Abstract
The invention discloses flame-retardant high-temperature-resistant hydraulic filter paper with glass fibers for filters. The flame-retardant high-temperature-resistant hydraulic filter paper comprises, by weight, 50-55 parts of the alkali-free ultrafine glass fibers with the sizes of 3-5 millimeters, 55-60 parts of bleached needle-point leaf wood pulp, an appropriate quantity of distilled water, 0.8-1 part of anionic polyacrylamide, an appropriate quantity of concentrated sulfuric acid with the concentration of 98 wt%, 10-12 parts of nanometer titanium dioxide, 20-25 parts of ferriferous oxide colloidal solution with the solid content of 30%, an appropriate quantity of absolute ethyl alcohol, 60-65 parts of fluorine-silicon emulsion with the solid content of 40 wt%, 3-4 parts of expanded graphite, 6-7 parts of bentonite, 0.035-0.04 part of sodium hexametaphosphate, 0.6-0.7 part of sodium carbonate, 1.8-2.1 parts of cetyl trimethyl ammonium bromide and 0.8-1.1 parts of fungacetin. The flame-retardant high-temperature-resistant hydraulic filter paper has the advantages that the flame-retardant high-temperature-resistant hydraulic filter paper is good in high-temperature ageing resistance and flame retardance and can be used in hot hydraulic oil environments, and accordingly the safety of oil products can be guaranteed.
Description
Technical field
The present invention relates to filter paper technical field, particularly relate to a kind of glass fiber flame retardant high-temperature resistant hydraulic filter filter paper.
Background technology
Nowadays Chinese society is developing rapidly, and enterprise can select mechanically actuated mode in work progress mostly.Constantly perfect with science and technology, in terms of mechanically actuated, enterprise has applied the form of construction work of electromechanical integration all.During mechanical use, no matter how careful operator is to installation and the operation of equipment, all being not fee from the pollution causing hydraulic oil in various degree, the maintenance of hydraulic oil will take for substantial amounts of time and expense, and therefore hydraulic oil becomes of paramount importance parts during machinery uses.Machinery is in use, mainly operated by the through miscellaneous part of hydraulic oil, owing to moisture, gas inclusions dust are mixed in hydraulic oil, to cause hydraulic oil produces oxidation, cause the formation of foam, incrustation and greasy filth, directly affect the using effect of machinery, also result in sizable infringement to machinery simultaneously, hydraulic oil filtration system can reduce the incidence of this phenomenon, avoid that the phenomenon that hydraulic oil is contaminated in use occurs as far as possible, it can be seen that the filtration system of hydraulic oil directly affects the service life of machinery.
A kind of water-base resin with excellent hydrophobic oleophilic oil performance prepared in the preparation of the hydrophobic oleophilic oil organo-mineral complexing emulsion " and in the application study of oil-water separation filter paper " literary composition, prepare efficient water-oil separating resin by the method for organo-mineral complexing and be applied to filter paper impregnation, give filter paper with efficient water-oil separating performance simultaneously, substantially increase filter paper strength character and service life.Filtration filter paper is after complex emulsions dipping, and its surface presents double micro-rough structure, gives filter paper super-hydrophobic/super-oleophilic performance, and water-oil separating rate can be up to 99.6wt%.But the filter paper used herein is ordinary filter paper, not there is good heat resistant, corrosion resistance, and filter paper can be destroyed and be caused filtration inefficiencies under stress for a long time, so can directly promote and produce into, a kind of filter core filter paper that can be convenient for changing should be developed, certain pressure can not only be resisted, possesses good intensity, can use in high-temperature oil liquid, and can be good at moisture present in filtered fluid force feed and the mechanical admixture particle etc. in system, simultaneously cost-effective.
Content of the invention
The object of the invention is contemplated to make up the defect of prior art, provides a kind of glass fiber flame retardant high-temperature resistant hydraulic filter filter paper.
The present invention is achieved by the following technical solutions:
A kind of glass fiber flame retardant high-temperature resistant hydraulic filter filter paper, it is made up of the raw material of following weight portion: 3-5 millimeter superfine E-glass fibre glass fibre 50-55, bleaching needle-point leaf pulp 55-60, distilled water is appropriate, PAMA 0.8-1, concentration is that the concentrated sulfuric acid of 98wt% is appropriate, nano titanium oxide 10-12, solid content is the ferroferric oxide gel solution 20-25 of 30%, absolute ethyl alcohol is appropriate, the fluoro-silicone emulsion 60-65 of solid content 40wt%, expanded graphite 3-4, bentonite 6-7, calgon 0.035-0.04, sodium carbonate 0.6-0.7, cetyl trimethylammonium bromide 1.8-2.1, triacetin 0.8-1.1.
Described a kind of glass fiber flame retardant high-temperature resistant hydraulic filter filter paper, is made up of step in detail below:
