Abstract
The utility model discloses a cross membrane polymer waterproof coiled material, which belongs to the field of waterproof coiled materials and comprises a rubber flame-retardant layer, a strong cross membrane layer, a self-adhesive layer and a sand layer.
Description
Technical Field
The utility model relates to the field of waterproof rolls, in particular to a crossed membrane polymer waterproof roll.
Background
The crossed membrane high polymer waterproof coiled material is a waterproof material product manufactured by dipping a high polymer waterproof material on a matrix, is mainly applied to building walls, roofs, tunnels, highways, refuse landfills and the like, plays a role in resisting external rainwater and underground water leakage, is used as a leakage-free connection between an engineering foundation and a building, is a first barrier for waterproofing of the whole engineering, and plays a vital role in the whole engineering.
At present, the crossed membrane polymer waterproof roll can be used as a common building material in foundation construction engineering, can form a firm waterproof structure with a post-cast concrete structure in advance, and provides a new challenge for the firmness of the crossed membrane polymer waterproof roll along with the continuous improvement of engineering implementation standards.
SUMMERY OF THE UTILITY MODEL
In order to improve the firmness of the conventional crossed membrane polymer waterproof roll, the utility model provides a crossed membrane polymer waterproof roll.
A cross membrane macromolecule waterproof coiled material comprises a rubber flame-retardant layer, a strong cross membrane layer, a self-adhesive layer and a sand layer; the rubber flame-retardant layer, the strong cross film layer and the self-adhesive layer sequentially form a layered structure from top to bottom; the lower surface of the self-adhesive layer is provided with a strip-shaped groove, and the sand layer is arranged in the strip-shaped groove.
Preferably, the sand layer is quartz sand with the granularity slightly larger than the depth of the strip-shaped groove.
Preferably, the granularity of the quartz sand is 1.1-1.3 mm; preferably, the thickness of the self-adhesive layer is 2 mm; the depth of the strip-shaped groove is 1 mm.
Preferably, the thickness of the rubber flame-retardant layer is 1mm-2 mm.
Preferably, the thickness of the strong crossed film layer is 4 mm.
Preferably, the waterproof roll further comprises: the isolating film can be removed; the removable release film is adhered to the lower surface of the self-adhesive layer.
Compared with the prior art, the utility model has the beneficial effects that:
the technical scheme provided by the utility model comprises the following steps: the waterproof roll comprises a rubber flame-retardant layer, a strong cross film layer, a self-adhesive layer and a sand layer, wherein the sand layer is arranged in a strip-shaped groove of the self-adhesive layer, so that the sand layer can be bonded with base layer concrete under the condition that the self weight of the waterproof roll is not increased, the concrete is solidified to form an integrated structure, and the construction firmness of the cross film high-polymer waterproof roll is improved.

FIG. 2 is a schematic view of the lower surface of the self-adhesive layer of the present invention;
wherein, 1-a rubber flame-retardant layer; 2-strong crossed film layer; 3-a self-adhesive layer; 4-a sand layer; 5-the release film can be removed.
Detailed Description
For a better understanding of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings and examples.
The embodiment provides a crossed membrane macromolecule waterproof coiled material, wherein the vertical cross-sectional schematic diagram of the waterproof coiled material is shown in fig. 1, and the waterproof coiled material comprises a rubber flame-retardant layer 1, a strong crossed membrane layer 2, a self-adhesive layer 3 and a sand layer 4; the rubber flame-retardant layer 1, the strong cross film layer 2 and the self-adhesive layer 3 sequentially form a layered structure from top to bottom; from the lower surface of viscose layer 3 is provided with the bar recess, and set up in the bar recess sand bed 4, sand bed 4 is used for the increase from the adhesive force of viscose layer 3 with outside concrete, from the lower surface schematic diagram of viscose layer 3 as shown in fig. 2.
The sand layer 4 is made of quartz sand with the granularity slightly larger than the depth of the strip-shaped groove, and when the quartz sand is arranged in the strip-shaped groove, the quartz sand can protrude out of the lower surface of the self-adhesive layer 3 and is bonded with a concrete material in depth, so that a firmer integrated structure is formed.
The granularity of the quartz sand is 1.1-1.3 mm; the thickness of the self-adhesive layer 3 is 2 mm; the depth of the strip-shaped groove is 1 mm.
The thickness of the rubber flame-retardant layer 1 is 1mm-2 mm.
The thickness of the strong crossed film layer 2 is 4 mm. The waterproof roll further comprises: the isolating film 5 can be removed; the removable isolating film 5 is adhered to the lower surface of the self-adhesive layer 3, in this embodiment, when the removable isolating film 5 is sealed on the self-adhesive layer 3, the removable isolating film is adhered to the area between the strip-shaped grooves, so that the removable isolating film is prevented from being adhered to the sand layer 4, and the sand layer 4 is damaged when the removable isolating film is removed.
It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
