Anti-static, oil-stain, and corrosion-resistant environmental protection filter material and preparation method thereof

Abstract

The invention discloses an anti-static environment-friendly filtering material with resistance to oil stain and corrosion and a preparation method of the filtering material. The filtering material comprises textile fabric, FMS needle felts needled on upper and lower surfaces of the textile fabric and chemical films covering the surfaces of the FMS needle felts, wherein the textile fabric is obtained from polyphenylene sulfide filaments by blending, polyimide filaments, aromatic polysulfone amide filaments and glass filaments; surfaces of the aromatic polysulfone amide filaments and the glass filaments are subjected to dipping treatment in a polyurethane solution; surfaces of the polyphenylene sulfide filaments and the polyimide filaments are subjected to dipping treatment in a polytetrafluoroethylene solution. The anti-static environment-friendly filtering material is reasonable in structural design, good in filtering performance and long in service life and has excellent combination properties including anti-static performance, oil stain and corrosion resistance, high tensile resistance and the like. The preparation method of the anti-static environment-friendly filtering material with resistance to oil stain and corrosion has the advantages of reasonable process design, high operability, low energy consumption, high environment friendliness and high production and working efficiency, and industrial production can be realized.

Description

technical field [0001] The invention relates to an environmental protection filter material, in particular to an environmental protection filter material with strong environmental protection, good filtration performance, corrosion resistance, high temperature resistance, strong tensile resistance, antistatic, oil stain and corrosion resistance, and a preparation method thereof, which belongs to environmental protection technology field. Background technique [0002] In steel, cement, petrochemical, liquid bed boilers, coal-fired boilers, calcium carbide plants, and precision instrument processing industries, dust or smoke must be filtered and dedusted during the production process, but the existing filter materials are anti-static and oil-resistant And the corrosion resistance is weak, the filtering effect is poor, and the service life is short, and the durability is poor. [0003] In addition, in the prior art, the properties of single fiber textile fabrics are not compreh...

Problems solved by technology

[0002] In steel, cement, petrochemical, liquid bed boilers, coal-fired boilers, calcium carbide plants, and precision instrument processing industries, dust or smoke must be filtered and dedusted during the production process, but the existing filter materials are anti-static and oil-resistant And corrosion resistance is weak, the filtering effect is poor, and the service life is short, and the durability is poor

[0003] In addition, the performance of the textile fabric of a single fiber in the prior art is not comprehensive, such as maintaining good tensile strength and abrasion resistance, low elastic modulus, and insufficient antistatic oil repellency.
