Embodiment 1

[0025] The manufacturing process of the automobile door frame sealing strip provided in this embodiment is to reprocess the already processed and formed sealing strip body to finally manufacture the automobile door frame sealing strip, including the following steps:

[0026] ① Vulcanize the outer surface 6 of the molded sealing strip body with the clamping part 1 exposed inside the car: the material of the clamping part is EPDM (EPDM, Ethylene-Propylene-DieneMonomer) , put the clamping part 1 into a hot air vulcanization box, and vulcanize the outer surface 6 at a temperature of 240°C;

[0027] ② Adhesive coating of the exterior decoration layer 4 on the outer surface 6 of the vulcanized clamping part 1: the exterior decoration layer 4 is in the form of a sheet, and the material of the exterior decoration layer 4 is a thermoplastic elastomer (i.e. TPE, thermoplastic lastomer), in this embodiment, the thermoplastic elastomer is specifically thermoplastic vulcanizate (i.e. TPV, ...

Embodiment 2

[0030] The manufacturing process of the automobile door frame sealing strip provided in this embodiment comprises the following steps:

[0031] a. Processing the exterior decoration layer 4 of the automobile door frame weather strip: extruding the exterior decoration layer 4 with a thermoplastic vulcanizate extruder (i.e. a common TPV extruder);

[0032] b. Vulcanize the outer surface 6 of the formed sealing strip body with the clamping part 1 exposed in the car: the material of the clamping part is EPDM (EPDM, Ethylene-Propylene-DieneMonomer) ), putting the clamping part 1 into a hot air vulcanization box, and vulcanizing the outer surface 6 at a temperature of 260°C;

[0033] c. Adhesively coat the outer decoration layer 4 on the outer surface 6 of the clamping part 1 after vulcanization: the outer decoration layer 4 is in the shape of a sheet, and the material of the outer decoration layer 4 is thermoplastic elastic body (that is, TPE, thermoplasticlastomer), in this embod...

Embodiment 3

[0036] The manufacturing process of the automobile door frame sealing strip provided in this embodiment comprises the following steps:

[0037] 1. process the described exterior layer 4 of the automobile door frame weather strip: utilize a thermoplastic vulcanizate extruder (i.e. a common TPV extruder) to extrude the exterior layer 4;

[0038] II. Vulcanize the outer surface 6 of the clamping part 1 of the formed weather strip body exposed in the car: the material of the clamping part is EPDM (EPDM, Ethylene-Propylene-DieneMonomer ), putting the clamping part 1 into a hot air vulcanization box, and vulcanizing the outer surface 6 at a temperature of 280°C;

[0039] III. Adhesively coating the outer decoration layer 4 on the outer surface 6 of the clamping part 1 after vulcanization: the outer decoration layer 4 is sheet-like, and the material of the outer decoration layer 4 is thermoplastic elastic body (that is, TPE, thermoplastic elastomer), in this embodiment, the thermopl...

Abstract

The invention provides a sealing strip for the door frame of an automobile and a manufacturing process thereof. The sealing strip comprises a clamping part and a sealing part connected with the clamping part, wherein an exterior trimming layer is arranged on the outer surface of the clamping part, which is close to the interior part of the automobile, and bonded and coated with the exterior trimming layer. The manufacturing process comprises the following steps: (1) vulcanizing the outer surface of clamping part of the molded sealing strip body, which is exposed to the interior part of the automobile; and (2) bonding and coating the vulcanized outer surface with the exterior trimming layer. The sealing strip and the manufacturing process thereof provided by the invention has the advantagesof fewer steps, short production line, high production efficiency, low energy consumption, small production area, clean and pollution-free production and low rejection rate.

Description

technical field [0001] The invention relates to the technical field of automobile parts processing, in particular to an automobile door frame sealing strip and a manufacturing process thereof. Background technique [0002] The car door frame seal is a kind of car sealing parts, which is installed on the edge of the car door frame to seal the gap between the car door and the car door frame. The cross-sectional structure of the automobile door frame sealing strip is as follows: figure 1 As shown, it mainly includes a weather strip body, and the weather strip body includes a clamping part 1 and a sealing part 2; wherein the clamping part 1 is used to fix the automobile door frame sealing strip on the door frame of the automobile door; the sealing part 2 is located at the One side of the locking part 1 is connected with it, and is used for sealing the gap between the door and the door frame after the door is closed tightly. In order to prevent the automobile door frame sealing...
