[0025] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0026] Embodiment 1:
[0027] A sun protection car cover, comprising a car cover body, such as Figure 1As shown, the car cover body comprises a self-cleaning coating 1, a textile fabric layer 2, a first thermal insulation layer 3, a second thermal insulation layer 4 and a polyester fabric layer 5; the self-cleaning coating 1 is arranged on the outer surface of the textile fabric layer 2, and the inner side of the textile fabric layer 2 is sequentially provided with the first thermal insulation layer 3, the second thermal insulation layer 4 and the polyester fabric layer 5.
[0028] The textile fabric layer can be a polyester layer, a nylon layer, a spandex layer and an aramid layer, and the thickness is 0.3-2mm, which mainly plays a protective role of waterproofing, moisture-proofing and scratch-proofing for the inner layers.
[0029] The sprayed self-cleaning coating 1 has a hydrophobic angle of more than 130°, has a strong anti-staining and self-cleaning ability, and can keep the car cover clean. The main components of the self-cleaning coating used are 100-300 parts of silica aerogel, 5-10 parts of curing agent, 50-100 parts of film-forming agent, 10-20 parts of film-forming aid, 0.8-1.5 parts of emulsifier, 0.5-1 part of dispersant and 0.05-1 part of defoaming agent. The film-forming agent used is water-based epoxy resin, the curing agent is polyamide resin, the film-forming aid is propylene glycol butyl ether, the emulsifier is TEGO CARE 165, the dispersant is SN-5040, and the defoaming agent is AGITAN P 841.
[0030] When spraying the self-cleaning coating 1, the curing agent, the film-forming agent, the film-forming aid, the emulsifier, the dispersant and the defoaming agent are mixed uniformly and sprayed on the outer surface of the textile fabric layer 2, and then the silica aerogel powder with a particle size of 5-100μm is uniformly scattered on the surface of the formed base layer. After complete curing, the self-cleaning coating 1 with a thickness of 0.01mm-0.3mm is formed on the outer surface of the textile fabric layer 2. The protruding silica aerogel powder on the surface of the self-cleaning coating 1 can form a lotus leaf-like surface, and combined with the hydrophobicity of the silica aerogel powder itself, the surface of the self-cleaning coating 1 can have superhydrophobicity, thereby having self-cleaning ability.
[0031] In addition, the surface of the self-cleaning coating 1 is covered with silica aerogel powder, which can produce a certain heat insulation effect of the self-cleaning coating 1.
[0032] The two thermal insulation layers can effectively insulate the heat outside the car cover. In this embodiment, the first thermal insulation layer 3 is an aerogel coating, which is formed by spraying aerogel coating. The thickness is usually 1mm-5mm, and the specific thickness is determined according to the actual situation. The second thermal insulation layer 4 is an aerogel fiber layer, and the thickness is 1mm-10mm. The aerogel fiber layer is a product obtained by adding fibers as reinforcing bodies into the preparation process of aerogel.
[0033] The polyester fabric layer 5 is close to the vehicle body and can protect important parts such as the outer paint and headlight shell of the vehicle, avoiding being scratched by other structural layers of the car cover.
[0034] In preparation, first spray the aerogel coating on the aerogel fiber layer of a certain thickness to make it into an aerogel coating of 1mm~5mm thickness, then stitch the aerogel fiber layer of the coated aerogel coating with the polyester fabric layer 5 together, finally attach the textile fabric layer 2 of the spray self-cleaning coating 1 on the aerogel coating, and finally heat-press to obtain the sun-proof car cover. The sun-proof car cover obtained by the present application can be cut arbitrarily to suit different types of vehicles.
[0035] In order to realize the fixation of the sun-proof car cover, the magnetic buckle 7 or other adsorbing fixation structure can be arranged only on the top of the sun-proof car cover, or the elastic rope 8 or other tightening structure can be arranged only on the lower part of the sun-proof car cover, or the corresponding structure can be arranged on the top and lower part of the sun-proof car cover to double reinforce the sun-proof car cover, so as to cope with sudden severe weather. In the embodiment, the elastic rope 8 is arranged on the lower part and the magnetic buckle 7 is arranged on the top as an example for display, as shown in Figure 2 The magnetic buckle is located in the middle and plays a role in adsorbing to the vehicle body to fix the sun-proof car cover, and the elastic rope 8 on the lower part plays a role in tightening.
[0036] When the tightening structure used on the lower part of the sun-proof car cover is the elastic rope 8, the elastic rope 8 can be directly placed in place during the preparation of the sun-proof car cover and then sewn, or the elastic rope 8 can be sewn after the preparation of the sun-proof car cover is completed, and it is not limited to the specific arrangement manner. As long as the tightening can be realized, it is acceptable. Of course, the magnetic buckle can also be used as the tightening structure. The strong magnetic buckle is placed on the lower part of the prepared sun-proof car cover at intervals of 10cm and then sewn and fixed. The magnetic buckle structure arranged on the lower part of the sun-proof car cover is the same as the magnetic buckle structure arranged on the top, but the roles played by them are not exactly the same. The magnetic buckle on the lower part not only can fix the sun-proof car cover by adsorbing to the vehicle body, but also can play a role in tightening the lower part of the sun-proof car cover. The magnetic buckle on the top only plays a role in adsorbing and fixing. Figure 2 The top magnetic buckle 7 is sewn in the middle.
[0037] Embodiment 2
[0038] A sun-proof car cover, a first heat insulation layer is provided with a thickened area, the thickened area is determined according to the position of the vehicle, and the thickened area can be formed by thickening and spraying at the positions corresponding to the front window and the sunroof of the vehicle, that is, a basic aerogel coating is first formed, and then the thickened area is formed by spraying at the positions corresponding to the front window and the sunroof of the vehicle, so as to enhance the heat insulation capacity. The rest is the same as in Embodiment 1.
