Abstract

The invention relates to filter paper for an environmental-friendly automobile filter. The filter paper for the environmental-friendly automobile filter is prepared from the following components in parts by weight: 1-5 parts of far infrared ceramic powder, 2-20 parts of sepiolite nanofibers, 0.8-1.6 parts of a silane coupling agent, 0.8-1.6 parts of a diluent, 9-20 parts of a sizing agent and 60-96 parts of wood pulp. Air, fuel oil and engine oil filters made of the filter paper are obvious in comprehensive effect; pollutants generated by exhaust gas emission of an automobile are reduced by 16-47%; the dynamic performance is improved by 6-12%; fuel oil can be saved by 2-5%; the emission standard reaches the European IV standard.

Description

technical field [0001] The invention relates to filter paper for a filter, in particular to a filter paper with an environmental protection function and a manufacturing method thereof, belonging to the technical field of automobile environmental protection. Background technique [0002] The rapid development of the automobile industry has brought prosperity and convenience to mankind. However, with the sharp increase in the number of automobiles, the environmental problems caused by automobile emissions have emerged. Nitrogen oxides, volatile organic compounds, and inhalable particulate matter in emissions account for 66%, 90%, and 26% of all pollution sources in central urban areas, respectively. Automobile filters have the function of filtering fuel, air and engine oil. The filter element is its main filtering part and undertakes the filtering work. The research on filter materials is directly related to the filtering effect. In recent years, the intensification of air po...
