Description
Technical field
The invention belongs to coloured glass field, is specifically related to low temperature coloured glass yellow colorants and preparation method thereof
And application method.
Background technology
Coloured glass refers to the glass that can be absorbed, reflect, different colours are presented through the light of different wave length, can be used for
Building and ornament materials, high-grade glass product, drinking utensils, tableware, art work etc..Coloured glass has blue, dark brown, grey, green, gold
The color and lusters such as color, there are multiple functions, if effectively absorbing the radiant heat of the sun, produce and " cold room effect, reach and cover thermal center energy
Effect；The sunlight of transmission can be made become soft, avoid dazzle；The ultraviolet of sunshine can be effectively absorbed, prevents indoor article from taking off
Color, rotten, etc..
Coloured glass preparation technology at present, it is to add glass colorant in 1600 DEG C or so of glass-melting furnace directly to make
Take, the temperature of smelting furnace is high, coloring agent component can be made to melt completely, and glass basestocks are full and uniform mixes, obtained color
Glass quality is excellent.With increasingly harsh, its production work of the continuous expansion of coloured glass application field and national energy-saving requirement
Skill is shown to compared with low melting glass gradually to low temperature, small-scale development（1200℃）Molten bath glass colorant
Great demand.At such a temperature, the diffusion rate of colouring agent component is much smaller than 1600 DEG C of molten baths, and original high-temperature colorant can not fit
With, it is therefore necessary to special colorant type of the exploitation suitable for the temperature.
Yellow is the color formed by wavelength between the light of 570-585 nanometers, and red light and green light mixing can produce Huang
Light, give people brisk, full of hope and vigor sensation.For yellow in coloured glass field, blue-colored glass is high-grade drinking utensils, meal
The indispensable important category such as tool, the art work.Chinese invention patent《Coloring agent for UV absorbing yellow float glass》
（02110302.X）Disclose a kind of yellow coloring with iron oxide, manganese oxide, cobalt oxide, vanadium oxide etc. for main coloring components
The preparation method of agent, suitable for the production of yellow float glass.This method has that color development is unstable, diffusion rate is low, heavy metal
The problems such as element pollution, it is significant to develop new low form yellow glass colouring agent.
