The high-temperature adhesive has better impact resistance and lower brittleness, and has the advantages of high temperature resistance and favorable bonding strength of the inorganic adhesive, thereby enhancing the physical service performance and better satisfying the practical production demands.
Description
Technical field
The invention belongs to chemical field, particularly to a kind of high temperature adhesive for heat insulating work.
Background technology
High temperature adhesive is again high-temperature adhesives, high temperature adhesives, high temperature adhesive.For water white transparency or yellowish
Thick liquid, soluble in water, in faintly acid, without sodium ion.Bond under the conditions of being applicable to 300 DEG C of high temperature above, the suitableeest
Build by laying bricks or stones for High-temp. kiln or repair.As pottery etc. bonding, various High-temp. kilns, heat-treatment furnace are built by laying bricks or stones and are repaired, stove take turns
The gunning refractory repaiied, and paste aluminosilicate refractory fiber etc..It is the highest is resistant to temperature 1500 DEG C, and the short time is resistant to 1800 DEG C even more
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 of refractory material furnishing has antidetonation, anti-stripping
Fall, resistance to suddenly cold and hot, high temperature resistant airflow scouring, brick are firmly combined with brick, do not fall the features such as brick, not runout.Due to without sodium from
Son, when pasting aluminosilicate refractory fiber, can prevent mullite powdered crystalline, and construction and maintenance is convenient, can save energy 30%～
50%；For building stove by laying bricks or stones or repairing stove, furnace service life 1～3 times can be extended, decrease factory and repair stove expense and idle cost.
But currently used high temperature adhesive is relatively costly, it is impossible to well adapt to the needs in market.
Summary of the invention
It is an object of the invention to provide a kind of with low cost and that adhesive effect is good high temperature adhesive.
A kind of high temperature adhesive, the percentage by weight of its component is: bentonite 5%～8%, silicon sol solution 38%～42%,
Fluorine polysilicates 20%～25%, schmigel 6～10%, water 20%～25%；Each component sum is 100%；
The preparation process using said components to prepare high temperature adhesive is: first each component got ready by required usage ratio；Then
By bentonite, silicon sol solution, fluorine polysilicates, schmigel and water mixing and stirring, under conditions of being heated to 60～70 DEG C
Stand 4 hours, be then cooled to 30～35 DEG C of ripenings 3 hours, both obtained high temperature adhesive.
Further, the percentage by weight of described high temperature adhesive is: bentonite 6%, silicon sol solution 40%, fluorine polysilicates
22%, schmigel %7, water 25%.
It is an advantage of the invention that possess more preferable resistance to impact and lower fragility, also possess the resistance to of inorganic adhesive simultaneously
High temperature, the advantage that adhesive strength is good, thus improve its physics serviceability, more preferably meet needs of production.1300 degree of heating
Within 24 hours, shrinkage factor is less than 4%, reduces by more than 18% than original powder-type cost, and pyroconductivity is less than or equal to 0.16, and glues
Connect intensity and reach 10kgf/cm2.
Detailed description of the invention
High temperature adhesive is divided into inorganic adhesive and the big class of organic adhesive two.Inorganic adhesive has the high temperature resistant of excellence
Performance, adhesive strength is good, but resistance to acids and bases and poor water resistance, fragility is big, not impact resistance.And organic binder bond is with organic viscous
Knot agent carboxymethyl sodium cellulosate is main formula, is mixed into viscosifier, reinforcing agent and preservative, becomes pellet organic binder bond,
Or add oxidant, accelerator and viscosifier etherified be reacted to around tie mining organic binder bond.Its advantage is to improve ferrum
Grade, reduces energy consumption, improves yield.The range of inorganic adhesive and organic adhesive is had nothing in common with each other.
The present invention is the high temperature adhesive that technical staff goes out through repeatedly practice summary, and the percentage ratio 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%.
The preparation process using said components to prepare high temperature adhesive is: first each component got ready by required usage ratio；
Then by bentonite, silicon sol solution, fluorine polysilicates, schmigel and water mixing and stirring, it is heated to the bar of 60～70 DEG C
Stand 4 hours under part, be then cooled to 30～35 DEG C of ripenings 3 hours, both obtained high temperature adhesive.
Technical staff finds in repeatedly practice, and high temperature connects the preferred weight percent of agent and is: 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
Stone, zeolite, quartz, Anhydrite, calcite etc.;Main chemical compositions is silicon dioxide, aluminium sesquioxide and water, possibly together with ferrum, magnesium,
Bentonitic physicochemical properties and process technology performance are affected the biggest by element, Na2O and the CaO content such as calcium, sodium, potassium.Swelling
