Abstract
The invention discloses a composite waterproof blanket and a making method, and belongs to the technical field of earthworks. According to the waterproof blanket, sodium-based bentonite is arranged between two layers of geotextile, fibers are placed between the two layers of geotextile, and a layer of light curing adhesive is arranged outside the geotextile of the lower layer to form the four-layer waterproof blanket. Adhesive coating and light curing processes are increased in the making method. The method comprises the following steps of: 1, coating the sodium-based bentonite, wherein a non-woven fabric and a woven fabric are adopted on the upper and lower layers of geotextile respectively, and the sodium-based bentonite is added between the two layers of geotextile; 2, needling compounding: selecting a needling machine, making a felting needle pass through the geotextile of the upper layer, the sodium-based bentonite and the geotextile of the lower layer, inversely hooking the felting needle to scrape the fibers of the geotextile of the upper layer, and reserving the fibers between the two layers of geotextile after the needle is returned so as to finish needling compounding; 3, coating adhesive: coating a layer of light curing adhesive on the geotextile of the lower layer of naked fiber thread ends; and 4, performing light curing: quickly curing the light curing adhesive under the irradiation of ultraviolet light in a shaded environment to form a layer of light curing adhesive film so as to form the four-layer waterproof blanket.
Description
Technical field
The invention belongs to the geotechnics field, be specifically related to a kind of waterproof blanket.
Background technology
The sodium bentonite waterproof blanket is popularized in the application of earthwork engineering gradually as this a kind of nonvolatil environment-friendly impervious material.Sodium bentonite imbibition under the restriction of two-layer geotextiles forms fine and close gelatinous layer.Because the brute force of adhering between the two-layer nonwoven there are differences, so the restricted bad control to expanding, usually therefore and on the low side, in order to remedy this defective, giving birth to manufacturer often needs to pay a high price.
Summary of the invention
The purpose of this invention is to provide a kind of composite water-proof blanket and preparation method, with problems such as solution prior art fissility differences.
The present invention mainly is made up of geotextiles, sodium bentonite, solving the technical scheme that its problem adopts is between two-layer geotextiles sodium bentonite to be set, fiber places between the two-layer geotextiles, at lower floor's geotextiles outside coating one deck optic-solidified adhesive, constitutes four layers of waterproof blanket.Its preparation method increases gluing and photocuring operation, and concrete processing step is as follows:
1, apply sodium bentonite: geotextiles adopts nonwoven and woven cloth respectively up and down, adds sodium bentonite between two-layer geotextiles;
2, acupuncture is compound: adopt needing machine, pricker is passed upper strata geotextiles, sodium bentonite and lower floor's geotextiles, the pricker barb scrapes upper strata geotechnique's measuring fiber, and fiber is kept somewhere between two geotextiles after the back stitching, and it is compound to finish acupuncture;
3, gluing: on lower floor's geotextiles of uncovered fibres the end of a thread, smear one deck optic-solidified adhesive;
4, photocuring: optic-solidified adhesive under the lucifuge environment, accept the 360mm UV-irradiation after, solidify rapidly, form one deck light-curable glue film, constitute four layers of waterproof blanket.
Adopt good effect of the present invention to be:
1, the stripping performance excellence of waterproof blanket product, fluctuation reduces relatively, and far above normal line;
2, the curing rate of optic-solidified adhesive is fast, can not produce the production capacity restriction to the equipment of high-speed cruising.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is structural representation of the present invention;
1 geotextiles, 2 sodium bentonites, 3 optic-solidified adhesives, 4 fibers among the figure.
The specific embodiment
As shown in the figure: between two-layer geotextiles 1, add sodium bentonite 2, fiber 4 places between the two-layer geotextiles, and upper and lower geotextiles 1 adopts nonwoven or woven cloth respectively, smears optic-solidified adhesive 3 at lower floor's geotextiles 1 outer surface, optic-solidified adhesive 3 solidifies, and constitutes four layers of waterproof blanket.Its preparation method is as follows:
1, apply sodium bentonite: geotextiles adopts nonwoven and woven cloth respectively up and down, adds sodium bentonite between two-layer geotextiles;
2, acupuncture is compound: adopt needing machine, pricker is passed upper strata geotextiles, sodium bentonite and lower floor's geotextiles, the pricker barb scrapes upper strata geotechnique's measuring fiber, and fiber is kept somewhere between two geotextiles after the back stitching, and it is compound to finish acupuncture;
3, gluing: smear one deck optic-solidified adhesive on lower floor's geotextiles of uncovered fibres the end of a thread, the optic-solidified adhesive of smearing is a light-sensitive emulsion;
4, photocuring: light-sensitive emulsion under the lucifuge environment, accept the 360mm UV-irradiation after, solidify rapidly, form one deck light-curable glue film, constitute four layers of waterproof blanket.
Claims (2)
1. composite water-proof blanket and preparation method, mainly be made up of geotextiles, sodium bentonite, it is characterized in that between two-layer geotextiles sodium bentonite being set, fiber places between the two-layer geotextiles, lower floor's geotextiles arranged outside one deck optic-solidified adhesive constitutes four layers of waterproof blanket therein.
2. composite water-proof blanket and preparation method is characterized in that preparation method sets up gluing and photocuring operation, and concrete processing step is as follows:
