Abstract

The utility model relates to a mixed-density polypropylene pedal pad and belongs to the field of production of automobile parts. A non-woven fabric pedal is fixedly connected with a low-density polypropylene bottom plate; a high-density polypropylene protection plate is fixedly connected with the low-density polypropylene bottom plate; a sound-absorption cotton pedal bottom liner is positioned below the non-woven fabric pedal and is fixedly connected with the rear side of the low-density polypropylene bottom plate; a sound-absorption cotton protection plate bottom liner is positioned below the high-density polypropylene protection plate and is fixedly connected with the low-density polypropylene bottom plate. The mixed-density polypropylene pedal pad has the advantage of novel structure; a high-density part and a low-density part respectively meet requirements on high strength and light weight; the whole pedal pad meets the requirements on environment and safety; by virtue of sound-absorption cotton and non-woven fabric, the sound absorption performance and abrasion resistance of a product are improved.

Description

Hybrid density polypropylene stretcher liner

Technical field

The utility model belongs to the auto parts and components production field, refers in particular to a kind of stretcher liner.

Background technology

development along with auto trade, also produce a lot of new technology around automobile industry, new product, traditional stretcher cushioning product mostly is the renewable sponge compacting, or single polypropylene material moulding, renewable sponge product environmental-protecting performance, resistance to abrasion is difficult to reach client's requirement, the part of single polypropylene material product is difficult to again be strengthened, resistance to abrasion, sound absorption properties is also all as one wishes not to the utmost, along with people to safety, traveling comfort, durability, improving constantly of lightweight requirements, the stretcher cushioning product is around environmental protection, the local reinforcement, lightweight, wear-resisting, the important indicators such as sound-absorbing have been carried out new research and development.

Summary of the invention

The utility model provides a kind of hybrid density polypropylene stretcher liner, is difficult to reach the problem of client's requirement solve to pass stretcher liner environmental-protecting performance, resistance to abrasion, sound absorption properties.

The technical solution of the utility model is: the nonwoven fabrics pedal is fixedly connected with low close polypropylene base plate, the high density poly propylene backplate is fixedly connected with low close polypropylene base plate, acoustical cotton pedal end liner is positioned at nonwoven fabrics pedal below, and with the rear side of low close polypropylene base plate, be fixedly connected with, acoustical cotton backplate end liner is positioned at high density poly propylene backplate below, and with low close polypropylene base plate, is fixedly connected with.

The utility model has the advantage of: novel structure, high density has partly met high-intensity requirement, low-density part has reached the weight-saving requirement, the whole requirement that meets again environment and safety, and acoustical cotton, nonwoven fabrics have promoted product at sound-absorbing and wear resisting property.
