The invention relates to a preparation method of a special epoxy resin with good weather resistance, which includes the preparation of an epoxy resin main agent, the preparation of titanium dioxide and nano-silica carbon nanotubes, the preparation of a strengthening and toughening liquid, and a curing agent. preparation of epoxy resins. The special epoxy resin with good weather resistance prepared by the method of the invention not only has anti-corrosion and high flexural strength, the average flexural strength is equal to or greater than 145MPa, the flexural strength is increased by 24%, and its Tg temperature reaches 190℃‑ 220°C. |
