Abstract

The invention discloses a coating used for expressway guardrails and a preparation method thereof. The coating includes a resin base material, a dispersant, a leveling agent, a cosolvent, a solvent, anano-material, an anti-flash rust agent, and a defoamer. The preparation method includes the steps of: mixing and dispersing the dispersant, the leveling agent, the cosolvent, the solvent, the nano-material and the anti-flash rust agent to prepare a dispersion liquid; adding the resin base material into the dispersion liquid with stirring, and adding a defoaming agent and continuously stirring the mixture to obtain the coating. The preparation method is simple and is free of special large-size equipment. The coating can reach more than 9H in hardness, is wearing resistant and anti-scratching,has excellent electrical insulation property and is high temperature-resistant and ultraviolet aging-resistant, can prevent and resist fouling, and is convenient to clean. The coating is simple in spray coating operation and is free of detachment of the expressway guardrails. The coating is low in cost and is adjustable in drying speed after the spray coating operation.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a coating, in particular to a coating for expressway guardrails and a preparation method thereof. Background technique [0002] The main form of expressway guardrail is semi-rigid guardrail, which is a continuous structure that is spliced ​​with corrugated steel guardrail panels and supported by main columns. [0003] The surface treatment of highway guardrails is divided into two types: hot-dip galvanizing and galvanizing and spraying: hot-dip galvanizing is to immerse the rust-removed steel parts in a zinc solution melted at about 500 ° C, so that the surface of the steel components is attached with a zinc layer, thereby creating a protective effect. For the purpose of anti-corrosion, the process flow is: pickling of finished products - water washing - adding auxiliary plating solution - drying - rack plating - cooling - chemical chemical - cleaning - grinding - hot-dip galvanizin...
