Description
Technical field
The utility model relates to a kind of automobile decoration sealing band and manufacture method thereof, especially a kind of lateral ledge sealing band and manufacture method thereof.
Background technology
The junction at a plurality of positions of automobile all is provided with sealing band, and the Main Function of weather strip for automobile is waterproof and dustproof, damping, sound insulation and sealing.Along with the development of science and technology and the reinforcement of people's environmental protection consciousness, more and more higher to the requirement of sealing band, except good leak tightness and environment isolation features, also require to have traveling comfort and ornamental, require that it is attractive in appearance, safety and environmental protection etc.
Exposing sealing band, such as window sealing strip, is sealing member, is again appearance ornamental pieces simultaneously; Wherein outer sealing strip for windowsills of automobiles also cut by chauffeur wind glass guide groove or water, be close to window lifting glass, the obstruct rainwater immerses, it is one of most important sealing band in the automobile sealed system, the lateral ledge sealing band is inlaid into the particularity that vehicle body need guarantee dimensional fits, reach the sealing antiseep, sound insulation, dustproof, the effect of damping and sealing, general this sealing band arranges colloid lip sheet along its length direction, also be pasted with cashmere-planted layer being close on the lip sheet of window lifting glass, flocking with the friction drag between adhesive tape, reduces in addition the beauty function that reaches of noise when can reduce glass lifting on being close to the lip sheet of window lifting glass.Present this class exposes sealing band and can be divided into two classes by its exposed face material, one class is that organic elastomer as weatherstrip body is directly as exposed face, its cross-sectional plane as shown in Figure 1, because the organic elastomer surface can not reach the effect of light at present, generally make dull surface, generally be used for low-grade car.Another kind of is to adopt corrosion-resistant steel bright wisp material, and simultaneously as skeleton, bright of corrosion-resistant steel is as exposed face in the general corrosion-resistant steel bright wisp embedding sealing bar body, its cross-sectional plane as shown in Figure 2, appearance effect is better, generally is used for the relatively high vehicle of class; Yet its forming process is comparatively complicated, and cost is higher, is 0.3mm～0.5mm because processing needs general corrosion-resistant steel bright wisp material thickness, and product design is heavier, is unfavorable for automotive light weight technology.
