Abstract
The utility model relates to a sound absorption product of an automobile. The sound absorption product comprises a product body; the product body is provided with a first material layer and a second material layer which are integrally welded with each other; and the first material layer is a non-woven fabric or an aluminum film, and the second material layer is a polypropylene or polyester microfiber layer. The sound absorption product has the advantages of excellent sound absorption performance and high-temperature resistance, low density, high cavity filling capacity and compressibility, and the like.
Description
Technical field
The utility model relates to a kind of auto-parts, particularly a kind of automobile sound absorbing products.
Background technology
By paper " PET Fibre-reinforced Polypropylene " as can be known, polypropylene and poly-ester fibres batch mixing are considered to a kind of novel high impact resistance polypropylene, and its advantage is to have improved stiffness and toughness.This class material has very large application potential aspect lightweight member, be the ideal material of automobile component.
At present, car conour has all become stream line pattern, the smooth connection of curved surface, and profile is very beautiful, but the car noise pollution problem is still a great problem.Sound is the vibrations due to body surface, and causes air molecule to move back and forth and produce.And automobile can directly affect occupant's comfort level at the noise of the middle generation of advancing, and accelerates people's fatigue, thereby improves accident rate.
The utility model content
The purpose of this utility model is to provide the high and low density of a kind of sound absorption qualities, fills out the automobile sound absorbing products that the chamber ability is strong, compressible performance is strong, high temperature resistant property is good.
The technical scheme that realizes the utility model purpose is: the utlity model has the goods body; Described goods body has welding all-in-one-piece the first material layer and the second material layer; Described the first material layer is nonwoven fabrics or aluminium film, and the second material layer is polypropylene and polyester microfiber layer.
Above-mentioned the first material layer and the second material layer are welded together by blowing and fusing a technology.
The utlity model has positive effect: (1) the utility model is simple in structure, can make according to the design needs of automobile the product of dimension; (2) the utlity model has the new energy of outstanding acoustic absorption, lightweight; (3) the utility model good heat-insulation effect improves the compartment comfort level, energy savings.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the cutaway view of A-A in Fig. 1.
The specific embodiment
See Fig. 1 and Fig. 2, the utlity model has and be designed to as required goods body 1 with holes or not with holes; Described goods body 1 has by blowing and fusing thread technology welding all-in-one-piece the first material layer 11 and second material layer 12; Described the first material layer 11 is nonwoven fabrics or aluminium film, and the second material layer 12 is polypropylene and polyester microfiber layer.
This product has the high and low density of sound absorption qualities, fills out the advantages such as the chamber ability is strong, compressible performance is strong, high temperature resistant property is good.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
