Multifunctional macromolecule filter material and preparation method thereof

Abstract

The invention relates to a multifunctional polymer filtering material which comprises 70 to 85 percent of glass fiber, the balance being one or a plurality of aramid, polytetrafluoroethylene (PTFE) fiber, polyphenylene sulfide fiber, poly (p-phenylene-benzobisoxazole) (PBO) fiber, p-aramid, ceramic fiber, stainless steel fiber and copper fiber. The invention also discloses a method for preparing the multifunctional polymer filtering material. The method comprises the following steps: mixing the 70 to 85 percent of glass fiber and at least one of aramid, polytetrafluoroethylene (PTFE) fiber, polyphenylene sulfide fiber, poly (p-phenylene-benzobisoxazole) (PBO) fiber, para-aramid, ceramic fiber, stainless steel fiber, copper fiber into a synthetic fabric; and puncturing and shaping the synthetic fabric and a base fabric to obtain a finished product. The filtrating material produced by the method has the advantages of low cost, water proofing, temperature resistance, corrosion resistance and high performance to price ratio.

Description

technical field [0001] The invention relates to a polymer material, in particular to a multifunctional polymer filter material and a preparation method thereof. Background technique [0002] The current filter materials mainly use fibers such as polyester, polypropylene, polyphenylene sulfide and polytetraethylene as raw materials. Generally, they are produced and processed by weaving and needle punching. Because of the waterproof, temperature resistance and corrosion resistance of various fibers , The price of raw materials and the difficulty of processing are different, resulting in an increase in the cost difference of the produced filter cloth. For example, the raw material cost of polytetrafluoroethylene fibers is 20 to 30 times that of polyester fibers, and polytetrafluoroethylene fibers are prone to entanglement and static electricity during processing, resulting in reduced output and increased production costs in disguise , resulting in a relatively high price for i...

For example, the raw material cost of polytetrafluoroethylene fibers is 20 to 30 times that of polyester fibers, and polytetrafluoroethylene fibers are prone to entanglement and static electricity during processing, resulting in reduced output and increased production costs in disguise , resulting in a relatively high price for its finished product

[0003] Due to the gradual increase in environmental protection requirements in my country in recent years, some high-temperature environments and environments with harsh acid-base levels or large water vapor components in the past were often solved by electrostatic dust removal, but the dust removal efficiency can only reach 95% and cannot meet the current requirements. Therefore, there is an urgent need to develop a filter material with composite properties that is resistant to high temperatures, can be used in an environment with certain acid-base components or water vapor components, and is in line with my country's economic and national conditions.
