Description
Technical field
This utility model belongs to energy-saving building technology field, particularly to a kind of temperature control sun shading and energy-saving film being applicable to hot-summer and cold-winter area.
Background technology
At present, in order to improve the daylighting effect of indoor, building uses glass in a large number, but its heat transfer coefficient of the glass currently used and shading coefficient are all fixed values, it does not reaches and allows sunlight penetrate indoor winter to penetrate indoor this effect less summer, i.e. do not have movable sunshade function more.
In order to stop sun in summer light to indoor irradiation.People take installation external sunshade system, point fixed external shading device and movable external sunshade, and now widely used is movable external sunshade, including outdoor BAIYE, outdoor roller shutter with crank arm or swing arm sunshade.This is to intercept solar radiant heat and sunray by the mode of physics to protect entrance indoor by building external, needs summer to put down during sunshade, does not allow sunlight enter indoor, then pull on winter, allows sunlight enter indoor, and energy-saving effect is obvious.Its shortcoming is: affect outside vertical surface of building；Maintenance, cleaning difficulty big；Service life is the longest.
Sunshade film is exactly a thin film kept the sun off specially or overcoat.
Sunshade film may be used for the various glass panes of automobile, building and showroom to shield daylight, it is also possible to prevents the generation of the second accident caused because of glass broken in accident.According to this Sunshade film, it is by surface protecting layer, plastic film substrate, and hologram etching layer, metal deposition layer, Pressure sensitive adhesion layer and adherent layer are composited in sequence.The most above-mentioned Sunshade film has a basic function, the most excellent visible ray and ultraviolet screener speed, and it demonstrates also have anti-fog function and attractive appearance based on holographic effect simultaneously.
Above-mentioned common Sunshade film belongs to fixed shading, and its shading coefficient is a definite value.It is characterized in that low cost, construction are simple, but energy-saving effect is poor.
Application No. 200810033032.6, the patent of entitled " a kind of intelligent heat preserving thermal isolation film and manufacture method thereof " discloses a kind of energy-saving film, and it is the phase transformation intelligent nano powder body doped vanadium dioxide V using and having rutile-type crystal structure1-XMXO2(0 ＜ X ＜ 0.06), being dispersed in can be in filmogen, and preparation has the intelligent heat-insulating film of phase transition function.Its phase transition temperature is adjustable at 1O C～70 C, has higher infrared transmittivity and relatively low reflectance, excellent thermal insulation performance when temperature is relatively low；There is relatively low infrared transmittivity and higher reflectance, good heat-insulation effect when temperature is higher.
Though this intelligent heat preserving thermal isolation film has movable sunshade function, but it has following weak point: conciliation rate is the lowest, and energy-saving effect does not reaches requirement.Being 60% with light transmittance, as a example by phase transition temperature is the intelligent heat preserving thermal isolation film of 35 C, under low temperature state, shading coefficient is 0.55, and under the condition of high temperature, shading coefficient is 0.45.
Jiangsu Province belongs to area cold in winter and hot in summer, building energy conservation 65% standard to be reached, according to the sunshade requirement of door glass in DGJ32/J157-2013 " the outer window system application technology code of residential architecture standardization " and " residential architecture standardization exterior window system atlas " be: winter and sky shading coefficient in spring and autumn
>=0.6, summer shading coefficient≤0.25, it is seen that above-mentioned intelligent heat preserving thermal isolation film does not reaches requirement.
Application No. 201510318902.4, the patent application of entitled " a kind of photothermal response type intelligent power saving composite membrane " is proposed a kind of color-changing membrane, and this composite membrane is the glass laminating film being formed by stacking by photoresponse film and thermal response film.Its shortcoming is also that the change of shading coefficient does not reaches requirement, can only be clipped between two sheet glass and make doubling photo chromic glass, and can not be used alone.
The change of above-mentioned two intelligent color-changing thin film shading coefficient does not reaches the reason of requirement: optically variable films is uniformly to be incorporated in plastic film substrate by off-color material, make optically variable films, owing to off-color material incorporation is restricted, so the variable color limited extent of the optically variable films made, the change of the shading coefficient of thin film is caused not reach requirement.
Utility model content
