Abstract

The invention relates to a high-strength anti-aging warp knitting complex geotextile as well as a preparation method of an anti-aging layer thereof. The complex geotextile comprises a knitting geotextile at the upper layer and a non-woven layer at the lower layer, wherein the knitting geotextile and the non-woven layer are connected through dacron connecting yarns; the anti-aging layer is coated on the outer surface of the complex geotextile. The complex geotextile has the characteristics of good puncture resistance, high strength, large modulus, low extensibility, and the like, has better ageing resistance and abrasive resistance, and is capable of improving the stability and the safety of engineering such as refuse landfills, mines, reservoirs and traffic.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a composite geotextile, in particular to a preparation method of a high-strength anti-aging warp-knitted composite geotextile and an anti-aging layer. Background technique [0002] Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving, and the finished product is cloth-like. [0003] Geotextiles have excellent functions of filtration, drainage, isolation, reinforcement, anti-seepage, and protection. They are light in weight, high in tensile strength, good in permeability, high temperature resistance, freezing resistance, aging resistance, and corrosion resistance. Geotextiles are divided into woven geotextiles and non-woven geotextiles. At present, geotextiles are mainly used in water conservancy, ports, waterways, railways, highways and other projects with small sediment diameters and large forces. ...
