Zinc-steel fence connecting piece with surfaces sprayed with graphene coating

Abstract

A zinc-steel guardrail connector whose surface is sprayed with a graphene coating is characterized in that the prepared graphene coating suitable for the zinc-steel guardrail connector is applied on the outer surface of the zinc-steel guardrail connector or on the outer surface of the guardrail combined with the connector, Or the inner and outer surfaces of the connector, spray/brush the graphene coating with a thickness of 12µm±; for the connector that has been combined with the guardrail and is in use, spray the graphene paint with a thickness of 12µm± on its outer surface, or The outer surface of the combined guardrail is sprayed with a graphene coating with a thickness of 12µm±; for the new connecting piece that has not been combined with the guardrail, a graphene coating with a thickness of 12µm± is sprayed on the inner and outer surfaces; after testing, the thickness of the coating is only 12µm Under the condition of ±, a number of technical performances are superior to the existing surface-sprayed zinc-steel guardrail connectors.

Description

technical field [0001] This patent relates to the technical field of building protective facilities, in particular to a zinc-steel guardrail connector whose surface is sprayed with graphene paint. Background technique [0002] The surface of the existing zinc-steel guardrail connectors mostly adopts electrostatic spraying technology, spraying plastic on the surface, such as spraying polyester powder layer, to improve its safety and anti-corrosion performance. However, in the coastal areas of the South China Sea, such as Hainan, affected by the high temperature, high humidity and high salt fog marine monsoon, the zinc steel guardrails have not been used for a long time, especially the strong columns, crossbars and railings. Corrosion is full of rust, not only Therefore, it is necessary and important to improve the surface anti-corrosion treatment technology of zinc-steel guardrail connectors under harsh weather conditions; [0003] Graphene is a new carbonaceous material wit...
