Manufacturing Method of Silane Compound for Fixing TiO2 Nanofiber and Coating agent Using the Silane Compound for Fixing TiO2 Nanofiber

摘要

The present invention is a method for preparing a silane fixing agent for coating and fixing titanium dioxide nanofibers on a substrate surface so that long-term stability and excellent adhesion properties are secured, and titanium dioxide nanofibers are effectively used in the silane fixing agent prepared by the manufacturing method. It relates to a dispersion-fixed photocatalytic reaction coating agent. The method for preparing a silane fixative for fixing titanium dioxide nanofibers according to the present invention includes 160 to 460 parts by weight of silane, 400 to 780 parts by weight of ethanol, 15 to 50 parts by weight of acetic acid, and water based on 1,000 parts by weight of the silane fixing agent to be prepared. Material preparation step of preparing 45 to 90 parts by weight; The prepared material is divided into a solution A containing silane and a solution B containing water, but solution A is prepared by mixing silane and ethanol or silane, ethanol, and acetic acid, and solution B is mixing water and acetic acid or water. Material classification step of preparing by mixing and ethanol; Heating and stirring step of stirring while maintaining the heating solution B at 50 ~ 60 ℃; Addition and stirring step of maintaining the stirring by adding Solution A to Solution B while heating and stirring; And a cooling step of cooling at room temperature after 24 hours of maintaining the addition stirring.
