Abstract

The invention discloses a lightweight anti-oxidation geogrid, which is composed of the following raw materials in parts by weight: polypropyleneimine 10-17, tert-butyl acrylate 6-8, lithium aluminum hydride 0.1-0.3, 4 ‑Dimethylaminopyridine 0.3‑1, Antioxidant 10100.4‑1, Multiwalled Carbon Nanotubes 10‑15, Antioxidant 1680.6‑1, High Density Polyethylene 140‑160, Dioctyl Dimethyl Ammonium Chloride 1 ‑2, diacetone alcohol 2‑3, dimethylaminopropylamine 0.5‑1, light calcium carbonate 10‑15, isooctyl methacrylate 4‑6, petroleum sodium sulfonate 0.8‑1, hydrolyzed polymaleic anhydride 2 ‑3. Trimethylolpropane 0.1‑0.2. 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 geogrid, in particular to a lightweight anti-oxidation geogrid and a preparation method thereof. Background technique [0002] As a typical one-dimensional nanomaterial, carbon nanotubes have a great aspect ratio, ultra-high elastic modulus and bending strength compared with traditional fillers, peculiar electrical conductivity, excellent thermal conductivity, and strong acid resistance , Strong alkali and other advantages. Studies have shown that by combining carbon nanotubes with polyolefins to fully combine their 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 wide attention from domestic and foreign researchers; [0003] Although compared to ordinary polymer materials, polyolefin / carbon ...
