Research Of Synthetic Organic Fluorine Modified Styrene-Acrylic Resin And Coating

In recent years, with the rapid development of Marine transportation industry, shippingmanufacture also is able to advance by leaps and bounds. Long-term driving the boats in thesea, because the surface adhesion of Marine biological produce biological of fouling, causehuge economic losses. Therefore, we must improve the antifouling performance of the ship,the hull surface coating a layer of antifouling coatings is the most economic and forthrightmethod.With antifouling paint organic tin of a ban, the research and development of the productcontains can substitute the TBT non-toxic antifouling coatings is imperative. This topic inorder to reduce the surface of the surface coating film for the purpose, will have a low surfacecan characteristics of the atomic introduced fluorine styrene-acrylic resin. In turn discussesthe types, fluorine fluoride monomer monomers, soft hard monomer ratio, epoxy resinquantity and the synthetic process of resin influence on the property of the use of hardnesstester, adhesion pencil equipment on resin coating mechanics performance testing, at the sametime use the infrared detector and molecular weight tester of organic fluorine modification ofsynthesis benzene c resin to chemical bonds and molecular detection, with scanning electronmicroscopy to different formula of film coating apparent morphology observation. Finallyobtained the fluorine resin modified styrene-acrylic the best formula and the best syntheticprocess for: soft and hard monomer ratio0.4~0.6, G04monomer monomers content for15%~18%of the total, epoxy content is2%~4%, and in the80℃~100℃conditions, using splitstep long adding organic fluorinated monomers synthetic process. At the same time, to theresin corresponding antifouling coating was the screening of the preparation technology, andthe modification of nano silicon dioxide, through to the paint film of the conventionalperformance testing and the film surface of observation, concluded that the best formulaantifouling paint for resin35~50, pigments, fillers12~18, nano-silica3~5,30~40of solvent,additives right amount. This topic analyses add nano pigments and fillers and building ofmicro-nano coating surface structure on the film surface and the influence of the dropletscontact Angle, can achieve micron-nanometer class type structure of the film surface contactAngle is far more than a single structure surface contact Angle, by in dalian on the flip chartof coastal experiment, the actual verify the different fluorine content and different amount ofresin coating film antifouling properties.
