Graphene composite PP fibers and preparation method thereof

Abstract

The invention belongs to the field of preparation of composite fibers and particularly relates to graphene composite PP fibers and a preparation method thereof. The graphene composite PP fibers comprise the following matters: grapheme, sodium polyacrylate, a cationic surface active agent, a filler, microcrystalline celluloses, a solvent, silica gel and plant polyphenol, wherein the filler is one of or a variety of or any quality ratio of aluminum oxide, aluminum powder, titanium dioxide or pyrophyllite powder; the solvent is ethanol or acetone; the grapheme is 3-10 layers of grapheme. The graphene composite PP fibers and the preparation method thereof provided by the invention have the benefit that the comprehensive performance of the PP fiber is effectively improved.

Description

technical field [0001] The invention belongs to the field of composite fiber preparation, and in particular relates to a graphene composite PP fiber and a preparation method. Background technique [0002] PP (polypropylene) fiber has light weight, high strength, good elasticity, wear resistance, corrosion resistance, electrical insulation and warmth retention, and occupies a large market in the field of fiber application. However, polypropylene fiber has high resistivity (7×10Ω.cm) and low thermal conductivity. Compared with other chemical fibers, polypropylene fiber has the best electrical insulation and warmth retention, but it is prone to static electricity during processing; and polypropylene fiber has the best electrical insulation and warmth retention properties. Low melting point (165~173°C), poor stability to light and heat. [0003] In the prior art, in order to expand the application range of PP fibers, the comprehensive properties of PP fibers are usually changed...

Problems solved by technology

However, there will be the following problems in its specific application. One is the dispersion of the added inorganic fillers. Different sizes of inorganic fillers have a more obvious effect on the performance of polymers. Generally, the smaller the particle size (inorganic fillers), the better the performance of polymers. However, if the filler is too small, there will be a problem of agglomeration, and once the inorganic filler is agglomerated in the fiber, the toughness of the fiber agglomeration will be extremely poor; the second is the control of the amount of inorganic filler added, if the addition is too small, the fiber cannot be improved The performance of the fiber; adding too much will affect the performance of the fiber itself; how to effectively add inorganic fillers to effectively improve the comprehensive performance of the fiber is a research hotspot
