Reflective and anticorrosive coating of ceramic tile and preparation method of reflective and anticorrosive coating

Abstract

The invention provides a reflective and anticorrosive coating of a ceramic tile. The reflective and anticorrosive coating is applicable to reflective and anticorrosive treatment of concrete crash barriers of highway bridges and has the advantages of being good in reflective and anticorrosive performance, not prone to falling, compact and attractive in appearance, environment-friendly and safe. The invention further provides a preparation method of the reflective and anticorrosive coating of the ceramic tile.

Description

Technical field [0001] The invention belongs to the technical field of road and bridge maintenance, and in particular relates to a ceramic tile reflective anti-corrosion coating for highway bridge concrete anti-collision guardrails and a preparation method thereof. Background technique [0002] Some highway bridge concrete guardrails need to be treated with reflection and anti-corrosion. Ordinary reflective materials do not have anti-corrosion function. The roots of concrete guardrails are eroded by rain, snow and snow-melting agents used for snow removal in winter. The concrete protective layer is prone to alkali corrosion and peeling off, resulting in exposed steel bars. It accelerates the corrosion rate of the steel bar, and the volume expands after the steel bar corrodes, which produces a great stress, which seriously damages the structural stability of the concrete guardrail itself, reduces the structural strength of the concrete guardrail, and greatly increases the unsafe fa...

[0002] Some highway bridge concrete guardrails need to be treated with reflective and anti-corrosion treatment. Ordinary reflective materials do not have anti-corrosion function. The roots of concrete guardrails are eroded by rain, snow and snow-melting agents used for snow removal in winter. The corrosion rate of steel bars is accelerated, and the volume of steel bars expands after corrosion, resulting in a large stress, which seriously damages the structural stability of the concrete guardrail itself, reduces the structural strength of the concrete guardrail, and greatly increases the unsafe factors existing on the road

Pasting ceramic tiles on the bridge concrete guardrail can protect the bridge concrete guardrail, but the ceramic tiles in the prior art have low acid and alkali corrosion resistance and do not have light reflection ability
