Abstract

The invention relates to a modified geogrid processed by using waste cross-linked polyethylene cable material. The modified geogrid is obtained by processing the following component raw materials in parts by weight: 30-40 parts of a waste cross-linked polyethylene cable material, 30-40 parts of styrene-maleic anhydride copolymer, 5-8 parts of a phosphate coupling agent, 30-40 parts of high-density polyethylene, 0.2-0.3 part of an anti-aging agent 168, 0.2-0.3 part of 2,4,6-tristertbutylphenol, 5-10 parts of a plasticizer DOP (Dioctyl-Phthalate), 1-2 parts of straw ashes, 8-10 parts of carbon black, 1-2 parts of sodium carboxymethyl cellulose, 6-10 parts of palygorskite clay and 15-20 parts of a modified filler. The modified geogrid is processed by using the waste cross-linked polyethylene cable material by virtue of the steps of mixing the materials in the formula, extruding, molding the melt through a three-roller calender to obtain a plate, punching the plate by a punching machine, heating the punched plate and then stretching to obtain the geogrid. The geogrid processed by the preparation method disclosed by the invention is low in cost of raw materials and has the effects that the waste is recycled and resources are saved and meanwhile, the product has the characteristics of high impact strength, large toughness and strong corrosion resistance.

Description

technical field [0001] The invention relates to the manufacture of geotechnical grids, in particular to a geotechnical grid processed and modified by waste cross-linked polyethylene cable materials and a preparation method thereof. Background technique [0002] With the development of the geosynthetics industry, more and more geogrid products have been introduced to the market. The main competition of geogrids is product performance and price and cost competition. Due to the wide range of fields and application areas of polypropylene geogrids, geogrids are required to have various properties. However, it is difficult to achieve these properties with only one polymer, so it is an inevitable trend in this industry to modify the geogrid formulation. Fiber reinforcement is a common and effective method in the preparation of high-performance materials, and the fibers used for reinforcement are generally glass fibers, carbon fibers, etc. The resin reinforcement effect obtained...
