Abstract
The invention relates to a novel composite waterproof carpet. The novel composite waterproof carpet comprises a waterproof carpet main body, wherein the waterproof carpet main body is divided into two layers; the upper layer is a non-woven cloth layer; the lower layer is a non-woven geotechnical cloth layer; a plurality of concave pits are formed on the surface of the non-woven geotechnical cloth layer and internally provided with water absorption dilatants; and the non-woven cloth layer is connected with the non-woven geotechnical cloth layer in a sewing manner. The novel composite waterproof carpet is simple in structure and low in production cost; non-woven cloth is arranged at the upper layer, so that the carpet is bright in color and attractive in appearance; non-woven geotechnical cloth is arranged at the lower layer, so that the carpet is good in abrasive resistance and long in service life, can be widely applied to industries of municipal engineering, water conservancy, gardens, families and the like, and is wide in application scope; when the carpet meets water, sodium bentonite particles absorb water and expand to form a compact gel structure, and water molecules cannot penetrate, so that the carpet has seepage control and water resistance effects, and the permeability coefficient of the carpet can reach as high as 10-9cm/s.
Description
Technical field
The present invention relates to a kind of NEW TYPE OF COMPOSITE waterproof blanket, relate in particular to a kind of NEW TYPE OF COMPOSITE waterproof blanket.
Background technology
Existing waterproof blanket is two-layer mostly; The upper strata is that plastic flat fiber braided geotextile layer, lower floor are the non-woven geotextile layer; Waterproof blanket application life of this kind structure is short, the antiseepage block-water effect is poor, can not satisfy instructions for use after long-time the use, seeps water easily, leakage accident.
Summary of the invention
The present invention provides a kind of simple in structure, good water-proof effect, NEW TYPE OF COMPOSITE waterproof blanket easy to use in order to overcome the above problems.
Technical scheme of the present invention is: comprise the waterproof blanket main body; Described waterproof blanket body portion is two-layer; The upper strata is a nonwoven layer, and lower floor is the non-woven geotextile layer, and described non-woven geotextile laminar surface is provided with some pits; Be provided with the imbibition thing in the described pit, said nonwoven layer is connected with non-woven geotextile layered suture system.
Described imbibition thing is the sodium bentonite particle.
The present invention is simple in structure, cost of production is low, and the upper strata is a nonwoven, and is bright-colored, handsome in appearance; Lower floor is that the non-woven geotextile scuff resistance is good, long service life, can be widely used in industries such as municipal administration, water conservancy, gardens, family expenses, and is applied widely; After the present invention met water, the imbibition of sodium bentonite particle formed fine and close gel structure; Hydrone can't see through, thereby plays the antiseepage resistance effect, and its transmission coefficient can reach 10
-9Cm/s.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1 is nonwoven layer among the figure, the 2nd, and non-woven geotextiles layer, the 3rd, sodium bentonite particle.
The specific embodiment
A kind of NEW TYPE OF COMPOSITE waterproof blanket comprises the waterproof blanket main body, and described waterproof blanket body portion is two-layer; The upper strata is a nonwoven layer 1; Lower floor is a non-woven geotextile layer 2, and described non-woven geotextile layer 2 surface are provided with some pits, are provided with the imbibition thing in the described pit; Said nonwoven layer 1 is made with non-woven geotextile layer 2 and is connected, and described imbibition thing is a sodium bentonite particle 3.
Claims (2)
1. NEW TYPE OF COMPOSITE waterproof blanket; Comprise the waterproof blanket main body, it is characterized in that: described waterproof blanket body portion is two-layer, and the upper strata is a nonwoven layer; Lower floor is the non-woven geotextile layer; Described non-woven geotextile laminar surface is provided with some pits, is provided with the imbibition thing in the described pit, and said nonwoven layer is connected with non-woven geotextile layered suture system.
