Problems solved by technology

However, after using glass fiber and carbon fiber, the tensile elongation of the polymer will be greatly reduced, resulting in a very short stretch of the geogrid, and an increase in the weight per unit area of ​​the product, which will increase the production cost instead, which is not conducive to achieving low cost. the goal of

Embodiment Construction

[0015] Below in conjunction with embodiment the present invention will be further described,

[0016] A styrene elastomer geogrid is processed from the following components by weight (kg): PP resin 75, and the styrene elastomer is styrene-butadiene-styrene block copolymer (SBS) 25, barium stearate 0.3, antioxidant 300 0.3, antioxidant 1076 0.15, ultraviolet absorber UV-9 0.2, modified filler 30,

[0017] Wherein, the preparation method of the modified filler: a, take the following component raw materials by weight: calcium carbonate 75, kaolin 15, sodium polyacrylate 0.4, white oil 2, antioxidant 1010 0.2, stearic acid 0.3, concentration is 14 % sodium hydroxide solution 45, Tween 80 0.2, barium stearate 3, aluminum hydroxide 5, triethanolamine borate 1.5; b. Add calcium carbonate and kaolin to the sodium hydroxide solution, Grind down for 20-30 minutes, then add sodium polyacrylate, white oil, stearic acid, continue grinding for 5-10 minutes, then add Tween 80, ba...

Abstract

The invention relates to a styrene elastomer geogrid prepared by processing the following raw materials in parts by weight: 70-80 parts of PP resin, 20-30 parts of styrene elastomers, 0.2-0.4 part of barium stearate, 0.2-0.4 part of antioxidant 300, 0.1-0.2 part of antioxidant 1076, 0.1-0.3 part of ultraviolet absorbent UV-9 and 25-35 parts of modified filler. The preparation method of the styrene elastomer geogrid comprises the steps of mixing all the materials in the formula, and extruding to obtain a melt; forming a plate from the melt by using a three-roll calendar; punching the plate by using a punching machine; and stretching after heating the pore plate to obtain the geogrid. The modified geogrid prepared by processing the raw materials is high in stretching strength, corrosion-resistant, good in mechanical properties and low in production and processing costs.

Description

technical field [0001] The invention relates to the manufacture of geogrids, in particular to a styrene elastomer geogrid and a preparation method. 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 by filling these fibers is obvious, which can make the geogrid of the same size thi...
