Problems solved by technology

But in some cases, this traditional structure is difficult to achieve sufficient sealing function, for example, when the vehicle speed is high, the external air pressure may exceed the maximum sealing force provided by the sponge body, thus causing seal failure

Abstract

The invention provides a method for manufacturing a nano-modified environmentally friendly two-color sealing strip, which is composed of light-colored rubber strips, black rubber strips, sponge rubber strips and a steel belt skeleton in four-in-one combination. The light-colored part of the sealing strip of the invention has stable yellowing resistance, no release of harmful gas nitrosamines, half of the cost, no dust in the production process, and clean production. The products can be widely used in door frames and windows of middle and high-end cars.

Description

technical field [0001] The invention relates to a sealing strip for automobiles, in particular to a composite door frame sealing strip for automobiles. Background technique [0002] With the rapid development of my country's automobile industry, rubber seals for automobile door frames have become a hot spot in the market. Automotive sealing strips mainly play the role of sealing, shock absorption and decoration. Specifically, automotive seals can effectively prevent harmful substances such as wind, rain, and dust from intruding into the car, reduce the vibration generated by doors, windows and other parts of the car during driving to maintain the comfort and cleanliness of the car, and make the The working environment of the sealing part or device is improved, and the working life is extended. According to the current annual output of China's automobiles, the demand for China's automobile sealing strips exceeded 180 million meters in 2008, and will exceed 250 million meter...
