Description

Technical Field

[0001] This utility model relates to the field of rubber belt technology, specifically a weather-resistant and water-stopping rubber belt. Background Technology

[0002] Rubber belts are strips made of rubber or elastic materials. They have high elasticity and extensibility, and achieve fixing, transmission or sealing functions through the reaction force generated by deformation. They are widely used in industrial conveying, document sealing, clothing accessories and other fields.

[0003] Water-stop rubber strips are strip-shaped materials used to fill expansion joints during concrete pouring. Their function is to prevent external water from seeping into the expansion joints, thereby protecting the safety of the building structure. However, existing water-stop rubber strips are prone to aging and uneven expansion and contraction when exposed to high temperature differences and strong ultraviolet radiation for a long time. This leads to a decrease in their adhesion to concrete, forming water seepage channels and endangering the safety of the building structure.

[0004] Based on the above problems, a technical solution for weather-resistant waterproof rubber tape is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a weather-resistant water-stop rubber strip.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a weather-resistant water-stop rubber strip, comprising a strip body, the strip body comprising a water-stop center body, a water-stop wing plate and a plurality of connecting ends, the water-stop wing plate being symmetrically arranged on both sides of the water-stop center body, the plurality of connecting ends being evenly distributed on both sides of the water-stop wing plate, the water-stop wing plate having protrusions evenly distributed between two adjacent connecting ends, and the connecting ends having wavy textures formed on both sides along their length direction.

[0007] The present invention is further configured such that the water-stopping center body is a hollow tubular structure and is filled with water-absorbing resin inside.

[0008] The present invention is further configured such that a reinforcing rib is nested at the end of the connecting end away from the waterstop wing plate, and the reinforcing rib is made of carbon fiber material.

[0009] The present invention is further configured such that the protrusions are semi-circular structures with a height of 0.5-2mm and a spacing of 10-20mm.

[0010] The present invention is further configured such that the depth of the wavy texture is 1-3mm and the wavelength is 5-10mm.

[0011] The present invention is further configured such that the belt body is made of EPDM rubber material.

[0012] In summary, this utility model has the following beneficial effects: the protrusions on the waterstop wing plate and the wavy texture of the connecting end increase the connection between the belt and the building, preventing belt deformation. Moreover, the belt is made of EPDM rubber material, which has good weather resistance and aging resistance. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] A type of weather-resistant waterproof rubber tape, such as Figure 1 As shown, the belt includes a body 1, which includes a water-stopping center body 2, water-stopping flanges 3, and several connecting ends 4. The water-stopping flanges 3 are symmetrically arranged on both sides of the water-stopping center body 2, and the several connecting ends 4 are evenly distributed on both sides of the water-stopping flanges 3. The water-stopping flanges 3 have protrusions 31 evenly distributed between two adjacent connecting ends 4. The protrusions 31 are semi-circular structures with a height of 0.5-2mm and a spacing of 10-20mm. When the protrusions 31 are compressed, they will undergo elastic deformation, forming a multi-point seal with the contact surface, which improves the reliability of the seal. At the same time, the structure of the protrusions 31 can increase the interlocking effect between the belt body 1 and the concrete, preventing sliding displacement.

[0017] The connecting end 4 has wavy patterns 41 on both sides along its length. The depth of the wavy patterns 41 is 1-3mm and the wavelength is 5-10mm. The wavy patterns 41 can increase the friction between the rubber belt and the concrete, prevent slippage during installation, and absorb some of the deformation energy when the belt body 1 is deformed under pressure, reducing the pressure concentration of the belt body 1.

[0018] like Figure 1As shown, specifically, the water-stopping center body 2 is a hollow tubular structure filled with water-absorbing resin. The water-absorbing resin can absorb excess moisture and prevent the belt body 1 from expanding and deforming. When dry, the water-absorbing resin releases moisture, which helps maintain the elasticity of the belt body 1. The end of the connecting end 4 away from the water-stopping wing plate 3 is nested with a reinforcing rib 5. The reinforcing rib 5 is made of carbon fiber material, which can improve the tensile strength and tear resistance of the connecting end 4.

[0019] In this embodiment, the belt 1 is made of ethylene propylene diene monomer (EPDM) rubber material. EPDM rubber material is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. Its main chain is composed of chemically stable saturated hydrocarbons, and its side chains contain unsaturated double bonds, which gives it weather resistance and aging resistance.

[0020] Manufacturing process: Mix EPDM rubber, plasticizer and other raw materials in proportion, mix evenly in a mixer, then extrude through an extruder to form a preform, then vulcanize the preform to crosslink and solidify the rubber molecular chains, finally embed reinforcing ribs 5 into the connecting end 4, and combine the reinforcing ribs 5 with the belt body 1 through a hot pressing process.

[0021] Practical effect: The protrusions 31 on the waterstop wing plate 3 form a multi-point seal with the contact surface, and increase the interlocking effect between the belt body 1 and the concrete. The wavy texture 41 of the connecting end 4 increases the friction between the rubber belt and the concrete and absorbs some deformation energy, thereby increasing the connection stability between the belt body 1 and the building and preventing the belt body 1 from deforming due to external forces.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
