preparation example Construction

[0034] The preparation method of the anti-corrosion and anti-fouling integrated coating for coating repair of the present invention comprises the following steps:

[0035] (1) Preparation of anti-corrosion components: first mix epoxy resin, modified epoxy resin, bifunctional reactive diluent, fumed silica and anti-rust pigments and fillers, disperse for 20-40 minutes, add solvent to adjust viscosity, and continue to disperse After 3-5 hours, the material can be discharged after being fully dispersed and evenly distributed. After the material is discharged, it will be packaged separately with the amine curing agent.

[0036] (2) Preparation of antifouling components: first add hydroxy silicone resin, phenylmethyl silicone oil, fumed silica and antifouling additives to mix, disperse for 20-40 minutes, add solvent to adjust viscosity, continue to disperse for 3-5 hours , It can be discharged after being fully dispersed and uniform. When using, add silane crosslinking agent in pro...

Abstract

An anti-corrosion and anti-fouling integrated coating for coating restoration and a preparation method thereof. The coating is composed of an anti-corrosion component and an anti-fouling component that are separately packaged and mixed during use. The anti-corrosion component includes epoxy resin, Modified epoxy resin, bifunctional reactive diluent, fumed silica, anti-rust pigments and fillers, solvent and amine curing agent added during use; the anti-fouling components include hydroxyl-terminated silicone resin, phenyl formaldehyde Base silicone oil, anti-fouling additives, solvents and silane crosslinking agent added during use; the mass ratio of anti-corrosion components and anti-fouling components is 3:1-1:3. The anti-corrosion and anti-fouling coating has a film thickness of more than 600 μm at one time, is resistant to immersion in salt water at 40°C for 90 days, and has an anti-fouling effect of more than one year. It can be used for damaged parts of the coating below the waterline of the hull of large ships, fishing boats, etc., for rapid repair, to achieve anti-corrosion and anti-fouling functions in one coating, reduce the number of construction steps, and reduce maintenance costs.

Description

technical field [0001] The invention relates to a coating paint, in particular to an anti-corrosion and anti-fouling integrated paint for coating repair and a preparation method thereof. Background technique [0002] In the anti-corrosion and anti-fouling coating system below the waterline of the ship, a multi-layer system is required to achieve anti-corrosion and anti-fouling functions. During the partial maintenance of the ship, the maintenance of the surface coating part requires 2 coats of primer and 1 coat of connecting paint. 2-3 coats of antifouling paint, each layer needs to be applied separately, and there are strict construction intervals. This maintenance method has complex procedures, long maintenance cycle, huge docking fee and high maintenance cost in the maintenance process. [0003] In 1976, Funke et al. proposed a new concept - self-layered coatings. The self-layering coating is composed of one (or more) different compatible polymers. After the coating is ...
