Abstract
The invention relates to an automotive engine firewall with a soundproof and heat-insulation performance. The automotive engine firewall comprises a wallboard which is identical with an automotive engine in shape and made of rubber materials. The automotive engine firewall with the soundproof and heat-insulation performance is characterized in that a polyurethane foaming layer is covered on the outer side of the wallboard. The automotive engine firewall with the soundproof and heat-insulation performance has the advantages of high soundproof and heat insulation performance, wide application range and low manufacturing cost.
Description
Technical field
The present invention relates to a kind of protection work, is for the fire-wall with sound insulation, heat-shielding performance on the motor car engine specifically.
Background technique
As everyone knows, in auto industry field, motor occupies very important position, and it is the important core parts of any type automobile, so the development of motor is also promoting the development of automotive industry.Along with the development of science and technology and improving constantly of human demand, engine for automobile has also experienced very long development route, and its Main Trends of The Development is exactly to advance towards the target of high power, low discharge capacity.Yet, high power, low discharge capacity just mean that the combustion efficiency of combustion medium (mainly referring to gasoline, diesel oil) in motor will improve, the raising of combustion efficiency just means that noise and the temperature of motor in running all can raise, the rising of noise pollutes the environment, and the rising meeting of temperature is so that heat is constantly taken the space conduction in car, thereby cause the travelling comfort of taking the space in the car to reduce, also may cause the security incidents such as spontaneous combustion, blast simultaneously.Do not expect also that the mankind better way fundamentally reduces in the situation of the noise of motor, temperature, the motor fire-wall is installed between engine hood and the motor as a kind of facility of remedying, and can play certain sound insulation, effect of heat insulation.
The wallboard of traditional vehicular engine fire-wall can be made by metal, pottery or flame resistance rubber, and wherein, the fire-wall of being made wallboard by flame resistance rubber has low cost of manufacture, good toughness and tolerance intensity high owing to it, is widely used.Because flame resistance rubber itself just possesses certain sound insulation, heat-shielding performance, therefore, only need that flame resistance rubber is carried out sulfidization molding according to profile, the structure of motor and just formed required fire-wall.But, because sound insulation, heat-shielding performance that rubber itself has are very limited, under the demand for development of vehicular engine high power, low discharge capacity (heat that is the engine body generation is large, noise is high), it has been difficult to satisfy people's demand, and this has just limited its using scope.For this problem, the improvement scheme has also been proposed in the prior art, be exactly the outer side surface covering one deck acoustical cotton at this rubber wallboard.Yet the manufacturing process of acoustical cotton is comparatively complicated, and need to be bonding by other material between itself and wallboard, and this meeting is lost more than gain so that the manufacture cost of rubber fire-wall significantly increases.
Summary of the invention
The problem to be solved in the present invention provides a kind of vehicular engine fire-wall with sound insulation, heat-shielding performance, and this fire-wall has higher sound insulation, heat-shielding performance, and using scope is wider, and its manufacture cost is lower.
For addressing the above problem, take following technological scheme:
Vehicular engine fire-wall with sound insulation, heat-shielding performance of the present invention comprises wallboard, and its shape is consistent with the profile of vehicular engine, and this wallboard is made by rubber material.The outer side surface that is characterized in described wallboard is coated with one deck polyurethane foaming layer.
The further improvement of the present invention scheme is that the inner side surface of described wallboard also is coated with one deck polyurethane foaming layer, can reduce the heat that conducts to wallboard like this, slows down ageing of rubber speed, improves the working life of this fire-wall.
Take such scheme, have the following advantages:
Because the outer side surface of the wallboard of the vehicular engine fire-wall with sound insulation, heat-shielding performance of the present invention is coated with one deck polyurethane foaming layer, polyurethane foaming layer can use foamed and sprayed device directly polyurethane adhesive to be sprayed on wallboard inside and get final product, polyurethane adhesive inside after the spraying exists countless tiny spaces, can realize the sound-absorbing effect close with acoustical cotton, have higher sound insulation, heat-shielding performance, the motor that can be fit to various vehicles uses, and its technique is very simple, and manufacture cost is lower.
Description of drawings
Fig. 1 is the structural representation with vehicular engine fire-wall of sound insulation, heat-shielding performance of the present invention;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the vehicular engine fire-wall with sound insulation, heat-shielding performance of the present invention comprises wallboard 1, and its shape is consistent with the profile of vehicular engine, and this wallboard 1 made by rubber material, and normally used rubber material is flame resistance rubber.The outer side surface of described wallboard 1 is coated with one deck polyurethane foaming layer 2.In the present embodiment, the shape approximation of described wallboard 1 is in the shape of man's carnival hat, and its crown partly is used for covering motor, the brim of a hat partly be used for and engine hood and vehicle frame between fixing.
In order to reduce the heat that conducts to wallboard, slow down ageing of rubber speed, improve the working life of this fire-wall, present embodiment also is coated with one deck polyurethane foaming layer 2 at the inner side surface of described wallboard 1.
During use, vehicular engine fire-wall with sound insulation, heat-shielding performance of the present invention is installed between automotive hood and the motor, can be good at reducing motor heat to the interior space conduction in running, reduce the noise pollution of interior space, thereby provide good comfortable by bus environment for the passenger.
