| abstract |
The invention discloses a method for preparing an organic fluorosilicon bionic antifouling resin. 10000g/mol, reacting silicone oil with hydroxyl or amino groups at molecular ends and isocyanate siloxane with triethoxy or trimethoxy end groups to prepare composition 2, by using an average molecular weight of 500-750g/mol, molecular ends Composition 3 is prepared by reacting fluorine oil with hydroxyl groups with isocyanate-based siloxane whose end group is triethoxy or trimethoxy, and synthesizes organic fluorosilicon biomimetic by polycondensation reaction of composition 1, composition 2 and composition 3. Stain-resistant resin. The invention also discloses the organic fluorine silicon biomimetic antifouling resin prepared by the method, which has the advantages of low surface energy of organic fluorine, low elastic modulus of organic silicon, strong adhesion of polyurethane, etc., and has great advantages in the field of marine antifouling. Broad application prospects. |
