Anti-oxidation rare-earth geogrid and preparation method thereof

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...

Problems solved by technology

[0004] Although carbon nanotubes have many excellent properties, their applications are greatly limited due to their poor solubility in water and organic solvents, poor dispersion in the polymer matrix, and poor compatibility with the matrix. Effect
