Problems solved by technology

[0004] (1) Low filtration efficiency and poor filtration accuracy lead to low filtration efficiency of the filter, which can only filter out 50% to 60% of impurities;
[0005] (2) Poor properties such as high temperature resistance, water resistance, and burst resistance, resulting in short service life;
[0006] (3) Large fluctuations in quality and poor stability
However, the particles retained by the filter paper tend to stay in the pores of the filter material in large quantities, causing the pores to be blocked, thereby affecting the service life.

Abstract

The invention belongs to the field of papermaking, and in particular relates to a car filter paper made of coal gangue and fly ash inorganic fibers and a preparation method thereof. The filter paper is composed of coal gangue and fly ash inorganic fibers, wood pulp fibers, and PVA fibers. , silane coupling agent YDH-151, polyoxyethylene, silicone oil, the weight percentage of each component is based on dry pulp, coal gangue and fly ash inorganic fiber: 20% to 50%; wood pulp fiber: 30% to 70%; PVA fiber: 2% to 5%; silane coupling agent YDH-151: 1% to 10%; polyoxyethylene: 1% to 8%; silicone oil: 1% to 10%; the inorganic fiber filter paper It has the characteristics of strong rigidity, low moisture absorption deformation, easy to form a good and stable network structure, high porosity and low filtration resistance. And the filter material is water-resistant, oil-resistant, high-temperature resistant, chemically stable, and flame retardant. The filter paper made of coal gangue and fly ash inorganic fiber can also be used for other aspects of air filtration and oil filtration.

Description

Technical field [0001] The invention belongs to the field of automobile filter papers, and particularly relates to an automobile filter paper made of coal gangue and fly ash inorganic fibers. Background technique [0002] Automobile filter paper is one of the main raw materials for the production of automobile filters. It is also called "auto three filter paper", namely air filter paper, fuel filter paper, and oil filter paper. Filters are used in internal combustion engines such as automobiles, ships, and tractors to act as the “lungs” of automobile engines to remove impurities in air, oil and fuel, prevent the wear of engine parts, and extend their service life. There are many filter materials for filters, such as cellulose, felt, cotton yarn, non-woven fabric, metal wire and glass fiber, etc., which are basically replaced by resin-impregnated paper filter elements. With the rapid development of the world automobile industry, Using filter paper as a filter material has been wi...
