The preparation method of a kind of ceramic metal sealing ring, comprises the following steps:
(1) first sodium hydroxide is added to the water and is configured to the solution of 10-12mol/L, then with nano titanium oxide P25 mixing ultrasonic disperse uniformly after jointly add reactor, by reactor in 150-200 DEG C of Water Under thermal response 10-15h, after cooling, pH is adjusted to neutrality, add nano silicon, hydroxyethyl cellulose and Tween-80 dispersed with stirring uniform, obtain modification liquid；
(2) aluminium oxide, zinc oxide, Co50 cobalt-based alloy powder are pressed and added titanate coupling agent stirring 0.5-1h after solid-liquid weight ratio 1:1-1:2 mixes with dehydrated alcohol, add remaining raw mill after ethanol is distilled off uniformly, obtain mixed powder；
(3) add suitable quantity of water with the mixed powder in step (2) after being mixed by the modification liquid in step (1) to stir, it is spray-dried under the conditions of inlet temperature 260-280 DEG C, outlet temperature 100-120 DEG C with first passing through spray drying tower after ball mill ball milling 4-6h, then at 200-300 DEG C of insulation 0.5-1h, then 600-700 DEG C of process 4-6h under nitrogen atmosphere, ball milling 0.5-1h again after cooling, obtains modified powder；
(4) the modified powder pressed compact in step (3) is placed in it is connected with in the sintering furnace of inert gas shielding atmosphere 1550-1650 DEG C of sintering 2-4h, obtain ceramic metal sealing ring.
The invention have the advantage that
The present invention is first with water heat transfer titanium nanotube, then by itself and nano silicon, hydroxyethyl cellulose is mixed and made into modification liquid, with aluminium oxide, zinc oxide, after Co50 cobalt-based alloy powder mixed powder is blended uniformly, it is coated on mixed powder surface by spray drying, carbon-titanium nanotube-silicon dioxide compound coating layer is formed on mixed powder surface, effectively improve the compactness of material, adhesive property and toughness, again by the selection of raw material with compounding, make the ceramic metal sealing ring not only corrosion resistance and good prepared, and shock resistance, cracking resistance is improved, there is good stability and ruggedness, service life is long, and there is the anti scuffing of excellence, abrasion resistance properties, it is applicable to mud immersible pump use.
