Abstract
The invention discloses high-purification-rate high-strength honeycomb ceramic. The ceramic is composed of the components of, by weight: 30-50 parts of cordierite, 20-40 parts of alumina, 2-8 parts of yttrium oxide, 2-10 parts of titanium dioxide, 10-20 parts of clay, 10-25 parts of talc powder, 2-8parts of stearic acid, and 10-26 parts of deionized water. Compared with prior art, the high-purification-rate high-strength honeycomb ceramic is prepared with rare earth metal, titanium dioxide, and the like with a special ratio, such that cost is low, and purification rate is high. Also, the ceramic has the advantages of high strength, high-temperature resistance, and long service life. The ceramic can be used under a temperature of 1500-1700 DEG C. The preparation process is simple, and sintering temperature is reduced, such that energy-saving and consumption-reducing purposed can be achieved.
Description
Technical field
The invention belongs to ceramic field, relate in particular to a kind of high purification rate, high strength ceramic honey comb and preparation method thereof.
Background technology
The raising to automobile exhaust emission standard with various countries that increases considerably along with car owning amount, treating vehicle exhaust more and more comes into one's own, the three-element catalytic technology that the ceramic honey comb of wherein take is carrier is considered to effective and the most feasible improvement technology at present, and it can change hydrocarbon polymer harmful in tail gas, oxynitride and carbon monoxide into nontoxic carbonic acid gas, nitrogen G&W simultaneously.For this reason, people are deepening constantly the research of three-element catalytic technology, to improve the cost of processing efficiency and reduction catalyzer.
At present topmost automobile catalyst factory also all adopts the formula of precious metal system in the world.At these, take in the catalyzer that precious metal is active component, the content of precious metal is all higher, and general bullion content can reach every liter more than 1.0 grams.Because the resource of precious metal is in the world very limited, expensive, therefore, adopt the technology of precious metal in large-scale application, to be subject to certain restriction.
Because the fracture toughness property of cordierite honeycomb ceramic is lower, thus its bending strength and wear resisting property poor; Therefore to ask for something fastness to rubbing and physical strength compare Gao field, just can not only adopt traditional trichroite is material preparation.
