Problems solved by technology

[0003] However, the existing commonly used geotextiles have a single structure, low tensile strength and deformation resistance, and shorten the life of the geotextiles. Therefore, those skilled in the art urgently need to provide a reinforced geotextile that can effectively increase the tensile strength. And anti-deformation ability, prolong the service life of geotextile

Abstract

The invention relates to a high-performance non-slip geotextile and a preparation method thereof. The geotextile includes a base layer and a bottom layer; the base layer is woven from warp threads and weft threads; the bottom layer includes polyimide fibers, glass fibers and high-strength fibers , after opening, mixing, carding and laying, the three kinds of fibers are interwoven together by acupuncture and heat setting; the weight ratio of polyimide fiber, glass fiber and high-strength fiber is 4:4:2, and the base layer Anti-slip dots are provided on the upper surface and the bottom of the bottom layer. The geotextile has excellent mechanical properties, strong tensile strength and deformation resistance, and good corrosion resistance. It plays the role of reinforcement, anti-seepage, and anti-reflection cracks in the reconstruction of the road surface, and can further prolong the service life of the road surface.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a geotextile and a preparation method thereof, in particular to a high-performance anti-slip geotextile and a preparation method thereof. Background technique [0002] At present, geotextiles are mainly used in water conservancy, ports, waterways, railways, highways and other projects with small sediment diameters and large forces. The material is not mixed and the integrity of the material is maintained; 2: Filtration function, when water flows from the fine material soil layer into the coarse material soil layer, the water permeability of the geotextile is used to allow water to pass through and intercept soil particles, fine sand and other materials; 3: Stabilization, enhance the tensile and deformation resistance of the soil, and enhance the stability of the building structure. [0003] However, the existing commonly used geotextiles have a single structure, low tensile stren...
