Abstract
The invention discloses a kind of PVB or EVA films of thermochromism, and heat is become coloured particles and is added in PVB or EVA film, laminated glass is made as using the prior art and equipment, without changing existing processing technology.When being irradiated by sunlight, the film in laminated glass reflects sunlight while heated discoloration, plays the effect of shading reflection, and when dark can restore automatically transparent, adjusts without artificial, belongs to " intelligent glass "；Without additionally installing the cover from sun such as curtain, or installation electrode application voltage, manpower and material resources are saved；Maintenance free maintenance of the present invention, physical and chemical performance are stablized, and good weatherability, the service life is long, save the cost, really realize sunshade automation.
Description
Technical field
The present invention relates to film technologies field, a kind of specific PVB or EVA film of thermochromism.
Background technique
Laminated glass is widely used in daily life, especially building and automotive field.Routine building or automobile
Laminated glass two disadvantages can be generated in sunlit situation: one, light-proofness is poor, light through laminated glass it is direct
Irradiation, being shining into eye has dazzling sense of discomfort, be radiated on TV or computerized image generate it is reflective, cause fogging image influence make
With；When automobile in use, the light irradiation driver penetrated, improves driving dangerousness coefficient, so as to cause Exploration on Train Operation Safety；
Usually solve the problems, such as this method be using the shelter with sunshade function, such as curtain, tarpaulin, or give glass coloration, a side
On the other hand face higher cost needs manual operation, inconvenient to use.Two, since sunray has heat radiation, indoor or vapour
Vehicle commander's phase can be improved temperature by light irradiation, not only need the cooling systems such as fan, air-conditioning so as to cause energy consumption and increased costs,
Especially when vehicle interior temperature is higher, because the atomization of oil gas leads to the generation of vehicle spontaneous combustion, the person or property is made to incur loss.At present
There are a kind of method that heat-sensitive material layer production stickup property film is plated by magnetron sputtering, but its complex manufacturing technology, and pastes
Shi Yiqi packet, degumming cause to fall off on glass, and weather resistance is poor.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, provides a kind of PVB or EVA glue of thermochromism
Piece, the technical solution adopted is that: it is 0.1%-10% with thermochromism energy that weight ratio is added in PVB or EVA resin powder
Particle, particle and PVB or EVA resin powder are stirred, so that particle is evenly distributed in PVB or EVA resin powder, use is existing
The mixture is extruded into thermo-color film by extruding technology, is closed piece with glass and is fabricated to laminated glass.
Preferably, the particle is Cu2+ or Ni2+ complex.
Preferably, the particle is vanadate, tungstates and other metal acid-salts and oxide.
Preferably, the particle be the organic polymer system to match with PVB or EVA bulk material physical chemistry and
Liquid crystal.
Further, the appearance shape of the particle can be spherical or other shapes.
Further, the physical and chemical state of the particle can be monocrystalline, polycrystalline, amorphous, indefinite form, glassy state, liquid
State or micel.
Further, the thermo-color film with a thickness of 0.1mm-2.25mm.
Further, the color of the thermo-color film and light transmittance conversion reaction time < 10 second
The working principle of the invention:
Particle of the present invention due to wherein joined thermo-color, when sunlight irradiation when laminated glass film in particle because
The irradiation of sunlight is heated, and particle is caused to change colour, and becomes dark-coloured from transparent, the color of glass automatically from light transmittance 70% to
9%, when dark, restores transparent.Light especially infrared ray impinges upon the scattering that will form between multiple particle on particle simultaneously,
Part will be absorbed, and play the role of barrier infrared ray, i.e. solar irradiation, infrared ray rejection rate from 10% to 70%, therefore not
The effect of shading is only played, the absorption of heat radiation is more reduced.
The beneficial effects of the present invention are: thermo-color is added in PVB or EVA film the present invention, using the prior art and
Equipment making laminated glass, without changing existing processing technology.When being irradiated by sunlight, the film in laminated glass is heated
Sunlight is reflected while discoloration, plays the effect of shading reflection, when dark can restore automatically transparent, adjust without artificial
Section, belongs to " intelligent glass "；Without additionally installing the cover from sun such as curtain, or installation electrode application voltage, manpower and material resources are saved；
Maintenance free maintenance of the present invention, physical and chemical performance are stablized, and good weatherability, the service life is long, save the cost, really realize that sunshade is automatic
Change.
