Abstract:
An adducts of equalmolar of to lylene- 2, 4- d iisocyanate( TDI)and 2- hydroxyethy l acrylate(BisomerHEA) had been prepared,which is then reacted with OHg roups on surface of nanoa ttapulgite forming an inorganic and organic active intermed iate contain ing double bond.The particle size of inorgan icattapulgite inintermed iatemo lecule structure is 30~ 50 nm.The double bonds can be copolymerized with other doub le bonds ( acrylic acid and acry late) ofmonomers forming nanoattapulg ite/organ ic copolymer.The coatings based on this copolymer show s good corrosion resistance,heat resistance,abrasion resistance andself- cleaning properties.The active intermediate and polymerwere characterized by IR, TGA and SEM.
