Preferably, described modified nano-titanium dioxide ptfe emulsion is using tetrafluoroethylene monomer to be main former
Material, adds modifying agent nano titanium oxide and prepares.
Modified nano-titanium dioxide ptfe emulsion intrusion filter paper fibre surface, causes emulsion by rolling, sintering
Firm envelope is on filter paper fibre, and it can retain the filtering function of former filter paper, and filtering accuracy and gas permeability and former filter paper
It is little compared to change, but its water resistance, temperature tolerance, acid and alkali-resistance and corrosion resistance, wearability and intensity and non-deformability have
Large increase, can reverse gas cleaning, Reusability capable of washing adds hydrophobic oleophylic function, available for water-oil separating.
The filter paper used in fuel filter of the present invention uses asbestos fibre, and high density cotton linter pulp, polypropylene fibre, alkali-free glass fibre is short
Body paper is made in chopping and ceramic fibre, wherein it is more poor to solve existing China's timber resources using corn stalk fiber,
It need to rely on import beautiful, rice stalk fibre, corn stalk fiber, which substitutes wood pulp cellulose, has the spy for the cost that economizes on resources, reduces
Point；Asbestos fibre has a flame retardant effect, and cotton linter is a kind of resourceful, reproducible, extremely leaved for development, special non-wood
Material raw material.Cotton pulp has its unique distinction compared with wood pulp, straw pulp, and its containing cellulose is purer, and fiber is elongated and flexible, tough and tensile resistance to
Folding, soft, absorbent properties are good, the opacity with height, and can be with prolonged preservation；And polypropylene fibre has matter
Gently, intensity height, good, wear-resisting, the corrosion resistant characteristic of elasticity, are also a kind of synthetic fibers, and alkali-free glass fibre is chopped silk with increasing
Effect of strong fibre strength, ceramic fibre shape lightweight refracrory, with lightweight, high temperature resistant, heat endurance be good, thermal conductivity
It is low；Can play synergy using four kinds of fibers as fibrous raw material, obtained body paper have it is fire-retardant, it is water-fastness, temperature tolerance, resistance to
Mill property, resistance to acids and bases, heat endurance are good, the characteristic of light weight.
Amphiprotic polyacrylamide is added in the preparation process of body paper, various slurries, which can be respectively provided with, strengthens and help well
Stay drainage and auxiliary sizing efficiency.Modified starch precipitated calcium carbonate is added because the whiteness of precipitated calcium carbonate PCC fillers is higher,
So that the whiteness of body paper is also higher, while the filler improves the physical property of body paper, it can not only improve the performance of paper, also
Fibre material can be saved.Polyethylene glycol oxide has the performances, polyoxy such as flocculation, thickening, sustained release, lubrication, scattered, retention, water conservation
Beating time can also be shortened by changing ethene, the paper pulp that beating degree can be used relatively low, the good paper of evenness of manufacturing paper with pulp out, while paper
Page flexibility and intensity are all preferable.The polyethylene glycol oxide of 2500000~3,000,000 molecular weight, its extensibility macromolecular structure is prevented
Contacting with each other for long fibre surface, improves the viscosity of slurry suspension body, therefore limits the generation of fiber flocculation, magnesia-alumina
Hydrotalcite also has anti-fire effect.
Pass through three dippings in the operating procedure of dipping so that the water resistance of obtained filter paper, temperature tolerance (can be at 200 degree
Be used for a long time below), good non-stick, acid and alkali-resistance and corrosion resistance, wearability and intensity and non-deformability have and carry greatly very much
Height, can reverse gas cleaning, Reusability capable of washing adds hydrophobic oleophylic function, available for water-oil separating.
Carbon fiber is a kind of efficient absorption separation function material, with than the more excellent absorption of powdery or granular active carbon
Ability, the adsorption capacity to harmful gas component is 1-10 times of traditional product, and compound carbon fiber layer causes filter paper on filter paper
Possesses the function of removing pernicious gas and bacterium.
