Component of gasoline engine particulate filter and preparation method of component
The invention discloses a component of a gasoline engine particulate filter and a preparation method of the component. The component comprises 35-45 parts of talc powder, 10-15 parts of aluminium hydroxide, 5-15 parts of kaolin, 10-15 parts of silica powder, 5-15 parts of boehmite, 0-4 parts of hydroxypropyl methyl cellulose, 0-10 parts of graphite powder, 5-15 parts of shell powder, 0-10 parts of starch, 10-25 parts of high-molecular plastic particles, 0-2 parts of mineral oil, 0-1 part of stearic acid and 25-35 parts of water. Raw materials, namely, the talc powder, the aluminium hydroxide, the kaolin, the silica powder and the boehmite, are mixed firstly, then a pore-forming agent is added in proportion, finally, a binder is added, cross pore blockage is performed, the gasoline engine particulate filter is prepared through sintering, the porosity of the prepared gasoline engine particulate filter is up to 60%-65%, the pore diameter is up to 20-30 mu m, the porosity of a carrier is greatly increased, the pore diameter is increased, so that the exhaust fluency of the carrier is improved, and blockage is prevented.
