Embodiment Construction
[0027] The present invention will be further described below in conjunction with specific embodiments, but not limited thereto.
[0028] Add 100 parts of epoxy silicone resin ES-06 into a reaction vessel equipped with a thermometer, stirring, reflux and dropping device, start stirring and raise the temperature to 70-90°C, and evenly add phosphate ester monomer dropwise within 2-3 hours. The mixed solution of 8 parts of PAM-100 and 40 parts of xylene, and 8 parts of TDI, after the dropwise addition, keep warm for 3 to 4 hours to complete the synthesis of the resin, and obtain the phosphate and isocyanate modified epoxy silicone resin ESPN- 100.
[0029] Phosphate- and fluoropolymer-modified epoxy silicone resins ESPN-200 and ESPN-300 were prepared using phosphate monomers PAM-200 and PAM-300, respectively, and the preparation method was the same as ESPN-100.
