Abstract
A staple core of filter is made up of thermosetting resin, natural staple, sodium sulfate and citric acid through uniform mixing and high-temp sinter. Its advantages include uniform apertures, high hardness, high dirt-holding capacity, wide temp range, not degumming after immersed for a long time, not cracking, crisping and softening, low initial resistance less than 0.016 MPa and high initial efficiency higher than 64%.
Description
The present invention relates to cleaner with filter stamen material technology field, exactly is to disclose a kind of short fiber filter stamen material and production technology, can be widely used in the manufacturing of the oil filter filter stamen of internal combustion engine.
The filter stamen is the critical component of I. C. engine oil cleaner, and its quality quality directly affects cleaner work quality height, and conventional motor vehicle filter stamen is to be made by materials such as filter paper, nonwoven, felts, exists following shortcoming:
1. temperature tolerance is poor, and when the oil temperature surpassed 100 ℃, filter paper became fragile, viscose glue dissolves, and causes breakage, did not have the effect that purifies machine oil.
2. poor water resistance, because the running of engine, temperature raises, oil itself contains the easier paper pulp that makes of moisture and decomposes, and makes filter stamen distortion and damaged.
3. the own intensity of paper stamen and nonwoven cloth material is lower, when lubricating oil under pump function, filter stamen surface apertures is compressed and diminishes, and causes that resistance increases, flow reduces, pollutant holding capability diminishes, useful life shortens, and influences the cleaner operate as normal.
The invention provides a kind of cleaner short fiber filter stamen material and production technology, its purpose has been intended to solve the above-mentioned shortcoming deficiency that materials such as filter paper, nonwoven, felt filter stamen exists.
For realizing purpose of the present invention, concrete solution is as follows: adopting thermosetting resin, atural staple fibre (as animal hair, silk floss, fiber crops etc.) is primary raw material, adds auxiliary agent, through high temperature sintering, processing and forming is made the filter stamen that aperture precision is even, pollutant holding capability is big, compositing formula by weight:
Thermosetting resin 80-160 atural staple fibre 100-250
Hexamethylenetetramine 8-15 sodium sulphate 5-20
Citric acid 1-6
Above-mentioned material is taken by weighing respectively, wherein thermosetting resin, hexamethylenetetramine are ground into 60-200 order powder, natural fiber shreds into the short fiber of 2-6mm, mix the mould of packing into sodium sulphate, citric acid, and put into the sintering furnace sintering 20-40 minute, sintering temperature is 210-240 ℃, promptly gets product of the present invention.In addition,, prevent decortication, fall bits, this product can be put into by epoxy resin 5-15 part for making properties of product of the present invention better, acetone 65-85 part, ethylenediamine 1-1.5 part was soaked 8-24 hour in the liquid that ethanol 5-15 part is modulated into, dry getting final product after taking out.
Good effect of the present invention is: with thermosetting resin, atural staple fibre etc. is primary raw material, the sinter molding back aperture is even, quality is hard, pollutant holding capability is big, and temperature resistant range is wide, after tested, do not come unstuck in-40-140 ℃ long-time an immersion, do not break, not embrittlement, softening, less than 0.016MPa, original efficient is higher than the oil strainer stamen that 64%, two index all is better than papery or other material to original resistance in the nominal volume flow.
Further narrate the present invention below in conjunction with embodiment.
Embodiment 1:
Get phenolic resins 800g, hexamethylenetetramine 80g is ground into 100 order powder, and animal hair 1000g shreds into the short fiber about 3mm, mix with 60g sodium sulphate, 1g citric acid, stirring packs into filters in the stamen mould, goes into the stove sintering 35 minutes, and Control for Kiln Temperature is at 210 ℃.
Embodiment 2:
Take by weighing amino resins 1000g, it is Powdered that hexamethylenetetramine 100g is ground into 150 orders, and flaxen fiber 150g shreds into the short fiber of 4mm, and with 100g sodium sulphate, 2g citric acid mixing and stirring is packed in the mould, carries out sintering 30 minutes, and sintering temperature is 220 ℃.
Embodiment 3:
With polyformaldehyde 1600g, it is Powdered that hexamethylenetetramine 140g makes 150 orders, and pig hair 2000g shreds into the short fiber of 6mm, add in the mould of packing into after sodium sulphate 200g, citric acid 58g stir, and sintering 40 minutes, sintering temperature is 240 ℃.
Embodiment 4:
Extracting epoxy resin 70g, acetone 700g, ethylenediamine 7g, ethanol 80g are modulated into liquid after mixing, and soak 18 hours in the product input liquid with embodiment 1, embodiment 2 and 3, and temperature is under room temperature state.
