Phosphorized polypropylene geogrid

Abstract

The invention discloses a phosphorized polypropylene geogrid. The phosphorized polypropylene geogrid comprises the following raw materials in parts by weight: 110-120 parts of high-density polypropylene, 2-3 parts of asphalt, 4-6 parts of scolecite, 1-2 parts of ammonium dihydrogen phosphate, 1-2 parts of potassium phosphate, 0.6-1 part of erucyl amide, 0.6-1 part of pentaerythritol, 0.1-0.3 part of 2, 4- imidazolidinone, 2-3 parts of trioctyl phosphate, 0.1-0.2 part of butyltin mercaptide, 6-10 parts of blast furnace slag, 7-10 parts of wollastonite powder, 0.4-1 part of sdium chloride, 2-3 parts of rare earth adjuvant and 1-2 parts of aluminum nitride powder. The rare earth adjuvant added into the phosphorized polypropylene geogrid can sufficiently mix high-strength boron carbide with attapulgite and rare earth elements, and together with a preservative calcium acetate and a stabilizer polyvinylpyrrolidone and through surface treatment of a silane coupling agent, the formed adjuvant not only has good surface strength, good toughness, excellent weather resistance, strong corrosion resistance and good stability, and can effectively improve the overall quality of a finished product and improve adaptability to soil and resistance to outside pressure.

Description

technical field [0001] The invention mainly relates to the construction field, in particular to a phosphated polypropylene geogrid. Background technique [0002] At present, the preparation of geogrid materials is relatively simple. Most of them are directly extruded with reinforcing agents such as high molecular polymers and carbon black. With the continuous development and progress of society, the research on soil environment, climate environment, etc. Or indirectly affect the on-site construction and post-effects, therefore, it is necessary to further improve the performance of the traditional simple geogrid; [0003] Blast furnace slag is the waste discharged from the blast furnace when smelting pig iron, the main components are CaO, SiO 2 、Al 2 o 3 , my country produces a lot of blast furnace slag waste every year, which is widely used in highways, airports, foundation projects, railway ballast, concrete aggregate and asphalt pavement, etc., but no blast furnace ...
