According to the invention, a mask is processed according to glass shapes with different regular shapes and heating requirements; a polyurethane hot melt adhesive with conductive macromolecular particles is sprayed on a flexible PVB (Polyvinyl Butyral) film through the mask; a heating wire is replaced by the transparent conductive macromolecular particles to assure the transparency of a piece of produced demisted and defrosted glass, so that the preparation method has the effect of saving materials relative to coating a conductive layer on the whole film; and under the precondition of assuring the heating uniformity, visual observation effects of people also can be improved, so that the safety of driving is enhanced.
Description
Technical field
The invention belongs to electrically heated glass, relate in particular a kind of glass conductive heating film and preparation method thereof.
Background technology
At present, along with people increase day by day to the demand of glass, anti-fog and antifrost glass is widely used in even aircraft etc. above the vehicles of automobile, train as a kind of shatter proof glass.
Anti-fog and antifrost glass is in the market mostly to adopt subsides conducting film, wired mode to reach heating glass, thereby demist goes out white effect, though these modes can demist go out frost in certain mode, has defect and limitation separately; Nesa coating is existing high electroconductibility, again visible ray is had to good light transmission.Enterprise extensively adopts and on transparent film, scribbles metal particle or oxide semiconductor particulate now, and this mode has increased the cost of conducting film; Wired mode is high to nichrome wire production and glass machining technique requirement, and slightly mistake easily causes glass transparent degree low, affects people's visual effect; Electrically heated glass not only will heat the effect that glass plays demist, defrosting the in the situation that of energising, but also will guarantee the transparency of glass, can not have influence on the operation of navigating mate.
PVB film is a kind of macromolecular material through softening agent plasticizing extrusion molding by polyvinyl butyral resin, its to unorganic glass have good cohesive force, there is transparent, heat-resisting, cold-resistant, moisture-proof, the characteristic such as physical strength height, be on our times, to manufacture the optimum adhesion material that interlayer, shatter proof glass are used; Simultaneously, visible light permeability and visual perviousness that polyethylene oxide gathers the conducting polymer particles such as fourth, diacid glycol ester or polyoxyethylene glycol imines are excellent, demonstrate high conductivity, therefore can be using it as the electro-conductive material in anti-fog and antifrost glass (as shown in progress > > prepared by document < < structural conductive macromolecular nanoparticle).
Summary of the invention
The present invention is directed to the existing disappearance of above-mentioned prior art, main purpose is to offer and a kind ofly can plays heating glass, can make demist go out white glass more attractive in appearance without the conducting film of sight line restraining mass again, can be adapted to higher demist and go out white requirement.
According to the solution of the present invention, a kind of glass conductive heating film is comprised of flexible PVB film and electrically conducting transparent polymer particles, first make one and cover plate, this covers plate and adopts the pure aluminum plate that thickness is 0.5 ~ 1mm, profile is identical with flexible PVB film, on plate, open U-lag covering, U-lag is wide is 2mm ~ 5mm, the distance of adjacent U-lag is 15mm ~ 20mm, the plate of covering after fluting is covered on flexible membrane PVB, by Polyurethane hot melt adhesive heating and melting, then conducting polymer particle is added in the Polyurethane hot melt adhesive of molten state, the Polyurethane hot melt adhesive of hybrid conductive polymer particles being put into agitation vat rotation mixes again, when mixing, rotation answer heated and stirred bucket to guarantee that Polyurethane hot melt adhesive is in molten state, after to be mixed, Polyurethane hot melt adhesive is added to forcing machine, then forcing machine sprays Polyurethane hot melt adhesive to flexible membrane PVB along covering U-lag on plate, the thickness of Polyurethane hot melt adhesive equals to cover plate thickness, draw lead-in wire, after being down to room temperature, stick solidifies, finally remove and cover plate, be electrified the utmost point, the outer temperature regulator that connects.
For conducting polymer particle is evenly distributed in Polyurethane hot melt adhesive, can in Polyurethane hot melt adhesive, add the SiO of Polyurethane hot melt adhesive quality 5%
2powder, correspondingly, the conducting polymer particle that joins Polyurethane hot melt adhesive is controlled at 15 ~ 20% of Polyurethane hot melt adhesive quality, and the time that rotation mixes is 2 ~ 4h; If do not add SiO
2powder, the corresponding conducting polymer particle that joins Polyurethane hot melt adhesive should be controlled at 30 ~ 35% of Polyurethane hot melt adhesive quality, and the time that rotation mixes is 15 ~ 20h.
Described SiO
2powder adopt aminomethyl phenyl hydroxy silicon oil and vinyltriethoxysilane as associated treatment agent process, be specially: SiO
2powder 100 weight parts, aminomethyl phenyl hydroxy silicon oil 1.5 weight parts, vinyltriethoxysilane 1 weight part, measures ball milling, ball milling post-heating to 150 ℃ dry 4 hours by three kinds of raw materials, stand-by after discharging.
Advantage of the present invention is: can process and cover plate according to the glass shape of different regular shapes and demand for heat, adopt electrically conducting transparent polymer particles to replace heater strip more can guarantee that the demist of producing the transparency of white glass, and with respect to spray conductive layer on monoblock film, play the effect of saving material.This invention can also improve people's sight line observing effect under the inhomogeneity prerequisite that has guaranteed heating, has strengthened drive safety.
