Description

Technical Field

[0001] The utility model relates to the technical field of automobile industry, in particular to an automobile roof cover made of integrated materials. Background Art

[0002] With the rapid development of the automobile industry, the car roof, as an important part of the car body, not only carries the function of protecting the passengers in the car from the external environment, but also is related to the appearance and comfort of the whole vehicle. Although the common car roof materials on the market have certain thermal insulation, corrosion resistance and UV protection capabilities, their performance is often affected in high temperature, humid or dusty environments, resulting in aging and damage of the roof. In addition, traditional roof materials perform poorly in sound insulation and noise reduction, affecting the driving and riding experience of passengers. Therefore, it is necessary to develop a new type of car roof to overcome the shortcomings of existing technical solutions. Utility Model Content

[0003] The utility model aims to provide an integrated material automobile roof to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated material automobile roof, comprising an automobile roof body, the automobile roof body consisting of an aluminum alloy substrate, an outer layer, an anti-corrosion layer, a sound absorption and noise reduction layer and a finishing layer, the surface of the aluminum alloy substrate is provided with an outer layer, the outer layer comprises a weather-resistant polymer material and a protective layer, the surface of the outer layer is provided with an anti-corrosion layer, the anti-corrosion layer comprises a polymer coating, a paint layer and a wax layer, the bottom of the aluminum alloy substrate is provided with a sound absorption and noise reduction layer, the sound absorption and noise reduction layer comprises a glass fiber layer and a mineral wool layer, the bottom of the sound absorption and noise reduction layer is provided with a finishing layer, the finishing layer comprises a polyethylene layer and an activated carbon layer.

[0005] The main body of the car roof adopts a multi-layer composite material structure, in which the aluminum alloy substrate is the basic component and has good structural strength. The outer layer has good protective performance and can protect the surface of the aluminum alloy substrate. The anti-corrosion layer is composed of a polymer coating, a paint layer and a wax layer. The polymer coating is a thin film composed of polymer materials, which can enhance the material's antioxidant, corrosion resistance, waterproof and UV resistance, protect and extend the service life of the basic material. The sound-absorbing and noise-reducing layer is composed of a glass fiber layer and a mineral wool layer, which is non-flammable and has excellent chemical resistance. It can also effectively block cold and hot bridges, thereby improving the thermal insulation effect and prolonging the sound wave in the fiber. The propagation path and time inside the spray coating increase the time for converting sound energy into mechanical energy, causing the sound wave energy to be sharply attenuated, so it has good sound absorption performance. The finishing layer is the layer that directly contacts the passengers in the car. Through the cooperation of the polyethylene layer and the activated carbon layer, it has excellent waterproof and isolation properties, strong corrosion resistance, and excellent thermal insulation properties, which can reduce heat energy loss. The activated carbon layer is a carbon material with a highly porous structure. The inner surface has good heat absorption and heat resistance, strong adsorption, and its pore size distribution is uniform and the pore size is moderate. It can fully absorb various organic compounds, heavy metals and other pollutants to reduce odor in the car.

[0006] Preferably, the protective layer is arranged on the surface of the weather-resistant polymer material, and the weather-resistant polymer material is an ASA modified material.

[0007] Weather-resistant polymer materials use ASA modified materials, which have excellent weather resistance, good mechanical and physical properties, and anti-static functions. They can reduce dust accumulation on the surface and will not gradually turn gray like specially treated aging-resistant ABS. Therefore, they are particularly suitable for automotive parts. The protective layer can use nano-coating to protect the surface of the weather-resistant polymer material.

[0008] Preferably, a paint layer is provided on the top of the polymer coating, and a wax layer is provided on the top of the paint layer.

[0009] Polymer coating is a technology that uses polymer materials to form a thin film and covers the surface of other base materials. It can enhance the material's anti-oxidation, corrosion resistance, waterproofness and UV resistance, protect and extend the service life of the base material. The paint layer and wax layer can use existing technology to further improve the protective performance of the car roof.

[0010] Preferably, the mineral wool layer is arranged on the surface of the glass fiber layer.

[0011] The glass fiber layer is a material composed of many extremely fine glass fibers. Glass fiber has the characteristics of high tensile strength and small elongation, which enables it to maintain stable performance under various stress conditions. At the same time, it has a high elastic coefficient and good rigidity, which enables it to exhibit good elastic behavior when subjected to pressure or tension. Secondly, glass fiber is an inorganic fiber, so it is non-flammable and has excellent chemical resistance. It can also absorb sound and reduce noise. The mineral wool layer is a material made of natural rock and artificial mineral fibers, which are melted, spun or blown into fibers at high temperature and then processed. The mineral wool layer has a good thermal insulation effect and can form a closed and seamless whole, effectively blocking cold and hot bridges, thereby improving the thermal insulation effect. At the same time, it can prolong the propagation path and time of sound waves inside the fiber spray layer, increase the time for sound energy to be converted into mechanical energy, and cause the sound wave energy to be sharply attenuated, so it has good sound absorption performance.

[0012] Preferably, the activated carbon layer is arranged on the surface of the polyethylene layer.

[0013] The polyethylene layer has excellent waterproof and isolation properties, strong corrosion resistance, and excellent thermal insulation properties, which can reduce heat energy loss. The activated carbon layer is a carbon material with a highly porous structure. The internal surface area has good heat absorption and heat resistance, strong adsorption, and a uniform pore size distribution. The pore size is moderate, and it can fully absorb various organic compounds, heavy metals and other pollutants to reduce odor in the car.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. The finishing layer in the utility model is the layer that directly contacts with the passengers in the car. Through the coordinated use of the polyethylene layer and the activated carbon layer, it has excellent waterproof and isolating properties, strong corrosion resistance, and excellent thermal insulation properties, which can reduce heat energy loss. The activated carbon layer is a carbon material with a highly porous structure, and the inner surface area has good heat absorption and heat resistance, strong adsorption, uniform pore size distribution, moderate pore size, and can fully adsorb various organic compounds, heavy metals and other pollutants to reduce odor in the car.

[0016] 2. The utility model adopts a multi-layer composite material structure, in which the anti-corrosion layer is composed of a polymer coating, a paint layer and a wax layer. The polymer coating is a thin film composed of polymer materials, which can enhance the material's anti-oxidation, corrosion resistance, waterproofness and UV resistance, and protect and extend the service life of the base material.
