High-temperature resistant fuel oil filter paper and preparation method thereof

Abstract

The invention discloses high-temperature resistant fuel oil filter paper and a preparation method thereof. The high-temperature resistant fuel oil filter paper comprises, by weight, 70-80 parts of hardwood pulp, 20-30 parts of polybenzimidazole fiber, 10-20 parts of modified activated carbon fiber, 2-5 parts of modified kaoline, 1-3 parts of nano calcium carbonate, 2-4 parts of silica gel, 1-2 parts of nano titania, 0.5-0.8 part of decabromodiphenyl ethane, 2-3 parts of polyvinyl acetate emulsion, 1-2 parts of polyvinyl alcohol, 0.5-1 part of n-butyl methacrylate, 0.5-1 part of phenyl-triethoxysilane, 0.4-0.8 part of sodium lauryl sulfate, and 2-5 parts of polyethyleneimine. The high-temperature resistant fuel oil filter paper prepared is good in water permeability, large in filtering area, small in maximum hole diameter, high in filtering precision, strong in bursting strength, high in temperature resistance and tensile strength and the like, has stable performance index under normal-temperature and high-temperature working conditions and is provided with good temperature resistance and filtering effects, filtering efficiency of the high-temperature resistant fuel oil filter paper can reach 99.98%.

Description

technical field [0001] The invention relates to filter paper for a filter, in particular to a high-temperature resistant fuel filter paper and a preparation method thereof. Background technique [0002] The fuel filter is a device used to filter out other solid impurities mixed in the fuel. Its function is to filter out harmful particles and water in the engine fuel, so as to protect the oil pump nozzle, cylinder liner, piston ring, etc., and reduce wear and tear. , to avoid clogging. Remove iron oxide, dust and other solid impurities contained in the fuel to prevent the fuel system from clogging (especially the fuel injector). Reduce mechanical wear, ensure stable engine operation, and improve reliability. Among them, the filter element plays the role of filtering fuel. The filter element of the fuel filter is mostly made of filter paper, so the quality of the filter paper directly affects the efficiency of the filter element to filter fuel. The existing filter paper has ...

Among them, the filter element plays the role of filtering fuel. The filter element of the fuel filter is mostly made of filter paper, so the quality of the filter paper directly affects the efficiency of the filter element to filter fuel. The existing filter paper has poor adsorption, low filtration efficiency, and high temperature resistance. Poor performance, low tensile strength and other shortcomings limit its service life
