Example Embodiment

[0017] An anti-ultraviolet nano carbon sol, nano graphite radiation graft modified nylon monofilament filter cloth, made of the following parts by weight (kg) of raw materials: nylon monofilament filter cloth 100, nano carbon sol 3, nano graphite 2.7, FeSO 4 ∙7H 2 O 0.8, trifluoroethyl acrylate 24, nano zinc oxide 1.6, nano titanium sol 2.8, nano barium sulfate 1.8, dodecafluoroheptyl methacrylate 24, an appropriate amount of water.

[0018] The preparation method of the anti-ultraviolet nano carbon sol and nano graphite radiation graft modified nylon monofilament filter cloth includes the following steps:

[0019] (1) Mix the nano carbon sol with water to prepare a dispersion with a concentration of 1% by mass. Put the nylon monofilament filter cloth into the dispersion and soak for 20 minutes. During this time, stir the nylon monofilament filter cloth and take it out for drying. Put it into a ziplock bag, perform pre-irradiation, the absorbed dose is 42kGy, and obtain a modified ...

Abstract

The invention discloses a UV-resistant nano carbon sol/nano graphite irradiation grafting modified nylon filament filter cloth, which is prepared from the following raw materials in parts by weight: 100 to 105 parts of nylon filament 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, 1.6 to 1.8 parts of nano zinc oxide, 2.8 to 3.2 parts of nano titanium sol, 1.8 to 2.1 parts of nano barium sulfate, 24 to 26 parts of dodecafluoroheptyl methacrylate, and a proper amount of water. The nylon filament filter cloth is impregnated in nano carbon sol, and the compactness, heatproof performance, wear resistant performance, and filter fineness of the filter cloth are all enhanced. Nano zinc oxide, nano titanium sol, and nano barium sulfate are mixed and grinded, nano titanium sol wraps nano zinc oxide and nano barium sulfate, the dispersibility is improved, and through the combination of nano zinc oxide, nano titanium sol, and nano barium sulfate, the UV resistant performance, wear resistant performance, and aging resistant performance of nylon are all strengthened.

Description

technical field [0001] The invention relates to the technical field of nylon filter cloth, in particular to an anti-ultraviolet 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...
