| titleOfInvention | Using SiO2Method for preparing super-hydrophobic microporous membrane on surface of particle modified polyurethane |
| abstract | The invention discloses a method for preparing a silicon dioxide (SiO) 2 A method for preparing a super-hydrophobic microporous membrane on the surface of particle modified polyurethane. The method of the invention adopts polyisocyanate to graft free isocyanate group on the surface of polyurethane, then the group reacts with gamma-aminopropyl silane to generate a silicon oxide layer on the surface of polyurethane, and finally the super-hydrophobic SiO is generated on the fiber surface of a polyurethane microporous membrane by hydrolyzing tetraethoxysilane and hydrophobically modifying hexadecyl trimethoxy silane 2 And (4) granulating to obtain the super-hydrophobic polyurethane microporous membrane. The method can realize the mass production of the super-hydrophobic polyurethane microporous membrane, has short production period and low production cost, and the obtained membrane has a micron porous structure and has excellent comprehensive properties of water resistance, air permeability, moisture permeability, self-cleaning and the like. |
