Abstract

The invention discloses an anti-oxidation polymer geogrid. The anti-oxidation polymer geogrid is prepared from, by weight, 0.7-1 part of hexamethylphosphoramide, 10-17 parts of polypropyleneimine, 6-8 parts of tert-butyl acrylate, 0.1-0.3 part of lithium aluminum hydride, 0.3-1 part of 4-dimethylaminopyridine, 0.4-1 part of an antioxidant 1010, 10-15 parts of multiwalled carbon nanotubes, 0.6-1 part of an antioxidant 168, 140-160 parts of high-density polyethylene, 2-3 parts of sodium myristate, 0.1-0.4 part of dithiosalicylic acid, 1-2 parts of tri(nonylphenyl)phosphate, 0.8-2 parts of cetyl trimethyl ammonium bromide, 2-3 parts of alkyl ketene dimers, 0.6-1 part of butylmercaptooxo-stannane and 10-16 parts of graphite powder. Multiple polymers are added, and thus the surface resistance of the finished product can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to a polymer anti-oxidation geogrid and a preparation method thereof. Background technique [0002] As a typical one-dimensional nanomaterial, carbon nanotubes have a large aspect ratio, ultra-high elastic modulus and bending strength, unique electrical conductivity, excellent thermal conductivity, and strong acid resistance compared with traditional fillers. , strong alkali and other advantages. Studies have shown that by combining carbon nanotubes and polyolefins to fully combine their respective properties, a multifunctional polyolefin / carbon nanotube composite material with excellent mechanical, electrical conductivity, and flame-retardant properties can be prepared. The potential huge advantages of polyolefin / carbon nanotube composite materials have attracted extensive attention from researchers at home and abroad; [0003] Although compared with ordinary polymer materials, ...
