Description

High-temperature wearable mud
Technical field
The invention belongs to technical field of refractory materials, and in particular to a kind of high-temperature wearable mud.
Background technology
The furnace wall of high temperature kiln is formed by the brick system of fire resisting, during furnace wall builds system, is needed between adjacent refractory brick Bonded using mud, existing mud has that the holding time is short, hardening is fast, bad adhesion, and workability is poor to be difficult construction Etc. defect.So it is easy for leaving hidden danger of quality, has influence on the furnace wall intensity of high temperature kiln.
The content of the invention
The present invention in order to solve weak point of the prior art there is provided a kind of holding time length, caking property it is strong, with good The high-temperature wearable mud of good workability.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that:High-temperature wearable mud, matter is pressed by following raw material Measure number proportions, Al2O3The high grade bauxite fine powder that content is not less than 80% accounts for 55~60 parts, and high-quality Guangxi white clay accounts for 35~40 Part, 5~10 parts of plasticizer, preservative agent accounts for 1.2~1.5 parts, 20~25 parts of bonding agent, is stirred after above-mentioned raw materials precise through machinery Mix, it is in discharging after good mobility to stir at normal temperatures after 5-7min, packed using the double braid bag containing plastic inner lining, Every net weight 25kg.
The mesh number of described alumina fine powder is 320 mesh.
Described bonding agent uses proportion for 1.45~1.55 phosphate dihydrogen aluminum solutions.
Plasticizer uses bentonite, and preservative agent uses oxalic acid.
Using above-mentioned technical proposal, the alumina homogenization material used in dispensing is principal ingredients, with preferable hot strength; It is best in quality that Guangxi white clay (Guangxi dimension sieve white clay ball clay) is that China finds at present, quality most pure soft flame-proof clay, Guangxi white clay has distinctive physical property:Plasticity is good, good fluidity, associativity are good, quality is very pure.Aluminium dihydrogen phosphate feature: At normal temperatures with refractory aggregate, form high-adhesive-strength within constant temperature 4-24 hours between 90-110 °C after the mixing such as curing agent, pass through Just there is high anti-folding, resistance to compression, hydration resistance after 350-500 °C of drying, soak or boil in water and also do not feel like jelly.Swelling Soil helps to strengthen plasticity.Oxalic acid can suppress phosphoric acid as preservative agent and be chemically reacted with the component in material, extend finished product Storage life, improve material service behaviour.
In summary, the present invention in bonding agent is made using phosphate dihydrogen aluminum solution, can preserve at normal temperatures to 180 days with On, there is preferable workability at service temperatures with preferable adhesion strength, during construction, it is ensured that the entirety of masonry is strong Degree.
