Description

Technical Field

[0001] The utility model relates to the technical field of high-speed train windshields, in particular to a high-speed train windshield. Background Art

[0002] The high-speed train windshield is an important component of the high-speed train. It can effectively reduce the noise generated by the vehicle during operation, provide passengers with safety and comfort, and at the same time reduce the resistance of the high-speed train during operation.

[0003] In the related technology, high-speed trains currently usually use rubber windshields of an elastic polyester system. During the operation of high-speed trains, the surface of the rubber windshield is subjected to the effects of external factors such as heat, oxygen, light, mechanical force, radiation, chemical media, and ozone in the air for a long time, causing chemical changes in its macromolecular chains, destroying the original chemical structure of the rubber. The windshield surface is easily penetrated by gas or liquid, resulting in the rubber windshield having deteriorating performance such as color bleeding, deformation, brittleness, hardening, cracking, mildew, gloss loss, and color change, which seriously affects the appearance and product quality of high-speed trains. Generally, the windshield needs to be maintained or replaced after about three months of operation, which greatly increases the cost of use. Utility Model Content

[0004] The purpose of the utility model is to provide a high-speed train windshield to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-speed train windshield, comprising:

[0007] A windshield body, wherein the outer surface of the windshield body is provided with a first fluororubber coating, and the inner surface of the windshield body is provided with a second fluororubber coating;

[0008] A third fluororubber coating is disposed on the first fluororubber coating, and a fourth fluororubber coating is disposed on the second fluororubber coating.

[0009] The high-speed train windshield according to this solution has at least the following technical effects:

[0010] The high-speed train windshield is provided with a first fluororubber coating on the outer surface of the windshield body and a second fluororubber coating on the inner surface of the windshield body, so that a fluororubber protective coating is formed on the inner and outer surfaces of the windshield body, and a third fluororubber coating is provided on the first fluororubber coating, and a fourth fluororubber coating is provided on the second fluororubber coating. The two layers of fluororubber coating on the inner and outer surfaces of the windshield body can effectively prevent the penetration of gas and liquid on the inner and outer surfaces of the windshield body, avoid the deposition and penetration of pollutants to the inner and outer surfaces of the windshield body, prevent the windshield body from aging, losing gloss and turning yellow, improve the weather resistance, corrosion resistance and air tightness of the windshield body, extend the service life of the windshield body, reduce the maintenance or replacement of the windshield body, reduce the cost of use, and enable the high-speed train to maintain a good appearance and product quality.

[0011] As a further solution of the present invention: the thickness of the first fluororubber coating is equal to that of the third fluororubber coating, and the thickness is 0.04mm-0.06mm.

[0012] Since the thickness of the first fluororubber coating and the third fluororubber coating are equal, both of which are 0.04mm-0.06mm, the equal thickness ensures the uniformity of the first fluororubber coating and the third fluororubber coating on the outer surface of the windshield body, avoiding local fragility or performance differences caused by uneven thickness of the fluororubber coating, and ensuring that the outer surface of the windshield body has a consistent protective effect under various environmental conditions.

[0013] As a further solution of the present invention: the thickness of the second fluororubber coating is equal to that of the fourth fluororubber coating, and the thickness thereof is both 0.04 mm-0.06 mm.

[0014] Since the thickness of the second fluororubber coating and the fourth fluororubber coating are equal, both of which are 0.04mm-0.06mm, the equal thickness ensures the uniformity of the second fluororubber coating and the fourth fluororubber coating on the inner surface of the windshield body, avoiding local fragility or performance differences caused by uneven thickness of the fluororubber coating, and ensuring that the inner surface of the windshield body has a consistent protective effect under various environmental conditions.

[0015] As a further solution of the present invention: the first fluororubber coating, the second fluororubber coating, the third fluororubber coating and the fourth fluororubber coating are all independently selected as airtight coatings.

[0016] Since the first fluororubber coating, the second fluororubber coating, the third fluororubber coating and the fourth fluororubber coating are all independently selected as airtight coatings, the overall airtightness of the windshield can be significantly enhanced through the combination of multiple independent airtight coatings, which can more effectively prevent gas and liquid penetration, thereby improving the performance and durability of the windshield. At the same time, multiple protections can be provided for the windshield body. Even if one layer of the fluororubber coating is locally worn or damaged, the other layer of the fluororubber coating can still continue to provide airtight protection, reducing the risk of failure of a single layer of fluororubber coating.

[0017] As a further solution of the present invention: the first fluororubber coating, the second fluororubber coating, the third fluororubber coating and the fourth fluororubber coating are independently selected from tetrafluoroethylene and hydrocarbon propylene copolymer layers.

[0018] Since the first fluororubber coating, the second fluororubber coating, the third fluororubber coating and the fourth fluororubber coating are all independently selected from tetrafluoroethylene and hydrocarbon propylene copolymer layers, the model of the tetrafluoroethylene and hydrocarbon propylene copolymer is fluororubber TP, the fluororubber coating can maintain stable physical properties under high temperature environment, is not easy to age or degrade, and can effectively prevent the penetration of gas and liquid, thereby providing better protection for the windshield body and extending the service life of the windshield body.

[0019] As a further solution of the utility model: a zirconium oxide layer is respectively provided on the third fluororubber coating and the fourth fluororubber coating.

[0020] By respectively arranging a zirconium oxide layer on the third fluororubber coating and the fourth fluororubber coating, the wear resistance of the inner and outer surfaces of the windshield body can be effectively improved, and the wear caused by the impact of sand, rain or other particles can be reduced. The corrosion resistance of the fluororubber coating can be further enhanced to protect it from damage by environmental factors. At the same time, the performance stability of the fluororubber coating under high temperature conditions can be improved, and the impact of high temperature on the fluororubber coating can be reduced, thereby further improving the durability of the windshield body and ensuring its long-term stable use effect.

[0021] As a further solution of the utility model: the thickness of the zirconium oxide layer is 10nm-100nm.

[0022] Since the thickness of the zirconium oxide layer is 10nm-100nm, the 10nm-100nm zirconium oxide layer has good optical properties and can effectively reduce the scattering and reflection of light, so that the windshield body maintains a clear line of sight and reduces visual fatigue. In addition, the appropriate thickness of the zirconium oxide layer can better provide effective protection for the fluororubber coating and extend its service life, thereby extending the service life of the windshield body.

[0023] As a further solution of the utility model: the density of the zirconium oxide layer is 5.89g / cm 3 -6.1g / cm 3 .

[0024] Since the density of the zirconium oxide layer is 5.89 g / cm 3 -6.1g / cm 3 , which can enhance the stability of the zirconia layer under high temperature conditions and reduce the impact of thermal stress on the fluororubber coating. The high density of the zirconia layer can effectively prevent gas and liquid penetration, thereby improving the overall air tightness of each coating. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Specifically, since the first fluororubber coating 102, the second fluororubber coating 103, the third fluororubber coating 104 and the fourth fluororubber coating 105 are independently selected as airtight coatings, the overall airtightness of the windshield can be significantly enhanced through the combination of multiple independent airtight coatings, which can more effectively prevent gas and liquid penetration, thereby improving the performance and durability of the windshield.
