Description
Technical field
The present invention relates to architectural engineering earth working material technical field, and in particular to a kind of compound maintenance geotextiles of macromolecule
And preparation method thereof.
Background technology
At present, geotextiles are mainly used in water conservancy, harbour, navigation channel, railway, public affairs as the indispensable material of architectural engineering
The big engineering of the small stress of silt diameter such as road, its main function played includes：Different physical properties are built by the 1st, buffer action
Build material to be isolated, material is not mixed, keep the globality of material；2nd, filtration, when water is flowed into slightly by fines soil layer
Expect soil layer when, using the water penetration of geotextiles, allow water by and intercept the materials such as soil particle, fine sand；3rd, stabilization, enhancing soil
Body tension non-deformability, strengthens building structure stability.
Specifically, anti-seepage geotextile is also known as composite geo-membrane, be using plastic sheeting as antiseepage base material, it is and non-woven fabric compounded
Seepage by geo-textile material, its barrier performance depends primarily on the barrier performance of plastic sheeting.At present, domestic and international antiseepage should
Plastic sheeting, mainly there is polyvinylchloride and polythene PE, and they are a kind of polymer chemistry flexible materials, proportion compared with
Small, extensibility is stronger, adapts to deformability height, corrosion-resistant, low temperature resistant, good frost resistance.And non-woven fabrics is also a kind of macromolecule
Chopped fiber chemical material, by acupuncture or hot sticky shaping, with higher tensile strength and extensibility, it is combined with plastic sheeting
Afterwards, the tensile strength and puncture resistant ability of plastic sheeting are not only increased, and because nonwoven surface is coarse, increases contact
The coefficient of friction in face, is conducive to the stabilization of composite geo-membrane and protective layer.Meanwhile, they have preferably to bacterium and chemical action
Erosion resisting, has good effect in acid, the erosion of alkali, salt.Exactly because anti-seepage geotextile has superior water penetration, filterability, durable
Property, thus it can be widely used for railway, highway, Stadium, dykes and dams, waterwork, Sui Dong, Coastal beach, enclose and cultivate, the work such as environmental protection
Journey.
Based at present to this present situation of geotextiles wilderness demand, the conventional geotextiles structure of tradition is single, tensile strength and
Non-deformability is low, the reduced lifetime of geotextiles.Therefore, those skilled in the art need a kind of new geotextiles of offer badly, so that
Tensile strength and non-deformability are effectively improved, extends the service life and its combination property of geotextiles.
The content of the invention
For defect of the prior art, the present invention is intended to provide a kind of compound maintenance geotextiles of macromolecule and its preparation side
Method.The compound maintenance geotextiles of macromolecule that the present invention is provided are by high-strength composite chopped fiber (ES fibers), Time of Fluff Slurry and high suction
Water-base resin (SAP) composite acupuncture is processed, and it not only possesses the due indices of common geotextiles and performance, and tool
There are excellent water absorbing properties.Specifically, the compound maintenance geotextiles of macromolecule one times of suction more than common geotextiles that the present invention is provided
Water；Wherein, after super absorbent resin water suction 100 times of volumes of expansion and can long-time moisturizing, Time of Fluff Slurry powder can have
Effect absorbs slow release after moisture content, so as to effectively reduce nourishment's cost, the valuable water of using water wisely cost and China
Resource；In addition, composite short fiber has quick permeation, intensity is high, and pulling force is bigger, so the compound maintenance soil of the macromolecule prepared
Work cloth can also be repeatedly used, so can effectively save engineering material cost, in terms of engineering maintenance have significantly it is excellent
Gesture.
Therefore, the present invention provides following technical scheme：

The ES of ES fibers, is that English " answer by Ethylene-Propylene Side By Side " abbreviation, also known as core-skin
Chopped fiber is closed, is a kind of bicomponent fibers of skin-core structure, is the one of the polyolefin series fiber that Japanese Chisso Corporation develops
Kind.The fiber is especially suitable for use as hot blast and penetrates the products, top layer such as technique productions hygienic material, warming inserts, filtering material
The raw materials for production of non-woven fabrics, composite short fiber (ES fibers) is the important materials of non-woven fabrics, and the advantage of non-woven fabrics is liquid
Time of break-through it is shorter, the amount of bleeding back is lower；The fiber is especially suitable for use as hot blast and penetrates technique productions hygienic material, warming filling
The products such as material, filtering material.High hydroscopic resin (SAP) is that a class contains hydrophilic radical and the new function macromolecule of cross-linked structure
Material, with can even thousands of times of hundred times of absorptance itself weight water, can be as a kind of colloid, with certain strong after water suction
Degree and water-retaining property, it is water insoluble, it is also insoluble in organic matter；SAP also has imbibition ability strong, can absorb decades of times to hundreds of times
The liquid of deadweight, its absorption speed is fast, multiplying power is high, safety non-toxic, raw material cheap and easy to get the advantages of.
In the further embodiment of the present invention, fiber is selected from ES fibers, and the water absorption of water-absorbing resins is not less than certainly
100 times of body weight.
