Abstract
The invention relates to a corundum refractory coating mixture, particularly a corundum light-weight refractory coating mixture. The corundum refractory coating mixture comprises the following components in parts by weight: 30-40 parts of 3-1mm mullite aggregate, 5-15 parts of 1-0 mm aluminum oxide hollow sphere, 10-20 parts of 0.5-0mm aluminum oxide hollow sphere, 11-21 parts of mullite powder, 4-6 parts of modified Faku soil, 5-7 parts of aluminate cement, 1-3 parts of mullite 1-5-mu m whisker, 1-3 parts of titanium nitride 1-5-mu m whisker and 3-5 parts of additive, wherein an alumina sol which accounts for 10-18 wt% of all the components above is additionally added. The mullite refractory coating mixture has the advantages of favorable coatability, favorable sintering property and short curing time, and can be quickly put into baking and use. After being subjected to high-heat treatment, the coating mixture can be sintered together with the furnace lining, has the characteristics of high strength, favorable thermal shock resistance, low cracking tendency and favorable repair effect, and can effectively prolong the service life of the high-temperature kiln.
Description
The application is the divisional application of Application No. 201510356748.X.
Technical field
The present invention relates to a kind of corundum fireproof coating, a kind of corundum light-weight refractory coating.
Background technology
High temperature kiln furnace lining is commonly used alumina hollow ball material and is built working lining by laying bricks or stones, reaches the most high temperature resistant but also insulation, with
Time can realize again heat resistanceheat resistant and peel off, but its expensive disposable and maintenance change put into the biggest.It is resistance to that alumina hollow ball belongs to lightweight
Fire material, its intensity is not so good as compact refractory material, and the most in use, alumina hollow ball refractory lining is often by external blow such as
The product burnt on kiln car or kiln car clashes into and ftractures, falls block, causes kiln heat radiation aggravation to affect kiln sintering effect.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides one to smear conveniently, and agglutinating property is good, and curing time is short, can be fast
Speed puts into baking and the fire-resistant coating used, and this material outstanding feature is exactly that application property is good, smears and facilitates agglutinating property good, and maintenance
Time is short, can be rapidly roasted and use.At high temperature, this coating can be together with old lining sintering, and bond strength is high,
Difficult drop-off.
The present invention solves that the technical scheme that above-mentioned technical problem is used is: a kind of corundum fireproof coating, it is special
Levy and be that it includes the component of following parts by weight: 3-1mm mullite aggregate 30-40 part, 1-0mm alumina hollow ball 5-15
Part, 0.5-0mm alumina hollow ball 10-20 part, mullite powder 11-21 part, modified Faku County soil 4-6 part, aluminate cement 5-7
Part, mullite 1-5 μm whisker 1-3 part, titanium nitride 1-5 μm whisker 1-3 part, additive 3-5 part, additional account for above-mentioned gross weight 10-
The Alumina gel of 18%；Additive is magnesium sulfate calcium potassium powder, silicon powder and carbonic acid zirconium powder, and its weight ratio is 1:1:1, Alumina gel close
Degree is 4.5 for 1.1g/ml, pH.
In above-mentioned dispensing, described Alumina gel such as can be replaced at the Ludox of weight.
The aluminum content of described aluminate cement is more than 50%.
Described modified Faku County soil first step is that after 700 DEG C of insulations 10 hours, acquisition product 1 is the most by weight Faku County's soil
Than 50:1 uniform to product 1 and polyvinyl alcohol, it is modified Faku County soil.
Beneficial effect: one corundum fireproof coating of the present invention, has and has good workability, and easy to apply, agglutinating property is good, supports
Time of protecting is short, can be rapidly roasted and use.After high-temperature heat treatment, this coating can together with old lining sintering, and
Intensity height, good thermal shock, the most easy to crack, repair efficiency are good, be greatly improved the service life of high temperature kiln, through once repairing
After protecting, service life improves more than 30%.
