| Abstract: |
| By single factor experiment and the orthogonal experiment, organosilicon and epoxy resin modified polyurethane coating was prepared.According to the tensile strength of film, the optimum ratio of TDI and DL2000 of polyurethane was determined, appropriate additive quantity for organosilicon, epoxy resin and plasticizer was obtained, included suitable reaction time and reaction temperature. Infrared spectrum analysis and thermogravimetric analysis were tested for compound modification film, comparing various aspects of the performance with unmodified coating, organsilicone-modified coating and organosilicon and epoxy resin modified polyurethane coating. The result shows that organosilicon and epoxy resin modified polyurethane coating has high strength and adhesion force, low water adsorption rate, high thermal stability and corrosive acid and base resistance. |
