Detailed Description
The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.
As shown in the attached drawing, the carbon fiber resin composite heat insulation film comprises an adhesive layer 1, a heat insulation layer 2, a light reflection layer 3, a photosensitive layer 4 and a protective layer 5 which are sequentially stacked.
The adhesive layer 1 is composed of a transparent acrylic foam adhesive tape, the acrylic foam adhesive tape is made of transparent materials and is composed of a high-density acrylic foam base material and an acrylic back adhesive, the adhesive layer has excellent adhesive strength and good sealing performance, can replace traditional mechanical connection modes such as riveting and welding to play a role in structure fixing, is uvioresistant and solvent-resistant, can be used for adhering structures of various materials and multiple scenes, and does not leave adhesive marks on the surface of an object when torn off. Utilize the cotton sticky tape of transparent acrylic acid bubble as the bonding surface in this scheme, provide good bonding effect and can do not have the residue to get rid of simultaneously.
The material of insulating layer 2 is carbon fiber resin composite, compares in the common PET of prior art and PVC material and makes insulating layer 2, and carbon fiber resin compound insulating layer 22 possesses outstanding heat resistance (can bear the high temperature of 2000 ℃ or more), thermal shock resistance, low coefficient of thermal expansion, possesses the operating requirement under extreme environment.
Specifically, the carbon fiber is an inorganic polymer fiber containing carbon in an amount of more than 90%. Wherein the carbon content is more than 99 percent, namely graphite fiber. The layer structure of graphite is mainly arranged and extended along the direction of the carbon fiber filament. Therefore, the carbon fiber material has good electric and heat conducting performance in the direction of the carbon fiber filament. Because the thermal conductivity of the material has anisotropy, the thermal conductivity and the electric conductivity are reduced by many times in the direction vertical to the filaments, and the heat insulation effect is achieved.
The carbon fiber composite material is a porous structure formed by weaving and molding fibers as a heat insulation material, the fiber filaments are mainly distributed in a plane, and few fibers are arranged in the Z direction vertical to the plane, so that the heat insulation performance of the carbon fiber product with the structure along the direction vertical to the plane is better. The carbon fiber composite material is generally used in the high-temperature field, and the heat resistance of the carbon fiber composite material is far superior to that of other conventional heat-insulating materials.
The light reflection layer 3 includes a base layer and reflection units 31 uniformly distributed on the base layer, and the main material of the reflection units 31 is aluminum foil. The light reflecting layer 3 can reduce the luminousness to a certain extent, consequently the utility model discloses the weapon has all covered light reflecting layer 3, but reflects through the light reflection unit 31 that sets up evenly distributed, guarantees the luminousness when improving the reflectivity.
The photosensitive layer 4 includes a base layer and a photochromic material coated on the base layer, the photochromic material including a light absorber, an antioxidant, a heat stabilizer and an inhibitor. The light absorber is mainly made of silver halide materials, can generate various dark color discoloring effects under the irradiation of strong sunlight and ultraviolet rays, and can recover to the initial color without the irradiation of the sunlight or the ultraviolet rays, so that the heat insulation film can generate different discoloring effects by photosensitive discoloration. The heat insulation film is wholly under outdoor sunlight irradiation, when the sunlight irradiation is strong, the silver halide absorbs the light flat position dark color effect, the light transmittance is reduced, otherwise, the light color is reduced, and the light transmittance is increased.
The protective layer 5 is made of acrylic resin, and the upper surface of the protective layer 5 is also provided with anti-skid grains 51 and flow guide grooves 52. The anti-slip lines 51 increase the surface friction force, reduce the risk of slipping during maintenance, and the diversion trenches 52 facilitate the timely discharge of water. Preferably, the anti-slip threads 51 and the guide grooves 52 are communicated with each other.
The utility model discloses in set up photosensitive layer 4 in light reflection layer 3 top, shine to light before light reflection layer 3 and feed back sunshine, filter earlier when the highlight and absorb partial light and reflect again, be favorable to prolonging the life of light reflection layer 3. If the photosensitive layer 4 is provided separately, the color change effect of the photosensitive layer 4 alone is not enough to filter enough light to achieve the desired heat insulation effect, so the combined action of the photosensitive layer 4 and the light reflecting layer 3 is required to achieve the light blocking and reflecting effect.
Specifically, the heat insulation layer 2, the light reflection layer 3, the photosensitive layer 4 and the protective layer 5 are bonded together through an adhesive.
