Abstract
The utility model relates to a kind of sodium-based bentonite waterproof carpet.It comprises short fiber base cloth layer and base fabric, between short fiber base cloth layer and base fabric, be fixed with Na-bentonite soil layer by acupuncture mode, is coated with moisture-curable glue-line at base fabric lateral surface.The utility model structure is simple, and reasonable in design, peel strength is high, and cost is low.
Description
Technical field:
The utility model relates to a kind of sodium-based bentonite waterproof carpet.
Background technology:
Sodium-based bentonite waterproof carpet is a kind of environmental protection, efficiently impervious material, popularizes gradually in the application in earthwork engineering field.During use, sodium bentonite imbibition under the restriction of two-layer geotextiles, forms fine and close gelatinous layer.Because geotextiles and bentonitic adhesive force there are differences, reduce geotextiles to bentonitic restriction.Peel strength between two-layer geotextiles is an important indicator of GCL.In the preparation process of waterproof blanket, by barb acupuncture, the fiber wherein in one deck geotextiles, through between two-layer geotextiles, forms certain peel strength between.Perforating fiber is exposed to the outside of another layer of geotextiles, and easily detach when an external force is applied, peel resistance is poor.Meanwhile, higher engineering applications is required for some peel strengths, high-strength short fiber base cloth must be used just to reach requirement, virtually add production cost.
Utility model content:
The utility model provides a kind of sodium-based bentonite waterproof carpet, and its structure is simple, and reasonable in design, peel strength is high, and cost is low, solves problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is: it comprises short fiber base cloth layer and base fabric, between short fiber base cloth layer and base fabric, be fixed with Na-bentonite soil layer by acupuncture mode, be coated with moisture-curable glue-line at base fabric lateral surface.
Described short fiber base cloth layer is acupuncture polypropylene chopped fiber base cloth or terylene short fiber base cloth.
Described base fabric is polypropylene fibre woven cloth.
Described Na-bentonite soil layer is natural sodium bentonite or Prof. Du Yucang sodium bentonite.
Described moisture-curable glue-line is polyurethane moisture-curable glue.
The utility model adopts such scheme, structure is simple, reasonable in design, cost is low, moisture-curable glue-line utilizes in air or the moisture-curing of base fabric lateral surface, glued membrane after solidification by be perforated through base fabric, from the fiber set on short fiber base cloth layer, make fiber not easily detach out outside base fabric under external force, thus improve the peel strength between short fiber base cloth layer and base fabric.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure, 1, short fiber base cloth layer, 2, Na-bentonite soil layer, 3, base fabric, 4, moisture-curable glue-line, 5, fiber.
Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in FIG., the utility model comprises short fiber base cloth layer 1 and base fabric 3, between short fiber base cloth layer 1 and base fabric 3, be fixed with Na-bentonite soil layer 2 by acupuncture mode, is coated with moisture-curable glue-line 4 at base fabric 3 lateral surface.Short fiber base cloth layer 1 is acupuncture polypropylene chopped fiber base cloth or terylene short fiber base cloth.Base fabric 3 is polypropylene fibre woven cloth.Na-bentonite soil layer 2 is natural sodium bentonite or Prof. Du Yucang sodium bentonite.Moisture-curable glue-line 4 is polyurethane moisture-curable glue.The reaction of moisture of active group easily and in air of polyurethane moisture-curable glue, film-forming, not only has outside good adhesive strength, impact strength, also has ageing-resistant, low temperature resistant, endurance, water-fast, resistance to wet goods characteristic.
Preparation method of the present utility model is as follows:
One, using base fabric 3 as bottom carrier, sodium bentonite is sprinkling upon on base fabric 3 uniformly, then short fiber base cloth layer 1 is covered on sodium bentonite;
Two, with needing machine, pricker is penetrated short fiber base cloth layer 1, sodium bentonite 2 and base fabric 3, the barb of pricker is made to scrape fiber 5 on short fiber base cloth layer 1, fiber 5 is made to be retained between short fiber base cloth layer 1, sodium bentonite and base fabric 3 after back stitching, complete acupuncture compound, sodium bentonite is fixed between short fiber base cloth layer 1 and base fabric 3, forms Na-bentonite soil layer 2;
Three, one deck moisture-curable glue is applied at the lateral surface of the base fabric 3 having fiber to penetrate;
Four, utilize in air or the moisture of base fabric 3 lateral surface, moisture-curable glue rapid curing, form one deck solidified glue film, by fiber set exposed for woven cloth lateral surface.
The utility model is after completing base fabric 3, acupuncture compound between Na-bentonite soil layer 2 and short fiber base cloth layer 1, one deck moisture-curable glue is applied again at base fabric 3 lateral surface, in the active group of moisture-curable glue and air or the reaction of moisture of base fabric 3 lateral surface, film-forming, glued membrane after solidification by be perforated through base fabric 3, from fiber 5 set on short fiber base cloth layer 1, there is good adhesive strength and impact strength, masterpiece used time not easily detaches out outside to make it, thus improves the peel strength of short fiber base cloth layer 1 and base fabric 3.
The utility model is when meeting water, inflatable more than 24 times of Na-bentonite soil layer 2, it is made to form the high and colloid system that filter loss is low of uniform stickiness, under the restriction of short fiber base cloth layer 1 and base fabric 3, Na-bentonite soil layer 2 is made to become orderly expansion from unordered, the imbibition result continued allows Na-bentonite soil layer 2 self reach closely knit, thus have waterproof action.
Above-mentioned detailed description of the invention can not as the restriction to the utility model protection domain, and for those skilled in the art, any alternate modification make the utility model embodiment or conversion all drop in protection domain of the present utility model.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
