Abstract

The invention discloses an anti-oxidation rare-earth geogrid. The anti-oxidation rare-earth geogrid comprises, by weight, 0.01-0.04 part of lanthanum citrate, 4-6 parts of dioctyl sebacate, 0.1-0.3 part of 8-hydroxyquinoline, 1-2 parts of aluminum potassium sulfate, 10-17 parts of poly propylene imine, 6-8 parts of tert-butyl acrylate, 0.1-0.3 part of lithium aluminum hydride, 0.3-1 part of dimethylamino pyridine, 0.4-1 part of antioxidant 1010, 10-15 parts of multiwalled carbon nanotube, 0.6-1 part of antioxidant 168, 140-160 parts of high-density polyethylene, 0.6-1 part of hexamethylphosphoric triamide, 1-2 parts of molybdenum boride, 0.7-1 part of triethanolamine borate, 10-14 parts of illite powder and 0.3-0.5 part of hexabromocyclododecane. By the preparation method of the anti-oxidation rare-earth geogrid, the content of free radicals participating in polymer auto-oxidation chain reaction is lowered greatly, the polymer oxidation and degradation are delayed, and the anti-oxidation performance of the finished material is increased.

Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to a rare earth 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 material...
