Antistatic nano-carbon sol and nano-graphite irradiation grafting modified nylon single-filament filtration cloth and preparation method thereof

Abstract

The invention discloses an antistatic nano-carbon sol and nano-graphite irradiation grafting modified nylon single-filament filtration cloth, which is prepared from the following raw materials by weight: 100-105 parts of a nylon single-filament filtration cloth, 3-3.5 parts of a nano-carbon sol, 2.7-3 parts of nano-graphite, 0.8-0.9 part of FeSO4.7H2O, 24-26 parts of trifluoroethyl acrylate, 1.6-1.8 parts of nanometer stannous oxide, 2.8-3.2 parts of indium oxide nanometer ceramic fiber, 1.8-2.1 parts of triallyl isocyanurate, 24-26 parts of dodecafluoroheptyl methacrylate, and a proper amount of water. According to the present invention, the nylon single-filament filtration cloth is impregnated with the nano-carbon sol so as to improve the compactness, the heat resistance and the wear resistance of the filtration cloth and increase the filtration precision; and by carrying out mixing grinding on nanometer stannous oxide, indium oxide nanometer ceramic fiber and triallyl isocyanurate, the filtration cloth has advantages of excellent antistatic effect, improved wear resistance, improved deformation resistance, and improved filtration precision.

Description

technical field [0001] The invention relates to the technical field of nylon filter cloth, in particular to an antistatic nano-carbon sol, nano-graphite irradiation graft modified nylon monofilament filter cloth and a preparation method thereof. Background technique [0002] The article "Research Progress of Monofilament Filter Cloth and Its Properties" introduces the properties of polyester, nylon, polypropylene and polyethylene monofilament filter cloths. Monofilament filter cloth refers to a filter cloth woven from a single fiber. Conventional monofilament filter cloth is generally woven from monofilament fibers such as nylon, polyester, polypropylene and polyethylene. Compared with multifilament filter cloth, monofilament filter cloth has high fiber strength and good toughness, and there will be no broken filaments during use; after adopting the calendering process, it has high stability, is not easy to deform, and has a dense and uniform pore size; The surface is smoot...

Problems solved by technology

[0007] "Hydrophilic Properties of Irradiation Grafted Modified Polyester Fabrics" provides radiation grafted modified polyester monofilament filter cloth, which can also be used to improve the water absorption rate. Poor stability of filter cloth size

It is also necessary to improve the loose structure of nylon filter cloth, poor elasticity, poor stain resistance and high temperature resistance, and the problem that the filter cake is not easy to peel off.
