Abstract
A non-asphalt-based waterproof coiled material belongs to the field of waterproof coiled materials and comprises an anti-aging layer, a waterproof layer and an outward-convex self-adhesive layer, wherein the outward-convex self-adhesive layer is provided with a mound-shaped bulge, so that the contact area with poured concrete can be increased when the outward-convex self-adhesive layer is constructed and paved in advance, the adhesion area is further increased, and the adhesion firmness of the waterproof coiled material is improved; in addition, the concrete can enter into the miniature circular groove arranged on the hill-shaped bulge to form firm physical mortise and tenon joints.
Description
Technical Field
The utility model relates to the field of waterproof coiled materials, in particular to a non-asphalt-based waterproof coiled material.
Background
The non-asphalt base self-adhesive waterproof roll is one waterproof roll developed for underground tunnel engineering, and may be used in forming firm waterproof roll with concrete structure.
In the projects such as underground tunnels and the like, the ground, the side walls and the top surfaces of the project sites need to be constructed in an all-around manner, and in order to meet the project waterproof requirements, the viscosity of the non-asphalt-based waterproof coiled material needs to be continuously enhanced and improved.
SUMMERY OF THE UTILITY MODEL
In order to further enhance the viscosity requirement of the non-asphalt-based waterproof roll, the utility model provides a non-asphalt-based waterproof roll.
A non-asphalt-based waterproofing membrane, the waterproofing membrane comprising: the anti-aging layer, the waterproof layer and the convex self-adhesive layer; the anti-aging layer, the waterproof layer and the outward convex self-adhesive layer sequentially form a layered structure from top to bottom; the lower surface of the outward convex self-adhesive layer is provided with a mound-shaped bulge, and a miniature circular groove is formed in the mound-shaped bulge.
Preferably, the anti-aging layer is a high-density polyethylene resin, and an anti-aging agent, an antioxidant, an ultraviolet absorber and a stabilizer are added.
Preferably, the waterproof layer is a vinyl acetate resin layer.
Preferably, the waterproof roll further comprises: an isolation layer;
the isolation layer is attached to the lower surface of the convex 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 an anti-aging layer, a waterproof layer and an outward-convex self-adhesive layer, wherein the outward-convex self-adhesive layer is provided with a mound-shaped bulge, so that the contact area with poured concrete can be increased during construction pre-paving, the adhesion area is further increased, and the adhesion firmness of the waterproof roll is improved; in addition, the concrete can enter into the miniature circular groove arranged on the hill-shaped bulge to form firm physical mortise and tenon joints.

FIG. 1 is a schematic vertical sectional view of a waterproof roll of the present invention;
FIG. 2 is a partial schematic view of a mound-like protrusion according to the present invention;
FIG. 3 is a bottom view of the self-adhesive layer of the present invention;
wherein, 1-an anti-aging layer; 2-waterproof layer; 3-an outward convex self-adhesive layer; 4-a mound-like protrusion; 5-a miniature circular groove; 6-isolating layer.
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 present embodiment provides
A non-asphalt base waterproof coiled material, wherein the vertical section schematic diagram of the waterproof coiled material is shown in figure 1, and the waterproof coiled material comprises: an anti-aging layer 1, a waterproof layer 2 and an outward convex self-adhesive layer 3; the anti-aging layer 1, the waterproof layer 2 and the convex self-adhesive layer 3 sequentially form a layered structure from top to bottom; the lower surface of the outward convex self-adhesive layer 3 is provided with a hill-shaped protrusion 4, the hill-shaped protrusion 4 is provided with a micro circular groove 5, and a partial schematic view of the hill-shaped protrusion 4 is shown in fig. 2 (in order to represent the structure of the micro circular groove 5, the vertical cross-sectional schematic view of the hill-shaped protrusion 4 is adopted in the figure). The mound-shaped bulge 4 is integrally arranged on the convex self-adhesive layer 3 and is integrally manufactured, and the ground schematic diagram of the convex self-adhesive layer 3 is shown in fig. 3.
The miniature circular groove 5 is a funnel-shaped groove with the diameter of the groove hole larger than the inner diameter, and when the miniature circular groove is contacted with a concrete substrate, concrete can be poured into the groove and solidified to form strong chemical crosslinking and physical mortise and tenon joint.
The anti-aging layer 1 is made of high-density polyethylene resin, and is added with an anti-aging agent, an antioxidant, an ultraviolet absorber and a stabilizer. The anti-aging layer 1 is used as a surface layer, and an anti-aging agent, an antioxidant, an ultraviolet absorber and a stabilizer are added to achieve the effect of stability and durability, so that the use reliability of the waterproof roll material is improved.
The waterproof roll further comprises: an isolation layer 6; the isolating layer 6 is attached to the lower surface of the convex self-adhesive layer 3; the isolation layer 6 is a removable isolation film with a protective effect.
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.
