High-strength nano carbon sol, nano graphite irradiation grafting modified polyamide monofilament filter cloth, and preparation method thereof

Abstract

The invention discloses a high-strength nano carbon sol, nano graphite irradiation grafting modified polyamide monofilament filter cloth. The high-strength nano carbon sol, nano graphite irradiation grafting modified polyamide monofilament filter cloth is prepared from, by weight, 100 to 105 parts of polyamide monofilament filter cloth, 3 to 3.5 parts of nano carbon sol, 2.7 to 3 parts of nano graphite, 0.8 to 0.9 part of FeSO4-7H2O, 24 to 26 parts of trifluoroethyl acrylate, 1.7 to 2 parts of carbon nanotube, 2 to 2.5 parts of active carbon fiber, 1.3 to 1.5 parts of silver nitrate, 1.5 to 1.8 parts of glucose, 24 to 26 parts of dodecafluoroheptyl methacrylate, and an appropriate amount of water. According to the preparation method, the strength and adsorptive property of filter cloth coated film are improved via adding of carbon nanotube and active carbon fiber, and filtering precision is increased; modification with silver nitrate and glucose is carried out, and carbon nanotube and active carbon fiber are loaded with silver particles, so that the obtained filter cloth is provided with antibacterial performance, and pore blocking caused by bacteria breeding is reduced.

Description

technical field [0001] The invention relates to the technical field of nylon filter cloth, in particular to a high-strength nano-carbon sol and 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 ...

AI Technical Summary

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.
