Abstract

The invention discloses mineral cotton fiber filter paper for a fuel filter and a preparation method of the mineral fiber filter paper. The mineral fiber filter paper comprises, by weight, 50-60 parts of bamboo pulp, 40-50 parts of mineral cotton fiber, 10-20 parts of glass fiber, 2-5 parts of zeolite molecular sieve, 1-3 parts of sodium bentonite, 2-4 parts of modified calcium carbonate, 1-2 parts of modified activated carbon, 2-3 parts of polyvinyl acetate emulsion, 1-2 parts of nanometer aluminum oxide, 0.5-0.8 part of triphenyl phosphate, 3-4 parts of coumarone resin, 0.5-1 part of lignosulfonate, 0.5-1 part of silane coupling agent DL602, 0.4-0.8 part of sodium lauryl sulfate, 0.5-1 part of antioxygen DLTP, and 4-6 parts of wet strength agent PAE (polyamide epichiorobydrin resin). The mineral cotton fiber 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 water resistance 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, and filtering efficiency of the mineral cotton fiber filter paper can reach to 99.95%.

Description

technical field [0001] The invention relates to filter paper for a filter, in particular to a mineral wool fiber filter paper for a fuel filter 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...
