Embodiment Construction

[0013] The best embodiment formula is:

[0014] 1. Acrylate 5%

[0015] 2. Modified starch 10%

[0016] 3. Light calcium carbonate 5%

[0017] 4. Isotactic polypropylene resin 75%

[0018] 5. UV stabilizer 2%

[0019] 6. Other additives 3%

[0020] This polypropylene spun-bonded needle-punched geotextile adopts the spun-bonded needle-punched process, after adding coagulants, ultraviolet stabilizers, cold-resistant agents and other modifiers to the polypropylene raw materials to improve the interfacial contact between the fibers of the needle-punched fabric. The cohesion force and the comprehensive performance of the finished product, the specific process is: add the modified polypropylene resin into the extruder, and then pass through the spinning box in turn, side blowing cooling, air drafting, spinning and laying, acupuncture Machine acupuncture reinforcement, heat setting machine, cloth storage machine, trimming and rolling, inspecti...

Abstract

The invention relates to a polypropylene fiber spunbond needle-punched geotextile, which belongs to a high-molecular geotechnical synthetic material. The polypropylene fiber spunbond needle-punched geotextile is produced by using modified polypropylene resin, adding cohesive agent, ultraviolet stabilizer and anti-freezing agent modifier for modification and by adopting a spunbond method and a needle-punching reinforcement process. The geotextile has the advantages of extremely high mechanical performance, strong chemical erosion resistance, good water guide performance and low material cost.

Description

technical field [0001] The invention belongs to a polymer geosynthetic material, in particular to a polypropylene spun-bonded needle-punched geotextile specially used for landfill plants. Background technique [0002] Geotextiles have been widely used in my country's geotechnical engineering, civil engineering, and water conservancy projects since the 1980s, among which polyester filament spunbonded needle-punched geotextiles and polyester staple fiber needle-punched geotextiles have been widely promoted and applied. Such as landfills, reservoirs, roads, railways, reclamation projects have been well promoted and so on. However, polypropylene products, whether polypropylene staple fiber geotextiles or polypropylene spunbonded needle-punched geotextiles, have not been effectively promoted and applied. Compared with polypropylene products of the same grammage and polyester products, the physical and mechanical properties of polypropylene are better than polyester products, such...
