Embodiment Construction

[0030] Preparation of automotive engine oil filter material:

[0031] (1) The ratio of fiber raw materials is as follows: plant fiber 50%, inorganic fiber 30%, synthetic fiber 20%.

[0032] (2) Plant fiber is dispersed in 0.01% PEO solution, glass fiber is dispersed in 0.1% HCL and 0.3% OP-6 solution, polyester fiber is dispersed in 0.01% CMC and 0.5% NP-9 solution.

[0033] (3) The slurry is formed on the Internet. The concentration of plant fibers in the slurry is 0.1% by weight, the concentration of inorganic fibers is 0.05% by weight, and the concentration of synthetic fibers is 0.05% by weight;

[0034] (3) dehydration and drying;

[0035] (4) Adding a reinforcing agent with an amount of 15% by weight of the total amount by surface coating or dipping, and the reinforcing agent is a modified polyacrylic resin.

[0036] (5) The material after impregnating the resin is dried and cured to obtain finished products, which are cut and packaged;

[0037] Such as figure 1 As ...

Abstract

A composite fibrous filter material for engine is prepared through adding dispersing assistant to water, ageing, adding plant fibres, inorganic fibres, and synthetic fibres, shaping with net, coating or dipping the reinforcing agent chosen from phenolic resin, epoxy resin, polyacrylic acid, and vinyl polyacetate, drying and solidifying. Its advantages are high filter accuracy and efficiency, low resistance, high physical strength and long service life.

Description

technical field [0001] The invention relates to a filter material, more specifically to a fiber composite filter material specially used for an engine and a preparation method thereof. Background technique [0002] Engine filter materials mainly include air filter, oil filter, and fuel filter material (referred to as "three filter" materials). [0003] Existing engine filter materials use plant fibers. The all-plant fiber filter material mainly relies on the principle of sieving to filter impurities, that is, the filtration accuracy is determined according to the size of the pore size. The disadvantage of this material is that it can only achieve surface filtration of the material, that is, impurities are mainly intercepted by the surface of the material, while smaller impurities basically pass through the filter material. During use, the pores on the surface of the filter material are quickly completely blocked by impurities, and the pores in the deep layer of the materia...
