Rosin-containing geogrid

Abstract

The invention discloses a rosin-containing geogrid. The rosin-containing geogrid consists of the following raw materials in parts by weight: 107-120 parts of high-density polypropylene, 8-10 parts of carboxyl graphene powder, 0.1-0.2 part of cadmium stearate, 6-10 parts of maleic anhydride grafted polypropylene, 2-3 parts of rosin, 1-2 parts of lanolin, 0.1-0.3 part of potassium bromoflouride, 1-1.6 parts of dispersing agent NNO, 0.1-0.4 part of antioxidant BHT, 2-3 parts of bamboo carbon powder, 0.2-0.4 part of hexafluoro-acetylacetone, 7-10 parts of blast furnace slag, 2-3 parts of rare earth auxiliary and 1-2 parts of sodium silicate. The rare earth auxiliary added into the rosin containing geogrid is formed through the full mixing of high-strength boron carbide, attapulgite and rare earth elements, the cooperation of a calcium acetate antiseptic and a polyvinylpyrrolidone stabilizer and the surface treatment action of a silane coupling agent, so that the formed auxiliary is high in not only surface strength, tenacity, weatherability and corrosion resistance, but also stability. The comprehensive quality of the finished product can be effectively improved by the auxiliary, and the adaptability to soil and the resistance to external pressure are improved.

Description

technical field [0001] The invention mainly relates to the construction field, in particular to a geogrid containing rosin. 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, SiO2 and Al2O3. A lot of blast furnace slag waste is produced every year in my country. At present, it is widely used in roads, airports, foundation projects, railway ballast, Concrete aggregate and asphalt pavement, etc., but no blast furnace s...
