Description

Technical Field

[0001] This utility model relates to the field of automotive sealing strip technology, specifically a high-sealing automotive sealing strip. Background Technology

[0002] Automotive sealing strips are strips of rubber or plastic material installed on various parts of a car (such as doors, windows, hood, etc.). Sealing strips can effectively block the entry of moisture and wind, maintaining a comfortable environment inside the car. The material of sealing strips is generally rubber or synthetic material with good weather resistance.

[0003] In the existing technology, the door sealing strip is prone to wear and tear as the door is opened and closed. With long-term repeated use, the sealing strip on the door is worn down, which can easily lead to poor sealing performance.

[0004] To overcome the above shortcomings, a prior art Chinese patent (application number 201920278047.2) discloses an automotive sealing strip. The sealing strip body has at least an mounting part constituting the sealing strip body for installation on a car, and a sponge colloid exposed due to its installation on the car. A dense adhesive decorative layer is specifically covered on the exposed surface of the sponge colloid. The automotive sealing strip, by covering the exposed surface of the sponge colloid with a sealant decorative layer, has a better appearance quality because the sealant decorative layer has better surface smoothness and fineness. At the same time, the sealant decorative layer also has better wear resistance, thereby improving the wear resistance of the automotive sealing strip, effectively preventing problems such as surface wear, flaking, and contamination of sheet metal, and enabling the automotive sealing strip to have a better performance.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation. For example, the sealing performance of automotive sealing strips is easily worn down to varying degrees with the use of the product, and the sealing performance is prone to defects, which can easily lead to a decrease in waterproofing effect. Utility Model Content

[0006] The purpose of this utility model is to provide a high-sealing automotive sealing strip to solve the problem mentioned in the background art that the sealing performance of automotive sealing strips is easily damaged to varying degrees with the use of the product, and the sealing performance is prone to failure and defects, which can easily lead to a decrease in waterproof effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing automotive sealing strip, comprising a sealing strip body and a groove provided inside the sealing strip body, and a glass contact surface provided on the right side of the sealing strip body; a TPV sliding material is provided on the surface of the glass contact surface, and a first reverse tooth block is provided inside the groove of the sealing strip body.

[0008] Furthermore, a sealing protrusion is provided on the left side of the sealing strip body, and there are two sealing protrusions.

[0009] Furthermore, a second reverse tooth block is provided inside the groove of the sealing strip body, and the second reverse tooth block corresponds to the first reverse tooth block.

[0010] Furthermore, the groove of the sealing strip body is provided with 710 type hot melt butyl rubber and 656 type hot melt butyl rubber, and two openings are opened on the left side of the sealing strip body.

[0011] Furthermore, the sealing strip body has a groove inside, and a steel strip is installed inside the groove, and both the steel strip and the groove are U-shaped.

[0012] Furthermore, a substrate treatment coating is adhered to the surface of the sealing strip body, a buffer coating is adhered to the surface of the substrate treatment coating, and a protective layer is adhered to the surface of the buffer coating.

[0013] Furthermore, the substrate treatment coating is made of epoxy resin primer, the buffer coating is made of silicone-modified polyurethane, and the protective layer is made of fluorocarbon coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Two sealing protrusions are provided on the left side of the sealing strip body, which can be correspondingly engaged with the door frame position when the sealing strip body is installed, thereby improving the installation effect. At the same time, when the sealing strip body is used, it is embedded into the car door frame position through the slot, and the TPV sliding material on the glass contact surface improves the wear resistance.

[0016] Furthermore, the design of the first and second reverse tooth blocks inside the slot can further improve the stability of the installation, prevent the sealing strip body from easily falling off after installation, and further ensure the stability of the installation.

[0017] Furthermore, two types of hot-melt butyl rubber, namely type 710 hot-melt butyl rubber and type 656 hot-melt butyl rubber, are set inside the card slot, which have better sealing performance. Even if the car is submerged in water, the parts using this sealing strip will not leak. In addition, a groove is opened inside the sealing strip body to place a steel strip, which can improve the strength and stability of the sealing strip and make the sealing strip body more durable.

[0018] 2. During the production of the sealing strip body, a substrate treatment coating can be attached to the surface of the sealing strip body by electrostatic spraying or impregnation process. The substrate treatment coating is made of epoxy resin primer and its surface is pretreated to facilitate subsequent processing.

[0019] Furthermore, after the initial treatment, an electrostatic spraying or impregnation process is applied to the surface to allow the buffer coating to adhere. The buffer coating is made of silicone-modified polyurethane, which can achieve media isolation, ensure flexibility, and prevent corrosive materials such as oil and salt spray from entering the sealing strip, thereby improving its service life. Finally, an electrostatic spraying or impregnation process is applied to the surface to allow the protective layer to adhere. The protective layer is made of fluorocarbon coating to improve overall wear resistance and reduce dirt adhesion to the surface of the sealing strip. Attached Figure Description
