The powder particle diameter of traditional refractory fibre raw material modifying agent is 50~200 mesh, and the present invention uses 400~600 purposes
Coloring agent powder.Although increasing disintegrating process difficulty, experiments verify that, coloring agent powder used in the present invention can get
The more uniform distribution on refractory fibre, in conjunction with more secured, more uniformly, dyefastness is higher for dyeing.
The selection of melting temperature is from the difference composition of raw material, and in the present specification, inventor is preferred through constantly experiment
2100~2300 DEG C of melting temperatures as padding magnesium-aluminum-zirconium composite fire fibrofelt raw material, particularly preferred temperature are true
The partial size that rule depends on the different compositions of raw material and crushes.

Under industrial nitrogen auxiliary, coloring agent is adhered to spinning solution surface and melts to the outer layer of spinning solution rapidly, at the same time, industry
Nitrogen also plays the role of cooling and solidifying to spinning solution, and the solidification of spinning solution also achieves coloring agent powder in refractory fibre table
The fixation in face, to realize the coloring of magnesium-aluminum-zirconium composite fire fiber surface, this is a most important invention in this specification
Point.After tested, coloring agent powder is evenly distributed on refractory fibre surface.In addition, conventional centrifugal, which gets rid of silk, uses air as cooling
Solid gas, in the present specification using industrial nitrogen be according to reason avoid the oxidation of colorant at high temperature, thus
Improve the color of gained padding refractory fibre product.As for padding magnesium-aluminum-zirconium composite fire fiber dye level then
It is codetermined by the concentration of coloring agent powder in coloring agent itself, industrial nitrogen and the air velocity of industrial nitrogen.
Preferably, the quality proportioning of main material is MgO 60%~85%, Al2O35%~25%, ZrO25%~
10%, Y2O31%~5%, SrO 1%~5%, TiO21%~5%, total amount 100%.
Preferably, the coloring agent is di-iron trioxide, copper oxide, ferroso-ferric oxide, ferrous oxide, cuprous oxide, oxygen
Change one or more of cobalt, vanadic anhydride and chrome green.
The fiber solidifying formative stage of magnesium-aluminum-zirconium composite fire realize absorption of the coloring agent on refractory fibre, fixation and point
It dissipates, so that being made a kind of has dyeing more uniformly, the high magnesium-aluminum-zirconium composite fire fiber of dyefastness is one of the invention
