Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based fluorocarbon coating and a preparation method thereof. Background technique [0002] Ozone is a strong oxidant, which can be used to oxidize various impurities in water in water treatment to achieve water purification effect. With the higher and higher requirements for drinking water quality, ozone is widely used in water treatment in various industries. The universal application of ozone oxidation and the strong oxidation ability of ozone put forward strict requirements on the water storage equipment and its coatings that are in direct contact with ozone. How to develop an ozone-resistant water-based fluorocarbon coating is very important to ensure that no corrosion products and leachables enter the water under ozone oxidation conditions, so that various possible risks can be eliminated, and the treated water quality can meet drinking water water quality needs.
