Abstract

The invention discloses a geogrid resistant to heat and humidity, which is composed of the following raw materials in parts by weight: zinc dihydrogen phosphate 4-5, phosphite 2-3, dimethyl diallyl chloride Ammonium 0.6‑1, polypropylene imine 10‑17, tert-butyl acrylate 6‑8, 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, high-density polyethylene 140-160, chlorinated paraffin 4-6, titanium dioxide 10-12, butyltin trioctoate 0.4-1, amino trimethylene phosphonic acid 0.1-0.2, di Phenylsilanediol 2‑3, calcium hexafluoroacetylacetonate 0.4‑1. The geogrid of the invention has good resistance to heat and humidity, good impermeability, and is not easy to corrode.

Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to a heat-resistant and 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 ...
