Description
Technical field
This utility model relates to coating film on glass technical field, particularly a kind of off-line Lycoperdon polymorphum Vitt sunlight controlling coated glass.
Background technology
At present, the production of smoked glass is mainly by introducing coloring components or utilizing float glass process in forming at glass basis
On-line coating mode realizes.Float glass process smoked glass has certain decoration functions and energy-saving effect due to it, by extensively
For building curtain wall, glass door and window and vehicle glass industry.
Chinese patent application CN101462826A discloses Fe2O3、CoO、Se、Er2O3Lycoperdon polymorphum Vitt glass is prepared as coloring agent
Glass, its transmitance is between 62%-67%, and surface reflectivity is less than 6.5%.In order to reinforcing glass is to ultraviolet and ultrared
Absorb, glass ingredient adds the ferrum of a large amount of proportion.Consequently, it is possible to glass can present blueness or green and transmitance is low
Feature, its application is limited.Otherwise, reducing the introducing of ferrum, glass is difficult to again reach preferable energy-saving effect, does not meets modern architecture
Energy-saving and cost-reducing theory.
The coloring agent component that mass colouring introduces is many, and ratio is difficult to control to, and manufacturing cycle is long, and efficiency is low.In such as
State patent application CN101300201A, its colorant assortment introduced reaches 12 kinds more than, and preparation section includes being dried, adding
Heat, anneal, many loaded down with trivial details processes such as cooling, batch production technique is difficult to simplify.
On-line coating refers to the method directly carrying out plated film in former production process of float glass process, and its plated film mode is high-temperature hot
Solve spraying film forming.When the spraying coating process that patent CN101003419A is reported needs the temperature of strict control glass surface, atomization
Pressure, the flow of spraying and the distance of spraying.Its technique is complex, and cost is high, and involved smoked glass is saturating
Rate of crossing is low, reflectance is high, it is difficult to popularization and application.But, the off-line mode of production for smoked glass but rarely has report.
