Abstract
The present invention provides novel composite fiber which is called botelun. The novel composite fiber uses glass fiber as a basal body, and the outer surface of the glass fiber is coated by a layer of an organic polymer thin film with high temperature resistance, corrosion resistance and good flexibility. Coating organic polymer can be polytetrafluoroethylene, polyimide or polybenzoxazoles. The composite fiber can be long threads or short threads. The present invention also provides a method for producing botelun fiber long threads and short threads, which is characterized in that after the glass fiber is pulled and formed, two work processes of hot coating application, immersion and hot melting or heat formation are additionally carried out. The botelun fiber of the present invention can be used for weaving high-temperature filtering cloth or base cloth, and can be directly combed, overlapped into nets, punctured by needles and treated by other work processes to produce needle-punched felt. When the high-temperature filtering cloth and the filtering material made by the fiber of the present invention are used for a high-temperature bagged dust collector, the using range of the high-temperature bagged dust collector can be widened, and the service life of the high-temperature bagged dust collector can be greatly prolonged.
Description
Technical field
The invention belongs to artificial filament's manufacturing and chemically treated technical field thereof, promptly propose a kind of advanced composite material fiber and manufacture method thereof.
Background technology
Glass fibre is a kind of inorganic materials fiber, and its chemical stability is better, and density is at 2.5～2.7g/cm
3About, specific tenacity surpasses other natural fiber, organic synthetic fibers and various alloy fiber.And it is compared with organic fibre and has good heat endurance, and its performance depends primarily on the composition of glass itself, usually with K contained in the glass
+, Na
+How many ionic is decided to be medium-alkali glass fiber and alkali-free glass fiber, and the softening temperature of these glass fibre is up to 550～750 ℃.Because These characteristics, glass fibre is processed into glasscloth, glasscloth and fiberglass needled mat as high-temperature-resistant filtering material, is widely used in multiple industries such as iron and steel, cement, electric power, waste incineration with cleaning high-temp flue gas and collection micro mist material.But because glass fibre is crisp easy to break, wear resisting property is relatively poor, and is also relatively poor to the solidity to corrosion of some chemical substance such as fluorochemical, and it is very restricted in application facet as high-temperature filter material.In recent years, people have made number of research projects for improving glass dimension high-temperature filter material performance, perhaps with other fiber and glass fibre interlayer manufacturing Nomex, or with other fiber and glass fibre blending with manufacturing blending glass cloth and blending Woven glass cloth.Though obtain certain effect, but still fail to overcome better the glass fibre built-in problem.
Summary of the invention
The objective of the invention is to seek a kind of method that overcomes the above-mentioned shortcoming of glass fibre, reach with this method and make the glass fibre modification, both kept glass fibre itself high temperature resistant, higher advantages such as specific tenacity are arranged; Can improve its flexibility and wear resisting property again, and the ability that improves its anti-fluorochemical and strong corrosive medium.
The invention provides a kind of New-type composite fibre of naming to the glass Telon, it coats one deck organic polymer thin film high temperature resistant, corrosion-resistant, that flexibility is good with the glass fibre outside surface and forms.
The New-type composite fibre of glass Telon of the present invention can be that long filament also can be short silk.
The organic polymer that the present invention is coated on glass heart yearn outside surface can be tetrafluoroethylene, polyimide or polybenzoxazoles.
Tetrafluoroethylene is a kind of high molecular synthetic material, and three kinds of granular, powdery and dispersion liquids are arranged.

It has remarkable resistance to chemical corrosion, and except that molten metal sodium and liquid fluorine, other all pharmaceutical chemicalss of ability boil also in chloroazotic acid and do not change.Its good heat resistance, minimum operating temperature-269 ℃; 250 ℃ of maximum operating temperatures.Polyimide is a thermoplastic resin, and its molecular structure is:
R is-O-in the formula,
-CH
2-wait gene.
It has outstanding resistance to elevated temperatures, can keep favorable mechanical performance and electrical property in-310～+ 343 ℃ scope 250～280 ℃ of following long term operations.Polyimide can be used as engineering plastics, also can be in order to make materials such as synthon, film, coating and tackiness agent.
Polybenzoxazoles is a kind of by 3, the high-temperature polymer that 3 '-dihydroxybiphenyl amine and a benzoyl chloride or the condensation of dioctyl phthalate phenyl ester form, and its molecular structure is:
Polybenzoxazoles has good thermotolerance and thermo-oxidative stability, can use under 400～500 ℃ of temperature.
Corresponding with the said products invention, the invention provides a kind of method that is used to make aforementioned glass Telon New-type composite fibre filamentary material, what comprise glass fibre is drawn into operations such as silk, lubricated, winding, unwinding, spinning, it is characterized in that drawing at glass fibre be added with coating in addition after being shaped, flood organic polymer thin film and heat fusing, the typing two procedures.
The present invention also provides a kind of method that is used to make the short wire material of aforementioned glass Telon New-type composite fibre, comprise glass fibre be drawn into silk, lubricated, twine, short cutting and operation such as spinning, it is characterized in that after glass fibre is drawn into silk, being added with in addition coating, flood organic polymer thin film and heat fusing two procedures.
Glass Telon advanced composite material of the present invention except that having the total resistance toheat of glass fibre and surface refractory organic polymer, also has the high-tensile of glass fibre heart yearn; Erosion resistance, flexibility and scratch-resistant performance with organic polymer.With glass Telon complex fiber material manufacturing high-temperature filter cloth provided by the present invention or Nomex, the range of application that not only can greatly widen sack cleaner; And can prolong work-ing life of fly-ash separator greatly.
