Abstract

The invention relates to an automobile fabric fender and a preparation method thereof, belonging to the technical field of preparation of automobile exterior decorations. Made of needle-punched blanket, the density of the needle-punched blanket is 900-1200g / m2, and the needle-punched blanket contains 40-50 parts by weight of low-melting fiber, 10-15 parts by weight of hollow fiber, 40-50 parts by weight Polyester fiber, the low melting point fiber is low melting point fiber of modified PET, the melting point is 110~120°C, and the hollow fiber is hollow PET fiber. It is prepared through fiber mixing, carding, fiber web needle punching, drying and softening treatment, pressing and water jet cutting. The preparation method of the invention is simple, the cost is low, and the prepared automobile fabric fender is light in weight, high in strength, good in sound absorption effect, environmentally friendly, and can be recycled and reused.

Description

technical field [0001] The invention relates to an automobile fender and a preparation method thereof, in particular to an automobile fabric fender and a preparation method thereof, and belongs to the technical field of preparation of automobile exterior decorations. Background technique [0002] Car fenders are generally used to install around the wheels of cars or at the bottom of the car, mainly to block the splash of sediment and accumulated water and keep the car body clean. At present, automobile fenders are mainly made of rubber and engineering plastics. Most of the existing products have large volume, are prone to warping and deformation, are heavy in weight, generate large noise, or have complex preparation processes. As automobile manufacturing safety, energy saving, comfort, and environmental protection have become the themes of development, the development of sturdy, lightweight, non-polluting, and noise-reducing auto parts has attracted the attention of major a...
