Abstract

The invention discloses a polyethylene antioxidation geogrid which is composed of, by weight, 0.3-1 part of methyl triethoxysilane, 1-2 parts of zinc ricinate, 10-17 parts of polypropylene imine, 6-8 parts of tert-butyl acrylate, 0.1-0.3 part of aluminum lithium hydride, 0.3-1 part of 4-dimethylamino pyridine, 0.4-1 part of an antioxidant 101, 10-15 parts of multi-walled carbon nanotube, 0.6-1 part of an antioxidant 168, 140-160 parts of high-density polyethylene, 0.7-1 part of polyaspartic acid, 1-2 parts of ammonium octamolybdate, 3-4 parts of carboxylic acid glyceride, 0.1-0.2 part of polyglycerol-10 oleate, 0.1-0.3 part of 2-mercapto benzimidazole, 10-14 parts of diatomite and 2-3 parts of aluminum dihydrogen phosphate. The polyethylene antioxidation geogrid is high in hydrophobicity, impact resistance and tenacity and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to a polyethylene 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 materi...
