Description
Technical field
This utility model relates to auto parts machinery field, it is provided that a kind of heat insulating mattress for car engine chamber.
Background technology
Along with the development of society and improving constantly of living standard, automobile consumption the most more and more enters into the family of people
In the life of front yard.The statistical data announced according to middle vapour association, annual China automobile volume of production and marketing in 2015 be respectively completed 2450.33 ten thousand and
2459.76 ten thousand, increase by 3.25% and 4.68% the most respectively.Although this data speedup relatively previous year has slowed down, respectively
Decrease 4.01 and 2.18 percentage points, but the most continuous 3 years of China's automobile volume of production and marketing is more than 20,000,000 since 2013, and
The whole world first within continuous 7 years, is continued to hold a post or title with the achievement of whole world the new highest record in history in 2015.
Be required in the automobile engine indoor of traditional mode of production design heat insulating mattress, thus form thermal insulation layer, trap heat to
The radiation of bonnet, can not only protect bonnet lacquer painting, but also can effectively reduce the noise of electromotor.Future automobile industry
The trend of development is lightweight, but, current engine room heat insulating mattress is to pursue good performance and cannot realize lightweight
Requirement, therefore, it is quite necessary to develop the excellent heat insulating mattress of a kind of sound insulation, anti-acoustic capability to meet wanting of industry development
Ask.
Utility model content
Therefore, in order to solve the problem that prior art exists, this utility model provides a kind of for car engine chamber
Heat insulating mattress.
For solving this technical problem, this utility model takes below scheme: a kind of heat insulating mattress for car engine chamber,
Including nonwoven fabric base sheet material layers, above described nonwoven fabric base sheet material layers, it is bonded with an aeroge carpet veneer by adhesive, described
The top of aeroge carpet veneer is bonded with a rock wool layer, and is bonded with a glass cotton layer above described rock wool layer, at described glass
The top of glass cotton layer is bonded with an aluminium foil layer, and is the most uniformly coated with an infrared barrier between described glass cotton layer and aluminium foil layer
Layer.
Improve further: described aeroge carpet veneer is the aeroge carpet veneer of hard platy structure.
Improve further: the thickness of described aeroge carpet veneer is 2.0-3.5mm.
Improve further: the thickness of described glass cotton layer is 2.3-4.5mm.
Improve further: described infrared barrier layer includes nano oxidized tin dope cadmium oxide coating.
By using preceding solution, the beneficial effects of the utility model are: the spy of this utility model each level order
Different design draws through repetition test, is not simple superposition, and this heat insulating mattress uses aerogel blanket, rock wool and glass cotton to make
For main material, these materials not only possess heat insulation, the anti-acoustic capability of excellence, and density is low, extremely meets future automobile light
The requirement quantified, the heat conductivity under wherein the density of aerogel blanket is 180 ~ 220kg/m, room temperature has then reached 0.018W/
(K m), its effect of heat insulation is 2-5 times of traditional insulation materials, the nano oxidized tin dope cadmium oxide coating additionally designed,
Its near-infrared rejection rate that wavelength is less than 1200nm reaches 85%, can effectively intercept near infrared ray, prevents heat radiation from damaging engine
Lid lacquer painting.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
With reference to Fig. 1, this utility model embodiment discloses a kind of heat insulating mattress for car engine chamber, including nonwoven fabric base
Sheet material layers 1, is bonded with an aeroge carpet veneer 2 by adhesive above described nonwoven fabric base sheet material layers 1, described in the present embodiment
Aeroge carpet veneer 2 is the aeroge carpet veneer of hard platy structure, can play plastotype effect, and the most described aeroge
The thickness of carpet veneer 2 is 2.4mm, in actual production, as long as the thickness of this aeroge carpet veneer 2 all can be implemented between 2.0-3.5
The purpose of this utility model, is bonded with a rock wool layer 3 above described aeroge carpet veneer 2, and above described rock wool layer 3
Being bonded with a glass cotton layer 4, the thickness of the most described glass cotton layer 4 is 2.8mm, in actual production, and this glass cotton
As long as the thickness of layer 4 all can implement the purpose of this utility model between 2.3-4.5, viscous above described glass cotton layer 4
Conjunction has an aluminium foil layer 5, and is the most uniformly coated with an infrared barrier layer 6 between described glass cotton layer 4 and aluminium foil layer 5, in this reality
Execute infrared barrier layer described in example 6 directly to use nano oxidized tin dope cadmium oxide paint uniformly to coat to form, can effectively hinder
Every infrared ray.
By using preceding solution, the beneficial effects of the utility model are: the spy of this utility model each level order
Different design draws through repetition test, is not simple superposition, and this heat insulating mattress uses aerogel blanket, rock wool and glass cotton to make
For main material, these materials not only possess heat insulation, the anti-acoustic capability of excellence, and density is low, extremely meets future automobile light
The requirement quantified, the heat conductivity under wherein the density of aerogel blanket is 180 ~ 220kg/m, room temperature has then reached 0.018W/
(K m), its effect of heat insulation is 2-5 times of traditional insulation materials, the nano oxidized tin dope cadmium oxide coating additionally designed,
Its near-infrared rejection rate that wavelength is less than 1200nm reaches 85%, can effectively intercept near infrared ray, prevents heat radiation from damaging engine
Lid lacquer painting.
