Abstract
The utility model relates to a sound-proof pad of a composite structure and used on a car roof. The sound-proof pad is formed by hot press molding of multiple layers of sound-proof materials in a composite mode, wherein the layers of sound-proof materials are mutually bonded through binder layers, and the sound-proof pad is of a three-layer composite structure or a five-layer composite structure. Compared with the prior art, the sound-proof pad of the composite structure and used on the car roof can play a role in absorbing and attenuating noise, is quite good in heat insulation effect, and can enhance the structural strength of the car roof.
Description
Technical field
The utility model relates to a kind of automobile top sound insulating pad, especially relates to a kind of roof sound insulating pad of composite structure.
Background technology
The roof sound insulating pad of auto trade mainly comprises two kinds of structures: (1) most all thick material making parts of individual layer that adopt at present.Because the outside of preceding coaming plate is machinery space, driving engine can produce bigger noise when work, and noise is divided into high and low frequency two parts; The sound insulating pad that adopts single layer structure to make can play tangible absorption, attenuation to high frequency noise, and can only play the effect of partially absorbing to low frequency noise.(2) EPDM+ sound insulating pad composite structure: Heavy Weight cost height, complex process.The above-mentioned sound insulating pad overwhelming majority does not all have the effect of enhancing to roof.
The utility model content
The purpose of this utility model is exactly to provide a kind of roof sound insulating pad that roof is had the composite structure of humidification for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of roof sound insulating pad of composite structure, through hot-forming compound obtaining, bonding through adhesive layer between each insulation material layer by the insulation material layer of multilayer.
Described roof sound insulating pad is three-layer composite structure, and two-layer up and down is the layers of kraft paper that film is drenched on the surface, and interlayer is the high density polyurethane insulation material layer.
Described roof sound insulating pad is five layers of composite structure, and interlayer is the low-density polyurethane insulation material layer, and upper strata and lower floor are the nonwoven fabrics that film is drenched on the surface, between nonwoven fabrics and the polyurethane body insulation glass carpet veneer are set.
Described high density polyurethane insulation material layer is density 50kg/m
3Polyurethane semihard foam.
Described low-density polyurethane insulation material layer is density 30kg/m
3Polyurethane semihard foam.
Described adhesive layer is polyurethane binder layer.
Compared with prior art, the utility model adopts the multiple-structure composite molding of 8mm high density polyurethane foaming layer and surperficial craft paper or nonwoven fabrics, when playing absorption, attenuation facing to the noise in the car, can also play the effect of skeleton.
