Abstract

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.

Description

technical field [0001] The invention relates to a gasoline engine particulate filter, in particular to a composition of the gasoline engine particulate filter and a preparation method thereof. Background technique [0002] As people pay more attention to environmental protection, more and more stringent gasoline vehicle emission regulations will be formulated and implemented. On May 6, 2015, the International Symposium on Motor Vehicle Emission Control Technology and Supervision was held in Wuhan. In terms of the implementation date of China VI, strive to implement it nationwide in 2020 (using the Chinese working condition system), referring to Euro 5 and Euro 6 standards Introduces particulate mass emission standards for positive ignition vehicles fitted with direct ignition engines. Gasoline engine exhaust particles are small, low in concentration, and high in temperature. When applied to a gasoline engine particulate filter (GPF) carrier, it needs to withstand thermal sh...
