Abstract

The invention discloses a carbon nanotube reinforced anti-oxidation geogrid, which is composed of the following raw materials in parts by weight: 1.6-2 calcium acetylacetonate, 0.7-1 alkenyl succinic anhydride, and 1-2 barium stearate , lithium aluminum hydride 0.1‑0.3, 4‑dimethylaminopyridine 0.3‑1, antioxidant 10100.4‑1, multi-walled carbon nanotubes 10‑15, antioxidant 1680.6‑1, polypropylene imine 10‑17, acrylic acid Tert-butyl ester 6-8, high-density polyethylene 140-160, bisphenol a diglycidyl ether 0.3-1, 2-mercaptobenzimidazole 0.6-1, dibutyl maleate 4-6, cycloalkane Lithium Oxide 0.4‑1. The invention greatly reduces the content of free radicals participating in the automatic oxidation chain reaction of polymers, delays the oxidation degradation process of polymers, and improves the oxidation resistance of finished materials.

Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to a carbon nanotube-reinforced 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 ...
