Description
Technical field
The invention belongs to chemical field, more particularly to a kind of high-temperature agglomerant.
Background technology
High-temperature agglomerant is called high-temperature adhesives, high temperature adhesives, high temperature adhesive.For water white transparency or yellowish
Thick liquid, it is soluble in water, in faintly acid, without sodium ion.It is especially suitable suitable for being bonded under the conditions of 300 DEG C of high temperature above
Build by laying bricks or stones or repair for High-temp. kiln.The bonding of such as ceramics, various High-temp. kilns, heat-treatment furnace are built by laying bricks or stones and repaired, stove wheel
The gunning refractory repaiied, and paste aluminosilicate refractory fiber etc..Its highest is resistant to 1500 DEG C of temperature, and the short time is resistant to 1800 DEG C even more
It is high.Especially on High-temp. kiln is built by laying bricks or stones or repaired, the stove built by laying bricks or stones with the clay that refractory material is tuned into has antidetonation, anti-stripping
Fall, the features such as resistance to suddenly cold and hot, high temperature resistant airflow scouring, brick and brick are firmly combined with, do not fall brick, do not run away.Due to without sodium from
Son, when pasting aluminosilicate refractory fiber, mullite powdered crystalline can be prevented, and construction and maintenance is convenient, it can save energy 30%~
50%；For building stove or repairing stove by laying bricks or stones, 1~3 times of furnace service life can be extended, reduce factory and repair stove expense and idle cost.
But the high-temperature agglomerant cost used at present is higher, it is impossible to well adapts to the needs in market.
The content of the invention
The cheap and good adhesive effect high-temperature agglomerant it is an object of the invention to provide a kind of cost.
A kind of high-temperature agglomerant, the percentage by weight of its component are：Bentonite 5%~8%, silicon sol solution 38%~42%,
Fluorine polysilicates 20%~25%, schmigel 6~10%, water 20%~25%；Each component sum is 100%；
Use said components prepare the preparation process of high-temperature agglomerant for：First each component is got ready by required usage ratio；Then
Bentonite, silicon sol solution, fluorine polysilicates, schmigel and water are mixed evenly, are heated under conditions of 60~70 DEG C
4 hours are stood, 30~35 DEG C is then cooled to and cures 3 hours, both obtain high-temperature agglomerant.
Further, the percentage by weight of the high-temperature agglomerant is：Bentonite 6%, silicon sol solution 40%, fluorine polysilicates
22%th, schmigel %7, water 25%.
It is an advantage of the invention that possessing more preferable impact resistance and lower fragility, while also possess the resistance to of inorganic binder
High temperature, the advantages of adhesive strength is good, so as to improve its physics performance, more preferably meet needs of production.1300 degree of heating
Shrinkage factor is less than 4% within 24 hours, reduces by more than 18% than original powder-type cost, pyroconductivity is less than or equal to 0.16, and glues
Connect intensity and reach 10kgf/cm2.
Embodiment
High-temperature agglomerant is divided into inorganic binder and the major class of organic binder bond two.Inorganic binder has excellent high temperature resistant
Performance, adhesive strength is good, but resistance to acids and bases and poor water resistance, and fragility is big, not impact resistance.And organic binder bond is with organic viscous
It is main formula to tie agent carboxymethyl sodium cellulosate, is mixed into tackifier, reinforcing agent and preservative, turns into pellet organic binder bond,
Or add oxidant, accelerator and tackifier are etherified is reacted to around tying mining organic binder bond.Its advantage is to improve iron
Grade, energy consumption is reduced, improve yield.The use range of both inorganic binder and organic binder bond is had nothing in common with each other.
The present invention is that technical staff passes through the high-temperature agglomerant that multiple practice summary goes out, and the percentage of its component is：Swelling
Soil 5%~8%, silicon sol solution 38%~42%, fluorine polysilicates 20%~25%, schmigel 6~10%, water 20%~25%；Each component
Sum is 100%.
Use said components prepare the preparation process of high-temperature agglomerant for：First each component is got ready by required usage ratio；
Then bentonite, silicon sol solution, fluorine polysilicates, schmigel and water are mixed evenly, are heated to 60~70 DEG C of bar
4 hours are stood under part, 30~35 DEG C is then cooled to and cures 3 hours, both obtain high-temperature agglomerant.
Technical staff has found that the preferred weight percent that high temperature connects agent is in multiple practice：Bentonite 6%, Ludox are molten
Liquid 40%, fluorine polysilicates 22%, schmigel %7, water 25%.
Bentonite is a kind of claystone, also known as smectite clay rock, containing a small amount of illite, kaolinite, galapectite, green mud
