Abstract

The invention discloses a flame-retardant oxidation-resistant geogrid. The flame-retardant oxidation-resistant geogrid consists of the following raw materials in parts by weight: 1-2 parts of benzyltriphenylphosphonium chloride, 10-17 parts of polypropylenimine, 6-8 parts of tert-butyl acrylate, 0.1-0.3 part of lithium aluminium hydride, 0.3-1 part of 4-dimethylaminopyridine, 0.4-1 part of an antioxidant 1010, 10-15 parts of multi-walled carbon nano tubes, 0.6-1 part of an antioxidant 168, 140-160 parts of high density polyethylene, 2-4 parts of hydrous zinc borate, 5-7 parts of dibutyl maleate, 10-13 parts of fumed silica, 0.2-0.4 part of beta-hydroxyalkylamide, 1-2 parts of polyoxyethylene alkyl ether, 2-3 parts of ammonium polyphosphate, 1-2 parts of aluminium stearate, and 0.3-1 part of stearamide. The benzyltriphenylphosphonium chloride, the hydrous zinc borate and the like is added into the flame-retardant oxidation-resistant geogrid, and therefore, flame-retardant property of a finished product is improved effectively.

Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to a flame-retardant 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...
