Problems solved by technology

[0004] Highway guardrails generally use galvanized technology. Without other protective treatments, when they are in harsh outdoor environments, they are exposed to sunlight, wind and rain erosion, thermal expansion and contraction, automobile exhaust, and acid rain and salt spray. In the process of use, the zinc layer is worn out, loses its luster, loses its anti-corrosion ability, reduces the decorative appearance, and reduces the protective ability of the guardrail.

preparation example Construction

[0076] The preparation method of fluorine-modified acrylic acid emulsion is as follows:

[0077] S1: In a four-necked flask equipped with a stirring and reflux condenser, add 200 parts by mass of deionized water, 2 parts by mass of sodium lauryl sulfate and 2 parts by mass of OP-10 emulsifier, and stir for 30 minutes. An emulsifier solution is obtained.

[0078] S2: In a glass reactor, 17 parts by mass of perfluorooctylethyl methacrylate, 50 parts by mass of butyl methacrylate and 3 parts by mass of methacrylic acid were mixed uniformly, and the 100 parts obtained in S1 Parts by mass of the emulsifier solution was added into a glass reactor, stirred evenly, and ultrasonically emulsified for 1 hour to obtain a monomer pre-emulsion.

[0079] S3: Heat 100 parts by mass of emulsifier solution to 80° C., and add 100 parts by mass of monomer pre-emulsion and 2 parts by mass of potassium persulfate aqueous solution (4 wt %) dropwise under nitrogen protection. The dropwise addition ...

The water-based fluorinated graphene paint of the present invention has good weather resistance and physical properties, and simultaneously has anti-fouling and self-cleaning capabilities, excellent anti-corrosion and anti-rust performance, and is suitable for surface treatment of expressway guardrails.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based fluorinated graphene coating and a preparation method and application thereof. Background technique [0002] Highway guardrail is the main form of semi-rigid guardrail, which is a continuous structure that is spliced ​​with corrugated steel guardrail panels and supported by main columns. The function of absorbing energy when the vehicle collides with the highway guardrail is not easy to be crashed, and at the same time it can play a very good role in protecting the vehicle and the passengers. [0003] The surface treatment of highway guardrails can be divided into two types: hot-dip galvanizing and galvanized spraying, among which galvanizing can be divided into hot-dip galvanizing and cold-dip galvanizing. Hot-dip galvanizing is to immerse the rust-removed steel parts in the zinc solution at 500 ° C, so that the surface of the steel components is attached with a ...
