Highly tenacious nylon monofilament filter cloth modified by radiation grafting of nanocarbon sol and nanographite and preparation method thereof

Abstract

The invention discloses a highly tenacious nylon monofilament filter cloth modified by radiation grafting of nanocarbon sol and nanographite. The filter cloth comprises, by weight, 100-105 parts of nylon monofilament filter cloth, 3-3.5 parts of nanocarbon sol, 2.7-3 parts of nanographite, 0.8-0.9 part of FeSO4-7H2O, 24-26 parts of Trifluoroethyl acrylate, 1.2-1.5 parts of nano-hydroxyapatite, 3-3.5 parts of polyphenylene sulfide micron powder, 2.8-3.2 parts of flexible SiO2 nanofibers, 1.8-2.1 parts of triallyl Isocyanurate, 24-26 parts of dodecafluoroheptyl methacrylate and suitable amount of water. The invention uses nanocarbon sol to soak the nylon monofilement filter cloth, enhances the density, heat-resistance and friction-resistance of the filter cloth. Through the incorporation of polyphenylene sulfide micron powder to adsorb the nano-hydroxyapatite, enhances the tenacity and filtration precision of the filter cloth. The use of SiO2 nanofiber enhances the tenacity and anti-deformation property of the filter cloth.

Description

technical field [0001] The invention relates to the technical field of nylon filter cloth, in particular to a nylon monofilament filter cloth modified by radiation grafting of high-toughness nano-carbon sol and nano-graphite 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 sur...

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.
