Description
Technical field
The present invention relates to paint field, particularly relate to a kind of aqueous fluorocarbon coating and preparation method thereof.
Background technology
Ozone is strong oxidizer, may be used for the various impurity in oxidizing water, to reach purifying water effect in water treatment.Along with more and more higher to the requirement of drinking-water quality, ozone is widely used in the water treatment of every profession and trade.The water storage device that the Strong oxdiative ability of ubiquity and the ozone of ozone oxidation application pair and ozone directly contact and coating thereof propose strict requirement.How to develop a kind of ozone proof aqueous fluorocarbon coating most important, ensure that it is under ozone oxidation condition, corrosion-free product and leachable enter in water, therefore, it is possible to eliminate the various risks that may exist, enable water quality treatment meet the demand of drinking-water quality.
Summary of the invention
Technical problem solved by the invention is to overcome in existing solvent-borne type aqueous fluorocarbon coating containing organic solvents such as toluene, dimethylbenzene and ethylbenzene, free vulcabonds (TDI+HDI) etc. are to human body and the effect of environmental toxic evil, existing aqueous fluorocarbon coating is without ozone resistance, or occur that product stability is poor after interpolation ozonidate, the defect that cannot construct, and provide a kind of aqueous fluorocarbon coating and preparation method thereof.Not containing hazardous and noxious substances such as benzene,toluene,xylene, ethylbenzene and free vulcabonds (TDI+HDI) in aqueous fluorocarbon coating of the present invention; ozone resistance is good; pollution-free; there is coatings decoration function and defencive function; the performance that paint film tool ozone resistance, water-tolerant etc. after this coating uses are excellent; and this aqueous fluorocarbon coating of resistance to ozone is non-dangerous goods, strict fire protection requirement be there is no to production, transport, storage, construction.Preparation method's technique of the present invention is simple, has no adverse effects during production to operator, is suitable for industrialization and produces.Aqueous fluorocarbon coating product of the present invention corrosion-free product and leachable under ozone oxidation enter in water, eliminate the various risks that may exist, make water quality meet drinking-water quality requirement, have very wide market outlook.
