Odorless automobile sealing strip and preparation method thereof

Abstract

The invention relates to an odorless automobile sealing strip is formed by compounding a dense rubber strip and a foamed rubber strip, and the dense rubber strip mainly comprises ethylene propylene diene monomer, reinforcing carbon black, environment-friendly oil, ground calcium carbonate, zinc oxide, stearic acid, a surfactant, bamboo fragrance, sulfur powder, an accelerant and a vulcanizing agent. The foamed rubber strip mainly comprises ethylene propylene diene monomer, reinforced carbon black environment-friendly oil, active calcium, zinc oxide, stearic acid, a processing aid, bamboo fragrance, sulfur powder, an accelerant, a vulcanizing agent, DTDM, DPTT and a foaming agent. According to the invention, ethylene propylene diene monomer (EPDM) is used as a main material, and a pluralityof added auxiliary materials and fragrance are interacted, so that the prepared automobile sealing strip is fragrant and free of pungent smell.

Description

technical field

[0001] The invention relates to the technical field of auto parts, in particular to an odorless automobile sealing strip and a preparation method thereof. Background technique

[0002] Automobile sealing strip is one of the important parts of automobiles. It is widely used in doors, windows, body, sunroof, engine box and backup (luggage) box and other parts. It has the functions of sound insulation, dustproof, water seepage prevention and shock absorption. Maintain and maintain the small environment in the car, thus playing an important role in protecting the members, electromechanical devices and accessories in the car. With the development of the automobile industry, the importance of the beauty, environmental protection and comfort of the sealing strip is becoming increasingly prominent.

[0003] At present, most of the automotive sealing strip materials are made of EPDM as the main raw material through vulcanization and cross-linking process, but H will b...
