Description
Technical field
The present invention relates to a kind of float glasses, and in particular to a kind of heat absorption energy-saving glass and preparation method thereof.
Background technique
Sunlight is the reason of causing indoor air temperature to increase.Especially in summer, in order to reduce room temperature, air-conditioning, fan
The energy consumed by equal cooling systems is huge, causes great energy waste.Therefore the glass with heat absorption capacity is for building
It builds, vehicle energy saving is of great significance to.It is well known that sunlight is mainly by visible light, infrared ray and ultraviolet light three
Part forms, and wherein infrared ray proportion in the energy of solar radiation is larger, and about 50%, it is the main portion for needing to obstruct
Point.
Antisolar glass is a kind of plate glass that can absorb a large amount of infrared radiation and the good visible light transmittance of holding.
Ideal antisolar glass is opaque to infrared ray, and does not absorb visible light.But this ideal antisolar glass is very
Made from difficulty, absorption spectrum made of reality will generally absorb the visible light of a part, usually wave in the glass of infrared region
Long range 620~760nm red visible and wave-length coverage 390~455nm violet visible.Antisolar glass is by system
Two classes can be divided by making technique, and one kind is the material coloring antisolar glass of online production, and another kind of is offline or online production is with gold
Belong to the antisolar glass of sull coating or non-coating.Wherein expect that coloring antisolar glass is that one kind is coloured with iron ion to be main
The body-tinted glass of agent, by control ferric iron and ferrous ratio, reaching reduces solar thermal energy, ultraviolet light, infrared ray
The purpose of transmitance.
Absorption of the glass to ultraviolet light can be improved in ferric iron, and absorption of the glass to infrared ray can be improved in ferrous iron, and
Ferrous colorability is about ferric 10 times, can be real by adjusting ferric iron and ferrous content in glass system
The purpose of existing shielding ultraviolet rays and infrared ray, however ferrous iron exists, and seriously affects the transmitance of visible light, finally makes major part
Antisolar glass is lower than 75% to the transmitance of visible light, is not able to satisfy the indoor requirement to natural lighting, increases to a certain extent
Add lighting energy consumption.
The prior art passes through to make to establish certain equilibrium state in melten glass liquid between ferrous oxide and iron oxide
Suitable reducing agent is added and melts under the reducing conditions, iron oxide is promoted to be converted into ferrous oxide.However different reducing agent
Requirement to process conditions is different, reduction effect is different, some reducing agents under the conditions of high-temperature fusion it is unstable be difficult to play hold
Long reducing property, the chemical reduction reaction that some reducing agents carry out in fusing are difficult to meet technique requirement, it is necessary to increase and use
Amount can just be met the requirements, and different reducing agents significant difference in terms of forming bubble and blub, finally make antisolar glass obtained
Performance complies with one's wishes not to the utmost.
The Chinese patent application of 103951186 A of Publication No. CN discloses a kind of batch for producing high ferrous glass
Component is formed based on known soda-lime-silica glass, by adding Fe2O3Reach energy-efficient effect, and passes through addition simple substance
Silicon, carbon dust and SO3, increase Fe in glass finished-product2+Content, improve the energy-efficient performance of glass.But SO3Addition, mentioning
Fe in high glass finished-product2+Content while, on the one hand improve melting furnaces clarifying and homogenizing proparea, the concentration of gas in glass metal,
To improve the difficulty of glass metal clarification and defoaming, the diffusion of minute bubbles internal gas in glass metal is also influenced, is caused small
Bubble is difficult to eliminate generation air blister defect, on the other hand also glass is easy to cause carbon-sulfur coloring occur and influences the light transmission of glass
Rate.
