Than every square metre of China heating and refrigeration energy consumption is about 3 times of developed country, but comfort level can not show a candle to people, for this purpose, country's building section
Energy new standard regulation, new building energy conservation must arrive the year two thousand twenty up to 50%, and the total energy consumption that enable the whole society build reaches
65% general objective.The data shows that Chinese total amount just rises year by year, China's building energy consumption accounts for the 40% of total energy consumption at present,
In by door and window lose energy be 46%, i.e., every year by windowpane be lost about 2.25 hundred million tons of standard coals of energy, be equivalent to
21 pipe of reinforced concrete at Three Gorges Power Station annual electricity generating capacities, so building energy conservation first has to pick up from door and window.And high performance selectively masking material can
So that glass has the function of selectivity through under the premise of can penetrate most of visible light without influencing daylighting, again to spectrum
It can stop infrared light, far red light, ultraviolet light, block heat radiation, to reduce the energy consumption of air-conditioning or heating installation, reach energy conservation
Purpose.
The radiation wave band range that the sun reaches ground is about 200~2500nm, wherein 200~400nm is ultraviolet light,
400~800nm be visible light, 800~2500nm be near infrared ray, and near-infrared can be divided into short wavelength-NIR (800~
1100nm) with long wave near-infrared (1100~2500nm), human eye only has direct perception to visible light, so to reach energy-efficient mesh
, it is necessary to shielding infrared ray and ultraviolet screen as far as possible only allows visible light-transmissive.

Good shielding action；Nanometer LaB6、CeO2In 200nm~400nm (ultraviolet light) and 800nm~1300nm (short wavelength-NIR line)
There is extraordinary shielding action, without the too many visible light of absorption；Nanometer WO3The wavelength being hazardous to the human body 200nm~
400nm, the electromagnetic radiation X-ray between ultraviolet light and gamma-rays have a good shielding action, and simultaneous oxidation tungsten is to long wave, short
Wave near infrared ray has certain shielding action, it is seen that light transmission rate is high；Nano-TiO2、ZnO、CeO2、SiO2With photocatalysis
With self-cleaning dirt-removing functions；Therefore, the present invention can shield all ultraviolet light and near infrared ray and high visible light is saturating
Cross rate.
The waterborne polyurethane resin that the present invention uses PEEK modified contains a ketonic bond in polyurethane resin molecular skeleton
With the repetitive unit of two ehter bonds, PEEK structure has anti alpha, β, γ, X-ray effect, be in all engineering material performance it is comprehensive,
Radiation resistance is best, and therefore, PEEK modified waterborne polyurethane resin can effectively improve the adhesive force, corrosion-resistant of film
Property, heat-resisting quantity, water vapor resistance, resistance to ag(e)ing, humidity resistance, wearability, radiation resistance, antistatic property, from anti-flammability and
