Abstract
The present invention relates to a short fiber filter element of a filter and a manufacturing method thereof. Thermosetting resin and natural short fiber are used as main raw material, and after acetanilide, pyrrolidone and sodium dodecylbenzene sulfonate are added and are uniformly mixed, the filter element is formed by high temperature sintering. The thermosetting resin and the short fiber are used as the main raw material, and the present invention is formed by sintering; therefore, the present invention has the advantages of simple manufacturing technology and low cost. Manufactured products have the characteristics of favorable water resistance, favorable high temperature resistance, favorable acid resistance and favorable alkali resistance; the products which can be used at the high temperature of 140 DEG C for a long time have the advantages of no softening, no coking, good rigidity of filtering hole diameters, no deformation and high filtering accuracy. Crenas are arranged on the surface of the outer wall of a filter element barrel; therefore, filtering area is increased, and dirt containing amount is enhanced. The short fiber filter element which is used as the filter element of an engine oil filter of an internal combustion engine in automobile industry is better than JB/T5087-91 standard issued by a ministry.
Description
The invention belongs to cleaner filter core technical field, in particular a kind of short-staple filter element for cleaner and manufacture method.
At present, the short fiber filter core has replaced the filter core of paper material, still, because composition of raw materials is unreasonable and manufacturing process is complicated, to making inefficiency, the filter core cost height that makes, filtering weak effect.
The purpose of this invention is to provide a kind of composition of raw materials is reasonable, manufacturing process is simple, cost is low, filtering is effective short-staple filter element for cleaner and manufacture method, to overcome the defective that prior art exists.
The object of the present invention is achieved like this: with short fiber and thermosetting resin is primary raw material, adds auxiliary agent, makes filter core through high temperature sintering, and it is as follows specifically to fill a prescription: (by weight)
Thermosetting resin 35-45 short fiber 50-60 acetanil 8-12
Pyrrolidones 8-10 neopelex 1-2
Above-mentioned thermosetting resin comprises unsaturated-resins such as 665 type phenolic resins, acetal resin; Short fiber comprises various animal hairs, and various strings are as cotton, flax fiber.
Manufacture method of the present invention is as follows: at first with raw wool and string washes clean, dry, being ground into length is the 1-1.8 millimeter; Unsaturated-resin is ground into 80-100 order powder, then, weigh by above-mentioned prescription, the mixing and stirring filter core mould of packing into, the mould that will install batch mixing was again put into the sintering furnace sintering 16-19 minute, and sintering temperature is 245-285 ℃, the demoulding immediately after sintering is come out of the stove, workpiece is repaired, and last bonding upper and lower end cap is made finished product.
By above-mentioned prescription and the prepared filter element of manufacture method, its structure is cylindric, and the filter cylinder outer surface is provided with knuckle-tooth, to increase the filter core area, improves filter efficiency.
It is the machine oil filtering and the hydraulic oil filtering of power with the internal combustion engine that the present invention can be used for automobile, tractor, loading machine, engineering machinery etc.
Good effect of the present invention is: owing to adopted thermosetting resin and short fiber is primary raw material, form through sintering, manufacturing process is simple, and cost is low, and the product that makes has good water-fast, high temperature resistant and acid and alkali-resistance characteristic, can under 150 ℃ of high temperature, use for a long time, not softening, not coking, the pore size filter rigidity is good, indeformable, the filtering accuracy height.The filter core cylinder outer wall surface is provided with knuckle-tooth, thereby has increased filter area, has improved pollutant holding capability.Be used for automobile industry as the I. C. engine oil filter element, be better than the JB/T5087-91 ministry standard.
Further narrate the present invention below in conjunction with embodiment.
