Modified FEVE fluorocarbon resin coating

Abstract

The invention discloses a modified FEVE fluorocarbon resin coating. The modified FEVE fluorocarbon resin coating comprises the following raw materials in parts by weight: 20 to 50 parts of modified FEVE fluorocarbon resin, 30 to 40 parts of epoxy modified alkyd resin, 10 to 25 parts of acrylic modified alkyd resin, 2 to 6 parts of melamine resin, 5 to 10 parts of isocyanate curing agent, 5 to 12 parts of high-substituted hydroxy propyl cellulose, 0.5 to 1.5 parts of sodium dodecyl benzene sulfonate, 2 to 8 parts of polyoxyethylene polyoxypropylene ether, 10 to 18 parts of super fine calcium carbonate, 10 to 16 parts of gas-phase silicon dioxide, 2 to 9 parts of kaolin, 5 to 10 parts of organobentonite, 1.5 to 2.8 parts of graphene, 0.5 to 1.8 parts of polydimethylsiloxane, 0.5 to 1.5 parts of polyamide wax, 0.5 to 1.5 parts of calcium sulfonate, 5 to 10 parts of amyl acetate, 2 to 10 parts of propanediol, 3 to 6 parts of methyl ethyl ketone and 20 to 55 parts of water. The modified FEVE fluorocarbon resin coating is excellent in adhesion capability, resistant to corrosion and good in mould-proof effect.

Description

technical field [0001] The invention relates to the technical field of alkyd resin coatings, in particular to a modified FEVE fluorocarbon resin coating. Background technique [0002] Due to the application of ships in the marine environment, they are subject to strong erosion of salt spray, moisture, sunlight, sea wind, etc., especially the environment of high temperature, high humidity, and high salt spray in the South China Sea is even harsher. Many ships have rusty spots on the cast iron surface In addition, the most suitable growth and reproduction conditions for mold are temperature 28-30°C and humidity about 80%. Therefore, the marine environment is the best breeding condition for mold. Under such harsh environmental factors, it will inevitably cause severe corrosion of the ship and affect its quality. Long-term stable and reliable work, the current protection of ships mainly includes alkyd, acrylic and polyurethane paints, etc., which can protect against corrosion, b...

[0002] Due to the application of ships in the marine environment, they are subject to strong erosion of salt spray, moisture, sunlight, sea wind, etc., especially the environment of high temperature, high humidity, and high salt spray in the South China Sea is even harsher. Many ships have rusty spots on the cast iron surface In addition, the most suitable growth and reproduction conditions for mold are temperature 28-30°C and humidity about 80%. Therefore, the marine environment is the best breeding condition for mold. Under such harsh environmental factors, it will inevitably cause severe corrosion of the ship and affect its quality. Long-term stable and reliable work, the current protection of ships mainly includes alkyd, acrylic and polyurethane paints, etc., which can protect against corrosion, but the adhesion cannot meet the harsh requirements of the extremely harsh marine environment. To prepare a coating with excellent adhesion, corrosion resistance and anti-mildew effect has become a technical problem to be solved at present
