Problems solved by technology

There is also a method of compounding a layer of ultra-high molecular polyethylene layer by one-piece extrusion on the skeleton part of the EPDM rubber matrix, and at the same time compounding fluff or silicon-based coating interface on the lip surface of the deformed part of the matrix by flocking or spraying process , although the friction coefficient of the skeleton part is reduced, the friction coefficient of the deformation part is still relatively large, and there are also deficiencies
There is also a thermoplastic elastomer (TPV) material formed by changing the glass run strip of EPDM rubber into EPDM rubber and polypropylene (PP) to improve the friction performance of EPDM rubber to improve the structure, but thermoplasticity Elastomer materials cannot reach the level of EPDM materials in terms of cost, compression set and heat aging, which leads to the performance of the guide groove rubber strips not meeting the requirements

Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] Please refer to Figure 1 to Figure 9 According to an embodiment of the present invention, a car door glass run channel rubber strip includes a guide channel base 10 and an interface layer 20 , and the guide channel base 10 includes a base skeleton part 11 and a base deformation part 12 . The base skeleton part 11 is fixed on the automobile door frame (not shown), the end of the base deformation part 12 is connected with the base skeleton part 11, and the head end is attached to the automobile glass 40 . The material of the base skeleton part 11 and the base deformation part 12 is EPDM rubber with the same hardness, and the interface layer 20 is an ultrahigh molecu...

Abstract

The invention discloses a car door glass guide groove adhesive tape. The car door glass guide groove adhesive tape comprises a guide groove substrate and an interface layer. The guide groove base bodycomprises a base body framework part and a base body deformation part. The base body framework part is fixed on a door frame of a car door; the tail end of the base body deformation part is connectedwith the base body framework part, the head end of the base body deformation part is attached to car glass, the base body framework part and the base body deformation part are made of ethylene propylene diene monomer rubber with the same hardness, and the interface layer covers the surface of the guide groove base body and is used for reducing friction resistance generated when the guide groove base body makes contact with the car glass. The invention further discloses a preparation method of the car door glass guide groove adhesive tape, and the preparation method is applied to the car doorglass guide groove adhesive tape. According to the glass guide groove adhesive tape and the preparation method thereof disclosed by the invention, the interface layer covers the surface of the ethylene propylene diene monomer guide groove base body, so that the friction resistance between the glass guide groove adhesive tape and vehicle door glass is reduced while the supporting strength of the glass guide groove adhesive tape is ensured, and the use power consumption of a lifter motor is reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a glass run groove rubber strip for a car door and a preparation method thereof. Background technique [0002] Ordinary car door glass run groove strip is an important waterproof sealing part in the door, which plays the role of isolation and diversion of rainwater outside the door from flowing into the interior of the car from the gap between the glass and other door structures, and also guides the glass when the door glass is raised and lowered. The role of lubrication buffer. [0003] Existing and existing door glass run strips are made of a variety of materials, such as pure ethylene propylene diene monomer (EPDM) materials. But there are still deficiencies, it can only play the role of rainwater isolation and glass guiding and buffering, but because the EPDM material itself has a large friction coefficient during the glass lifting process, the glass lifting resistance wi...
