Abstract

The utility model discloses an automobile heat insulation and noise reduction water preventing film. The automobile heat insulation and noise reduction water preventing film comprises a water preventing film, wherein a heat insulation layer is arranged on one side of the water preventing film; a sound insulation layer is arranged between the water preventing film and the heat insulation layer; the water preventing film is fixedly connected with the sound insulation layer; and the sound insulation layer is fixedly connected with the heat insulation layer. The automobile heat insulation and noise reduction water preventing film is simple in structure, novel in design, low in cost and convenient to produce, the product dead-weight can be effectively reduced, and the effects of sound absorption and heat insulation are good; and three functions of heat insulation, noise reduction and water prevention can be taken into account, so that the water preventing film is relatively high in functionality and is suitable for being applied to various motor vehicles widely.

Description

Automobile heat insulation noise reduction dash film

Technical field

The utility model relates to automobile technical field, is specifically related to a kind of automobile heat insulation noise reduction dash film.

Technical background

Along with developing of automobile industry, people are more and more higher to the performance requriements of the travelling comfort of car and heat insulation, noise reduction and waterproof.

Automobile is in advancing, noise is mainly from two aspects, the noise that road surface and wheel effect are sent and the noise of driving engine, and the noise of automobile in advancing can make the people feel tired and carsick, make the probability of traffic accident increase, the requirement that therefore heat insulation noise reduction needs is very high.In the prior art, the heat insulation acoustic damping materials of general automobile mostly are some regeneration cottons or glass wool goods greatly, though these materials can play the effect of certain heat insulation noise reduction, its structure is all more single, heat insulation noise reduction is not very desirable, can't satisfy higher heat insulation noise reduction requirement.

In addition, the heat insulation acoustic damping materials dash performance of these automobiles is all relatively poor, and a slat gum bar, the one, waterproof are arranged between glass for vehicle window and the door outside sheet metal component, the 2nd, the position that keeps glass for vehicle window, this is that car door leaks, dust, a noise weak link into the car.Automobile dash film is installed in the arrangements for automotive doors, for the protection of the circuit normal operation in the arrangements for automotive doors, prevents that extraneous dust rainwater from entering, and prolongs the service life of spraying paint in the top layer.

Summary of the invention

At the shortcoming and defect that exists in the middle of the prior art, the purpose of this utility model is, a kind of automobile heat insulation noise reduction dash film is provided, and has better heat insulation, noise reduction and dash effect.

In order to realize above-mentioned task, the utility model is solved by the following technical solutions:

A kind of automobile heat insulation noise reduction dash film comprises the dash film, and a side of described dash film is provided with thermal insulation layer, between dash film and thermal insulation layer sound isolating layer is set, and wherein, dash film and sound isolating layer are fixed, and sound isolating layer and thermal insulation layer are fixed.

Compared with prior art, the utility model is simple in structure, modern design, and cost is low, is convenient to produce, and can effectively reduces the product deadweight, and sound-absorption and heat-insulation is effective; The utility model can heat insulation noise reduction dash three be taken into account, and is functional stronger, and all kinds of power actuated vehicles suit to be widely used in.

Description of drawings

Fig. 1 is cutaway view of the present utility model;

The implication of number in the figure: 1-dash film; 2-sound isolating layer; 3-thermal insulation layer;

The utility model is described in further detail below in conjunction with drawings and Examples.

The specific embodiment

Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.

Defer to technique scheme, as shown in Figure 1, a kind of automobile heat insulation noise reduction dash film, comprise dash film 1, a side of described dash film 1 is provided with thermal insulation layer 3, between dash film 1 and thermal insulation layer 3 sound isolating layer 2 is set, wherein, dash film 1 and sound isolating layer 2 are fixed, and sound isolating layer 2 and thermal insulation layer 3 are fixed.

In the present embodiment, dash film 1 adopts the PVC film, and the PVC film is to add functional processing aids such as plasticizer, stabilizer, lubricant in the polyvinyl chloride resin, and through the calendering film forming, general thickness is 0.08-02mm, has stronger resistance to effect of heat, toughness, ductility etc.Adopt this material as the dash film, can intercept the outer water and steam of car effectively, reach the excellent waterproof effect.

Sound isolating layer 2 car of can decaying effectively transmits the noise that produces with car body itself outward.Sound isolating layer 2 adopts the big glass wool of internal resistance to be pressed in the utility model, and glass wool belongs to a classification in the glass fibre, is a kind of manmade inorganic fibre.Adopting natural big ores such as quarz sand, limestone, dolomite is primary raw material, cooperates chemical such as some soda ash, borax to be melt into glass.Under melting state, get rid of into cotton-shaped fine fibre by the external force blowing produced, be grade separation between fiber and the fiber, be intertwined mutually, present many tiny gaps, have good thermal insulation, sound absorbing capabilities.

Thermal insulation layer 3 adopts the heat insulation material of GRC001 type aluminium foil to make, and this is a kind of new environment protection type heat insulating warm material, and this material softness, light being easy to are installed.This material structure is aluminizer and polyethylene, forms through machine up, not only has good insulation performance, heat reflection, heat insulation, counter radiation function, and can also play fine protection against the tide, insulation effect.

By hot melt glue dash film 1, sound isolating layer 2 and thermal insulation layer 3 are bonded together successively, namely can be made into the utility model.The utility model can heat insulation noise reduction dash three be taken into account, and is functional stronger, and all kinds of power actuated vehicles suit to be widely used in.

Claims

1. automobile heat insulation noise reduction dash film, comprise dash film (1), it is characterized in that, one side of described dash film (1) is provided with thermal insulation layer (3), between dash film (1) and thermal insulation layer (3), sound isolating layer (2) is set, wherein, dash film (1) and sound isolating layer (2) are fixed, and sound isolating layer (2) and thermal insulation layer (3) are fixed.
