ActiveCN103554501AGood solvent resistanceGood weather resistanceTetramethylammonium hydroxideSolvent
The invention discloses linear or body fluorine modified polysiloxane and a preparation method thereof. The preparation method disclosed by the invention mainly comprises the following steps of: by taking quaternary ammonium base (such as tetramethylammonium hydroxide (TMAH)) siloxanolate or quaternary phosphorus alkali (such as tetrabutyl phosphorus hydroxide (TBPH)) siloxanolate as the catalyst, taking fluorine-containing cyclosiloxane (such as trifluoropropylmethyl cyclotrisiloxane (D3F)), alkyl cyclosiloxane (such as hexamethyl cyclotrisiloxane (D3), octamethyl cyclotetrasiloxane (D4) or decamethyl cyclopentasiloxane (D5)) or alkyl polycyclosiloxane (bi(heptamethyl cyclotetramethoxy)-ethane(bis-D4)) as the raw material, carrying out ring opening polymerization, and obtaining the linear or body fluorine modified organosilicon material. The preparation method of the linear or body fluorine modified organosilicon material disclosed by the invention is simple in preparation process and low in cost; furthermore, the molecular weight of the prepared product can be adjusted according to requirements; the linear or body fluorine modified organosilicon material has excellent antifouling property, solvent resistance, weather fastness and heat stability and has strong industrialization ability and application prospect.
