Abstract
The present invention relates to a kind of preparation method of high-strength anti-aging warp knit composite earthwork cloth and its anti-aging layer, composite earthwork cloth includes the braided geotextile layer and the nonwoven layer of lower floor on upper strata, braided geotextile layer is connected with nonwoven layer by terylene connecting line, and the outer surface of composite earthwork cloth is coated with anti-aging layer.Composite earthwork cloth has that penetration-resistant can good, intensity be high, modulus is big, the low feature of ductility and preferably ageing resistance and wearability, can improve the stability and security of the engineerings such as refuse landfill, mine, reservoir, traffic.
Description
Technical field
The invention belongs to building materials field, it is related to a kind of composite earthwork cloth, is passed through in particular to a kind of high-strength and ageing resistance
Compile the preparation method of composite earthwork cloth and anti-aging layer.
Background technology
Geotextiles, also known as geotextile, it is to be closed by synthetic fibers by the water penetration geotechnique of acupuncture or braiding
Into material, finished product is cloth-like.
Geotextiles have outstanding filtering, draining, isolation, reinforcement, antiseepage, protective action, with lightweight, tensile strength
It is height, good penetrability, high temperature resistant, anti-freezing, ageing-resistant, corrosion-resistant.Geotextiles are divided into Woven geofabric and non-woven geotextile.Mesh
Before, geotextiles are mainly used in the big engineering of the small stress of the silt diameter such as water conservancy, harbour, navigation channel, railway, highway, what it was played
Main function includes 1：Buffer action, isolates to the construction material of different physical properties, material is not mixed, and keeps material
Globality；2：Filtration, when water flows into coarse fodder soil layer by fines soil layer, using the water penetration of geotextiles, allows water to pass through
And intercept the materials such as soil particle, fine sand；3：Stabilization, strengthens soil body tension non-deformability, and enhancing building structure is stable
Property.Existing warp knit composite earthwork cloth fine or long filament geotextiles performance short compared to tradition is more excellent.
But its structure and material are more single, service life is short, is difficult still the requirement for meeting engineering design.Mainly
It is due to the following reasons：(1) it is only made up of lower nonwoven fabric layer and upper strata warp knit layer, is connected between levels using polyester thread
Connect.Lower nonwoven cloth typically uses polyester or polypropene staple needle punched non-woven fabrics, and grammes per square metre is 120g/m2, it is strongly low, wear well
Pierce ability, it is easy to punctured by the sharp objects in the soil body.Upper strata warp knit layer is using polyester, glass or ageing resistance polypropylene
Every monofilament is very thin in synnema, synnema, diameter be about strength between ten a few to tens of microns, every monofilament it is irregular compared with
Greatly, in construction and application process, it may appear that the phenomenon of monofilaments wear fracture, so as to cause the every mechanical property of warp knit geotextiles
Decline；(2) existing warp knit geotextiles lack anti-aging layer, and in used conventional material, polyester fiber it is acidproof intolerant to
Alkali, polypropylene fibre (including ageing resistance polypropylene fiber) ultraviolet resistance aging are poor, acid-base waste fluid, metal ion, ultraviolet light
Presence etc. factor can accelerate the aging of warp knit geotextiles, so as to influence the security and stability of engineering.Therefore, existing warp knit soil
Work cloth ageing-resistant performance is poor, influences its service life.
Therefore, those skilled in the art need a kind of high-strength anti-aging warp knit composite earthwork cloth of offer badly, improve its anti-puncture
And wear resistance, strengthen ageing-resistant performance, be still an extremely urgent task.
The content of the invention
The purpose of the present invention is to overcome existing warp knit composite earthwork cloth to be easily punctured, easy to wear, the problem of easy aging, this
Invention provides a kind of high-strength and ageing resistance warp knit composite earthwork cloth.
The present invention is for the technical scheme that is used of solution above-mentioned technical problem：A kind of high-strength and ageing resistance warp knit composite earth
Work cloth, the braided geotextile layer and the nonwoven layer of lower floor of the composite earthwork cloth including upper strata, the braided geotextile layer and
The nonwoven layer is connected by terylene connecting line, and the nonwoven layer is made up of chopped fiber, and the braided geotextile layer is
It is made up of monfil, the Surface coating of the every chopped fiber and the every monfil has anti-aging layer.
Specifically, the anti-aging layer is polymer-based nano hybridized film.
Specifically, the raw material that the polymer-based nano hybridized film is used is nano silicon and flourine-containing acrylate ester.
Specifically, the specific surface area of the nano silicon is 200 ± 25m2/ g, average grain diameter is 12nm.Nanometer two
Silica is to be hydrolyzed to be made in oxyhydrogen flame by chlorosilane, and its particle size is identical with the wavelength size of ultraviolet light, Ke Yiyou
Effect ground absorbs and light reflection ultraviolet, slows down the aging of composite earthwork cloth, extends the service life of composite earthwork cloth.
Specifically, the flourine-containing acrylate ester refers to flourine-containing acrylate ester emulsion, the property of the flourine-containing acrylate ester emulsion
Matter is as follows：Solid content is that 42 ± 1%, Ph values are 7.5~8.5, and fluorinated volume is 9%, and average grain diameter is about 0.1 μm, the fluorine carbon
