Description
Technical field
This utility model relates to a kind of safe cladding glass for libraries of the universities.
Background technology
College and university library undertakes college and the important task of scientific research service, meets colleges and universities teachers and students and society
Reader's demand to various information such as economic information, scientific research information, business informations.In Modern University Library Buildings, pursue
The Glass Design of large area daylighting becomes trend.Glass lighting is preferable, and good visual effect has shown that Modern College Libraries is built
The individual character built.Low radiation coated glass (Low-E glass) can significantly reduce while not significantly reducing visible light transmissivity
The indoor and outdoor heat exchange produced due to heat radiation.Low radiation coated glass receives state with the energy-saving and environmental protection performance of its excellence
Inside and outside common concern, is used widely in China university library building engineering.Although but glass curtain wall shows
The individual character of modern architecture, also brings along all secret worries.Particularly the when of summer, indoor/outdoor temperature-difference is big, and glass is particularly easy to certainly
Quick-fried.Winter, season in summer two are taking place frequently season of cladding glass explosion, and main cause is that central air-conditioning temperature is long in many library buildings
The phase too high or too low hidden danger brought.Library generation glass self-explosion happens occasionally, hard to guard against.Libraries of the universities' flow of the people
Greatly, glass self-explosion uphangs skyborne " bomb " just as one, makes each passerby on tenterhooks.The glass of fragmentation after glass explosion
Fragment splashes and drops, and brings potential safety hazard and maintenance cost to libraries of the universities.How on the premise of ensureing light transmittance,
Stopping glass self-explosion is current urgent problem.
Utility model content
For solving the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of safety for libraries of the universities
Cladding glass, reduces the self-destruction rate of glass, the heat insulation and heat-insulating property of reinforcing glass, improves glass weatherability.
For reaching above-mentioned purpose, the technical solution of the utility model is:
A kind of safe cladding glass for libraries of the universities, including organic glass substrate, above lucite substrate
Priming coat, Low emissivity thermal insulation layer, protection face coating are set；Lucite substrate protection face coating is provided below；Lucite
Substrate material is Merlon, and priming coat is polyurethane film, and Low emissivity thermal insulation layer is indium zinc oxide (IZO) thin layer, protection
Finishing coat includes polyurethane film, the organosilicon film arranged from the inside to the outside.
Described each film plating layer thickness is: in priming coat polyurethane film be 0.5-1 μm, IZO thin film be 100-500nm, anti-
During in mask coating, polyurethane film is 0.5-1 μm, protection face coating, organosilicon film is 2-5 μm.In described IZO thin film
The weight/mass percentage composition of In2O3 is 10-13%, and surplus is ZnO.
The beneficial effects of the utility model are as follows:
Simple glass is frangible, toughness is low, and main component is silicon dioxide.Lucite substrate material of the present utility model
Selecting Merlon, Merlon has the feature such as high transparent, lightweight, high tenacity, and more traditional glass material has more
High impact resistance, overcomes the defect of glass self-explosion.Use amorphous state IZO thin film as Low emissivity thermal insulation layer, plating can be made
Film lucite has higher visible light transmissivity and the isolation thermal-radiating ability of infrared band.Inorganic conductive thin film is with organic
There is thermal coefficient of expansion and stress state difference between glass substrate, in use Low emissivity thermal insulation layer is easy to crack and film
Layer adhesion failure, increases polyurethane film between Low emissivity thermal insulation layer and lucite and solves this technical barrier.Organic
In silicon coating, Si-O-Si cross-links in rigidity network structure, and protection face coating has good hardness and wearability, improves poly-carbon
The wearability of acid esters substrate and dependability.Safe cladding glass of the present utility model has lightweight, visible light transmissivity
High and low radiance is good, weatherability strong, overcomes " self-destruction " defect of traditional glass, so that safety curtain of the present utility model
Wall glass has the highest practicality in people intensive buildings such as libraries of the universities.
