agent, and then preparing the PVB film with an intelligent dimming property by adopting a coating or extrusion molding method; and the preparation method of the intelligent dimming PVB laminated glass comprises the following step of: putting the intelligent dimming PVB film prepared by using the preparation method between two layers of glass by adopting a hot-pressing molding process to obtain the intelligent dimming PVB laminated glass. The PVB film with the intelligent dimming property can be molded on glass without any adhesive and extra process and is formed in one step, therefore, the preparation process is greatly simplified, and furthermore the cost of the intelligent glass is reduced; and meanwhile, the stability and service life of an intelligent dimming layer are greatly improved. The laminated glass can be widely applied to building energy conservation, car window heat insulation and other aspects.

Description

The preparation method of a kind of intelligent dimming PVB film and intelligent dimming PVB doubling glass
Technical field:
The present invention relates to the energy-saving building technology field, be specifically related to a kind of intelligent dimming PVB film and intelligent dimming PVB doubling glass.
Background technology:
Polyvinyl butyral acetal (PVB) is under catalyst action at present, through butyraldehyde-n and the PVA aqueous solution carry out condensation reaction and synthetic resins, have transparent, fast light, water-fast, film forming and erosion-resisting characteristics, glass, metal, timber, pottery, leather, fiber and other material there is adhesiveproperties preferably, be the best tackiness agent of glass in the world, so its main application is as the intermediate adhesion thin film layer in laminated safety glass is made.At present, about 89% PVB is used to produce the shatter proof glass of building and automobile industry.
Under the severe day by day background of power supply, energy-saving and cost-reducing is the target of the common struggle of the people of the world.Building energy consumption accounts for 30% of whole society's total energy consumption, and wherein topmost is exactly heating and air-conditioning, accounts for 20%.Go along with sb. to guard him greatly in the parts in four of building, account for whole building and heating and more than 50% of air-conditioning power consumption by the door and window dispersed heat.Western developed country is carried out the research work of Energy Saving Windows from the sixties in 20th century, as heat-reflecting glass, and Low-E glass etc.The energy-conservation of Building Trade in China is mainly reflected on window design and the illuminating energy-saving, and be less to the use of Energy Saving Windows.
Vanadium dioxide is a kind of transition metal oxide with phase-change characteristic.The vanadium dioxide monocrystal material can take place to change mutually at 68 degree, changes cubic metallic state high temperature under into from cryogenic monocline semi-conductor attitude, and the transformation that M phase (low temperature phase) arrives R phase (high temperature phase) promptly takes place.When phase structure changes, the optics of vanadium dioxide material, electricity, physicalies such as magnetics are also undergone mutation.Aspect optics, vanadium dioxide is because the transformation of structure can be by the transformation of cryogenic infrared transparent attitude to pyritous infrared external reflection attitude, thereby reaches the purpose of reflected infrared and sunlight.The phase transition temperature of vanadium dioxide can be regulated by the content of doping agent, spends to 68 degree from-20.Therefore, can realize intelligence adjusting sunlight and ultrared purpose with the film of vanadium dioxide preparation, at energy-saving coating, optical memory material, there is purposes widely aspects such as lasing safety.
The method that preparation commonly used at present contains the vanadium dioxide coating mainly contains magnetron sputtering method, chemical Vapor deposition process, sol-gel method etc., and these methods all exist apparatus expensive, cost height and complex process, and the film forming area is little, is not suitable for limitations such as batch process.Patent CN102399072A, CN102120615A, CN102464354A, CN102336528A has mentioned the method for filming after the hypovanadic oxide powder dispersion, but because the dispersion system of using in these methods does not all have advantages of good caking property on matrix, can only on specific matrix, apply, limit its use range greatly.Still need to apply and to use after one deck is installed glue even be coated on coating on the flexible parent metal, not only increased the complicacy of rete technology, and increased the film cost.
Summary of the invention:
The preparation method who the purpose of this invention is to provide a kind of intelligent dimming PVB film.
Another object of the present invention provides a kind of preparation method of intelligent dimming PVB doubling glass.
The present invention is achieved by the following technical programs:
A kind of intelligent dimming PVB(polyvinyl butyral acetal) preparation method of film, the vanadium dioxide (VO that contains doping agent that R phase (high temperature phase) or M phase (low temperature phase) are had phase transition function 2) the nano-powder dispersion liquid is distributed to has in the close-burning PVB resin, stirs to form the PVB slurry, the method by coating or extrusion moulding prepares the pvb film with intelligent dimming performance then; Described coating refers to apply the PVB slurry that one deck contains vanadium dioxide nano powder on pvb film; Described extrusion moulding is that the PVB slurry that contains vanadium oxide is extruded the intelligent dimming pvb film that the back curtain coating is drawn into different size; Described doping agent is selected from least a in tungsten, molybdenum, niobium, tantalum, zirconium, the fluorine element, and the content of doping agent is VO 2The 0-5% of molar content; The content of vanadium dioxide is 1-100g/L in the described PVB slurry, and more preferably scope is 10-75g/L.
Described VO 2The particle diameter of nano-powder is preferably 20-500nm.
Described VO 2The nano-powder dispersion liquid, VO 2Massfraction in dispersion agent is 0.5-20%, described dispersion agent is an organic solvent, is selected from least a in methyl alcohol, ethanol, Virahol, butanols, benzene,toluene,xylene, methyl acetate, ethyl acetate, propyl acetate, butylacetate, hexyl acetate, acetone, espeleton, ethylene glycol monomethyl ether, ethylene glycol monobutyl ether, acetonitrile, pyridine, methylene dichloride, chlorobenzene, dichlorobenzene, ether or the sherwood oil.
A kind of preparation method of intelligent dimming PVB doubling glass will insert between the layer glass by hot-forming by the intelligent dimming PVB film that preceding method prepares, and form the PVB doubling glass with intelligent dimming performance.
Described glass is simple glass, toughened glass or half tempered glass.
PVB film with intelligent dimming performance of the present invention can take shape on the glass without any need for binding agent and extra technology, once shaped, simplified preparation technology greatly, and then reduced the cost of intelligent glass, simultaneously since the intelligent dimming layer between layer glass, reduced because the oxidation of air and the possibility of artificial destruction make the stability of intelligent dimming layer and life-span improve greatly.This doubling glass can be widely used in aspects such as building energy conservation, vehicle window heat-insulation.
