[0032] This disclosure will be more readily understood by referring to the following description, taken in conjunction with the accompanying drawings and examples, all of which form part of this disclosure. It should be understood that this disclosure is not limited to the specific products, methods, conditions, or parameters described and / or illustrated herein. Furthermore, the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting, unless otherwise stated.

[0033] It should also be understood that, for clarity, certain features of this disclosure may be described herein in the context of individual embodiments, but may also be provided in combination with each other in individual embodiments. That is, unless obviously incompatible or specifically excluded, each individual embodiment is considered to be combinable with any other embodiment, and such combination is considered to represent another different embodiment. Conversely, for brevity, various features of this disclosure described in the context of individual embodiments may also be provided individually or in any sub-combination. Finally, while a particular embodiment may be described as part of a series of steps or part of a more general structure, each step or substructure may also be considered an independent embodiment in itself.

[0034] Unless otherwise stated, it should be understood that each individual element in the list and each combination of individual elements in the list will be interpreted as a different embodiment. For example, a list of embodiments denoted as "A, B, or C" should be interpreted as including embodiments "A", "B", "C", "A or B", "A or C", "B or C", or "A, B, or C".

[0035] In this disclosure, the singular forms of the articles “a,” “one,” and “the” also include the corresponding plural references, and references to a particular value include at least that particular value, unless the context clearly indicates otherwise. Thus, for example, a reference to “substance” is a reference to at least one of such substance and its equivalents.

[0036] Ordinal terms such as “first” and “second” may be used to describe various components or fluids, but these components and fluids are not limited by these terms. Therefore, without departing from the teachings of this disclosure, these terms are used only to distinguish one component / fluid from another.

[0037] When an item is described using the combined terms “...and / or ...", the description should be understood to include any one of the listed items and all combinations thereof.

[0038] Generally, the use of the term "about" indicates an approximation that can vary depending on the desired characteristics obtained from the disclosed subject matter and will be interpreted in a context-dependent manner based on function. Therefore, those skilled in the art will be able to interpret a degree of difference on a case-by-case basis. In some cases, the number of significant figures used when expressing a particular value can be a representative technique for determining the difference allowed by the term "about." In other cases, a gradient within a range of values ​​can be used to determine the range of differences allowed by the term "about." Furthermore, all ranges in this disclosure are inclusive and composable, and references to values ​​described within a range include every value within that range.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terms used herein and / or include any and all combinations of one or more of the associated listed items.

[0040] like Figures 1 to 4 As shown, the surface treatment and heat preservation device for the small-sized guardrail connector of this embodiment includes: a metal shell 11, which can be made of lightweight titanium alloy, magnesium alloy, aluminum alloy, etc.; a heat preservation chamber 12 placed in the shell 11, the heat preservation chamber 12 having a guardrail connector 121; a heating tube 13 placed in the heat preservation chamber 12, the heating tube 13 including a heating part 131 and a pin 132 connecting the heating part 131, the heating part 131 being located in the heat preservation chamber 12, the pin 132 extending downward to connect to an external power source (not shown in the figure); and a base 14 that cooperates with the shell 11.

[0041] In this embodiment, as Figure 4 As shown, the heating element 131 has a graphene coating 134 obtained by depositing a graphene film on its surface, which can heat small-sized annular guardrail connectors (e.g., connecting rings of crash barriers) in the insulation chamber 12. The aforementioned graphene coating can be prepared using various physical or chemical methods for combining metal materials with graphene. For example, Huang Linjun's team at Qingdao University added AgNO3 to a graphene oxide solution to prepare a graphene / silver nanocomposite film through co-precipitation; or Huang prepared a graphene-Cu composite film through pulse electrodeposition.

[0042] Combination Figure 1 As shown, the base 14 is provided with a conductive socket 141 that cooperates with the pin 132. The base can isolate the heating element from the power supply, which is beneficial to improving safety performance. The guardrail connector 121 is arranged around the inside of the heating element 131. The base 14 is provided with a rubber sealing ring 142, which can isolate the power supply (not shown in the figure).

[0043] Because the metal with a graphene coating heats up more uniformly, has a larger heating area, and heats up faster; at the same time, the thickness of the heating element 131 can be reduced without compromising other physical properties, making it lighter. Furthermore, this metal has excellent electrical conductivity, and can generate heat under low current operating conditions, thus providing a heat preservation function.

[0044] The "heating part 131" provided by this utility model mainly includes a body and a "graphene coating" as described above; the "body" mentioned herein is mainly considered to have excellent thermal conductivity, electrical conductivity and machinability, and there are no other particular limitations. For example, stainless steel (316L, etc.) can be used.

[0045] The "heating part 131" provided in this invention typically has a graphene coating with a thickness of 0.5-5.0 μm. This coating hardly affects the size of the heating part, while reducing the thickness of the heating part, thereby reducing the weight of the entire device and making it lightweight.

[0046] Furthermore, such as Figure 2 and Figure 3 As shown, the outer shell 11 has a cylindrical structure, and its outer wall is provided with a vent 111 that contacts the guardrail connector 121. After the small-sized guardrail connector is electroplated, a water film adheres to its surface, which needs to be heated. Therefore, the water film on the surface of the small-sized guardrail connector evaporates upon heating and can be discharged through the vent. The heating element 131 has a cylindrical structure, and several circumferential elongated through holes 133 are opened on its outer circumference to dissipate heat to the surroundings.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
