Problems solved by technology

However, the expected life of fluorocarbon coatings cured at room temperature is still far from the design life of railway structures, and it must be maintained and recoated many times during the service life of railway structures
Due to the service characteristics of the closed operation of the railway, the maintenance and repair costs of the railway structures are extremely high

Abstract

The invention provides a room temperature cured fluorocarbon coating modified with nano particles and a preparation method of the room temperature cured fluorocarbon coating. The fluorocarbon coating specifically comprises a component A and a component B, wherein the component A comprises, by weight, 30%-45% of FEVE fluorocarbon resin, 20%-30% of nano-titanium dioxide filler, 2%-10% of discoid nano-europium oxide filler, 15%-20% of a solvent as well as a flatting agent, a defoaming agent, a wetting dispersant, a thixotropic agent and pigment which account for 4%-10% of the total mass of the component A; the component B comprises, in percentage by mass, 10%-50% of isocyanate type curing agents and a solvent. The weather resistance of the fluorocarbon coating is further improved through the higher shielding effect of nano-europium oxide for ultraviolet light and the composite effect of nano-titanium dioxide and nano-europium oxide.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and in particular relates to a nano-particle modified anti-corrosion fluorocarbon coating for normal temperature curing and a preparation method thereof. Background technique [0002] At present, the common room temperature curing fluorocarbon coating is a two-component coating composed of hydroxyl-containing FEVE fluorocarbon resin and isocyanate curing agent. This type of coating uses FEVE fluorocarbon resin as the film-forming substance, which contains a large number of high-energy F-C bonds (bond energy is 480kJ / mol), which can still maintain good stability under the action of light and heat, and has a low surface area. energy, thus exhibiting excellent weather resistance, corrosion resistance and anti-pollution ability. With the continuous changes in policies, regulations and market demands, the related technologies of room temperature curing FEVE fluorocarbon coatings are a...
