Abstract
A kind of high temperature resistant inorganic composite adhesive belongs to high temperature inorganic coagulation material field, and this inorganic compounding tackiness agent is to be raw material with phosphoric acid, Tai-Ace S 150, ultrafine aluminium hydroxide and metallic aluminium, and water is dispersion medium, safety non-toxic.Its concrete component is: Al
2O
3, 15-20wt%, P
2O
510-12wt%, SO
310-12wt%, surplus is a water.
Inorganic adhesive provided by the invention, refractoriness is higher 50～60 ℃ than biphosphate agglutinating under the aggregate same case, and it is average weightless little, bonding back room temperature strength is up to 31.6MPa, than high by 85% with the aluminium dihydrogen phosphate agglutinating, this tackiness agent has good wettability with alumina, firm soil, mullite, zircon, carbon and carbide, fireclay etc.

2] and silicon sol etc. be representational inorganic adhesive, be to make unshape refractories such as mould material, coating and Gunning refractory tackiness agent commonly used.But they begin to decompose under not too high temperature.For example, phosphate-basedly decompose more by force 1200 ℃ of beginnings, silicate ties up to 900 ℃ of beginning serious decomposition, and the result of decomposition loses cohesive action gradually, thereby the use temperature of bonded material is restricted.
The object of the present invention is to provide a kind of new high temperature resistant inorganic composite adhesive, it is to be raw material with phosphoric acid, Tai-Ace S 150, ultrafine aluminium hydroxide and metallic aluminium, and water is dispersion medium, safety non-toxic.High temperature resistant inorganic composite adhesive provided by the invention is a kind of composite gelled material, with corundum, alumina, zircon, carbon, carbide and fireclay etc. good wettability and glue performance are arranged all, can be mixed with whole construction material and repair with material, building materials and joint filler various unshape refractories such as high-temperature resistance energy-saving coating with these aggregates.
The concrete component (weight) of high temperature resistant inorganic composite adhesive provided by the invention is: Al
2O
315-20%, P
20
510-12%, SO
310-12%, surplus is H
2O.
Its making method is also very simple, phosphoric acid need only be heated, and adds ultrafine aluminium hydroxide (320 orders are following) and stirs evenly, yet add metallic aluminium and Tai-Ace S 150, and is water-soluble after preparing in above-mentioned component ratio, stirs, and can obtain.
The Al of inorganic composite gel material provided by the invention
2O
3Content is than high nearly one times of the content of commodity aluminium dihydrogen phosphate, and is in the colloid with gluing form.Thereby its refractoriness ratio of refractory product that uses tackiness agent provided by the invention to make raising greatly of aluminium dihydrogen phosphate.
For further specifying effect of the present invention, now compare in many-sides such as ultimate compression strength, refractoriness, linear shrinkage, refractorinesss under load with the aluminium dihydrogen phosphate matrix material in conjunction with the embodiments.
1, the concrete prescription of embodiment is: phosphoric acid 27%, ultrafine aluminium hydroxide 6%, metallic aluminium powder 0.5%, Tai-Ace S 150 25%, water 41.5%(are weight).With this composite adhesive and just soil, alumina, zirconium not refractory aggregate such as stone, fireclay be mixed with sample (table 1)
Table 1
| Material name \ content (weight) | ％ |
| Refractory aggregate commodity aluminium dihydrogen phosphate or water of the present invention | 79.6 13.0 7.4 |
Condition of cure: 300 ℃ of 2hr are warming up to 500 ℃ then, are incubated 2 hours, naturally cooling.
2, both performance comparison
(1) ultimate compression strength, refractoriness and refractoriness under load
| The sample classification | Mean compressive strength (MPa) | Refractoriness (℃) | Refractoriness under load (℃) |
| Commodity aluminium dihydrogen phosphate bonding adhesive bonds of the present invention | 16.9 31.6 | 1730 ＞1790 | 1360 1370 |
2, weightlessness and morphology observation after the high-temperature calcination
| The sample classification | Average weightless (%) | Morphology observation | Calcination condition |
| Commodity aluminium dihydrogen phosphate bonding | 1.9 | Gross distortion, surface are glassy phase | 1730-1750 ℃ is incubated 4 hours |
| Adhesive bonds of the present invention | 1.5 | Sample is complete | The same |
3, heavily burn linear shrinkage
| The sample classification | Average line shrinks (%) | Treatment condition |
| Commodity aluminium dihydrogen phosphate bonding adhesive bonds of the present invention | 1.46 0.83 | 1450℃,2hr 1450℃,2hr |
This shows, inorganic compounding adhesive provided by the invention, the characteristics that have are:
1, under orthopaedics situation the same terms, refractoriness is also higher 50～60 ℃ than aluminium dihydrogen phosphate commonly used on the market, and this is because Al2O
3The cause that content is high. So a kind of novel fire resistant adhesive.
2, inorganic compounding adhesive provided by the invention, through 1720-1750 ℃, after being incubated 4 hours and processing, not only average weightless few, more important is that specimen configuration is intact, so especially suitablely at high temperature use;
3, the room temperature mean compressive strength of inorganic compounding adhesive provided by the invention is higher by 85% than what bond with aluminium dihydrogen phosphate, reach 31.6MPa, and the reheating linear shrinkage is little, is suitable for repeatedly repeatedly recycling of high temperature → normal temperature.
4, inorganic compounding tackiness agent provided by the invention, abundant raw material, cost is lower by about 50% than aluminium dihydrogen phosphate, and is dispersion medium with water, safety non-toxic.
In a word, inorganic compounding tackiness agent provided by the invention has good wettability and gummed property with just soil, alumina, mullite, zircon, carbon and carbide, fireclay etc., and its thermostability, mechanical property all are better than tackiness agent such as traditional commercially available phosphate-based, alkalimetal silicate system.
