Description
Technical field
The present invention relates to the preparation method of composite filtering material, particularly relate to a kind of preparation method of treated basalt fiber/polyphenylene sulfide composite filtering material dip coated.
Background technology
At present, fire resistant filter material has been widely used in industrial circles such as generating, cement, and filtrate is the chief component of gas-solid separating device, and its performance directly determines the quality of filter effect.In order to improve filtering accuracy, people are except constantly improving aborning the preparation technology of filtrate own, also use the rear finishing techniques such as dipping, coating and overlay film, be intended to improve top layer and the internal structure of filter material, thereby obtain the high efficiency filter material of even structure, dimensionally stable.
In actual production, find, the oxidative resistance of single polyphenylene sulfide Nomex is bad, cannot adapt to the clean-up effect under high oxygen condition.Although single polytetrafluoroethylene fibre Nomex has water repellency, oxidation resistent susceptibility, it is expensive, also very high to equipment for after-treatment requirement, increases production cost.
Along with the raising that media performance is required, the application of composite filtering material is also more and more extensive, by the research to basalt fibre, finds, high temperature resistant, anti-oxidant and radiation-resistant feature that basalt fibre has can be widely used in filtrate and produce.Basalt fibre/the polyphenylene sulfide of take is manufactured compound filter cloth as base cloth and can effectively be improved the dimensional stability being compounded with under material at high temperature, also can improve its acid-fast alkali-proof simultaneously.But in actual machine-shaping process, the polyphenylene sulfide of fibre-grade exists that spinning temperature is high, melt viscosity is high, the shortcoming of poor mobile performance, product color is darker, wiriness.
In sum, at present in the urgent need to a kind of preparation method of composite filtering material, can improve composite filtering material high-temperature stability, improve its acid-fast alkali-proof and promote that composite merges mutually, thereby improve the strainability of finished product.
Summary of the invention
Hyperbranched polyphenylene sulfide has the chemical composition similar with linear polyphenylthioether, all contains phenyl ring and sulphur atom, but chemical constitution is different.By the blend according to a certain ratio of the polyphenylene sulfide of hyperbranched polyphenylene sulfide and line style, can, when reducing melt viscosity, improving end properties, keep both good compatibilities.For solving the problems of the technologies described above, this method provides a kind of preparation method of treated basalt fiber/polyphenylene sulfide composite filtering material dip coated.By adding hyperbranched polyphenylene sulfide, prepare treated basalt fiber/polyphenylene sulfide composite filtering material, between the high-temperature stability of raising composite filtering material, acid-fast alkali-proof, promotion composite bed, mutually combine, and improve dispersiveness and the compactness extent of fiber.
For achieving the above object, technical scheme provided by the present invention is:
