Include：Vanadium dioxide temperature control film 1, colloid 2, liquid crystal temperature control light modulation film 3；Wherein, the vanadium dioxide temperature control film 1 and the liquid crystal temperature
Controlled dimming film 3 is bonded together by colloid 2.
In above-mentioned technical proposal, the vanadium dioxide temperature control film 1 uses the polyester temperature-control energy-saving film of doped vanadium dioxide.
In above-mentioned technical proposal, the colloid 2 uses acrylic film, and its thickness is 30-50 microns.
In above-mentioned technical proposal, the colloid 2 uses ultraviolet cured adhesive, and its thickness is 5-15 microns.
In above-mentioned technical proposal, the liquid crystal temperature control light modulation film 3 passes through state for light when room temperature is less than 37 degrees Celsius, institute
State the compound temperature-control energy-saving transparent state of film of vanadium dioxide/liquid crystal；The liquid crystal temperature control light modulation film 3 is higher than 37 degrees Celsius in room temperature
When be light-scattering state, the compound temperature-control energy-saving film of the vanadium dioxide/liquid crystal is in frosted state.
The utility model has the advantage of：
Combined temperature control energy-conservation film of the present utility model had both possessed vanadium dioxide energy-conservation film temperature in use higher,
The characteristics of having liquid crystal temperature-control energy-saving film temperature adjustable again, after two kinds of films are laminating, learns from other's strong points to offset one's weaknesses each other, realizes low temperature light
Line is passed through, high-temperature shielding ultraviolet and ultrared effect, thus can according to the ultrared transmitance of external temperature intelligent control,
Reach the effect of intelligent temperature control.And prepared vanadium dioxide/liquid crystal composite energy-saving film has temperature in use scope wider,
Can be used for the fields such as building energy conservation and automobile sun-shading film.
