Embodiment 1

[0023] The roof strip of this embodiment includes a composite rubber layer, the two ends of the composite rubber layer are bent to form a bending part for clamping with the roof of the vehicle, and the bending part is connected with spokes for decoration and sealing. The rubber layer is composed of a silicone rubber layer, an EPDM rubber layer and a nitrile rubber layer. The two sides of the silicone rubber layer are covered with an EPDM rubber layer, and the two outer sides of the EPDM The nitrile rubber layer is sandwiched with a stainless steel wire mesh layer.

Embodiment 2

[0025] The roof strip of this embodiment includes a composite rubber layer, the two ends of the composite rubber layer are bent to form a bending part for clamping with the roof of the vehicle, and the bending part is connected with spokes for decoration and sealing. The rubber layer is composed of a silicone rubber layer, an EPDM rubber layer and a nitrile rubber layer. The two sides of the silicone rubber layer are covered with an EPDM rubber layer, and the two outer sides of the EPDM The nitrile rubber layer is sandwiched with a stainless steel wire mesh layer.

Abstract

The invention discloses a top strap for a vehicle. The top strap comprises a composite rubber layer, and the two ends of the composite rubber layer are bent to form two bending portions which are used for being clamped on the top of the vehicle. Each bending portion is connected with a spoke for decorating and sealing. The composite rubber layer is formed by compositing a silicone rubber layer, ethylene propylene diene monomer rubber layers and Buna-N rubber layers. The two sides of the silicone rubber layer are covered with the ethylene propylene diene monomer rubber layers respectively. The two outer sides of the ethylene propylene diene monomer rubber layers are covered with the Buna-N rubber layers respectively. A stainless steel wire mesh layer is arranged in the silicone rubber layer in a clamped mode. The top strap for the vehicle has the advantages that the layers are not prone to falling off, and the service life of the top strap is prolonged.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a roof strip. Background technique [0002] The roof strip is used for the decoration and sealing of the top of the vehicle. The performance of the roof strip not only affects the sealing performance of the vehicle, but also greatly affects the vehicle decoration. [0003] The making of existing roof strip mostly adopts rubber layer to make, in order to strengthen the rigidity of roof strip, the inside of rubber layer is provided with stainless steel or aluminum alloy plate as support frame, promptly lays rubber layer on both sides of support frame. [0004] However, after a period of time, the support frame and the rubber layer often fall off and separate, resulting in a short service life of the roof strip and affecting the decorative appearance of the vehicle. Contents of the invention [0005] In order to solve the problem that the supporting frame and rubber layer o...
