Description
Technical field
The present invention relates to the fireproof high-temperature resistant material, specifically, the present invention relates to a kind of composite fire mould material.
Background technology
Refractory castable (claiming high temperature resistant mould material again) is a kind of granular and powder material of being processed by fire-resistant/high temperature resistant material, and adds a certain amount of wedding agent and moisture is formed jointly.It has higher flowability, and is suitable to the pouring procedure construction, and to need not heating be hardenable unshape refractory.Generally build moulding with the method for pouring into a mould, shaking or making firm by ramming, also can process prefab and use at the scene of using.Refractory castable is the principal item of unshape refractory.
Cement, powdery hydraulicity inorganic coagulation material.Add water and stir the back and become slurry, can in air, harden or in water, better harden, and can materials such as sand, stone securely gluing as a kind of important gelling material, be widely used in engineerings such as civil construction, water conservancy, national defence together.The content of CaO and its rate of set, intensity have very big relation in the cement.
For cement refractory castable, the effect of cement is most important.No matter be for refractory castable moulding, condense, sclerosis, maintenance, drying, intensification, sintering, still for the final performance or the work-ing life of refractory castable, the cement of adding has all been brought into play vital role.According to the difference of CaO content in the refractory castable, can refractory castable be divided into non-cement refractory castable (CaO content＜0.2%), ultra-low cement refractory castable (CaO content 0.2-1.0%), low-cement refractory pouring material (CaO content 1.0-2.5%) and Portland cement fire resistant pouring material (CaO content＞2.5%).
In these several types of mould material, low cement deposit material relies on better comprehensive performance to be widely used.This be because, when content＜1% of CaO, the rate of set of mould material is slack-off, demould time prolongs, dry tenacity reduces, the winter construction performance significantly degenerates, even all non-sclerous through a couple of days; Otherwise, the content of CaO＞2.5%, the flux material of mould material is too much, and high-temperature behavior and erosion-resisting characteristics will worsen like line variation, hot strength, the slagging of retractory degree of depth after burning.
But in the kiln engineering, the local Chang Yin of mould material lining body receives harsh high temperature erosion or high temperature wear and damages in advance, thereby has shortened the life-span of kiln lining.Therefore, the needs exploitation is high temperature resistant, resistance to fouling can better ultra-low cement refractory castable.Be the exploitation ultra-low cement deposit material, will solve that existing ultra-low cement refractory castable setting rate is slow, demould time is long, dry tenacity is low, the problem of winter construction poor performance.
Silicon sol is a kind of novel wedding agent.But silicon sol is still not extensive in the application of unshape refractory.Major cause is: silicon sol combines unshape refractory normal temperature, and sclerosis is very slow down, need could solidify through heating, drying treatment.Solidify if simply add aluminate cement, uncontrollable condensing will take place in silicon sol, so just can not make fine and close lining body through shaping.
Add the cement of silicon sol, very uncontrollable to solid-state transformation from fluidised form, solidify rapidly good flow, the back that is shaped when mould material is shaped, and the sclerosis back obtains good physical and chemical performance, is badly in need of solving this difficult problem.
Summary of the invention
To the deficiency of prior art, the object of the present invention is to provide a kind of have good forming property and curing performance, can obtain the compound ultra-low cement refractory castable of good high temperature resistant, anti-erosion, thermal shock resistance after the curing again.
The present invention be through with corundum, alumina and mullite as filler; The employing silicon sol is that wedding agent, small amount of aluminum acid salt cement are solidifying agent, obtains condense normal, that sclerosis is fast and excellent high temperature resistant, low pore and the superior composite casting material of erosion-resisting characteristics through adding alumina powder, silicon ash and silit.
Said composite fire mould material is meant that cement-silicon sol combines, and forms the cotton-shaped CaO-Al of cloud
2O
3-SiO
2-H
2The combination of O colloidalmaterial.
The present invention realizes through following technical scheme:
A kind of refractory castable is made up of particulate material, matrix material and admixture, and is specifically composed of the following components:
