Abstract

The invention discloses a titanium sol modified geogrid, which is composed of the following raw materials in parts by weight: aluminum nitride powder 2-3, 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, lignin Sodium sulfonate 1‑2, butyl benzyl phthalate 4‑7, dibasic lead phosphite 0.04‑0.1, triethanolamine 1‑2, microcrystalline paraffin 3‑4, silane coupling agent kh5600.6‑1 , Tetrabutyl titanate 3‑4. The combination of antioxidant 1010 and antioxidant 168 added in the present invention can eliminate alkyl free radicals, peroxyl free radicals, alkoxyl free radicals and hydroperoxides, and greatly reduce the freedom to participate in polymer autooxidation chain reactions. The base content can delay the oxidative degradation process of the polymer and improve the oxidation resistance of the finished material.

Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to a titanium sol modified 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, p...
